An amazing result out of #AAS247 - Astronomers discover the first galaxy-wide wobbling black hole jet in a disk galaxy keckobservatory.org/vv340a/ Congratulations to @justtheletteru.bsky.social, @justinkuder.bsky.social and the whole team for this incredible discovery

We had an observing run on @keckobservatory.bsky.social yesterday. Despite the pessimistic forecast, @marinabianchin.bsky.social pulled through and ended up getting abundant photons from nearby galaxies using #OSIRIS #laserguidestar. This is a gorgeous shot of our laser in action from the camera 🔭

This week, Keck Observatory superstars are attending the #AAS247 meeting in Phoenix. Visit us daily at the Maunakea Observatories Booth 212 for science and swag! The Exhibit Hall is open from 9am-6:30pm MT mon-wed, and until 2 pm on Thurs.

We'll be watching! 🔭😱 bigislandnow.com/2025/12/18/g...

🔭 Happy 1st Light Anniversary to Keck I! 35 yrs ago, w/ only 9/36 mirror segments, Keck I imaged spiral galaxy NGC 1232, proving the impossible could be done. Excited for next 35 yrs of scientific impact! #keckobservatory #astronomy

Congratulations to our brilliant colleagues at NASA for recently achieving 6,000 exoplanets discovered! We are honored to play a role in this pivotal research and look forward to further collaboration as we expand our understanding of the diversity and nature of other worlds.

Meet SN 2021yfj, a rare “stripped-to-the-bone” supernova, providing the first, direct look inside a dying star. 🌌 This discovery was made possible through the collective efforts of researchers around the world, with Keck Observatory data playing a key role. 👉 keckobservatory.org/sn2021yfj/

In person registration is now open for our 31st Annual Keck Science Meeting, Sept. 18-19 at UCLA. This annual gathering unites Keck Observatory users from partner institutions to discuss groundbreaking discoveries and spark new collaborations. Reserve your spot: kecksciencemeeting.org

To ‘Infinity’ and Beyond! The "Infinity" galaxy, that is. 💫 This discovery provides evidence of a new pathway for black hole formation with the help of Keck Observatory data! Reach for the stars ✨🔭 keckobservatory.org/infinity-gal...

🚨 Cosmic cameo alert! 🚨 On the latest @ShadowScientists.bsky.social, Bryce Bolin (Eureka Scientific) teamed up with observatory superstars Leo Alcorn, Matt Wahl & Josh Walawender to catch a rare guest from the galactic beyond: Comet 3I/ATLAS! 🌌☄️ Wanna comet along next time? 🛸✨ shadow.ucsc.edu ✨

A supernova's 'caged' jet uncovers the origin of a rapid X-ray burst—a puzzling cosmic outburst traced back to a colossal star explosion. But how does it all connect? 🔭 Dive into the mystery: keckobservatory.org/fxt/ @nupress.bsky.social #Astronomy

Congrats to our galactic colleague Hubble on 35 years in orbit! "The scientific combination of Keck Observatory & #Hubble over their lifetimes is one of the most powerful ever made in astronomy," reflects our Chief Scientist John O'Meara. Hoʻomaikaʻi 🎉 science.nasa.gov/missions/hub...

ISO: a passionate human being energized by building programs that make a lasting impact on community. Must be passionate about STEM education & delivering impactful outreach initiatives. Does this sound like you (or someone you know?) 👀

🚨Newly discovered #Asteroid2024YR4 may be headed for the Moon—and it's no ordinary space rock. Astronomers using Keck Observatory have determined its physical properties & potential origin🤯What & where?👉🔗 keckobservatory.org/2024-yr4/ 📽️ W. M. Keck Observatory/Adam Makarenko

"WR 104 you ARE NOT the father...I mean “Death Star,” - Maury Povich. Keck Observatory proves what astronomers have suspected for years. Earth is spared from a potential gamma-ray burst from WR 104...but how?🤔 👉 keckobservatory.org/pinwheel/ 📽️W. M. Keck Observatory/Adam Makarenko

The dynamic duo Keck Observatory & Hubble enabled researchers to discover something curious in the solar system's Kuiper Belt... youtube.com/watch?v=JC-m... Galactic Triplets, perhaps?

We enjoyed having you onsite, Érika! Looking forward to your results - we want to help share the news!

For the first time, astronomers have traced a fast radio burst (FRB) to an unexpected home, hinting that the origins of these mysterious cosmic events might be more diverse than previously thought. How diverse? Learn more 👉https://www.keckobservatory.org/fbr/ #keckobservatory
