Artemis Delays, Blue Origin's Lunar Pivot, and Life's Building Blocks in Space

Anna: Welcome to Astronomy Daily, your source for

the latest space and astronomy news. I'm

Anna.

Avery: And I'm Avery. Thanks for joining us on this

Saturday, January 31, 2026.

Anna: We've got a fascinating lineup today covering

everything from NASA's Artemis programme

updates to groundbreaking discoveries in the

search for life beyond Earth. Avery, what's

on the agenda?

Avery: Well, Anna, uh, we're kicking things off with

some news from NASA's Artemis 2 mission.

There's been a delay in critical testing due

to some unexpected weather challeng. Then

we'll dive into Blue Origin's strategic shift

as they pause their space tourism programme

for at least two years.

Anna: After that, we're looking up at some truly

cosmic million mile per

hour winds racing through colliding galaxies

and a mysterious object sending powerful

signals across space that has astronomers

scratching their heads.

Avery: We'll also explore some surprising findings

about Tatooine style planets orbiting

binary stars. And wrap up with an exciting

discovery. Scientists have detected a

molecule critical to life in interstellar

space for the very first time.

Anna: Quite the journey today. Let's get started.

Avery: Ready when you are.

Anna: Alright, Avery, let's start with NASA's

Artemis programme. I understand old man

Winter has thrown a wrench into their testing

schedule.

Avery: He certainly has, Anna. Uh, NASA has been

forced to delay a critical fueling test for

the Artemis 2 mission due to below freezing

temperatures at Kennedy Space Centre in

Florida. The wet dress rehearsal was

originally scheduled for January 27,

but those unexpected cold temperatures put it

on ice, so to speak.

Anna: I see what you did there. But seriously, what

exactly is this wet dress rehearsal and why

is it so important?

Avery: Great question. The wet dress rehearsal is

essentially a full practise run of launch day

procedures minus the actual launch. The team

loads the massive Space Launch System rocket

with over 700,000 gallons of super

cold liquid hydrogen and liquid oxygen.

Oxygen propellants runs through all the

countdown procedures and then drains

everything back out. It's the ultimate dress

rehearsal before the real show.

Anna: So they're basically making sure all the

plumbing works and everyone knows their roles

when the clock is ticking down. What happened

with the weather that caused the delay?

Avery: Well, Florida experienced some unusually cold

conditions. We're talking about freezing

temperatures that persisted for several days.

The problem is that loading these cryogenic

propellants in freezing conditions creates

additional safety risks and potential

technical issues. NASA's priority is always

safety first. So they made the call to

postpone.

Anna: Smart move. When are they planning to try

again?

Avery: The Space Launch System is now set to roll

out to launch pad 39B on February

5, with the wet dress rehearsal rescheduled

for February 8, this means the Artemis 2

launch is now no earlier than April 2026,

which is a shift from the previous March

target.

Anna: For our listeners who might not be following

every detail of Artemis, remind us what makes

Artemis 2.

Avery: Hannah? Artemis 2 is absolutely

historic. This will be the first crewed

mission beyond low Earth orbit in over 50

years. Basically, since the Apollo programme

ended. Four astronauts will fly around the

moon, testing all the systems and procedures

that will eventually support landing

astronauts back on the lunar surface during

Artemis 3.

Anna: It's wild to think we haven't sent humans

beyond Earth orbit in five decades.

Who's on the crew?

Avery: The crew includes NASA astronauts Reid

Wiseman, Victor Glover and Christina Koch,

along with Canadian Space Agency astronaut

Jeremy Hansen. Victor Glover will make

history as the first person of colour to

travel beyond low Earth orbit. And Christina

Koch will become the first woman to do so.

Anna: That's incredible. Even with this delay,

April 2026 is right around the corner. The

wait is almost over.

Avery: Absolutely. And honestly, a few weeks delay

to ensure everything is perfect is well worth

it when you're pioneering the return of human

deep space exploration.

Anna: Speaking of human spaceflight, let's shift

gears to Blue Origin. They're making some

significant changes to their programme,

aren't they, Avery?

Avery: They sure are, Anna. Blue Origin has

announced they're hitting pause on their New

Shepard space tourism flights for at least

two years. This is a major strategic shift

as they refocus their resources on NASA's

Artemis programme and the development of

their lunar lander.

Anna: Two years is a substantial pause.

What's driving this decision?

Avery: It all comes down to their Blue Moon lunar

lander programme. Blue Origin won a contract

from NASA worth potentially up to $3.6

billion to develop a human landing system for

the Artemis missions. They're planning an

uncrewed demonstration mission to the moon in

2028, and that's requiring a

massive concentration of their engineering

talent and resources.

Anna: So they're essentially choosing moon landings

over suborbital tourism flights. That seems

like a pretty clear indication of where they

see the bigger opportunity.

Avery: Exactly. And it's worth noting that Blue

Origin has already conducted eight successful

New Shepard tourism flights since July

2021, carrying 43 people

past the Karman Line, the internationally

recognised boundary of space at 100

kilometres altitude. So they've proven the

concept and the technology.

Anna: I remember the excitement around those early

flights. What exactly will passengers

experience on a New Shepard flight?

Avery: It's a roughly 11 minute journey where

passengers experience about three minutes of

weightlessness at the top of the arc. The

capsule has massive windows, the largest ever

flown in space, giving spectacular views of

Earth's curvature and the blackness of space.

It's suborbital, meaning you go up and come

right back down, but you definitely cross

into space.

Anna: And this pause is specifically for the

tourism programme. What about other New

Shepard missions?

Avery: Good distinction, Anna. New, uh, Shepard will

continue flying cargo and research missions.

Blue Origin has committed to conducting at

least two cargo flights each year during this

tourism pause. These missions carry

scientific experiments and payloads for

various customers, including NASA.

Anna: What about their ticket sales? I imagine

people have already paid for future flights.

Avery: Yes, and Blue Origin says they'll be

contacting customers who've already purchased

tickets to discuss their options. They

haven't specified how many people are

affected, but they've emphasised this is a

temporary pause, not an end to the programme.

Anna: It's interesting timing, isn't it? Just as

several companies are getting into the space

tourism business, Blue Origin is stepping

back, at least temporarily.

Avery: It really shows you the scale of the lunar

lander challenge. Building a spacecraft that

can safely land humans on the moon and return

them to lunar orbit is orders of magnitude

more complex than a suborbital tourism op.

Blue Origin is betting their future on, um,

being a key player in the new era of space

exploration.

Anna: And with that NASA contract potentially worth

$3.6 billion, it's not

hard to see why they're prioritising it.

Avery: Exactly. This is Blue Origin's moonshot, both

literally and figuratively. If they can

deliver a successful lunar lander, it

positions them as a major player in the new

era of space exploration.

Anna: From human space exploration to cosmic

phenomena.

Let's talk about something happening on a

scale that's almost impossible to comprehend.

Avery, tell us about these million mile per

hour winds racing through space.

Avery: Anna. Uh, this is absolutely mind blowing.

Astronomers have discovered cosmic winds

travelling at over 1.1 million miles per

hour. That's roughly 500 kilometres per

second, racing through what they're calling a

magnetic superhighway between two colliding

galaxies.

Anna: A magnetic superhighway in space?

That sounds like something out of science

fiction. Where is this happening?

Avery: This incredible phenomenon is occurring in

a system called

IC1623, which is

actually two galaxies in the process of

merging together. Located about

275 million light years

from Earth in the constellation Cetus,

these galaxies are in the late stages of a

cosmic collision and it's creating some

extraordinary physics.

Anna: Walk us through what's actually happening

here. How do galaxies colliding create these

super fast winds.

Avery: When galaxies merge, their gravitational

interactions trigger massive bursts of star

formation. We're talking thousands of stars

being born. These newborn stars live

fast and die young, creating powerful

stellar winds and supernova explosions. All

of this activity generates enormous amounts

of energy that drives material outward at

incredible speeds.

Anna: And the magnetic superhighway, what

role does that play?

Avery: Here's where it gets really fascinating. The

team from the University of Hertfordshire

discovered that magnetic fields are actually

channelling these winds, creating what they

call a superhighway that connects the two

galactic cores. Think of it like a

cosmic interstate highway system. But instead

of cars, you've got superheated gas

screaming along at speeds that make Earth's

fastest spacecraft look like they're standing

still.

Anna: That's an amazing image. How did they

detect something like this?

Avery: They used the Atacama Large Millimetre Array,

ALMA in Chile, which is specifically designed

to observe cold gas and dust in the universe.

What they found was unexpected. The magnetic

field structure doesn't just randomly radiate

outward like many galactic winds do.

Instead, it's highly organised, creating

this directed pathway between the galactic

centres.

Anna: Why is this discovery so significant? What

does it tell us about galaxy evolution?

Avery: This is crucial for understanding how

galaxies grow and evolve. These powerful

outflows, what astronomers call feedback,

can actually regulate star formation by

expelling the gas and dust that would

otherwise collapse to form new stars.

It's like a pressure release valve for

galaxies. Too much star formation can blow

away the material needed to make more stars,

which can eventually slow down or even halt

a, uh, galaxy's growth.

Anna: So galaxies regulate their own growth through

these winds. That's a pretty elegant self

limiting system.

Avery: It really is. And what makes

IC1623 particularly interesting

is that we're seeing this process in action

during a, uh, galaxy merger. When

galaxies collide, we see the most extreme

versions of these processes. The most intense

star formation, the most powerful winds,

the strongest magnetic fields. It's like

watching galaxy evolution and fast forward.

Anna: What do we think the fate of

IC1623 will be?

Avery: Eventually, these two galaxies will

completely merge into a single larger

galaxy. The current burst of star formation

will eventually exhaust much of the available

gas. And what we're looking at now, this

spectacular phase of cosmic winds and

magnetic highways will fade. But the

combined galaxy will carry the imprint of

this violent event in its structure and

stellar populations for billions of years to

come.

Anna: It's humbling to think that we're witnessing

something that takes millions of years to

play out. Just captured in a snapshot.

Avery: Absolutely. And every time we point our

telescopes at merging galaxies, we learn

something new about the forces shaping the

universe's largest structures.

Anna: Speaking of pointing our telescopes at the

universe and finding surprises, Avery, we

need to talk about this mysterious object

that's been sending powerful signals across

the galaxy. The headline says it's

unlike anything we have seen before.

Avery: That's not just hype, Anna. Astronomers have

discovered something truly a

cosmic object that's periodically sending out

intense radio signals, and it doesn't

fit into any category of known astronomical

phenomena. It's one of those discoveries that

makes you rethink what you thought you knew.

Anna: Okay, you've got my attention.

What exactly are we dealing with here?

Avery: The object sends out extremely bright

radio pulses that last about 30 to

300 seconds. That's up to five minutes

per pulse. And these pulses occur roughly

every 2.9 hours with remarkable

regularity. What makes this so unusual is

the combination of that long period and the

duration of the pulses themselves.

Anna: When you say it doesn't fit known categories.

What are the usual suspects for objects that

send out regular signals like this?

Avery: Great question. The two most common sources

of periodic radio signals are pulsars

and magnetars. Pulsars are

rapidly spinning neutron stars that sweep

beams of radiation across space like a, uh,

cosmic lighthouse. But they typically pulse

on the order of milliseconds to seconds,

not hours. And their individual pulses are

brief, usually milliseconds, not minutes.

Anna: So this object is pulsing way too slowly to

be a normal pulsar.

Avery: Exactly. And the pulses last far too

long. Magnetars, which are neutron

stars with incredibly powerful magnetic

fields, can sometimes produce longer period

signals than regular pulsars. But even they

don't typically operate on a three hour cycle

with multi minute pulse durations.

Anna: Have astronomers proposed any theories about

what this could be?

Avery: There are a few possibilities being

investigated. One idea is that it could be a

white dwarf in a binary system, which is two

stars orbiting each other, where one is a

white dwarf remnant. The interaction between

the two stars can potentially generate these

periodic radio emissions. Another possibility

is that we're seeing some kind of unusual

magnetar or pulsar that operates

differently than the ones we studied before.

Anna: When was this object discovered and how?

Avery: The discovery was made using radio telescope

observations. And what's particularly

intriguing is that the signals are powerful

enough to be detected across vast distances.

The exact distance to this object is still

being determined, but the fact that we can

detect such clear periodic signals

suggests it's either relatively close in

cosmic terms or it's Putting out tremendous

amounts of energy.

Anna: This reminds me of those fast radio bursts

we've heard about. Brief, intense radio

signals from across the universe. Is this

related?

Avery: That's a natural comparison, Anna. Um, but

fast radio bursts FRBs are different.

They're much briefer, Typically lasting

milliseconds. Though some do repeat.

This object's behaviour is more periodic and

predictable, with much longer pulse

durations. It's almost like comparing a

strobe light to a slowly rotating

searchlight.

Anna: What's the next step for studying this

mysterious object?

Avery: Astronomers will be conducting follow up

observations across multiple wavelengths. Not

just radio, but also optical X ray and

potentially others. They want to determine

exactly where it is, Measure its properties

in detail, and hopefully identify what type

of object it is. Sometimes you need multiple

types of observations to build a complete

picture.

Anna: Do discoveries like this happen often where

we find something that just doesn't fit our

existing models?

Avery: More often than you might think. Actually,

the universe keeps surprising us. Every

major improvement in our observing technology

reveals new phenomena we didn't predict.

Radio astronomy in particular has a history

of unexpected discoveries. Pulsars

themselves were a complete surprise when they

were first detected in 1967.

Anna: Could this turn out to be a whole new class

of astronomical objects?

Avery: That's definitely possible. If follow up

observations confirm that this truly doesn't

fit into any existing category, it could

indeed represent something new. Of course, it

might also turn out to be an extreme example

of a known type of object just operating in a

regime we haven't observed before. Either

way, it's expanding our understanding of

what's possible in the universe.

Anna: I love that we're still finding things that

make astronomers say we've never seen

anything like this before.

Avery: Me too, Anna. Um, it reminds us how much we

still have to learn about the cosmos.

Anna: Sticking with unexpected discoveries, let's

talk about planets that orbit two suns.

Tatooine style worlds. Avery. I understand

these aren't as rare as scientists once

thought.

Avery: That's right, Anna. Uh, new research is

challenging our assumptions about

circumbinary planets. That's the technical

term for planets that orbit both stars in a

binary system. It turns out these Star

wars style worlds might be more common than

we previously believed, Especially around

certain types of binary stars.

Anna: Before we dive into the findings, let's set

the stage.

How common are binary star systems in the

first place?

Avery: Binary systems are actually incredibly

common, Anna. Uh, roughly half of all sun

like stars exist in binary or multiple

star systems. So we're not talking about a

rare cosmic curiosity here. Binaries

are a fundamental component of the galaxy's

stellar population.

Anna: And we have discovered actual circumbinary

planets already. Right. This isn't just

theoretical.

Avery: Absolutely. NASA's Kepler Space

Telescope discovered the first confirmed

circumbinary planets back in 2011,

and we've found several more since then.

These are real worlds orbiting two suns,

just like Luke Skywalker's home planet. But

the question has always been, how common are

they?

Anna: So what does this new research tell us?

Avery: The study found that circumbinary planets

appear to be particularly common around what

are called equal mass binaries, systems

where both stars are roughly the same size

and mass. In these systems, the stable

orbital zone where planets can form and

survive, might actually be more favourable

than astronomers previously calculated.

Anna: Why would having two equal mass stars make it

easier for planets to form?

Avery: It has to do with gravitational stability.

When you have two stars of similar mass,

their gravitational influence on the

surrounding disc of planet forming material

is more balanced and predictable. There's

less chaotic variation in the gravitational

forces acting on the disc. Which means there

are stable regions where material can

accumulate and grow into planets.

Anna: What about unequal binary systems? One big

star and one small one.

Avery: Those systems can still host circumbinary

planets, but the dynamics are more complex.

The larger star dominates gravitationally,

and the smaller star creates additional

perturbations that can make certain orbital

regions unstable. It doesn't mean planets

can't form, but the stable zones might be

more limited or located at different

distances.

Anna: This has implications for the search for

habitable worlds, doesn't it?

Avery: Very much so. If circumbinary planets

are more common than we thought, especially

in equal mass binaries, that increases the

overall number of potential planetary

environments in the Galaxy. Some of these

could potentially be in the habitable zone,

the region where liquid water could exist on

a planet's surface.

Anna: Although I imagine having two suns would

complicate the climate situation

significantly.

Avery: You're absolutely right. The climate on a

circumbinary planet would be fascinatingly

complex. You'd have variations in heating

depending on the orbital positions of both

stars relative to the planet. Some times of

the year, both suns might be on the same side

of the sky, providing intense combined

heating. Other times they'd be on opposite

sides, creating more balanced illumination.

Anna: How did researchers arrive at these

conclusions about circumbinary planet

frequency?

Avery: They combined observational data from

telescope surveys with sophisticated computer

modelling of how planets form in binary star

systems. By simulating thousands of different

scenarios with various binary configurations,

they could identify patterns about which

systems are most likely to host planets.

Anna: Are there any specific systems astronomers

are now targeting for follow up observations?

Based on these findings, the research

definitely.

Avery: Points to equal mass binaries as high

priority targets for planet hunting

campaigns. Missions like NASA's upcoming

Nancy Grace Roman Telescope and continuing

observations from ground based facilities

will be keeping a close eye on these systems.

Every new circumbinary planet we discover

helps refine our models.

Anna: It's exciting to think those iconic twin

sunset scenes from Star wars might be more

common in the universe than we realised.

Avery: It really is, Anna. Um, the universe keeps

proving that the reality can be just as

spectacular as science fiction, Sometimes

even more so.

Anna: And for our final storey today, Avery, we're

talking about a discovery that touches on one

of astronomy's biggest questions. The search

for life beyond Earth. Scientists have

detected a molecule critical to life in

interstellar space for the first time. Tell

us about this breakthrough.

Avery: This is genuinely exciting, Anna. Uh, for the

first time ever, astronomers have detected

ethylenamine, a molecule that plays a

crucial role in forming cell membranes

floating in the vast spaces between stars.

This discovery has profound implications for

how we think about the building blocks of

life in the universe.

Anna: Let's start with the basics. What exactly is

ethyl enamine and why is it so important to

life?

Avery: Ethylenamine is an organic molecule that's a

key component of phospholipids, which are the

primary building blocks of cell membranes.

Think of cell membranes as the walls and

gates of cells. They define the boundary

between the inside and outside of a cell and

control what goes in and out. Without

molecules like ethylenamine, you can't build

functional cell membranes. And, uh, without

cell membranes, you can't have cells as we

know them.

Anna: Though this is truly fundamental to life, at

least life as we understand it. Where was

this molecule detected?

Avery: The discovery was made in a molecular cloud,

one of these vast cold regions of space where

gas and dust accumulate and where new

stars and planetary systems eventually form.

These clouds are essentially stellar

nurseries. And finding life, building

molecules there suggest that the ingredients

for life might be getting incorporated into

planetary systems right from the start.

Anna: How do scientists actually detect specific

molecules in interstellar space? I imagine

you can't exactly collect a sample.

Avery: Great question. They use radio

spectroscopy. Every molecule has a unique

spectroscopic signature. Think of it like a,

uh, molecular fingerprint. Different

molecules absorb and emit light at specific

wavelengths. Radio telescopes can detect

these signatures, allowing astronomers to

identify what molecules are present in

distant clouds, even though those clouds are

trillions of miles away.

Anna: We've found other organic molecules in space

before, haven't we? What makes this discovery

special?

Avery: You're absolutely right, Hannah. Astronomers

have detected more than 200 different

molecules in interstellar space, including

amino um, acids and sugars. But

ethylnamine is special because of its direct

connection to cell membrane formation. It's

one thing to find amino um, acids, the

building blocks of proteins, but finding a

molecule that's essential for creating the

actual structure of cells takes us another

step closer to understanding how life's

fundamental architecture might arise.

Anna: Does this discovery change our thinking about

where the building blocks of life come from?

Avery: It definitely supports the hypothesis that

many of life's essential molecular

ingredients aren't created on planets after

they form, but rather arrive from space.

We already know that meteorites deliver

organic compounds to planets. We found amino

acids in meteorites that have fallen to

Earth. This discovery suggests that

even more complex life related molecules

could be delivered from space.

Anna: Though in a sense, the raw materials for

life might be common throughout the galaxy.

Avery: That's the tantalising possibility this

raises. If molecules like ethanolamine can

form in the harsh conditions of interstellar

space, then these building blocks might be

present in molecular clouds throughout the

galaxy. Every time a new planetary

system forms, it could be inheriting these

pre made components of life.

Anna: This doesn't mean life is automatically

everywhere though, right? Having the

ingredients doesn't guarantee you'll bake the

cake.

Avery: Exactly. This is about potential and

possibility. Having the molecular building

blocks is necessary for life, but it's not

sufficient. You still need the right

conditions for those molecules to assemble

into functioning biological systems. The

right temperature, pressure, energy sources,

solvents like liquid water, and probably a

host of factors we don't fully understand

yet.

Anna: What are the next steps for this kind of

research?

Avery: Astronomers will be looking for ethanolamine

and similar molecules in other molecular

clouds to see how widespread they are.

They'll also be searching for even more

complex organic molecules that might be

precursors to biological chemistry.

Every molecule we find helps us piece

together the storey of how inanimate

chemistry transitions to the chemistry of

life.

Anna: It's remarkable to think that the membrane

surrounding every cell in our bodies might

have had their chemical ancestors floating

between the stars billions of years ago.

Avery: It really is Anna, uh, it connects us to the

cosmos in a very tangible way. We're

not just made of stardust in an abstract

sense. The actual molecular machinery

of life may have origins that predate Earth

itself.

Anna: What a perfect note to end today's episode on

a reminder that we're part of a universe wide

chemistry experiment that's been running for

billions of years.

Avery: Well, that wraps up another day of space and

astronomy news. From NASA's Artemis

preparations to the discovery of life's

building blocks floating between the stars,

the universe continues to amaze and inspire.

Anna: It really does. Thanks so much for joining us

Hmm.

In this episode
