On Mars, the past is written in stone—but the present is written in sand. Last week, Perseverance explored inactive megaripples to learn more about the wind-driven processes that are reshaping

Researchers hope to use neutrinos to find the sources of cosmic radiation. New algorithms out of Bochum are aiding in the search, and have also eliminated a few candidates.

As missions like Kepler and TESS discovered more rocky exoplanets in recent years, scientists looked forward to the launch of the JWST. The powerful space telescope has the ability to

The universe captured by Hyper Suprime-Cam (HSC), the ultra-wide field of view camera, is truly magnificent. In this image, two spiral galaxies in the lower right immediately catch the eye:

Another U.S. military mini shuttle blasted off Thursday night to conduct classified experiments in space.

More than 5,000 planets have been discovered beyond our solar system, allowing scientists to explore planetary evolution and consider the possibility of extraterrestrial life. Now, a UC Riverside study published

NASA’s Artemis II mission, set to send four astronauts on a nearly 10-day mission around the moon and back, will advance the agency’s goal to land astronauts at the moon’s

Researchers at Durham and collaborators in the Dark Energy Spectroscopic Instrument (DESI) mission have proposed a bold new theory that black holes could be converting matter into dark energy.
