The launch of Sputnik 1, Earth's first artificial satellite, paved the way for Moonwalking astronauts, robotic exploration of the planets, and space tourism.
By taking a 3-dementional look at the Hubble Deep Field, astronomers are learning about the earliest epochs of star formation.
Astronomers are heavily debating the best way to accurately inform the public about the risks of deadly impact on Earth.
In the ongoing struggle between expanding development and the protection of vanishing dark skies, it looks like there's a success story in the making outside Houston and possibly an example for other areas facing similar threats. The George Observatory, run by the Houston Museum of Natural Science and located about 50 miles from the…
With blistering heatwaves in the U.S. and devastating floods in Europe and Asia, perhaps we can take some comfort in knowing the solar system has places with far more inhospitable weather than Earth. Take Saturn's moon Titan. It's the only rocky world we know of that may have something like Earth weather, with oceans and…
An amateur astronomer has devised an inexpensive, home-built fireball monitor.
New evidence of ancient lakes on Mars suggest a much warmer past for the red planet.
An Arizona-based amateur astronomer is giving professional asteroid hunters stiff competition
The RHESSI craft has identified continued X-ray bursts on the Sun.
Astronomers have finally succeeded in modeling in three dimensions the behavior of a massive star during the final seconds of its life.
A new analysis of observations from the Solar and Heliospheric Observatory (SOHO) reveals detailed and unexpected weather patterns not only on the Sun's visible surface but down to depths of about 15,000 kilometers roughly two percent of the Sun's radius. The unexpected patterns include short-term giant storm systems analogous to Earth's hurricanes and Jupiter's…
Astronomers have uncovered a globular cluster being torn apart.
Spacecraft orbiting Mars may have confirmed that flares detected by amateur observers are due to Martian ices.
