A "forbidden" merger between two black holes may not have been quite as impossible as previously thought. New research that suggests the black holes involved were smaller than first calculated.

A NASA Launch Services (NLS) II contract has been awarded by the agency to Relativity Space Inc., and its Terran R launch service in accordance with the contracts on-ramp provision. The Terran R launch service will be av...

European Space Agency astronaut Sophie Adenot paid tribute to Star Treks real-world contributions to science and exploration by wearing Captain Pikes Starfleet badge aboard the International Space Station on the shows 60...

We've been searching for life on Mars for a long time, but so far we've come up empty. The fundamental problem is a Catch-22 involving two of the key ingredients for life. Life as we know it needs liquid water an...

Using ALMA, astronomers have watched as two stars come together to form a massive stellar binary, finding chaos that indicates they emerged from different backgrounds.

Using NASAs Chandra X-ray Observatory, scientists have discovered a new class of objects behaving unlike any they have seen before. Astronomers suggest these newly spotted objects in other galaxies may help solve not one...

"When you look up at the night sky, most of those stars have planets."

An international team led by researchers from the University of So Paulo (USP) in Brazil has developed an innovative method to identify stars that have consumed the planets around them. The technique detects variations i...

Stephan's Quintet contains the most well-studied compact galaxy group. Japanese researchers have mapped star forming gas in the Quintet, along with its turbulence. The results show that the Quintet is an evolved grou...

Last November, NASA and its European partners launched the Sentinel-6B satellite to improve hurricane forecasts, help protect infrastructure, and benefit commercial industries, including shipping. The satellite now is fl...

"We can - and must - get on the right path."

Key figures from Europe's space industry and other international players have converged on Paris to discuss how to advance the continent's ambitions in a global market dominated by the United States.

The crew of NASAs Artemis II mission - NASA astronauts Christina Koch, Victor Glover, and Reid Wiseman and CSA (Canadian Space Agency) astronaut Jeremy Hansen - visited Huntsville, Alabama, Sept. 1, 2026, where they met ...

Astronomers have long searched for Dyson spheres as a sign of advanced alien civilizations. But if an alien civilization is dependent on advanced computing, we may be better served by looking for a Slysh halo.

Toward the end of their lives, low-mass stars undergo an abrupt dip in brightness, also known as the luminosity bump. While the endpoint of this bump is well understood, its onset has remained elusive. Now, in a paper pu...

United States Space Command just held its first-ever "Apollo Maneuvers" exercise, which saw spacecraft maneuvering in orbit through simulated contested environments.

New observations of the composition of distant galaxies offer insights into the earliest phases of the universe and confirm decades of scientific understanding of the elements and particles produced by the Big Bang, acco...

Until just over a decade ago, ring systems were thought to be exclusive to the giant planets of the solar system, such as Jupiter, Saturn, Uranus and Neptune. However, in 2013, a small body barely 250 kilometers (155 mil...

On Sept. 9, 1982, the first private rocket, Conestoga 1, launched into space from a Texas cattle ranch. Here's why it mattered.

Anak Krakatau erupted, and satellites were watching.

Video: 00:04:20 Witness how over the last eight years, the ESA/JAXA BepiColombo mission has been travelling through the inner Solar System and aligning itself with Mercury's orbit. So far, it has travelled 9.9 billio...
