From Rocket Ruins to Cosmic Discoveries: Blue Origin's Resilience and New Magnetic Insights

0:00 Anna: Last week, a rocket exploded on its launch

0:02 pad in Cape Canaveral. The fireball could be

0:05 seen from miles. This week, the CEO

0:08 of Blue Origin looked at the wreckage and

0:10 said, five, we will fly again

0:13 this year. That story, plus magnetic

0:16 fields discovered on distant worlds. A, uh,

0:19 space telescope moments from launch, and

0:21 the definitive answer to one of astronomy's

0:24 oldest questions. This is

0:26 Astronomy Daily.

0:28 Avery: Hello and welcome to Astronomy Daily, your

0:31 daily guide to the universe and everything in

0:33 it. I'm Avery.

0:34 Anna: And I'm Anna. It is Wednesday the 4th of

0:37 June, 2026, and we have an

0:40 exceptional episode lined up.

0:41 Avery: Today we do six stories

0:44 ranging from a dramatic comeback story in the

0:46 world of commercial spaceflight to a

0:48 scientific first that reshapes what we know

0:51 about planets beyond our solar system.

0:54 If you've been listening this week, you'll

0:55 know Blue Origin had a very bad Thursday.

0:58 We'll have a full update on what comes next,

1:00 but let's get into it.

1:02 Anna: Last Thursday night at Cape Canaveral, Blue

1:04 Origin's New Glenn rocket exploded on its

1:07 launch pad during a routine pre launch hot

1:10 fire test. The fireball engulfed Launch

1:13 Complex 36. Debris was found up

1:15 to half a mile away. It was the biggest and

1:18 most public failure in the company's history,

1:21 and many observers feared the road back could

1:24 take years.

1:25 Avery: But as of this week, Blue Origin CEO

1:28 Dave Limp is pushing back hard on that

1:30 narrative. He's saying the damage is far less

1:33 catastrophic than it looked.

1:35 Anna: Limp posted a, uh, detailed update on X in

1:38 which he said that now that teams have gained

1:40 full access to the pad, there's actually some

1:43 good news. The propellant storage

1:44 infrastructure, the oxygen tanks, the liquid

1:47 hydrogen storage, and the cryogenic methane

1:50 tanks all came through the blast in good

1:52 shape. He called that extremely fortunate

1:55 because those are very long lead items to

1:58 replace.

1:59 Avery: The water tower also survived. The main

2:01 support gantry is damaged, but crucially,

2:04 Limp says it can be repaired in place. It

2:07 doesn't need to be torn down and rebuilt from

2:09 scratch.

2:10 Anna: Perhaps most importantly, there are spare

2:12 assets. The previously flown New Glenn

2:15 Booster, nicknamed Never Tell Me the Odds,

2:18 along with three upper stages stored in a

2:20 neighboring integration facility, all appear

2:23 undamaged.

2:24 Avery: As for the cause of the explosion, there's

2:26 still no official word. The test was not

2:29 within the scope of FAA license activities,

2:31 so the FAA won't be leading the

2:33 investigation. Blue Origin is conducting its

2:36 own assessment.

2:37 Anna: Limp also used the moment to announce a

2:39 strategic pivot the company had already been

2:42 working on, eliminating the need for a

2:44 transporter erector, the massive structure

2:47 used to move and stand the rocket upright. He

2:50 said Blue Origin will now skip straight to an

2:53 alternative vertical launch concept, which

2:55 means they don't need to build a replacement

2:57 for the one destroyed during the explosion.

3:00 Avery: And he closed his statement with Blue

3:02 Origin's motto, gradatum ferociter,

3:05 which means step by step,

3:07 ferociously, and the declaration we

3:10 will fly again before the end of this year.

3:12 Anna: That's an aggressive timeline by any measure,

3:15 but it's the kind of defiant pledge

3:17 investors, customers and the broader space

3:20 industry needed to hear. Patrick Space Force

3:23 Base has cleared Blue Origin to begin its

3:25 full damage assessment of Launch Complex 36,

3:28 though the formal rebuilding process is now

3:31 underway.

3:32 Avery: We will of course, keep tracking this story

3:34 as it develops.

3:35 Anna: Now let's move from the dramatic to the

3:38 extraordinary. Scientists have just published

3:41 what they're calling the first direct

3:43 evidence that planets beyond our solar system

3:46 possess magnetic fields. And they found it

3:48 by studying the wind.

3:50 Avery: This is a remarkable piece of science. A team

3:53 of astronomers used two of the world's most

3:55 powerful ground based telescopes, the ESO's

3:58 Very Large Telescope in Chile and the Gemini

4:01 North Telescope in Hawaii, to measure wind

4:03 speeds on seven so called hot Jupiter

4:05 exoplanets.

4:07 Anna: Hot Jupiters are gas giants roughly the

4:10 size of Jupiter but orbiting extremely

4:13 close to their host stars, far closer than

4:15 Mercury is to our sun because they're

4:18 tidally locked, always showing the same face

4:21 to their star. One side is perpetually

4:24 scorching hot and the other is freezing

4:26 cold. That temperature difference creates

4:29 powerful winds that howl from the day side to

4:32 the night side.

4:33 Avery: The researchers measured those wind speeds

4:36 and found something totally counterintuitive.

4:39 On the hotter planets, the winds were

4:41 actually slower, and that is the opposite of

4:43 what standard physics would predict.

4:45 Anna: If you have more thermal energy, you'd expect

4:48 stronger winds. But these planets are pumping

4:51 the brakes. And the best explanation, the one

4:54 that actually fits the data, is magnetic

4:57 fields.

4:58 Avery: A magnetic field can interact with the

5:00 electrically charged gas in a planet's upper

5:02 atmosphere and slow those winds down. The

5:05 stronger the magnetic field, the greater the

5:07 braking effect. The team inferred magnetic

5:10 field strengths ranging up to four times that

5:13 of Saturn and up to about half the strength

5:16 of Jupiter's field.

5:17 Anna: The wind speeds themselves were

5:19 extraordinary. They ranged from around

5:22 7,000 km per hour up to more

5:25 than 25,000 km per hour.

5:28 For context, the fastest winds measured on

5:30 Jupiter reach about 1,500

5:33 kilometers per hour. These are winds on a

5:36 scale we simply don't see in our own solar

5:38 system.

5:39 Avery: The results were published in the journal

5:41 nature astronomy on June 2, and the

5:44 implications go well beyond just knowing that

5:46 Other planets have magnetic fields. Magnetic

5:49 fields are thought to play a critical role in

5:51 protecting planetary atmospheres from being

5:53 stripped away by stellar radiation, which is

5:56 one of the key factors in whether a planet

5:58 could over billions of years, be potentially

6:01 remain habitable.

6:03 Anna: As the lead researcher put it, this is a key

6:05 step toward ultimately understanding which

6:08 planets can stay alive, keep their water,

6:11 and perhaps even one day host life

6:14 as we know it.

6:15 Avery: A genuinely landmark result.

6:18 Anna: Our next story takes us to NASA's Goddard

6:21 Space Flight center in Greenbelt, Maryland,

6:23 where engineers have completed what they

6:25 describe as the last look humanity

6:28 will ever take on a critical piece of

6:31 hardware before it becomes the eyes of

6:33 humanity on the universe.

6:35 Avery: We're talking about the Nancy Grace Roman

6:38 Space Telescope and specifically its primary

6:41 mirror, a 2.4 meter

6:45 reflector that will be the heart of the

6:47 instrument once it launches into space.

6:49 Anna: On May 20th and 21st,

6:52 engineers performed a meticulous final

6:54 inspection. They tilted the entire

6:57 observatory onto its side, deployed the

7:00 protective hood that will be stowed during

7:02 launch, and used a high resolution camera

7:05 with a powerful zoom lens to do a thorough

7:08 multipurpose check, looking for any particles

7:10 that may have settled on the mirror surface

7:13 during testing and confirming that the

7:15 optical alignment hadn't

7:16 Avery: shifted it pass with flying colors.

7:20 No specs, no misalignment. The

7:22 mirror's silver coating, which is just

7:24 400nm thick, hundreds

7:27 of times thinner than a human hair, is

7:29 perfect.

7:31 Anna: The Roman telescope manager at Goddard, J.

7:34 Scott Smith, marked the moment beautifully.

7:37 He said the Roman engineering team laid

7:39 eyes on the telescope for the final time

7:42 before it in turn becomes the eyes of

7:45 humanity, revealing the wonders of the

7:47 cosmos. That's a sentence worth sitting with.

7:51 Avery: With this milestone complete, Roman will now

7:53 be shipped to Kennedy Space center in Florida

7:56 in preparation for its planned launch,

7:58 currently scheduled for as early as, ah,

8:00 September 2026.

8:02 Anna: Once in space, Roman will travel to the sun,

8:04 earth, Lagrange point 2, known as

8:07 L2, the same orbital neighborhood where the

8:10 James Webb Space Telescope operates. It will

8:13 join the most exclusive telescope real estate

8:15 in the solar system.

8:17 Avery: And Roman's scientific ambitions are

8:19 extraordinary. It will have a field of view

8:22 at least 100 times larger than the Hubble

8:24 Space Telescope, potentially measuring light

8:27 from a billion galaxies over its lifetime.

8:30 It will also be capable of directly imaging

8:32 exoplanets by blocking out starlight

8:35 and conducting a comprehensive statistical

8:37 census of planetary systems across our

8:40 galaxy.

8:41 Anna: We are getting very close to launch.

8:43 September can't come soon enough.

8:45 Avery: We'll be right back after this short break

8:47 for a word from our sponsors.

8:48 Anna: Stay with us and we're back three more

8:51 stories to go and they are all fascinating.

8:54 Avery: Space Force Has Made a Very large Investment

8:57 in SpaceX On May 29, the US

9:00 Space Force announced it had awarded Elon

9:02 Musk's company a $4.16

9:05 billion contract for a program called the

9:08 Space Based Airborne Moving Target

9:10 Indicator, or SBAMTI M.

9:13 Anna: In plain language, the goal is to build a

9:15 constellation of satellites that can track

9:17 and target airborne threats from orbit,

9:20 things like aircraft, cruise missiles and

9:22 other fast moving threats anywhere on Earth

9:25 at any time.

9:26 Avery: The satellites are designed to fill a gap

9:28 that currently exists in military

9:30 surveillance. Traditionally, the US

9:32 Military uses aircraft, particularly AWOKS

9:35 planes, to track airborne targets. But

9:38 satellites can reach areas where it's too

9:40 dangerous to fly and they can maintain

9:42 persistent coverage that aircraft simply

9:45 can't match.

9:46 Anna: The contract is part of the Trump

9:47 administration's broader Golden Dome Missile

9:50 Defense Initiative, which aims to build a

9:52 layered national defense system including

9:54 ground based interceptors, enhanced radar

9:57 networks, and now this space based tracking

10:00 layer.

10:00 Avery: SpaceX isn't the only company involved. Space

10:03 Force confirmed there are nine companies in

10:05 the SBA MTI vendor pool, though the

10:08 identities of the other eight have not been

10:10 made public for national security reasons.

10:13 More contracts are expected to be issued over

10:15 the coming year.

10:16 Anna: The goal is to have an initial operational

10:18 constellation of these satellites in place by

10:21 2028. This contract was also

10:24 accompanied by a separate $2.29

10:26 billion Space Force award to SpaceX

10:29 earlier in the week for a Space Data Network

10:32 backbone, a secure high speed military

10:35 communication system.

10:36 Avery: In total, SpaceX received over six and a half

10:39 billion dollars in Space Force contracts in a

10:42 single week. For a company that is also

10:44 preparing for what could be the largest IPO

10:46 in stock market history, it's been quite a

10:49 week in Hawthorne, California.

10:51 Anna: Now an update about a visitor that has

10:53 already left, but whose influence is still

10:55 being felt across the astronomy community.

10:58 Avery: 3i ATLAS, the third

11:00 interstellar object ever confirmed to pass

11:03 through our solar system. Discovered on July

11:06 1, 2025 by the Atlas Telescope Network in

11:09 Chile, it is now heading back out into the

11:11 deep Galaxy, never to return.

11:13 Anna: But the scientific conversation it sparked is

11:16 very much alive. A new analysis published

11:19 this week explores the way that 3i

11:21 atlas has prompted astronomers to

11:24 fundamentally update what they understand

11:26 not just about foreign solar systems, but

11:29 about our own.

11:30 Avery: Let's do a quick recap for listeners who may

11:32 have joined us since the main 3i Atlas

11:35 coverage last year. This was an extraordinary

11:38 object. It was only the third interstellar

11:40 visitor ever confirmed after 1i

11:43 Oumuamua, um, in 2017 and

11:46 2i Borisov in 2019.

11:49 But unlike those, 2 3i Atlas

11:51 was clearly an active comet, releasing dust

11:54 and gas with multiple tails and a nucleus

11:57 estimated at somewhere between a few hundred

11:59 meters and several kilometers across.

12:02 Anna: It passed closest to the sun in late October

12:05 2025, then flew by Mars, then

12:08 Jupiter, in March 2026, and is now

12:10 departing. But even as it fades, the data it

12:13 generated continues to be analyzed.

12:16 Avery: One of the most striking findings came from a

12:18 University of Michigan study that examined

12:20 the water ice in 3i atlas

12:23 and found it contained an extraordinarily

12:26 high concentration of deuterium heavy

12:28 isotope of hydrogen that is far less common

12:31 in comets from our own solar system.

12:33 Anna: That suggests three I ATLAS

12:36 formed in an environment that was

12:38 dramatically colder and more isolated than

12:40 the conditions that shaped our solar system's

12:43 comets. Researchers have since traced its

12:46 likely origin to a cold, dark corner of the

12:49 Milky Way that had not yet fully assembled

12:51 into a planetary system when this object

12:54 formed, potentially making it up to 11

12:57 billion years old, more than twice the age of

13:00 our Sun.

13:01 Avery: What does all of this teach us? Quite a lot,

13:03 as it turns out. It tells us that the

13:05 chemical signatures of comets vary

13:07 dramatically across the galaxy, meaning the

13:10 building blocks of planetary systems,

13:12 including the water and organics that may

13:15 seed life differ significantly from one

13:17 stellar neighborhood to another.

13:19 Anna: It also demonstrates how much we can learn

13:22 from fleeting cosmic visitors, and if we have

13:24 the tools to observe them quickly. The

13:27 Veracruz Rubin Observatory in Chile, which

13:30 released its first images in June, is

13:32 expected to dramatically increase the rate at

13:35 which we detect future interstellar objects,

13:37 which could let astronomers determine whether

13:40 three I Atlas unusual

13:42 properties are rare or commonplace.

13:45 Avery: A visitor that has left the building but

13:47 whose lessons will be with us for years to

13:50 come.

13:50 Anna: Our final story today answers a question that

13:53 astrophysicists have been wrestling with for

13:56 at what exact mass does a neutron star

13:59 collapse into a black hole?

14:01 Avery: This is one of those wonderfully fundamental

14:03 questions in physics. We know that when a

14:05 massive star dies, it can leave behind either

14:08 a neutron star or a black hole, depending on

14:11 how massive the original star was. But the

14:13 precise boundary between those two fates has

14:16 never been defeated definitively pinned down

14:19 until now.

14:20 Anna: Researchers at the Hun Ren Wigner Research

14:23 center for Physics in Hungary have published

14:25 what they describe as a definitive answer.

14:28 The boundary falls between 2.2 and

14:31 2.3 solar masses.

14:33 Avery: To unpack that a neutron star is one of

14:36 the most extreme objects in the universe,

14:38 imagine taking the mass of two suns and

14:41 compressing it into a sphere about the size

14:44 of a city. A teaspoon of its material would

14:47 weigh billions of tons. These are

14:49 objects so dense that the neutrons themselves

14:52 are packed together like one giant atomic

14:55 nucleus.

14:56 Anna: But there's a limit to how much mass a

14:58 neutron star can hold before gravity wins

15:01 and the whole thing collapses inward to form

15:03 a black hole. That limit, the Tolman,

15:06 Oppenheimer, Volkov limit, has previously

15:09 been estimated to be somewhere between two

15:11 and three solar masses. Depending on the

15:14 assumptions used, this new

15:16 Avery: work narrows that window considerably,

15:18 placing the critical threshold between 2.2

15:21 and 2.3 solar masses.

15:24 Beyond that, a neutron star simply cannot

15:27 support itself against gravity, and the black

15:29 hole is born.

15:30 Anna: Why does this matter? Because it gives

15:32 astronomers a clearer tool to classify

15:35 compact objects they observe. When we detect

15:38 something via, uh, gravitational waves or X

15:40 ray observations, knowing the precise mass

15:43 boundary between neutron stars and black

15:45 holes helps us identify what we're actually

15:48 looking at.

15:49 Avery: It also feeds into our understanding of what

15:51 happens in neutron star m mergers, the

15:54 cataclysmic collisions that produce

15:56 gravitational wave signals, and some of the

15:58 most energetic explosions in the universe.

16:01 Anna: A beautifully precise answer to one of the

16:03 universe's most extreme questions.

16:06 Avery: Before we go, a quick look at the June sky

16:09 for our listeners in Australia, New Zealand,

16:11 and across the Southern hemisphere.

16:13 Anna: June is a wonderful month for southern

16:15 observers. We're heading toward the winter

16:17 solstice on June 21, which means longer

16:20 nights, prime time for stargazing.

16:23 Jupiter and Venus are currently visible in

16:26 the western sky after sunset, and on June

16:29 9, they'll appear at their closest to each

16:31 other, a spectacular conjunction worth

16:34 getting outside for.

16:35 Avery: The Milky Way core is also rising in the

16:38 evening sky from the Southern hemisphere

16:40 right now, beautifully positioned for

16:42 photography and naked eye observation in dark

16:44 sky locations away from city lights.

16:47 Anna: That is all from us for today. Six stories,

16:50 and every one of them a reminder that the

16:52 universe is never standing still.

16:55 Avery: From blue origin's defiant pledge to rise

16:58 from the ashes to magnetic fields discovered

17:00 on distant worlds, it has been a remarkable

17:03 day to cover space.
