00:00:00.000 --> 00:00:02.960
Anna: Hello and welcome to Astronomy Daily. I'm
1
00:00:02.960 --> 00:00:03.520
Anna.
2
00:00:03.760 --> 00:00:06.746
Avery: And I'm avery. It's Thursday, July 2,
3
00:00:06.894 --> 00:00:09.840
2026, and we've got a properly mixed bag for
4
00:00:09.840 --> 00:00:10.240
you today.
5
00:00:10.560 --> 00:00:13.160
Anna: A solar flare that could light up the sky for
6
00:00:13.160 --> 00:00:16.040
the Fourth of July weekend. A planet that's
7
00:00:16.040 --> 00:00:18.720
breaking all the hot Jupiter rules, and
8
00:00:18.800 --> 00:00:21.520
NASA making a very cheeky promise
9
00:00:21.520 --> 00:00:23.760
involving a soccer ball and the moon.
10
00:00:24.160 --> 00:00:26.400
Avery: Plus, we're circling back on a story that
11
00:00:26.400 --> 00:00:28.640
quietly reshaped how we think about dark
12
00:00:28.640 --> 00:00:30.010
matter. Let's get into it.
13
00:00:30.330 --> 00:00:32.810
Anna: Quick update on the Swift rescue mission,
14
00:00:32.810 --> 00:00:34.970
because if you were with us yesterday, you'll
15
00:00:34.970 --> 00:00:37.130
remember this one just won't lift off.
16
00:00:37.610 --> 00:00:40.210
Avery: Right, Catalyst Link spacecraft
17
00:00:40.210 --> 00:00:43.210
riding the very last Pegasus XL rocket
18
00:00:43.210 --> 00:00:45.610
has now been scrubbed twice for weather.
19
00:00:45.850 --> 00:00:48.570
First, it slipped from June 30 to July 1.
20
00:00:48.970 --> 00:00:51.610
Then from July 1 to today, targeting
21
00:00:51.610 --> 00:00:52.890
5O9 Eastern.
22
00:00:53.370 --> 00:00:55.890
Anna: So as of when, we're recording, it's a real
23
00:00:55.890 --> 00:00:58.830
nail biter. Swift is still up there, still
24
00:00:58.830 --> 00:01:01.750
safe for now. And Link is still waiting for
25
00:01:01.750 --> 00:01:04.350
its shot at making history as the first
26
00:01:04.350 --> 00:01:07.230
commercial spacecraft to grapple an uncrewed
27
00:01:07.230 --> 00:01:08.350
government satellite.
28
00:01:08.510 --> 00:01:10.430
Avery: We'll keep tracking it and give you the real
29
00:01:10.430 --> 00:01:12.830
result the moment we have it. For now.
30
00:01:12.989 --> 00:01:14.350
Patience, Pegasus.
31
00:01:14.750 --> 00:01:17.150
Now for something the sun actually delivered
32
00:01:17.150 --> 00:01:19.704
on. On June 30, Sunspot
33
00:01:19.876 --> 00:01:22.832
Region AR479 let loose an x
34
00:01:22.948 --> 00:01:25.880
1.1 flare, the most powerful class there
35
00:01:25.880 --> 00:01:26.200
is.
36
00:01:26.520 --> 00:01:29.280
Anna: It triggered strong radio blackouts across
37
00:01:29.280 --> 00:01:32.080
the daylight side of Earth, and it launched a
38
00:01:32.080 --> 00:01:34.720
full halo coronal mass ejection heading our
39
00:01:34.720 --> 00:01:35.000
way.
40
00:01:35.400 --> 00:01:37.720
Avery: NOAA Space Weather Prediction center has
41
00:01:37.720 --> 00:01:40.600
issued a G2 moderate geomagnetic
42
00:01:40.600 --> 00:01:42.920
storm watch for July 3, meaning
43
00:01:42.920 --> 00:01:45.440
Aurora could be visible much further from the
44
00:01:45.440 --> 00:01:46.440
poles than usual.
45
00:01:46.760 --> 00:01:49.000
Anna: For our friends in the Northern Hemisphere,
46
00:01:49.080 --> 00:01:51.640
that could mean lights as far south as New
47
00:01:51.640 --> 00:01:54.120
York, Wisconsin and Washington State,
48
00:01:54.680 --> 00:01:57.000
just in time for July 4th fireworks.
49
00:01:57.240 --> 00:01:59.400
Avery: And for us down, um, under, it's the opposite
50
00:01:59.400 --> 00:02:01.800
season. Deep winter darkness, which is
51
00:02:01.800 --> 00:02:04.400
honestly prime Aurora australis viewing
52
00:02:04.400 --> 00:02:06.360
weather. If the geometry cooperates.
53
00:02:06.920 --> 00:02:09.760
Anna: Solar activity remains elevated too, with a
54
00:02:09.760 --> 00:02:12.440
slight chance of further X class flares from
55
00:02:12.440 --> 00:02:14.960
three separate active regions. Keep your
56
00:02:14.960 --> 00:02:15.800
cameras charged.
57
00:02:16.280 --> 00:02:19.200
Avery: Next up, time for a proper mystery. Meet
58
00:02:19.200 --> 00:02:22.160
Corot 2B, a gas giant three and a
59
00:02:22.160 --> 00:02:24.600
half times the mass of Jupiter orbiting its
60
00:02:24.600 --> 00:02:26.200
star in just 41 hours.
61
00:02:26.820 --> 00:02:29.140
Anna: Hot Jupiters like this are almost always
62
00:02:29.220 --> 00:02:32.220
tidally locked. One side permanently cooking
63
00:02:32.220 --> 00:02:34.900
in starlight, the other in permanent night.
64
00:02:35.060 --> 00:02:37.620
With a hotspot that shifts in a predictable
65
00:02:37.620 --> 00:02:39.620
direction thanks to eastward winds.
66
00:02:39.940 --> 00:02:42.940
Avery: Coro2b has had astronomers scratching their
67
00:02:42.940 --> 00:02:45.500
heads for eight years because its hotspot is
68
00:02:45.500 --> 00:02:48.500
on the Wrong side entirely. Now, new research
69
00:02:48.580 --> 00:02:50.980
led by Aurora Caselli at the NASA
70
00:02:50.980 --> 00:02:53.300
Exoplanet Science Institute has cracked.
71
00:02:53.300 --> 00:02:55.820
Anna: It turns out this planet just isn't
72
00:02:55.820 --> 00:02:58.500
tidally locked. Its day is about three
73
00:02:58.500 --> 00:03:01.300
Earth days long, almost double the length of
74
00:03:01.300 --> 00:03:03.820
its year, which is only around one and a half
75
00:03:03.820 --> 00:03:04.180
days.
76
00:03:04.660 --> 00:03:06.900
Avery: So by the time it finishes spinning once,
77
00:03:06.900 --> 00:03:09.380
it's already lapped its own star nearly
78
00:03:09.380 --> 00:03:12.140
twice. That's genuinely bizarre for a
79
00:03:12.140 --> 00:03:13.620
planet this close to its host.
80
00:03:14.020 --> 00:03:16.820
Anna: As Caselli put it, a, uh, one size fits all
81
00:03:16.820 --> 00:03:19.260
model just doesn't work. Even for planets
82
00:03:19.260 --> 00:03:21.890
we've studied for years. There goes another
83
00:03:21.890 --> 00:03:22.850
tidy theory.
84
00:03:23.170 --> 00:03:25.690
Avery: Our next story today takes us up to Florida,
85
00:03:25.690 --> 00:03:27.970
where United Launch alliance sent another
86
00:03:28.130 --> 00:03:30.970
29Amazon Leo broadband satellites
87
00:03:30.970 --> 00:03:33.010
into orbit in the small hours of this
88
00:03:33.010 --> 00:03:36.010
morning. Liftoff at 1224 Eastern from
89
00:03:36.010 --> 00:03:36.930
Cape Canaveral.
90
00:03:37.250 --> 00:03:39.930
Anna: This one carries some history with it. It's
91
00:03:39.930 --> 00:03:42.610
the eighth and final Atlas V5 flight
92
00:03:42.610 --> 00:03:45.330
dedicated to Amazon Leo. From here, the
93
00:03:45.330 --> 00:03:47.970
constellation shifts over to Ula's newer
94
00:03:47.970 --> 00:03:49.550
Vulcan Centaur rocket launch.
95
00:03:49.860 --> 00:03:52.260
Avery: Amazon's building toward more than 3,000
96
00:03:52.260 --> 00:03:54.740
satellites for its Low Earth orbit Internet
97
00:03:54.740 --> 00:03:57.300
network. Competing head on with SpaceX's
98
00:03:57.300 --> 00:03:59.820
Starlink, this launch pushes the total in
99
00:03:59.820 --> 00:04:02.180
orbit past the 390 mark.
100
00:04:02.580 --> 00:04:05.300
Anna: It's also worth noting the clock is ticking.
101
00:04:05.540 --> 00:04:08.540
The FCC requires Amazon to have half that
102
00:04:08.540 --> 00:04:10.740
constellation flying by the end of this
103
00:04:10.740 --> 00:04:13.220
month. So expect the launch pace to stay
104
00:04:13.220 --> 00:04:13.700
brisk.
105
00:04:14.100 --> 00:04:16.540
Avery: Our next story is for all patriotic
106
00:04:16.540 --> 00:04:19.540
Americans. Well, sort of. With
107
00:04:19.540 --> 00:04:22.540
America's 250th birthday coming up on the
108
00:04:22.540 --> 00:04:25.420
4th of July, NASA's Chandra X Ray
109
00:04:25.420 --> 00:04:27.740
Observatory has given the country a rather
110
00:04:27.740 --> 00:04:29.060
spectacular gift.
111
00:04:29.780 --> 00:04:32.380
Anna: Four new composite images, each
112
00:04:32.380 --> 00:04:34.580
rendered in red, white and blue.
113
00:04:34.820 --> 00:04:37.380
Combining Chandra's X ray vision with light
114
00:04:37.380 --> 00:04:40.340
from Hubble Webb and ground based telescopes,
115
00:04:40.580 --> 00:04:43.540
Avery: the lineup includes the Cassiopeia, a
116
00:04:43.620 --> 00:04:45.990
supernova remnant, the star
117
00:04:46.150 --> 00:04:48.470
forming nebula NGC
118
00:04:48.710 --> 00:04:51.270
3603, the
119
00:04:51.270 --> 00:04:54.230
spiral galaxy Messier 94,
120
00:04:54.630 --> 00:04:56.350
and the galaxy cluster
121
00:04:56.350 --> 00:04:58.230
ZWCL
122
00:04:58.390 --> 00:05:00.190
0024
123
00:05:00.590 --> 00:05:03.590
1652, where Hubble
124
00:05:03.590 --> 00:05:06.310
has mapped out dark matter's fingerprints.
125
00:05:06.550 --> 00:05:09.270
Anna: And it's not just visual. Chandra's team
126
00:05:09.350 --> 00:05:11.830
also released three new sonifications,
127
00:05:12.380 --> 00:05:15.180
turning the X ray data into sound so you can
128
00:05:15.180 --> 00:05:17.820
genuinely listen to a supernova remnant.
129
00:05:18.460 --> 00:05:21.220
Avery: A lovely patriotic little reminder that the
130
00:05:21.220 --> 00:05:23.740
universe doesn't know about borders. But it
131
00:05:23.740 --> 00:05:25.660
sure looks good in the right color scheme.
132
00:05:26.380 --> 00:05:29.140
Anna: Now, a bit of a different segment. A couple
133
00:05:29.140 --> 00:05:31.740
of weeks back, a genuinely strange discovery
134
00:05:31.740 --> 00:05:34.420
came out of Yale and the Keck Observatory and
135
00:05:34.420 --> 00:05:36.580
it's stuck with us. So we wanted to circle
136
00:05:36.580 --> 00:05:38.220
back and make sure you'd heard it too.
137
00:05:39.050 --> 00:05:41.530
Avery: Back in Mid June, astronomers confirmed a
138
00:05:41.530 --> 00:05:44.170
third galaxy that appears to have essentially
139
00:05:44.330 --> 00:05:46.770
zero dark matter. It's called
140
00:05:46.770 --> 00:05:49.450
DF9. Sitting alongside two previous
141
00:05:49.450 --> 00:05:52.010
oddballs, DF2 and DF4.
142
00:05:52.570 --> 00:05:55.290
Anna: All three line up in a tight, straight
143
00:05:55.290 --> 00:05:58.050
trail of galaxies. And that alignment is the
144
00:05:58.050 --> 00:06:00.850
real kicker. It suggests they didn't form the
145
00:06:00.850 --> 00:06:03.770
normal way. Tucked inside a dark matter halo.
146
00:06:04.340 --> 00:06:07.060
Avery: The leading idea is a bullet dwarf collision,
147
00:06:07.300 --> 00:06:10.180
a violent high speed crash between galaxies
148
00:06:10.180 --> 00:06:12.620
billions of years ago that literally stripped
149
00:06:12.620 --> 00:06:15.220
the ordinary gas away from its dark matter,
150
00:06:15.460 --> 00:06:17.860
letting new galaxies form from that gas
151
00:06:17.860 --> 00:06:18.260
alone.
152
00:06:18.900 --> 00:06:21.340
Anna: Using the Keck Observatory's Cosmic Web
153
00:06:21.340 --> 00:06:24.260
Imager, the team led by Yale's Michael Keim
154
00:06:24.260 --> 00:06:26.980
measured DF9's mass by tracking how its
155
00:06:26.980 --> 00:06:29.380
stars move. And the total came out almost
156
00:06:29.460 --> 00:06:32.360
exactly matching the visible matter. No room
157
00:06:32.360 --> 00:06:34.120
left over for anything invisible.
158
00:06:34.680 --> 00:06:36.800
Avery: It's a big deal because it's some of the
159
00:06:36.800 --> 00:06:38.840
clearest evidence yet that dark matter
160
00:06:38.840 --> 00:06:41.480
behaves like an actual physical substance,
161
00:06:41.720 --> 00:06:43.960
one that can genuinely be separated from
162
00:06:43.960 --> 00:06:46.080
ordinary matter in the right violent
163
00:06:46.080 --> 00:06:46.760
circumstances.
164
00:06:47.480 --> 00:06:49.880
Anna: So if this one slipped past you when it first
165
00:06:49.880 --> 00:06:52.360
broke, now you're all caught up, and it's a
166
00:06:52.360 --> 00:06:55.280
great excuse to look up DF2, DF4 and
167
00:06:55.280 --> 00:06:56.360
DF9 together.
168
00:06:56.520 --> 00:06:59.410
Next clear night. Well, with a very big
169
00:06:59.410 --> 00:07:01.170
telescope, let's
170
00:07:01.170 --> 00:07:03.050
Avery: finish on something completely different.
171
00:07:03.610 --> 00:07:06.610
NASA administrator Jared Isaacman has made a
172
00:07:06.610 --> 00:07:08.930
promise. If the United states wins the
173
00:07:08.930 --> 00:07:11.810
2026 FIFA World Cup, NASA will
174
00:07:11.810 --> 00:07:13.610
send a soccer ball to the moon.
175
00:07:14.330 --> 00:07:17.170
Anna: This is not a joke. Apparently, Isaacman
176
00:07:17.170 --> 00:07:19.570
made the pledge alongside Carlos Garcia
177
00:07:19.570 --> 00:07:22.170
galan, who runs NASA's moon base program,
178
00:07:22.330 --> 00:07:24.730
during a briefing about lunar lander plans.
179
00:07:25.520 --> 00:07:28.480
Avery: The plan is to one up Apollo 14 astronaut
180
00:07:28.480 --> 00:07:31.440
Alan Shepard, who famously smuggled a golf
181
00:07:31.440 --> 00:07:33.880
club and a couple of balls to the moon back
182
00:07:33.880 --> 00:07:36.800
in 1971 for a very short round
183
00:07:36.800 --> 00:07:37.760
of lunar golf.
184
00:07:38.240 --> 00:07:40.920
Anna: NASA's already sent an official World cup
185
00:07:40.920 --> 00:07:43.400
ball to the space station so astronauts could
186
00:07:43.400 --> 00:07:46.040
test their zero gravity footwork. This would
187
00:07:46.040 --> 00:07:48.360
be the away leg, Garcia.
188
00:07:48.360 --> 00:07:50.400
Avery: Galan says the ball is light enough that
189
00:07:50.400 --> 00:07:52.760
finding room on a future lander payload won't
190
00:07:52.760 --> 00:07:55.190
be a problem. So really, it's all down to
191
00:07:55.190 --> 00:07:56.310
Team USA now.
192
00:07:56.870 --> 00:07:57.830
Anna: No pressure.
193
00:07:58.310 --> 00:08:00.230
Avery: And, um, that's a wrap for today's episode.
194
00:08:00.630 --> 00:08:02.710
Anna: If swift's launch finally goes ahead
195
00:08:02.710 --> 00:08:04.790
overnight, we'll bring you the result first
196
00:08:04.790 --> 00:08:07.230
thing tomorrow. Until then, clear skies,
197
00:08:07.230 --> 00:08:07.590
everyone.
198
00:08:08.230 --> 00:08:10.270
Avery: And keep an eye out for Aurora this weekend.
199
00:08:10.270 --> 00:08:11.750
You might just catch a show.
200
00:08:12.310 --> 00:08:14.550
Anna: We'll do it all again tomorrow. Bye.
201
00:08:17.990 --> 00:08:18.550
Stories,
202
00:08:21.120 --> 00:08:21.360
Love.
203
00:08:25.920 --> 00:08:27.360
Avery: Story, soul.
0
00:00:00.000 --> 00:00:02.960
Anna: Hello and welcome to Astronomy Daily. I'm
1
00:00:02.960 --> 00:00:03.520
Anna.
2
00:00:03.760 --> 00:00:06.746
Avery: And I'm avery. It's Thursday, July 2,
3
00:00:06.894 --> 00:00:09.840
2026, and we've got a properly mixed bag for
4
00:00:09.840 --> 00:00:10.240
you today.
5
00:00:10.560 --> 00:00:13.160
Anna: A solar flare that could light up the sky for
6
00:00:13.160 --> 00:00:16.040
the Fourth of July weekend. A planet that's
7
00:00:16.040 --> 00:00:18.720
breaking all the hot Jupiter rules, and
8
00:00:18.800 --> 00:00:21.520
NASA making a very cheeky promise
9
00:00:21.520 --> 00:00:23.760
involving a soccer ball and the moon.
10
00:00:24.160 --> 00:00:26.400
Avery: Plus, we're circling back on a story that
11
00:00:26.400 --> 00:00:28.640
quietly reshaped how we think about dark
12
00:00:28.640 --> 00:00:30.010
matter. Let's get into it.
13
00:00:30.330 --> 00:00:32.810
Anna: Quick update on the Swift rescue mission,
14
00:00:32.810 --> 00:00:34.970
because if you were with us yesterday, you'll
15
00:00:34.970 --> 00:00:37.130
remember this one just won't lift off.
16
00:00:37.610 --> 00:00:40.210
Avery: Right, Catalyst Link spacecraft
17
00:00:40.210 --> 00:00:43.210
riding the very last Pegasus XL rocket
18
00:00:43.210 --> 00:00:45.610
has now been scrubbed twice for weather.
19
00:00:45.850 --> 00:00:48.570
First, it slipped from June 30 to July 1.
20
00:00:48.970 --> 00:00:51.610
Then from July 1 to today, targeting
21
00:00:51.610 --> 00:00:52.890
5O9 Eastern.
22
00:00:53.370 --> 00:00:55.890
Anna: So as of when, we're recording, it's a real
23
00:00:55.890 --> 00:00:58.830
nail biter. Swift is still up there, still
24
00:00:58.830 --> 00:01:01.750
safe for now. And Link is still waiting for
25
00:01:01.750 --> 00:01:04.350
its shot at making history as the first
26
00:01:04.350 --> 00:01:07.230
commercial spacecraft to grapple an uncrewed
27
00:01:07.230 --> 00:01:08.350
government satellite.
28
00:01:08.510 --> 00:01:10.430
Avery: We'll keep tracking it and give you the real
29
00:01:10.430 --> 00:01:12.830
result the moment we have it. For now.
30
00:01:12.989 --> 00:01:14.350
Patience, Pegasus.
31
00:01:14.750 --> 00:01:17.150
Now for something the sun actually delivered
32
00:01:17.150 --> 00:01:19.704
on. On June 30, Sunspot
33
00:01:19.876 --> 00:01:22.832
Region AR479 let loose an x
34
00:01:22.948 --> 00:01:25.880
1.1 flare, the most powerful class there
35
00:01:25.880 --> 00:01:26.200
is.
36
00:01:26.520 --> 00:01:29.280
Anna: It triggered strong radio blackouts across
37
00:01:29.280 --> 00:01:32.080
the daylight side of Earth, and it launched a
38
00:01:32.080 --> 00:01:34.720
full halo coronal mass ejection heading our
39
00:01:34.720 --> 00:01:35.000
way.
40
00:01:35.400 --> 00:01:37.720
Avery: NOAA Space Weather Prediction center has
41
00:01:37.720 --> 00:01:40.600
issued a G2 moderate geomagnetic
42
00:01:40.600 --> 00:01:42.920
storm watch for July 3, meaning
43
00:01:42.920 --> 00:01:45.440
Aurora could be visible much further from the
44
00:01:45.440 --> 00:01:46.440
poles than usual.
45
00:01:46.760 --> 00:01:49.000
Anna: For our friends in the Northern Hemisphere,
46
00:01:49.080 --> 00:01:51.640
that could mean lights as far south as New
47
00:01:51.640 --> 00:01:54.120
York, Wisconsin and Washington State,
48
00:01:54.680 --> 00:01:57.000
just in time for July 4th fireworks.
49
00:01:57.240 --> 00:01:59.400
Avery: And for us down, um, under, it's the opposite
50
00:01:59.400 --> 00:02:01.800
season. Deep winter darkness, which is
51
00:02:01.800 --> 00:02:04.400
honestly prime Aurora australis viewing
52
00:02:04.400 --> 00:02:06.360
weather. If the geometry cooperates.
53
00:02:06.920 --> 00:02:09.760
Anna: Solar activity remains elevated too, with a
54
00:02:09.760 --> 00:02:12.440
slight chance of further X class flares from
55
00:02:12.440 --> 00:02:14.960
three separate active regions. Keep your
56
00:02:14.960 --> 00:02:15.800
cameras charged.
57
00:02:16.280 --> 00:02:19.200
Avery: Next up, time for a proper mystery. Meet
58
00:02:19.200 --> 00:02:22.160
Corot 2B, a gas giant three and a
59
00:02:22.160 --> 00:02:24.600
half times the mass of Jupiter orbiting its
60
00:02:24.600 --> 00:02:26.200
star in just 41 hours.
61
00:02:26.820 --> 00:02:29.140
Anna: Hot Jupiters like this are almost always
62
00:02:29.220 --> 00:02:32.220
tidally locked. One side permanently cooking
63
00:02:32.220 --> 00:02:34.900
in starlight, the other in permanent night.
64
00:02:35.060 --> 00:02:37.620
With a hotspot that shifts in a predictable
65
00:02:37.620 --> 00:02:39.620
direction thanks to eastward winds.
66
00:02:39.940 --> 00:02:42.940
Avery: Coro2b has had astronomers scratching their
67
00:02:42.940 --> 00:02:45.500
heads for eight years because its hotspot is
68
00:02:45.500 --> 00:02:48.500
on the Wrong side entirely. Now, new research
69
00:02:48.580 --> 00:02:50.980
led by Aurora Caselli at the NASA
70
00:02:50.980 --> 00:02:53.300
Exoplanet Science Institute has cracked.
71
00:02:53.300 --> 00:02:55.820
Anna: It turns out this planet just isn't
72
00:02:55.820 --> 00:02:58.500
tidally locked. Its day is about three
73
00:02:58.500 --> 00:03:01.300
Earth days long, almost double the length of
74
00:03:01.300 --> 00:03:03.820
its year, which is only around one and a half
75
00:03:03.820 --> 00:03:04.180
days.
76
00:03:04.660 --> 00:03:06.900
Avery: So by the time it finishes spinning once,
77
00:03:06.900 --> 00:03:09.380
it's already lapped its own star nearly
78
00:03:09.380 --> 00:03:12.140
twice. That's genuinely bizarre for a
79
00:03:12.140 --> 00:03:13.620
planet this close to its host.
80
00:03:14.020 --> 00:03:16.820
Anna: As Caselli put it, a, uh, one size fits all
81
00:03:16.820 --> 00:03:19.260
model just doesn't work. Even for planets
82
00:03:19.260 --> 00:03:21.890
we've studied for years. There goes another
83
00:03:21.890 --> 00:03:22.850
tidy theory.
84
00:03:23.170 --> 00:03:25.690
Avery: Our next story today takes us up to Florida,
85
00:03:25.690 --> 00:03:27.970
where United Launch alliance sent another
86
00:03:28.130 --> 00:03:30.970
29Amazon Leo broadband satellites
87
00:03:30.970 --> 00:03:33.010
into orbit in the small hours of this
88
00:03:33.010 --> 00:03:36.010
morning. Liftoff at 1224 Eastern from
89
00:03:36.010 --> 00:03:36.930
Cape Canaveral.
90
00:03:37.250 --> 00:03:39.930
Anna: This one carries some history with it. It's
91
00:03:39.930 --> 00:03:42.610
the eighth and final Atlas V5 flight
92
00:03:42.610 --> 00:03:45.330
dedicated to Amazon Leo. From here, the
93
00:03:45.330 --> 00:03:47.970
constellation shifts over to Ula's newer
94
00:03:47.970 --> 00:03:49.550
Vulcan Centaur rocket launch.
95
00:03:49.860 --> 00:03:52.260
Avery: Amazon's building toward more than 3,000
96
00:03:52.260 --> 00:03:54.740
satellites for its Low Earth orbit Internet
97
00:03:54.740 --> 00:03:57.300
network. Competing head on with SpaceX's
98
00:03:57.300 --> 00:03:59.820
Starlink, this launch pushes the total in
99
00:03:59.820 --> 00:04:02.180
orbit past the 390 mark.
100
00:04:02.580 --> 00:04:05.300
Anna: It's also worth noting the clock is ticking.
101
00:04:05.540 --> 00:04:08.540
The FCC requires Amazon to have half that
102
00:04:08.540 --> 00:04:10.740
constellation flying by the end of this
103
00:04:10.740 --> 00:04:13.220
month. So expect the launch pace to stay
104
00:04:13.220 --> 00:04:13.700
brisk.
105
00:04:14.100 --> 00:04:16.540
Avery: Our next story is for all patriotic
106
00:04:16.540 --> 00:04:19.540
Americans. Well, sort of. With
107
00:04:19.540 --> 00:04:22.540
America's 250th birthday coming up on the
108
00:04:22.540 --> 00:04:25.420
4th of July, NASA's Chandra X Ray
109
00:04:25.420 --> 00:04:27.740
Observatory has given the country a rather
110
00:04:27.740 --> 00:04:29.060
spectacular gift.
111
00:04:29.780 --> 00:04:32.380
Anna: Four new composite images, each
112
00:04:32.380 --> 00:04:34.580
rendered in red, white and blue.
113
00:04:34.820 --> 00:04:37.380
Combining Chandra's X ray vision with light
114
00:04:37.380 --> 00:04:40.340
from Hubble Webb and ground based telescopes,
115
00:04:40.580 --> 00:04:43.540
Avery: the lineup includes the Cassiopeia, a
116
00:04:43.620 --> 00:04:45.990
supernova remnant, the star
117
00:04:46.150 --> 00:04:48.470
forming nebula NGC
118
00:04:48.710 --> 00:04:51.270
3603, the
119
00:04:51.270 --> 00:04:54.230
spiral galaxy Messier 94,
120
00:04:54.630 --> 00:04:56.350
and the galaxy cluster
121
00:04:56.350 --> 00:04:58.230
ZWCL
122
00:04:58.390 --> 00:05:00.190
0024
123
00:05:00.590 --> 00:05:03.590
1652, where Hubble
124
00:05:03.590 --> 00:05:06.310
has mapped out dark matter's fingerprints.
125
00:05:06.550 --> 00:05:09.270
Anna: And it's not just visual. Chandra's team
126
00:05:09.350 --> 00:05:11.830
also released three new sonifications,
127
00:05:12.380 --> 00:05:15.180
turning the X ray data into sound so you can
128
00:05:15.180 --> 00:05:17.820
genuinely listen to a supernova remnant.
129
00:05:18.460 --> 00:05:21.220
Avery: A lovely patriotic little reminder that the
130
00:05:21.220 --> 00:05:23.740
universe doesn't know about borders. But it
131
00:05:23.740 --> 00:05:25.660
sure looks good in the right color scheme.
132
00:05:26.380 --> 00:05:29.140
Anna: Now, a bit of a different segment. A couple
133
00:05:29.140 --> 00:05:31.740
of weeks back, a genuinely strange discovery
134
00:05:31.740 --> 00:05:34.420
came out of Yale and the Keck Observatory and
135
00:05:34.420 --> 00:05:36.580
it's stuck with us. So we wanted to circle
136
00:05:36.580 --> 00:05:38.220
back and make sure you'd heard it too.
137
00:05:39.050 --> 00:05:41.530
Avery: Back in Mid June, astronomers confirmed a
138
00:05:41.530 --> 00:05:44.170
third galaxy that appears to have essentially
139
00:05:44.330 --> 00:05:46.770
zero dark matter. It's called
140
00:05:46.770 --> 00:05:49.450
DF9. Sitting alongside two previous
141
00:05:49.450 --> 00:05:52.010
oddballs, DF2 and DF4.
142
00:05:52.570 --> 00:05:55.290
Anna: All three line up in a tight, straight
143
00:05:55.290 --> 00:05:58.050
trail of galaxies. And that alignment is the
144
00:05:58.050 --> 00:06:00.850
real kicker. It suggests they didn't form the
145
00:06:00.850 --> 00:06:03.770
normal way. Tucked inside a dark matter halo.
146
00:06:04.340 --> 00:06:07.060
Avery: The leading idea is a bullet dwarf collision,
147
00:06:07.300 --> 00:06:10.180
a violent high speed crash between galaxies
148
00:06:10.180 --> 00:06:12.620
billions of years ago that literally stripped
149
00:06:12.620 --> 00:06:15.220
the ordinary gas away from its dark matter,
150
00:06:15.460 --> 00:06:17.860
letting new galaxies form from that gas
151
00:06:17.860 --> 00:06:18.260
alone.
152
00:06:18.900 --> 00:06:21.340
Anna: Using the Keck Observatory's Cosmic Web
153
00:06:21.340 --> 00:06:24.260
Imager, the team led by Yale's Michael Keim
154
00:06:24.260 --> 00:06:26.980
measured DF9's mass by tracking how its
155
00:06:26.980 --> 00:06:29.380
stars move. And the total came out almost
156
00:06:29.460 --> 00:06:32.360
exactly matching the visible matter. No room
157
00:06:32.360 --> 00:06:34.120
left over for anything invisible.
158
00:06:34.680 --> 00:06:36.800
Avery: It's a big deal because it's some of the
159
00:06:36.800 --> 00:06:38.840
clearest evidence yet that dark matter
160
00:06:38.840 --> 00:06:41.480
behaves like an actual physical substance,
161
00:06:41.720 --> 00:06:43.960
one that can genuinely be separated from
162
00:06:43.960 --> 00:06:46.080
ordinary matter in the right violent
163
00:06:46.080 --> 00:06:46.760
circumstances.
164
00:06:47.480 --> 00:06:49.880
Anna: So if this one slipped past you when it first
165
00:06:49.880 --> 00:06:52.360
broke, now you're all caught up, and it's a
166
00:06:52.360 --> 00:06:55.280
great excuse to look up DF2, DF4 and
167
00:06:55.280 --> 00:06:56.360
DF9 together.
168
00:06:56.520 --> 00:06:59.410
Next clear night. Well, with a very big
169
00:06:59.410 --> 00:07:01.170
telescope, let's
170
00:07:01.170 --> 00:07:03.050
Avery: finish on something completely different.
171
00:07:03.610 --> 00:07:06.610
NASA administrator Jared Isaacman has made a
172
00:07:06.610 --> 00:07:08.930
promise. If the United states wins the
173
00:07:08.930 --> 00:07:11.810
2026 FIFA World Cup, NASA will
174
00:07:11.810 --> 00:07:13.610
send a soccer ball to the moon.
175
00:07:14.330 --> 00:07:17.170
Anna: This is not a joke. Apparently, Isaacman
176
00:07:17.170 --> 00:07:19.570
made the pledge alongside Carlos Garcia
177
00:07:19.570 --> 00:07:22.170
galan, who runs NASA's moon base program,
178
00:07:22.330 --> 00:07:24.730
during a briefing about lunar lander plans.
179
00:07:25.520 --> 00:07:28.480
Avery: The plan is to one up Apollo 14 astronaut
180
00:07:28.480 --> 00:07:31.440
Alan Shepard, who famously smuggled a golf
181
00:07:31.440 --> 00:07:33.880
club and a couple of balls to the moon back
182
00:07:33.880 --> 00:07:36.800
in 1971 for a very short round
183
00:07:36.800 --> 00:07:37.760
of lunar golf.
184
00:07:38.240 --> 00:07:40.920
Anna: NASA's already sent an official World cup
185
00:07:40.920 --> 00:07:43.400
ball to the space station so astronauts could
186
00:07:43.400 --> 00:07:46.040
test their zero gravity footwork. This would
187
00:07:46.040 --> 00:07:48.360
be the away leg, Garcia.
188
00:07:48.360 --> 00:07:50.400
Avery: Galan says the ball is light enough that
189
00:07:50.400 --> 00:07:52.760
finding room on a future lander payload won't
190
00:07:52.760 --> 00:07:55.190
be a problem. So really, it's all down to
191
00:07:55.190 --> 00:07:56.310
Team USA now.
192
00:07:56.870 --> 00:07:57.830
Anna: No pressure.
193
00:07:58.310 --> 00:08:00.230
Avery: And, um, that's a wrap for today's episode.
194
00:08:00.630 --> 00:08:02.710
Anna: If swift's launch finally goes ahead
195
00:08:02.710 --> 00:08:04.790
overnight, we'll bring you the result first
196
00:08:04.790 --> 00:08:07.230
thing tomorrow. Until then, clear skies,
197
00:08:07.230 --> 00:08:07.590
everyone.
198
00:08:08.230 --> 00:08:10.270
Avery: And keep an eye out for Aurora this weekend.
199
00:08:10.270 --> 00:08:11.750
You might just catch a show.
200
00:08:12.310 --> 00:08:14.550
Anna: We'll do it all again tomorrow. Bye.
201
00:08:17.990 --> 00:08:18.550
Stories,
202
00:08:21.120 --> 00:08:21.360
Love.
203
00:08:25.920 --> 00:08:27.360
Avery: Story, soul.
