A fireball exploded into life in the skies above Japan on Aug. 19, briefly turning night to day before fragmenting close to the horizon.

Viking 1 was launched by a Titan-Centaur rocket from Complex 41 at Cape Canaveral Air Force Station at 5:22 p.m. EDT on Aug. 20, 1975, to begin a half-billion mile, 11-month journey through space to explore Mars. The 4-ton spacecraft went into orbit around the red planet in mid-1976 and landed on Mars on July 20, 1976.

How a determined amateur astronomer may have hit on the identity of a Cepheid variable double star described by a beloved author.

A 1989 experiment offered the promise of nuclear fusion without the need for high temperatures, but this "cold fusion" was quickly debunked. Now, some of the techniques involved have been resurrected in a new experiment that could actually improve efforts to achieve practical fusion power

Acting NASA Administrator Sean Duffy says it's time for the agency to focus on the moon and Mars, not the "smorgasbord of priorities," like climate science, the agency has been directing its resources.

After five years, Pragmata could have been unambitious, but instead, it's a fascinating and innovative sci-fi game with heaps of potential.

An AI model trained on years of data from NASA’s Solar Dynamics Observatory can predict the sun’s future appearance and potentially flag dangerous solar flares

With no fuel or engines, tiny explorers will surf sun-warmed air alone to explore high in the skies of Earth and Mars

South Korea's K-RadCube satellite has arrived at NASA's Kennedy Space Center in Florida ahead of its launch toward the moon on the Artemis 2 mission next year.

Scientists are calling attention to an extremely common health problem that's been making astronauts uncomfortable: sinus issues.

This is part of a NASA-supported project hoping to fabricate "device-ready" wafers from space-grown crystals.

Southern Europe is once again in the grip of extreme summer heat. Soaring temperatures and bone-dry land have fuelled widespread wildfires, with the Iberian Peninsula among the regions hardest hit. Flames continue to sweep across parched landscapes, as these images show.

People in prisons and jails have contributed to some of the greatest ideas in mathematics

Warhammer 40K's most iconic real-time strategy series is back next year and under new leadership.
