The DESI Legacy Imaging Survey Releases the Largest 2-D Map of the Universe

The newest DESI Legacy Imaging Surveys map covers three-quarters of the sky and catalogs nearly four billion objects. This publicly-available database contains stars, galaxies, supernovae, gravitational lenses, and much more.

The 20th Data Release (DR 20) of the Sloan Digital Sky Survey (SDSS) is Here!

The Sloan Digital Sky Survey (SDSS) has officially launched its twentieth data release (DR20), featuring updated data from multiple observations projects.

Pulsar Timing Arrays Could Look for Evidence of Dark Matter Stars

Pulsar Timing Arrays have been used to observe the background of gravitational waves in our galaxy. We aren't certain of their origin, but a new study shows a strong source could be early supermassive giants known as dark stars.

New Study Expands Search for "Dark Photons," a Leading Dark Matter Candidate

Cross-disciplinary research at Perimeter Institute and University of Maryland shows that dark photons could be lurking in more places than previously thought.

Penultimate Lunar Occultations Inbound for Jupiter, Venus and More in September

The Moon is busy in September. Coming off of eclipse season in August, the Moon visits no less than two planets, two bright stars and one open cluster in September, as it heads towards the Full Harvest Moon of 2026 on September 26th. No matter where on Earth you happen to be observing from this month, chances are, there’s an occultation of a bright celestial object by the Moon coming to a sky near you.

Astronomers See How a Centaur Can Become a Comet

In 1992, Centaur 450P/LONEOS had a close encounter with Saturn, shifting its orbit closer to the Sun. Now astronomers can observe how a small icy body transforms into a comet over time.

Physicists Determine Cause of "Runaway" Supermassive Black Hole

Researchers at UCSB and UT Austin have determined that a galactic merger kicked a supermassive black hole into intergalactic space.
