Astronomers Detect Large Amounts of Oxygen in Ancient Star’s Atmosphere
Maunakea, Hawaii – An international team of astronomers from the University of California San Diego, the Instituto de Astrofísica de Canarias (IAC), and the University of Cambridge have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known – a “primitive star” scientists call J0815+4729. This […]

Astronomers Discover Class of Strange Objects Near Our Galaxy’s Enormous Black Hole
Maunakea, Hawaii – Astronomers from UCLA and W. M. Keck Observatory have discovered four more bizarre objects at the center of our galaxy, not far from the supermassive black hole called Sagittarius A*, that are now forming a class of their own. The study, which is part of UCLA’s Galactic Center Orbits Initiative, consists of […]

Astronomers Spot Distant Galaxy Group Driving Ancient Cosmic Makeover
Maunakea, Hawaii – An international team of astronomers funded in part by NASA has found the farthest galaxy group identified to date. With the help of W. M. Keck Observatory on Maunakea, Hawaii, the team confirmed the trio of galaxies called EGS77 dates to a time when the universe was only 680 million years old, […]

The ‘Cores’ of Massive Galaxies Found to Have Formed A Billion Years Earlier Than Previously Thought
Maunakea, Hawaii – A distant galaxy more massive than our Milky Way — with more than a trillion stars — has revealed that the ‘cores’ of massive galaxies in the universe had already formed 1.5 billion years after the Big Bang, about 1 billion years earlier than previous measurements revealed. Researchers published their analysis in […]

Unpredicted Stellar Black Hole Discovered
Maunakea, Hawaii – Our Milky Way Galaxy is estimated to contain 100 million stellar black holes – cosmic bodies formed by the collapse of massive stars and so dense even light can’t escape. Until now, scientists had estimated the mass of an individual stellar black hole in our Galaxy at no more than 20 times […]

NASA Scientists Confirm Water Vapor on Europa
Maunakea, Hawaii – Forty years ago, a Voyager spacecraft snapped the first closeup images of Europa, one of Jupiter’s 79 moons. These revealed brownish cracks slicing the moon’s icy surface, which give Europa the look of a veiny eyeball. Missions to the outer solar system in the decades since have amassed enough additional information about […]

Astronomers Catch Wind Rushing Out of Galaxy
Researchers Directly Observe for the First Time a Huge Outflow of Gas Extending Far Beyond a Galaxy Maunakea, Hawaii – Exploring the influence of galactic winds from a distant galaxy called Makani, University of California, San Diego’s Alison Coil, Rhodes College’s David Rupke and a group of collaborators from around the world made a novel […]

A Crisis in Cosmology
Maunakea, Hawaii – A group of astronomers led by University of California, Davis has obtained new data that suggest the universe is expanding more rapidly than previously thought. The study comes on the heels of a hot debate over just how fast the universe is ballooning; measurements thus far are in disagreement. The team’s new […]

Massive Filaments Fuel the Growth of Galaxies and Supermassive Black Holes
Maunakea, Hawaii – An international group of scientists led by Hideki Umehata of the RIKEN Cluster for Pioneering Research, a branch of Japan’s largest scientific research organization, has made detailed observations of the filaments of gas connecting galaxies in a large protocluster in the early universe. Based on direct observations they found that, in accordance […]

Oldest Galaxy Protocluster Forms “Queen’s Court”
Maunakea, Hawaii – Using multiple Maunakea Observatories – the Subaru Telescope, W. M. Keck Observatory, and Gemini Observatory – an international team of astronomers has discovered the earliest protocluster ever found; it is comprised of a collection of 12 galaxies in the constellation Cetus, which were observed as they were about 13 billion years ago.
