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
A lot of people ask me how I stay level headed with everything that’s happening like I didn’t grow up when Bush stole an election, failed to stop 9/11, launched two bullshit wars and Homeland Security, got caught doing straight up torture, and Katrina where Black people were abandoned & then hunted.
i don't want to hear your most boomer complaint. what's your most millennial complaint?
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!? 🔭

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...
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.

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.

More here.

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.
NASA budget would cancel dozens of science missions, lay off thousands

NASA released more details about its proposed fiscal year 2026 budget May 30, canceling dozens of science missions and cutting thousands of jobs.

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.

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
