00:00:01 --> 00:00:03 Anna: Picture an asteroid. You're probably
00:00:03 --> 00:00:06 imagining a potato, one lump of
00:00:06 --> 00:00:09 rock tumbling through the dark. Now
00:00:09 --> 00:00:12 imagine three lumps joined at the neck
00:00:12 --> 00:00:15 like a cosmic string of pearls and
00:00:15 --> 00:00:18 a tiny moon keeping pace alongside.
00:00:18 --> 00:00:21 Avery: That's a real object out in the main belt.
00:00:21 --> 00:00:24 And until this week, nobody knew it looked
00:00:24 --> 00:00:26 like that. We'll take you there first, and
00:00:26 --> 00:00:27 then
00:00:27 --> 00:00:30 Anna: we'll chase a wind. One that lights up
00:00:30 --> 00:00:32 our own sky and the same kind of
00:00:32 --> 00:00:35 wind that's slowly stripping a planet
00:00:35 --> 00:00:36 bare.
00:00:36 --> 00:00:39 Avery: G' day and welcome to Astronomy Daily. It's
00:00:39 --> 00:00:42 Friday 31st July, 2026.
00:00:42 --> 00:00:43 I'm Avery.
00:00:43 --> 00:00:46 Anna: And I'm Anna. Four stories today,
00:00:46 --> 00:00:48 a skywatch that spans both
00:00:48 --> 00:00:51 hemispheres and a thread running right
00:00:51 --> 00:00:54 through the back half of the show. Avery,
00:00:54 --> 00:00:55 where do we start?
00:00:55 --> 00:00:58 Avery: Where else? With the three faced asteroid.
00:00:59 --> 00:01:01 Anna: So, asteroid 44
00:01:01 --> 00:01:04 NISA. The number tells you it was one of
00:01:04 --> 00:01:07 the early finds. Discovered back in
00:01:07 --> 00:01:09 1857. One of the
00:01:09 --> 00:01:12 brightest asteroids in the whole main
00:01:12 --> 00:01:15 belt. That broad river of rubble between
00:01:15 --> 00:01:17 Mars and Jupiter. It's about
00:01:17 --> 00:01:20 75 kilometers across at its widest.
00:01:21 --> 00:01:24 So a serious chunk of rock, one of the
00:01:24 --> 00:01:26 largest of its particular type.
00:01:26 --> 00:01:29 Its type matters here. NISA is
00:01:29 --> 00:01:32 what astronomers call an E type. Its
00:01:32 --> 00:01:35 surface is rich in a pale mineral called
00:01:35 --> 00:01:38 instatite, which makes it unusually
00:01:38 --> 00:01:41 bright and reflective. There aren't many
00:01:41 --> 00:01:43 big E types, so NYSSA has always
00:01:43 --> 00:01:46 been a bit of a favorite. But its shape
00:01:46 --> 00:01:49 has been a nagging mystery for years.
00:01:49 --> 00:01:52 Earlier observations hinted it might be
00:01:52 --> 00:01:55 what's called a contact binary. Two
00:01:55 --> 00:01:58 lobes stuck together, a bit like a
00:01:58 --> 00:02:00 peanut or a snowman. We've seen
00:02:00 --> 00:02:03 plenty of those. Comet 67P
00:02:03 --> 00:02:06 that Rosetta visited, the little asteroid
00:02:06 --> 00:02:09 Dimorphos that the NASA Dart mission crashed
00:02:09 --> 00:02:12 into last year. Donald Johansen that
00:02:12 --> 00:02:15 the Lucy spacecraft flew past last year.
00:02:15 --> 00:02:17 Two lobes is almost normal.
00:02:18 --> 00:02:20 BISA isn't normal. A team
00:02:21 --> 00:02:23 led by Kate Minker at, uh, Lowell Observatory
00:02:24 --> 00:02:26 has just announced in a study with the
00:02:26 --> 00:02:29 wonderful title Unmasking 44
00:02:29 --> 00:02:32 Nysa, that Nyssa appears to have
00:02:32 --> 00:02:35 three lobes. Three joined by
00:02:35 --> 00:02:38 two narrow necks, like, uh, a figure carved
00:02:38 --> 00:02:40 with two deep waists around it.
00:02:41 --> 00:02:43 If it holds up, it's the first tri
00:02:43 --> 00:02:45 lobed asteroid ever seen.
00:02:46 --> 00:02:49 Avery: Three lobes? How do you even see that? These
00:02:49 --> 00:02:52 things are tiny dots, even in big telescopes.
00:02:52 --> 00:02:55 Anna: That's the clever part. They used two of
00:02:55 --> 00:02:58 the sharpest eyes on Earth. The Large
00:02:58 --> 00:03:00 Binocular Telescope in Arizona. Its
00:03:00 --> 00:03:03 main mirror is about eight meters, roughly
00:03:03 --> 00:03:06 three times the size of Hubble's, running an
00:03:06 --> 00:03:09 instrument called sharkvis, plus
00:03:09 --> 00:03:11 the Very Large Telescope down in Chile.
00:03:12 --> 00:03:15 And they used adaptive optics, a mirror
00:03:15 --> 00:03:17 that flexes hundreds of times a second,
00:03:18 --> 00:03:20 nearly 600 tiny actuators
00:03:20 --> 00:03:23 pushing on it to cancel out the blurring of
00:03:23 --> 00:03:26 our atmosphere in real time. The
00:03:26 --> 00:03:29 result is sharper than Hubble. They imaged
00:03:29 --> 00:03:31 NISA on two nights, 15
00:03:31 --> 00:03:34 February and 21 March this year.
00:03:35 --> 00:03:37 And both times the same strange
00:03:37 --> 00:03:39 three part silhouette turned up.
00:03:40 --> 00:03:42 Which brings us to the second surprise.
00:03:42 --> 00:03:45 NISA has a moon, a little one,
00:03:45 --> 00:03:48 about a kilometer across, orbiting at
00:03:48 --> 00:03:50 least 170 kilometers out.
00:03:51 --> 00:03:53 It's been given the placeholder name
00:03:53 --> 00:03:55 S202644
00:03:55 --> 00:03:58 1, and it
00:03:58 --> 00:04:01 was hiding in plain sight, drowned out by
00:04:01 --> 00:04:03 the glare of the much brighter asteroid next
00:04:03 --> 00:04:06 to it. To dig it out, the team borrowed a
00:04:06 --> 00:04:09 trick from a completely different corner of
00:04:10 --> 00:04:13 high contrast imaging, the same family
00:04:13 --> 00:04:15 of techniques we used to pull a faint
00:04:15 --> 00:04:18 planet out of the glare of its star.
00:04:18 --> 00:04:20 As one of the sharkvis scientists,
00:04:21 --> 00:04:23 Gianluca Lee Cauce, put it, they used
00:04:23 --> 00:04:26 that technique to catch a faint companion
00:04:26 --> 00:04:29 whose light was being swamped by the primary.
00:04:29 --> 00:04:32 And because they caught it moving across two
00:04:32 --> 00:04:35 separate observing runs, they know it's
00:04:35 --> 00:04:38 genuinely in orbit, not a background star.
00:04:38 --> 00:04:41 Avery: Photobombing the shot and a, uh, moon is
00:04:41 --> 00:04:41 useful, right?
00:04:42 --> 00:04:44 Anna: Not just a bonus, it's enormously
00:04:44 --> 00:04:47 useful. This is the thing I love about it.
00:04:47 --> 00:04:50 Watch how fast the moon goes round and how
00:04:50 --> 00:04:53 far out it sits and you can weigh the
00:04:53 --> 00:04:55 asteroid. You get nice's mass.
00:04:56 --> 00:04:58 Combine the mass with the size and you get
00:04:58 --> 00:05:01 its density. And density is the whole
00:05:01 --> 00:05:03 ball game here, because there are two
00:05:03 --> 00:05:06 competing stories for what NYSA actually
00:05:06 --> 00:05:09 is. Story one, it's a
00:05:09 --> 00:05:11 genuine three part body, maybe a
00:05:11 --> 00:05:14 contact trinary. Three chunks that
00:05:14 --> 00:05:17 drifted together and gently stuck.
00:05:18 --> 00:05:21 It's one solid, deeply dented lump
00:05:21 --> 00:05:24 that only looks three lobed from our angle.
00:05:25 --> 00:05:27 Density can help tell those apart. A loose
00:05:27 --> 00:05:30 rubble pile reads light and fluffy. A
00:05:30 --> 00:05:33 solid coherent rock reads dense.
00:05:34 --> 00:05:36 So that little moon is going to help settle
00:05:36 --> 00:05:39 what kind of world this is and how it got
00:05:39 --> 00:05:40 so weird.
00:05:40 --> 00:05:42 Avery: Any theories on the how?
00:05:42 --> 00:05:45 Anna: Nothing locked in. And that honesty is
00:05:45 --> 00:05:48 the fun of it. It could be a record of
00:05:48 --> 00:05:51 gentle slow motion collisions in the belt,
00:05:51 --> 00:05:54 bodies bumping and merging over billions of
00:05:54 --> 00:05:57 years. It could be the aftermath of a
00:05:57 --> 00:05:59 bigger smash that left a battered
00:05:59 --> 00:06:02 survivor. Or observations of that
00:06:02 --> 00:06:05 moon will narrow it down. For now, we've got
00:06:05 --> 00:06:08 a brand new kind of object, a triple
00:06:08 --> 00:06:11 lobed asteroid with its own satellite
00:06:11 --> 00:06:13 sitting in a part of the sky we thought we
00:06:13 --> 00:06:16 understood. And that's the quiet lesson of
00:06:16 --> 00:06:18 NISA. It was found in
00:06:18 --> 00:06:21 1857. It's one of the best
00:06:21 --> 00:06:24 studied bright asteroids we have. And in
00:06:24 --> 00:06:27 2026, it still had two secrets
00:06:27 --> 00:06:30 left. A shape nobody expected and a
00:06:30 --> 00:06:33 moon nobody had seen. The solar system
00:06:33 --> 00:06:34 is not done surprising
00:06:34 --> 00:06:37 Avery: us from a world we can nearly
00:06:37 --> 00:06:39 touch to one we may never reach,
00:06:40 --> 00:06:42 but might one day actually see.
00:06:43 --> 00:06:45 NASA has just backed a genuinely audacious
00:06:45 --> 00:06:48 idea. A plan to photograph the surface of a
00:06:48 --> 00:06:51 planet around another star. Not detect
00:06:51 --> 00:06:53 it, not measure it, see it.
00:06:53 --> 00:06:56 Continents, oceans, weather.
00:06:56 --> 00:06:59 Anna: Hang on, we can't do that. I feel
00:06:59 --> 00:07:01 like we have pictures of exoplanets.
00:07:02 --> 00:07:05 Avery: We have dots. Every exoplanet we've
00:07:05 --> 00:07:07 ever found is, in a sense, invisible. We
00:07:07 --> 00:07:10 infer it from a star's tiny wobble or a faint
00:07:10 --> 00:07:12 dip dip in brightness as the planet crosses
00:07:12 --> 00:07:15 in front. In the very best cases, we've
00:07:15 --> 00:07:18 captured a single pixel of light. Nobody
00:07:18 --> 00:07:20 has ever resolved a surface. The problem is
00:07:20 --> 00:07:23 brutal. A star can be around 10 billion times
00:07:23 --> 00:07:25 brighter than the little Earth sized planet
00:07:25 --> 00:07:28 beside it. And the two sit almost on top of
00:07:28 --> 00:07:31 each other in the sky. The new concept comes
00:07:31 --> 00:07:33 from physicist Paul Stankis at Brookhaven,
00:07:33 --> 00:07:36 and it's one of 18 early stage ideas NASA
00:07:36 --> 00:07:38 just funded through its innovative Advanced
00:07:38 --> 00:07:41 Concepts Program. Nyack. These are
00:07:41 --> 00:07:43 seed grants, small money, nine months,
00:07:43 --> 00:07:46 permission to chase something wild. His is
00:07:46 --> 00:07:49 called Mapping Alien Continents. It works in
00:07:49 --> 00:07:52 two moves. First, a new kind of light
00:07:52 --> 00:07:54 canceling instrument, another that blots out
00:07:54 --> 00:07:57 the star's glare while keeping the planet's
00:07:57 --> 00:07:59 light at a contrast of 10 billion to one or
00:07:59 --> 00:08:02 better. Then the really bold bit. You fly
00:08:02 --> 00:08:05 two of these on separate spacecraft about a
00:08:05 --> 00:08:07 hundred kilometers apart and combine their
00:08:07 --> 00:08:09 beams till they act as one enormous
00:08:09 --> 00:08:12 telescope, big enough in principle to resolve
00:08:12 --> 00:08:14 features on the planet's face.
00:08:14 --> 00:08:17 Anna: A telescope a hundred kilometers wide
00:08:17 --> 00:08:20 made of two spacecraft flying in formation.
00:08:20 --> 00:08:22 Avery: That's a dream. And I want to be honest about
00:08:22 --> 00:08:25 where this sits. It's a concept study, not a
00:08:25 --> 00:08:28 mission on a launch pad. It may never fly in
00:08:28 --> 00:08:30 this form, but this is exactly how the big
00:08:30 --> 00:08:33 leaps begin. Someone asks what if we could
00:08:33 --> 00:08:36 actually look? And NASA hands him a little
00:08:36 --> 00:08:37 funding to find out whether the physics
00:08:37 --> 00:08:40 holds. If it ever came together, it would
00:08:40 --> 00:08:42 turn exoplanets from statistics into
00:08:42 --> 00:08:43 places.
00:08:44 --> 00:08:45 Now, Anna, speaking of things, we can
00:08:45 --> 00:08:48 Anna: see from right here, we've got weather coming
00:08:48 --> 00:08:51 in space. Weather forecasters at
00:08:51 --> 00:08:53 noaa, uh, are tracking a couple of clouds of
00:08:53 --> 00:08:56 solar material heading our way. Coronal
00:08:56 --> 00:08:59 mass ejections, big blobs of charged
00:08:59 --> 00:09:02 gas flung off the sun. These two
00:09:02 --> 00:09:04 are faint and they're only likely to give
00:09:04 --> 00:09:07 Earth a glancing blow over the next day or
00:09:07 --> 00:09:07 so.
00:09:08 --> 00:09:09 Avery: Glancing, but not nothing.
00:09:10 --> 00:09:13 Anna: Not Nothing. Layer those CMEs
00:09:13 --> 00:09:16 on top of a fast stream already flowing from
00:09:16 --> 00:09:18 a coronal hole, a gap in the Sun's
00:09:18 --> 00:09:21 outer atmosphere, and the models suggest we
00:09:21 --> 00:09:24 could tip into a G1 storm. That's
00:09:24 --> 00:09:27 the mildest rung on the scale. No drama for
00:09:27 --> 00:09:29 the power grid, but enough to nudge the
00:09:29 --> 00:09:32 aurora to slightly lower latitudes than
00:09:32 --> 00:09:35 usual. The so over the coming nights. It's
00:09:35 --> 00:09:37 worth a look if you're up high, and I'll give
00:09:37 --> 00:09:39 you the where and when in the skywatch.
00:09:40 --> 00:09:43 Here's the thread, though. That same solar
00:09:43 --> 00:09:45 wind, the constant outflow from the sun
00:09:46 --> 00:09:48 is gentle at Earth because we've got a strong
00:09:48 --> 00:09:51 magnetic field and a thick atmosphere
00:09:51 --> 00:09:54 shrugging it off. Auroras are the pretty
00:09:54 --> 00:09:57 side of that shrug. But not every world
00:09:57 --> 00:09:59 is so lucky. Some planets have been
00:09:59 --> 00:10:02 standing in that wind for billions of years
00:10:02 --> 00:10:04 with no shield at all.
00:10:04 --> 00:10:07 Avery: Which is the perfect cue for my next 1mi
00:10:07 --> 00:10:10 escapade, a pair of NASA's craft
00:10:10 --> 00:10:12 nicknamed Blue and Gold after the University
00:10:12 --> 00:10:15 of California, Berkeley colors, built by
00:10:15 --> 00:10:17 Rocket Lab and launched last November on a
00:10:17 --> 00:10:20 blue origin. New Glenn. They're Mars bound.
00:10:20 --> 00:10:23 And right now they're loitering out near a
00:10:23 --> 00:10:25 spot called L2, about a million miles
00:10:25 --> 00:10:28 beyond Earth, waiting for the road to Mars to
00:10:28 --> 00:10:31 open. While they wait, one of them turned its
00:10:31 --> 00:10:34 cameras back toward home and snapped a family
00:10:34 --> 00:10:37 portrait. Earth and the Moon together as
00:10:37 --> 00:10:39 two slim crescents. In ordinary
00:10:39 --> 00:10:41 visible light, they look exactly as you'd
00:10:41 --> 00:10:44 hope, two bright sunlit sickles against the
00:10:44 --> 00:10:47 black. But these cameras also see in thermal
00:10:47 --> 00:10:50 infrared heat, and that view is stranger
00:10:50 --> 00:10:53 and honestly, a bit beautiful. The night
00:10:53 --> 00:10:55 side of Earth glows softly with its own
00:10:55 --> 00:10:58 warmth, while the Moon's dark half sits
00:10:58 --> 00:11:01 far, far colder. A portrait in
00:11:01 --> 00:11:03 light and a portrait in heat of the same two
00:11:03 --> 00:11:04 worlds.
00:11:04 --> 00:11:07 Anna: Gorgeous. But that's not why they built it,
00:11:07 --> 00:11:08 is it?
00:11:08 --> 00:11:10 Avery: It's not. And here's where our, uh, thread
00:11:10 --> 00:11:13 lands. Escapade exists to study exactly what
00:11:13 --> 00:11:15 we were just talking about. Its whole job,
00:11:15 --> 00:11:18 once it reaches Mars in 2027, is to measure
00:11:18 --> 00:11:20 how the solar wind strips away the Martian
00:11:20 --> 00:11:23 atmosphere. Mars doesn't have a global
00:11:23 --> 00:11:26 magnetic shield like ours, so the same wind
00:11:26 --> 00:11:28 that just gives us auroras has, over billions
00:11:28 --> 00:11:31 of years, helped peel Mars from a warmer,
00:11:31 --> 00:11:33 wetter world. The thin, cold desert we see
00:11:33 --> 00:11:36 today. Two spacecraft taking readings from
00:11:36 --> 00:11:39 two vantage points at once, watching a planet
00:11:39 --> 00:11:42 lose its air in real time. That Earth and
00:11:42 --> 00:11:44 Moon portrait was really a calibration check,
00:11:44 --> 00:11:46 a chance to point the cameras at uh, familiar
00:11:46 --> 00:11:49 targets before the main event, but it doubles
00:11:49 --> 00:11:52 as a quiet reminder. A shielded world
00:11:52 --> 00:11:55 and an unshielded one are separated by
00:11:55 --> 00:11:56 not very much at
00:11:56 --> 00:11:59 Anna: all the wind that paints our sky
00:11:59 --> 00:12:02 and the wind that scours Mars. The same
00:12:02 --> 00:12:04 sun. Lovely thread Avery
00:12:04 --> 00:12:06 right out under the sky.
00:12:07 --> 00:12:09 First the moon. We've just come off the full
00:12:09 --> 00:12:12 buck moon on the 29th, so we're in a
00:12:12 --> 00:12:15 bright waning gibbous stretch. M beautiful
00:12:15 --> 00:12:17 to look at, but that glare will wash out
00:12:17 --> 00:12:20 anything faint for the next several nights.
00:12:20 --> 00:12:23 Worth knowing before you plan meteors.
00:12:23 --> 00:12:26 The southern Delta Aquariids and the Alpha
00:12:26 --> 00:12:29 Capricornids have just passed their peak on
00:12:29 --> 00:12:32 the 30th in into the 31st. From here
00:12:32 --> 00:12:34 in the southern hemisphere, the Delta
00:12:34 --> 00:12:37 Aquarids still favor us. But with the moon
00:12:37 --> 00:12:39 this bright, keep expectations modest
00:12:39 --> 00:12:42 and watch for the occasional slow bright
00:12:42 --> 00:12:45 Capricornid fireball which both
00:12:45 --> 00:12:48 hemispheres can catch. The better news is
00:12:48 --> 00:12:50 what's coming. The Perseids build to
00:12:50 --> 00:12:53 their peak on the night of the 12th into the
00:12:53 --> 00:12:56 13th of August, and this year the Moon is
00:12:56 --> 00:12:59 nearly new, so it's a genuinely dark
00:12:59 --> 00:13:01 generous window. For North America,
00:13:01 --> 00:13:04 that's prime. Find a dark spot, look
00:13:04 --> 00:13:07 up after midnight and the northern sky can
00:13:07 --> 00:13:09 deliver a meteor a minute at its best.
00:13:10 --> 00:13:12 From the southern hemisphere, the Perseids
00:13:12 --> 00:13:15 sit low in the north so you'll see fewer.
00:13:15 --> 00:13:18 But a clear northern horizon is worth a try.
00:13:18 --> 00:13:21 Mark the 12th. Also on the 12th of
00:13:21 --> 00:13:24 August, a uh, total solar eclipse. The
00:13:24 --> 00:13:26 path of totality runs across Greenland,
00:13:26 --> 00:13:29 Iceland and a slice of Spain, with
00:13:29 --> 00:13:32 partial phases for parts of northern North
00:13:32 --> 00:13:34 America and Europe. If you're anywhere near
00:13:34 --> 00:13:37 it, never look at the partial sun without
00:13:37 --> 00:13:40 certified eclipse glasses that meet the
00:13:40 --> 00:13:41 ISO
00:13:41 --> 00:13:43
00:13:43 --> 00:13:46 standard. Ordinary sunglasses will not
00:13:46 --> 00:13:49 protect your eyes. Totality only is
00:13:49 --> 00:13:51 safe to view with the naked eye and only for
00:13:51 --> 00:13:54 those precious seconds it lasts. Planets
00:13:54 --> 00:13:57 quickly, both hemispheres. The pre dawn
00:13:57 --> 00:14:00 sky is the place to be with the brighter
00:14:00 --> 00:14:02 planets gathering low in the east before
00:14:02 --> 00:14:05 sunrise. From Sydney, look to the eastern
00:14:05 --> 00:14:08 horizon in the hour before dawn. From
00:14:08 --> 00:14:11 North America, the same window an hour or
00:14:11 --> 00:14:14 so before your local sunrise. One
00:14:14 --> 00:14:16 quick diary item and this one's for our
00:14:16 --> 00:14:19 telescope owners. On the 5th of August, a uh,
00:14:19 --> 00:14:22 dead SpaceX Falcon 9 upper stage
00:14:22 --> 00:14:24 space junk we tracked since it launched
00:14:24 --> 00:14:27 Firefly's Blue Ghost lander back in January
00:14:27 --> 00:14:30 of last year is expected to smack
00:14:30 --> 00:14:33 into the moon near Einstein Crater at
00:14:33 --> 00:14:36 about half past six Universal Time.
00:14:36 --> 00:14:39 For North America, that's the small hours of
00:14:39 --> 00:14:42 the 5th and you're the best placed to try for
00:14:42 --> 00:14:44 it. Aim for the faint dust plume near the
00:14:44 --> 00:14:47 Moon's eastern edge. Not a naked eye
00:14:47 --> 00:14:50 flash. You'll want a decent telescope from
00:14:50 --> 00:14:53 Sydney. The Moon isn't up at impact, so down
00:14:53 --> 00:14:56 here we'll be leaning on the afterimages from
00:14:56 --> 00:14:59 orbiters like NASA's Lunar Reconnaissance
00:14:59 --> 00:15:01 Orbiter. And to close our thread, the
00:15:01 --> 00:15:04 aurora. If those solar storms land
00:15:04 --> 00:15:07 as forecast, watch the high latitudes over
00:15:07 --> 00:15:10 the coming nights across the northern tier of
00:15:10 --> 00:15:13 the United States and up into Canada in the
00:15:13 --> 00:15:15 north and down towards Tasmania,
00:15:15 --> 00:15:18 southern New Zealand and southern Victoria in
00:15:18 --> 00:15:21 the south. Same sun, same wind,
00:15:21 --> 00:15:23 both ends of the Earth. And if you catch a
00:15:23 --> 00:15:26 glow, you'll know exactly what you're looking
00:15:26 --> 00:15:26 at.
00:15:26 --> 00:15:29 Avery: Everything we talked about today, the links,
00:15:29 --> 00:15:31 the images of NISA and that Earth and moon
00:15:31 --> 00:15:32 portrait is at
00:15:32 --> 00:15:35 astronomydaily.IO, along with the
00:15:35 --> 00:15:38 daily newsfeed and the newsletter signup.
00:15:38 --> 00:15:40 Anna: And if you spotted an aurora or bagged a
00:15:40 --> 00:15:43 Perseid, tell us. There's a listener contact
00:15:43 --> 00:15:45 form on the site. And we love hearing what
00:15:45 --> 00:15:46 you've seen.
00:15:46 --> 00:15:49 Avery: That's Astronomy daily for Friday 31st
00:15:49 --> 00:15:51 July. I'm Avery.
00:15:51 --> 00:15:53 Anna: And I'm Anna. Until next time. Click. Clear
00:15:53 --> 00:15:54 Skies.
