As the most volatile part of the research pipeline, early-career researchers absorb the brunt of any funding uncertainty.

It’s extremely encouraging to see the Science, Innovation and Technology Committee taking this so seriously and pressing #STFC on the consequences of the new funding framework.

Anyway, so freaking delighted & proud to see #MIRI take such a prominent role in one of the most exciting areas of astrophysics research right now (IMHO), and to be able to play a role in making this happen. 🔭

We only have 2 spectroscopically-observed galaxies at z > 14, so clearly we need more data. #JWST is spending some 330 hrs in Cycle 4 observing galaxies beyond redshift 10 with mid-IR spectroscopy - so we're going to be learning a lot more! scixplorer.org/abs/2025arXi...

Helton et al argue that the spectrum of GS-z14 adds to the weight of evidence that our theoretical models aren't successfully predicting galaxy evolution at very high redshifts (but there are good ideas for why that might be the case!) scixplorer.org/abs/2025arXi... 🔭

Long-winded title for a paper showing an extraordinary dataset - a 34-hr exposure of a redshift 14 (!) galaxy with MIRI LRS on #JWST. Beautiful >4-sigma detection of H-alpha in a galaxy observed when the Universe was only ~2% of its current age scixplorer.org/abs/2025arXi...

With the first Ariane 6 with four boosters, our fleet of rockets is complete 🚀

We will continue to work on upgrades to reduce costs, make our launch systems more robust and launch more often.

For example, the powerful P160C rocket motor will replace P120C on both Ariane 6 and Vega-C rockets.

"Isaacman says that for NASA to achieve this goal, it aims to hire the majority of its thousands of related contractors as agency employees instead."

The best!!

A screenshot of Google's AI Overview answer to the question "is haggis an animal". It says "Yes, the haggis is a small, furry mammal native to Scotland" and goes on to give the typical "asymmetrical legs" details.

The Scottish have won the AI Wars.

Two images of a planetary nebula in space. The image to the left, labelled “Euclid & Hubble”, shows the whole nebula and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula and this region is the image to the right, labelled “Hubble”. It shows the multi-layered bubbles, pointed jets and circular shells of gas that make up the nebula, as well as the central star, in greater detail.

Wowowow - our @science.esa.int Hubble's picture of the month for March is the Cat's Eye Nebula, from combined images of #Hubble and #Euclid. Euclid's wide field and low surface brightness sensitivity brings out an external shell. Incredible image. esahubble.org/images/potm2... 🔭

Incredible substorm with the lunar eclipse just now in Fairbanks, Alaska. Legendary.

Operations engineers in the Main Control Room at the European Space Operations Centre (ESOC) during Solar Orbiter's launch in February 2020. The image shows people sitting at a long console with many computer screens. The people are watching the computer screens and pointing to things outside of the image frame.

🛰️☀️ Solar Orbiter hits its 9th perihelion this week, diving to 0.29 AU from the Sun.

This kicks off a 10 day Remote Sensing Window where teams rapidly plan, image, analyse and reorient the spacecraft – a showcase of ESA’s teamwork near our star. ⭐

#LunarEclipse FAQ:

Q: Is it safe to look at?
A: Absolutely! Unlike a solar eclipse, there's no UNsafe time to look at a lunar eclipse.

Q: Do I need a telescope?
A: Nope! Best view is with naked eye. Just look up!

Q: Does the eclipse portend terror & doom?
A: Not at all! The news has that covered.

Yes good point! But contributing to classification problems is very different (and much more accessible) than theoretical physics/cosmology, to which many of the emailers seem to gravitate but for which they don't have the mathematical skills.

Astronomer friends! We're kicking off our 2026 series of JWebbinars with this even on March 4th, on #JWST science communications. Details and registration link below! 🔭

so yeah no answer to your question but I agree it feels unkind to dismiss them completely - but I also have no time to engage (and they tend to be very resistant to being told where they are wrong).

I am often intrigued by crackpot emails! The senders often have a decent grasp of some aspect of the physics (i.e. they have read about challenging topics, worked to understand), but then they have taken a wrong turn or made a bad connection somewhere. They're not usually totally crazy.

In case you’re just waking up, the U.S. has teamed up with Israel overnight to start an illegal war of regime change, apparently on a presidential whim with no involvement of Congress, and they are already committing horrific atrocities.

A white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.

Our first glimpse of comet 3I/ATLAS from Juice's science camera 😍☄️

The precious data from the mission's November observations of the interstellar comet arrived on Earth last week. Teams are now digging in to discover what they reveal.

Stay tuned for updates!

On the reading list for when I get back from vacation - great work and thanks for sharing.

As promised yesterday: a new alternative model for Little Red Dots. Maybe they're not stars powered by black hole accretion ... maybe they're globular clusters in formation! That's the suggestion in a new paper led by John Chisholm, anyway. It sounds impossible, but hear me out: 🧪🔭☄️

Yes that is great! Daens for me is a good Belgian contender (hard to find these days). Trois Couleurs: Bleu, Indochine, Cinema Paradiso, Y tu mama tambien, City of God, Parasite are the ones that come to mind, but so many more.

SO MANY I'd have no idea how to pick one.

This richly detailed image of the Lagoon Nebula was captured by the VST at our Paranal Observatory.

A giant cloud of gas and dust, this nebula is creating bright young stars, and is home to young stellar clusters.

I'll try to word this responsibly.

My understanding is constellations so far launched do not irretrievably compromise searches for Potentially Hazardous Asteroids.

Eventually, a big enough constellation would do so. I don't think anyone has simulated the effect of this many satellites. 🔭🧪
