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.

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.

On 13 December, the first of a new generation of satellites designed to revolutionise weather forecasting in Europe will take to the skies. ESA and the European Organisation for the Exploitation of Meteorological Satellites (Eumetsat) invite you to follow the live coverage for the launch of the first Meteosat Third Generation satellite starting from 19:40 CET on ESA Web TV.
Life on Proxima b Is Not Having a Good Time
The nearest known exoplanet to Earth, the planet orbiting Proxima Centauri, experiences some pretty nasty space weather from its parent star. But previous work on the space weather of Proxima relied on a lot of assumptions. The bad news is that new research has confirmed the grim picture.
