Webb Completes its First “Deep Field” With Nine Days of Observing Time. What did it Find?
About 13 billion years ago, the stars in the Universe’s earliest galaxies sent photons out into space. Some of those photons ended their epic journey on the James Webb Space Telescope’s gold-plated, beryllium mirrors in the last few months. The JWST gathered these primordial photons over several days to create its first “Deep Field” image.
Supernova algorithm classifies 1,000 dying stars without error
A newly developed algorithm is helping astronomers search through massive amounts of data from Zwicky Transient Facility categorizing powerful cosmic explosions called supernovas.
Pesky 'leap second' will be abolished by 2035
An international group of experts has voted to retire the leap second by 2035.
Black Holes Shouldn’t be Able to Merge, but Dozens of Mergers Have Been Detected. How Do They Do It?
Who knows what lurks in the hearts of some globular clusters? Astronomers using a collection of gravitational wave observatories found evidence of collections of smaller black holes dancing together as binaries in the hearts of globulars. What’s more, they’ve detected an increased number of gravitational wave events when some of these stellar-mass black holes crashed together.
Perhaps a Supervoid Doesn’t Explain the Mysterious CMB Cold Spot
For years cosmologists had thought that a strange feature appearing in the microwave sky, known as the CMB cold spot, was due to the light passing through a giant supervoid. But new research casts that conclusion into doubt.
Elusive intergalactic light from orphaned stars studied for 1st time
Astronomers have for the first time studied the elusive faint glow emanated by stars that have been ripped from their homes and now exist as cosmic orphans between galaxies.
NASA confident in SpaceX after raucous Twitter takeover by Elon Musk: report
NASA Administrator Bill Nelson said SpaceX CEO Gwynne Shotwell was reassuring during a recent conversation.
Catch the Geminid Meteor Shower; Plus, Watch RW Cephei Fade
The luminous Geminid meteor shower returns. We also meet a binocular-bright star that may be experiencing Betelgeuse-like convulsions.

NASA's TV coverage of Artemis I recovery included 'hat tip' to Apollo
There was something familiar about the hat Derrol Nail wore as he described NASA's Orion spacecraft splashing down from the moon. Not by accident, his ballcap evoked images of Apollo astronauts.
A Black Hole has been Burping for 100 Million Years
Black holes are gluttonous behemoths that lurk in the center of galaxies. Almost everybody knows that nothing can escape them, not even light. So when anything made of simple matter gets too close, whether a planet, a star or a gas cloud, it’s doomed.
The Large Hadron Collider reveals how far antimatter can travel through the Milky Way
The antimatter counterparts of light atomic nuclei can travel vast distances through the Milky Way before being absorbed, new findings have revealed.
Nudging a Space Rock
That’s one small change in an asteroid’s orbit, one giant leap for humanity.
Looking back from beyond the moon: How views from space have changed the way we see Earth
How does a stunning photo from Artemis 1 compare to other iconic views of Earth from the outside?
NASA green-lights asteroid-hunting space telescope for 2028 launch
NASA is moving ahead with the development of a spacecraft to hunt for potentially hazardous asteroids and aims to launch by June 2028.
NASA may unlock future James Webb Space Telescope data
Someday, you may be able to see fresh data from the James Webb Space Telescope as soon as the scientists who proposed gathering it do.
After Artemis 1, it will take NASA 2 years to send astronauts to the moon. Why so long?
With Artemis 1 now in the books, the focus is quickly shifting to the Artemis program's next phase: crewed flight. But that can't happen until several pieces fall into place.
'Vanishing stars' citizen-science project opens the skies to the public
Stars aren't supposed to simply disappear, yet countless bright objects that once appeared in the sky in the 1950s no longer do.
