The origin of Saturn’s rings has been one of the most interesting puzzles in planetary science, and now new data from the Cassini spacecraft is helping to fill in the pieces, showing [...]

Where's the Kaboom? Astronomers Detect No X-Ray Emission From Recent Supernova Explosion

The supernova SN 2014J, as imaged by NASA’s Chandra X-ray Observatory. This image contains Chandra data, where low-, medium-, and high-energy X-rays are red, green, and blue respectively. The boxes in the bottom of the image show close-up views of the region around the supernova in data taken prior to the explosion (left), as [...]

A Troubled Start to a Triumphant Mission: 37 Years Since the Launch of the Voyagers

Voyager 2 begins its journey of exploration, 37 years ago today (20 August), with a rousing liftoff atop a Titan IIIE-Centaur booster from Launch Complex (LC)-41 at Cape Canaveral. Photo Credit: NASA

A quarter-century ago, this week, NASA’s Voyager 2 spacecraft became the first machine fashioned by human hands to travel close to the [...]

Astronomers Observe the Rhythm of Rare Type of Black Hole

Black holes are one of the most unusual and fascinating phenomena in nature, and now astronomers are learning more about a peculiar type of black hole, thanks to archived data from NASA’s Rossi [...]

Hot Summer of Resupply Concludes and Continues Aboard Space Station

Characterized by its X-shaped “windmill” of solar arrays, Europe’s fifth and final Automated Transfer Vehicle (ATV-5) is visible, attached to the aft longitudinal port of the International Space Station’s (ISS) Zvezda module. Photo Credit: NASA

A hot and feverish summer of International Space Station (ISS) resupply operations is in high gear, following the successful [...]

Dust in the (Interstellar) Wind: Seven Particles of Possible Interstellar Origin Identified in Samples Returned by NASA's Stardust Spacecraft

A team of researchers has identified seven dust particles that were returned to Earth in 2006 by NASA’s Stardust spacecraft, which might have originated in the interstellar medium. This false-color image shows a diffraction pattern created by one of these particles, named Orion. Image Credit: Zack Gainsforth

Following a preliminary analysis of the dust [...]

The private Dream Chaser crew vehicle, aiming to launch U.S. astronauts back to space, will “resume test flights this fall with sophisticated orbital software” while simultaneously pushing forward with [...]

The Improbable Case of the High-Energy Novae: NASA's Fermi Space Telescope Detects New Gamma Ray Sources

Novae typically originate in binary systems containing Sun-like stars, as shown in this artist’s rendering. NASA’s Fermi Space Telescope discovered that a nova in a system like this likely produces gamma rays (magenta) through collisions among multiple shock waves in the rapidly expanding shell of debris.
