You are amazing all you do, sounds exhausting but amazing

That’s a good list but don’t forget about the housing crash and recession of 08 right as we were finishing college

I would watch the shit out of that

Ok totally wish I’d thought to do this

😆 I did a trip recently ONLY two flights and longest was ONLY 11 hours I was like omg piece of cake. just be sure to sleep, those flights usually get in like 8am Sydney time, you get good sleep on the plane you then you’re on the right time when you land helps heaps.

America is so so so depressing, I’ve applied for Australian citizenship and was told I’d hear in June but nothing . Plead let me hear soon.

I’m trying to grow poblanos in WA Australia and it’s not going well others tell me I have chills thrips, tried neem oil but still new growth still looks weird 🌱🌱🌱

How do we post to the Astrosci feed ? If not 🔭?

The entire of America is falling into a dark cesspool of despair but my concern today was why was vizier down all day!? 🔭

Invisible Storm Lights Up Galaxy Cluster With Record-Breaking Radio Glow A vast, glowing halo enveloping a galaxy cluster has been discovered, defying expectations and pointing to turbulent cosmic forces as its power source.

A huge cloud of energised particles (known as a radio halo) revealed in new radio observations of a galaxy cluster 5 billion light years away. It’s the largest one ever seen, 20 million light years across 🧪🔭 scitechdaily.com/invisible-st...

Our global petition to save NASA science closes this Thursday, and we’re just shy of 15,000 signatures! Every name counts, this petition will be hand-delivered to members of Congress. Add yours today, Save NASA Science.

Chandra and Fermi also gone. Probes cancelled (so much work for nothing).

Hard to fathom why any sane person would do this, and hoping that there is a sane majority in Congress.

Watch the solar plasma curve along magnetic field lines like iron filings near a bar magnet. #stellarastro 🧪🔭

This work was funded in part by NSF.

Ziteng (Andy) Wang @zitengwang.bsky.social tells the story behind the discovery of this unusual long period transient, in his article for @aunz.theconversation.com.

Scaling relations of the global Hi mass fraction (top row) and Hi mass fraction within R25 (middle row) and R24 (bottom row) as a function of stellar mass, stellar mass surface density, and g25−i25 colour. For full caption please see the paper.

Recently published in PASA: "WALLABY pilot survey: Spatially resolved gas scaling relations within the stellar discs of nearby galaxies", Lee, S. et al. This is Figure 4. To read the paper visit doi.org/10.1017/pasa...

Is this higher than normal? By how much? It sounds like a good thing but as at least an astronomer if there’s no grad places for the many seeking them, is that good ? Usually in times of bad economy we have more seeking grad school than there are places

Lovely. I almost never see rainbows my whole life until Perth, now it’s so often and an amazing amount of double rainbows

Thin filaments in the tails of A2255, by DeRubeis+ (w/ myself, @jurjen93.bsky.social+)
A2255 is known to be a "mess" (arxiv.org/abs/2006.04808). The new @LOFAR-VLBI images add further complexity in the system, this time revealing small-scale structures in its radio galaxies

Optical images from the Dark Energy Survey (DES) are amazing, ... so much happening in the galaxy group. Exploring the sky never gets boring 🤩 #extragalactic #AstroSci #astronomy #galaxies

A day late posting but after a lot of hard work I give you the survey overview papers for the EMU & POSSUM ASKAP surveys #EMU survey arxiv.org/abs/2505.08271 and the #POSSUM survey arxiv.org/abs/2505.08272 🔭

This iconic NASA office changed climate science forever. DOGE plans to kill it The NYC space is where the term ‘black hole’ was coined and where James Hansen became famous for his warnings about climate change.

Nah I was still fairly early in the process and so far my findings seem to agree with the other paper

I love when you think you have a cool idea not done before spend several months working on it and then a paper drops doing what you were trying to do 🙁

A debut book on SETI and radio astro history by our very recent #NRAO Jansky Fellow, now Historian at AIP, @rebeccacharbon.bsky.social
I'm always so exited about our fellows' successes and achievements!

Blinking radio pulses from space hint at a cosmic object that ‘shouldn’t exist’ The slowest ‘cosmic lighthouse’ ever found challenges our understanding of how neutron stars work.

Check out this new cosmic weirdo discovered using @csiro.bsky.social's ASKAP telescope! It spins so slowly that you could watch both the Fellowship of the Ring and the Two Towers and still have time leftover before it finishes a full rotation

Satellite imagery captured by MAXAR showing the extent of the Eaton Fire in North Pasadena and Altadena.

A lot of #astronomers at JPL and Caltech have been affected by the #pasadenafires #californiafires , at least 150 have lost their homes! There’s funds being setup to help them with daily costs & recovery costs
