NASA’s Nancy Grace Roman Space Telescope will conduct a wide-area survey to study dark matter, dark energy, and the expansion of the universe across 11 billion light-years.

A newly detected gravitational wave, GW250114, is giving scientists their clearest look yet at a black hole collision—and a powerful way to test Einstein’s theory of gravity. Its clarity allowed ...

For those who watch gravitational waves roll in from the universe, GW250114 is a big one. It's the clearest gravitational wave signal from a binary black hole merger to date, and it gives researchers ...

The new year debuted with an unexpected space-related conspiracy theory on social media that made us forget about the 3I/ATLAS comet conspiracy that preceded it. An imminent alien contact (3I/ATLAS) ...

Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence on the formation of stars, galaxies and planets. The research, including ...

NASA announced on January 23, 2026, that the Nancy Grace Roman Space Telescope will study the dense regions of stars at the center of the Milky Way. The mission will focus on the galactic bulge to ...
