On September 14, 2015, the Laser Interferometer Gravitational-wave Observatory (LIGO) detected gravitational waves from the merger of two black holes 29 and 36 times the mass of the Sun. Such an event is expected to be d...

Do you remember science classes from way back when? All those laws and rules made it seem like everything was logical and well behaved. Then perhaps with television and movies being a big part of your life you began to w...

The new vehicle replaces the company's original SpaceShipTwo, which was destroyed in a fatal accident 15 months ago --

California-based SpaceX is already warning that failure is likely in Wednesday's attempt at landing its Falcon 9 rocket, following the launch of a European satellite into a distant orbit.

Calling it music is a stretch, but that's exactly how the Apollo 10 astronauts described the creepy sounds they heard while swinging around the farside of the moon in May 1969. During the hour they spent alone cut off fr...

Watching the inky-black shadow of a Jovian moon slide across the cloud-tops of Jupiter is an unforgettable sight. Two is always better than one, and as the largest planet in our solar system heads towards opposition on M...

US astronomers announced last month they may have found a ninth planet beyond Neptune, but conceded they had no idea where on an estimated 10,000-20,000-year orbit it might be.

  We've achieved amazing things by using chemical rockets to place satellites in orbit, land people on the Moon, and place rovers on the surface of Mars. We've even used ion drives to reach destinations further afield i...

Former NASA astronaut Ron Garan has joined high-altitude balloon company World View as its chief pilot, the company announced Feb. 23, making him the latest astronaut to seek a post-agency career in the commercial spacef...

Five moons orbit the dwarf planet Pluto: Charon, Nix, Hydra, Kerberos and Styx.

Astrophysicists are still guessing at exactly how massive gassy planets - orbiting dizzyingly close to their stars - came to exist. Dr. Paul Sutter talks us through the physics of 'roaster planets,' 'pegasids,' and 'epis...

Charon was discovered in 1978 and named for the discoverer's wife, as well as the mythological ferryman. Pluto and Charon are considered a binary planet system.
