🌌 Boom goes the dandelion. A #Caltech-led team of astronomers have mapped, for the first time in 3D, the location and movement of filaments in the Pa 30 nebula—the aftermath of a supernova recorded by Japanese and Chinese astronomers in 1181. The remnants of this ancient stellar

Phenomenon Friday 🎆 I look like a giant fireball and am made of hot gas - mostly hydrogen. I shine bright in the night sky due to the immense pressure in my core, which causes my hydrogen to fuse into helium for most of my life. This process, called nuclear fusion, generates

Just WOW. An intense fireball captured by 国立天文台 すばる望遠鏡’s Live Cam above our telescope domes ☄️ Maunakea’s views never cease to amaze - so humbled by the awe and wonder of this special place ✨ youtu.be/jzdoNfIqnfY

Today we celebrate John O'Meara and his 6 years of scientific leadership at Keck Observatory. From Nobel celebrations to spearheading cutting-edge technology, John’s dedication to our mission is out of this world! 🎉🔭

We are #hiring for a new team member to join our Observing Support department as a Staff Astronomer I. If you're passionate about unraveling the mysteries of the universe, are a natural problem solver with observing experience, software skills, mechanical know-how, and stellar

The annual Maunakea Coin Contest is open! The winning design will be available as a bronze coin at the First Light Bookstore at the Visitor Information Station on Maunakea, and aluminum versions will be available at events throughout the year. The designs submitted for each

Hau'oli Makahiki Hou! Wishing you a year of curiosity and cosmic connection - keep looking up! 📷Andrew Richard Hara

🔭Using Keck Observatory data, astronomers have, for the 1st time, traced a fast radio burst (FRB) to the edge of an 11.3B-year-old galaxy, challenging the idea that FRBs are expected to originate in star-forming regions. How diverse are their origins? 👉keckobservatory.org/fbr/

Hubble got the bullseye! 🎯 The Bullseye Galaxy, that is. The galaxy's nine rings were caused by a blue dwarf galaxy (seen just at center-left) diving through the Bullseye about 50 million years ago: go.nasa.gov/4aSwbus

Keck Observatory and Hubble have captured a cosmic bullseye! The gargantuan galaxy LEDA 1313424 is rippling with nine star-filled rings after an “arrow” shot through its heart. But what's to blame? 👉keckobservatory.org/bullseye/ 👀

W. M. Keck Observatory appoints T. Ilihia Gionson as First Chief of Public Affairs - E komo mai! T. Ilihia Gionson keckobservatory.org/gionson/

Be still, my Tombaugh Regio! Pluto’s heart-shaped feature makes it easy to love—but wait, didn’t we help demote Pluto? 🤔"Pluto went from the smallest, oddball planet to the largest, best-studied, and first of a new class. That’s a promotion!" - Josh Walawender, Staff Astronomer.

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

Evidence from Keck Observatory confirms WR 104 is not a “Death Star,” proving what astronomers have suspected for years. Its orbit is tilted 30-40 degrees away from us, sparing Earth from a potential gamma-ray burst👉keckobservatory.org/pinwheel/ 📽️W. M. Keck Observatory/Adam Makarenko

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

Meet FCC 224: a dwarf galaxy lacking dark matter, challenging conventional galaxy formation models. Could it be that #galaxies have more variety in how they form and evolve than previously thought? 👉keckobservatory.org/dmf-dwarf-gala… 📷:Hubble #astronomy #maunakeaobservatory #hawaii

Congrats to our galactic colleague Hubble - what an incredible 35 years it has been! "The scientific combination of Keck Observatory and #Hubble over their lifetimes is one of the most powerful ever made in astronomy." - John O'Meara, Chief Scientist.
