"The forces that are needed to dislodge such a massive black hole from its home are enormous."
Ten years on from 'The Force Awakens', we look back at what's gone right and what's gone wrong.
More than a year after his initial nomination, the U.S. Senate has voted to confirm billionaire private astronaut Jared Isaacman as NASA administrator.
Aerospace engineer Michi Benthaus will become the first wheelchair user ever to reach space on Thursday (Dec. 18), and you can watch her historic launch atop a Blue Origin rocket live.
Rocket Lab is scheduled to launch four "DiskSats" for the U.S. Space Force at midnight on Thursday (Dec. 18), and you can watch the action live.
There could be liquid water trapped under the southern polar cap of Mars. But new observations suggest otherwise.
The HiRISE camera on NASA's Mars Reconnaissance Orbiter just notched a big milestone, snapping its 100,000th photo of the Red Planet.
Back in December 2015, the Force awakened in Star Wars, but it quickly went back to sleep.
SpaceX launched two Falcon 9 rockets, each carrying Starlink satellites, from Kennedy Space Cener in Florida and Vandenberg Space Force Base in California on Dec. 17, 2025.
Interstellar comet 3I/ATLAS was first detected on July 1st 2025 as it approached the Sun. Multiple telescopes, including the Very Large Telescope, the Hubble Space Telescope, and the James Webb Space Telescope have taken turns observing the comet as it continued on its hyperbolic trajectory out of the Solar System. It reached solar conjunction on October 21st, and on October 29th it came closest to the Sun.
"We're not certain if having widespread liquid pockets instead of a global ocean makes Titan more or less habitable."

The livestream will begin at 11 p.m. EST Dec. 18 (0400 GMT on Dec. 19), weather permitting.
We've rounded up the best Fallout gifts across the wasteland ahead of season two of the hit TV show, available to stream this month.
The Soyuz launched on Nov. 27, 2025 from the Baikonur Cosmodrome in Kazakhstan.
It has been a busy year for the European Space Agency’s Proba-3 mission. The satellite duo has already created more than 50 artificial solar eclipses in orbit since the mission operations began less than a year ago. The resulting data confirm Proba-3's ability to provide the missing puzzle piece in our observations of the Sun's enigmatic atmosphere – the corona.
The California startup Vast has opened a call for scientific research aboard its Haven-1 private space station, which is set to launch atop a SpaceX rocket next year.
Wednesday, Dec. 17, 2025: Your daily feed for the holiday flyby of interstellar comet 3I/ATLAS by Earth.
In astronomy, there is a concept called “degeneracy”. It has nothing to do with delinquent people, but instead is used to describe data that could be interpreted multiple ways. In some cases, that interpretation is translated into exciting new possibilities. But many times, when that happens, other, more mundane explanations are ignored for the publicity that the more interesting possibilities provide. That seems to have been the case for many “sub-Neptune” exoplanets discovered recently. Some theories have described them as Hycean worlds - worlds that are filled with water oceans or ice. But a new paper from Robb Calder of the University of Cambridge and his co-authors, available in pre-print on arXiv, shows that, most likely, these planets are almost all made of molten lava instead.
Dr. Larry Denneau of the University of Hawaii is nothing like your typical astronomer.
