Universe
The cosmos is the ultimate physics experiment. Black holes, dark energy, gravitational waves, and the Big Bang — explore the universe through the lens of physics.
The comet that rambled past us from another star last year likely originated in a cold, isolated corner of the galaxy that had yet to gel into its own solar system, astronomers reported Thursday.
Ganymede is not only Jupiter's largest moon, but also the largest in our solar system and one of the few that hosts a massive ice ocean. Adding to this planet-like moon's uniqueness is the fact that a
Astronomers using the James Webb Space Telescope have made a surprising discovery about a galaxy long, long ago and far, far away: It isn't rotating. That's something only seen in the most massive, ma
For the first time, scientists have measured the instantaneous mind-blowing power of jets blasting from a black hole.
NASA's Psyche spacecraft will get a boost from Mars on Friday, May 15, passing just 2,800 miles (4,500 kilometers) from the planet's surface at some 12,333 mph (19,848 kph). The spacecraft will harnes
One night last fall, University of Cincinnati astrophysics graduate Paul Smith waited anxiously for data to start rolling across his computer screen from the James Webb Space Telescope a million miles
The European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) have signed a Memorandum of Cooperation to deepen collaboration in planetary defense, alongside a dedicated agreement
A new study, published in Science Advances, has refined some important details about the moon's largest and oldest impact crater, which stretches more than 1,200 miles (2,000 km) on the far side of th
Researchers at National Jewish Health have published new findings demonstrating that short-duration spaceflight may not significantly impact lower extremity joint structures, while also identifying a
A spiral galaxy's brilliant heart outshines everything within sight in a new picture from NASA's Webb Space Telescope.
The mysterious origin of an impressive cloud disturbance on Venus has now been revealed by a team including the University of Tokyo. Researchers used numerical models to show that an enormous 6,000-ki
NASA's home for experimental flight is welcoming more flyers to its already high-performing fleet as it continues to support science and aeronautics test missions—continuing the legacy of pioneers lik
Hawking radiation suggests black holes slowly evaporate by emitting particles, eventually exploding in the distant future.
What does the surface of Saturn's mysterious moon Iapetus look like? To help find out, the robotic Cassini spacecraft now orbiting Saturn was sent soa...
