Happy birthday #GW150914! 11 years ago today, we caught our first gravitational wave, and founded a new type of astronomy A decade later, we now have hundreds of observations! 🔭🧪🎂

It's #NeutronStarWeek! Come with me on a tour through the Universe to meet some iconic neutron stars: pulsars, magnetars, mergers & more! But let's start 130,000,000 light-years away, with two neutron stars that are no more... 👀 #Astronomy #NeutronStars

Read about how recent work, including by yours truly, is revealing hierarchical mergers and evidence for multiple subpopulations in this lovely APS physics viewpoint article physics.aps.org/articles/v19...

Evidence Mounts for Hierarchical Black Hole Mergers

Different analyses of gravitational-wave observations are converging on evidence for a distinct population of massive black hole binaries produced through repeated mergers.

We're delighted to announce that Dr Isobel Romero-Shaw has won the 2026 Caroline Herschel Prize Lectureship. Her lecture, at the University of Bath in November, is titled 'Violent Beginnings Have Violent Ends: Deciphering the Origins of Binary Compact Object Collisions with Gravitational Waves'. ⤵️

Happy Pride month to the whole LGBTQNJ+ rainbow!

Hi everyone I wanted to show a couple features of my website. Firstly, a page which shows evolutions of the binary black holes we have detected with @ligo.org @egovirgo.bsky.social @kagra. Click the link to learn more! nihargupte.com/blog/catalog... #blackholes

The President's Budget Request proposes a 47% cut to NASA Science, a 55% cut to NSF, and a 13% cut to the DOE Office of Science. AAS President Dr. Dara Norman sent a call to action to AAS members via email today. Urge your members of Congress to reject these cuts now! aas.org/reject-2027-...

very cool astrobite article for a new paper I'm involved with led by Mor Rozner 🧪🔭😎

From Viviana Cáceres: Only a tiny fraction of black hole binaries produce gravitational waves with measurable eccentricity. What does the eccentricity distribution tell us about how these binaries formed? ⚛️ 🔭 ☄️ 🧪 astrobites.org/2026/03/25/pinhole-eccentricity-distribution/

Last week over 400 scientists of the @ligo.org - Virgo - KAGRA Collaboration met in Pisa, Italy for the LVK Meeting, the biannual gathering of the global community studying gravitational waves 🌟🌍

Our fourth LIGO @egovirgo.bsky.social KAGRA observing run has now drawn to a close. We will be busy analysing data for a while to come—watch out for more discovery announcements. We will be back next year observing.docs.ligo.org/plan/

Mirror, mirror, reflecting our [LASER] beam... What is the loudest [gravitational wave] signal that we've seen? It’s #GW250114! (Yes, it’s been two weeks since it was announced, but I can still celebrate! 🎉 ) #EinsteinWasRight #HawkingWasRight @ligo.org @egovirgo.bsky.social

Occupation: Student'nt Thanks @pinkastrophysicist.bsky.social for making me the delicious cake and taking this photo of me being equally excited and terrified 5 minutes after submitting my PhD 🥰🎂🧑‍🎓

Front page news! 📰 Monash PhD researcher Christian Adamcwicz leads new LVK results revealing the mysterious 40 M☉ gap in black hole populations. Exciting clues about how the universe’s heaviest stars live and die! #BlackHoles #LVK #Astrophysics www.theaustralian.com.au/science/grav...

Results from the first part of our fourth LIGO @egovirgo.bsky.social KAGRA observing run are out today! We're pleased to share the largest catalog of gravitational-wave observations with more discoveries of black holes and neutron stars 📰 arxiv.org/abs/2508.18082 🔭🧪⚛️☄️ #GWTC4

Congrats to everyone in the LVK collaboration who worked so hard to get these exciting results out 🤩🧪🔭

JWST slays with this bisexual lighting for the super fascinating bullet cluster 😍🌈

Dr. Skylar Grayson@skylargrayson.bsky.social · last yr.

Hold on to your butt because I am OBSESSED with this new JWST image 😍😍😍 This is the bullet cluster, and what you’re looking at is actually three different types of data that provide some of the strongest evidence for dark matter out there… (1/n) 🔭🧪 📸: NASA, ESA, CSA, STScI, CXC

Welcome to a new era in astronomy and astrophysics ✨🔭🧪 Get ready to join us virtually for the reveal of Rubin's first images! #RubinFirstLook 🗓️ June 23, 2025 ⌚️ 11am US EDT 🔗 ls.st/rubin-first-look-livestream

The gang are all here! Today we resumed our fourth observing run with LIGO Hanford, LIGO Livingston, Virgo, KAGRA and GEO all observing together! You can check detector status live at online.ligo.org ☄️🔭🧪

Did you know NASA science is facing a 50% budget cut??? Please read this @astrobites.bsky.social post to learn more about it and what you can do astrobites.org/2025/04/15/h...

NASA Needs Your Help!

NASA is facing severe budget cuts that would cancel missions ready to be launched, put tens of thousands out of a job, and set science back decades. We need your help to ask congress to prevent these ...

Publication day! With @sarinastro.bsky.social , Eric Howell, @plasky.bsky.social and Eric Thrane, we explore a hypothetical coincident neutron star-black hole merger and fast radio burst. We hope this work helps pave the way for future multimessenger detections! 🔭🧪⚛️ journals.aps.org/prd/abstract...

I made this the other night while procrastinating, mainly because I thought all the posts about the blackout were boring. It feels like there is momentum bringing people together!

The best dark sky in the world - the Atacama Desert in Chile, which hosts many @eso.org telescopes - is under threat from an industrial project. 🔭 Astronomers can sign a petition in favour of moving the planned industrial project: docs.google.com/forms/d/e/1F...

World's darkest and clearest skies at risk from industrial megaproject

On December 24th, AES Andes, a subsidiary of the US power company AES Corporation, submitted a project for a massive industrial complex for environmental impact assessment. This complex threatens the pristine skies above ESO’s Paranal Observatory in Chile’s Atacama Desert, the darkest and clearest of any astronomical observatory in the world [1]. The industrial megaproject is planned to be located just 5 to 11 kilometres from telescopes at Paranal, which would cause irreparable damage to astronomical observations, in particular due to light pollution emitted throughout the project’s operational life. Relocating the complex would save one of Earth's last truly pristine dark skies.

Exciting news! We’re thrilled to announce that tapir Yuna gave birth to a rare and endangered Malayan tapir calf Sunday night. The newborn, covered in distinctive white spots and stripes resembling a fuzzy walking watermelon, is only the second tapir born in our 120-year history.

ESO has some fantastic images of comet C/2024 G3 from their observatory in Chile 🧪🔭 Credit for this one belongs to F. Millour/ESO

The most shocking part of this photo are the words that have not been painted over as yet. They aren't even all "DEI" words. And yet, they are being wiped away. A re-write of history's lessons, the removal of the things that build a functioning society, to please the Emperor.

Assuming we make it through the next couple of decades, this will be an incredible image for future historians/students of the Trump era

Here is a highly recommended thread that summarizes what has happened in scientific landscape in the US since Trump's inauguration. It makes for dystopian reading ⬇️
