Two US scientists say they've come up with a method of deflecting or destroying asteroids that could have dealt with last Friday's in less than an hour.
Russian scientists say they've managed to recover pieces of the meteorite that exploded over the Ural Mountains on Friday, but that much of it fell to Earth in Lake Chebarkul.
The European Space Agency's (ESA) Mars Express recently snapped a high-resolution stereo image of the southeast corner of the Amenthes Planum region on Mars, near the Palos crater and the mouth of a well-known sinuous valley, Tinto Vallis.
Astronomers believe they've now worked out the details of how supernova remnants can form cosmic rays.
A big problem with the use of electric rocket engines known as Hall thrusters has been erosion of their discharge channel walls, limiting their use to the inner solar system.
New data from NASA's Chandra X-ray Observatory indicates that a highly distorted supernova remnant may contain the most recent black hole formed in our Milky Way galaxy.
An asteroid the size of a small office block is due to whizz past Earth on Friday, traveling at over 28,000 miles per hour.
By tradition, the moons of Pluto have names associated with Hades and the underworld. But there's plenty of possibilities to choose from - and the discoverers of the planet's two tiniest moons are inviting the public to name them.
NASA's Landsat Data Continuity Mission (LDCM) made a textbook launch at 1:02 pm EST yesterday from Vandenberg Air Force Base in California.
UK engineers have carried out a detailed assessment of the risks from solar superstorms, and say governments need to do more to protect against them.
NASA's Curiosity rover has, for the first time, used the drill on its robotic arm to bore into a rock on Mars and extract a sample for analysis.
NASA's space telescope has captured a rather impressive image of a thin, glittering streak of stars known as the spiral galaxy ESO 121-6, which lies in the southern constellation of Pictor (The Painter's Easel).
An odd star that flashes like a strobe light may actually be a pair of young stars just a few thousand years old, says a team using the Spitzer and Hubble space telescopes.
William Shatner, who is perhaps best known for playing Captain James T. Kirk in the original Star Trek series, called the International Space Station (ISS) today for a chat with Canadian astronaut Chris Hadfield.
There's probably an Earth-sized planet with a comfortable temperature as little as 13 light years away, data from NASA’s Kepler space telescope implies.
The Seagull Nebula is a huge cloud primarily made of hydrogen gas that runs along the border between the constellations of Canis Major (The Great Dog) and Monoceros (The Unicorn) in the southern sky.
NASA's Interstellar Boundary Explorer (IBEX) spacecraft has helped explain the striking narrow ribbon of charged particles emanating from the boundary of the solar system.
NASA's Hubble Space Telescope recently managed to capture one of the most stellar views yet of nearby spiral galaxy Messier 106.
So-called super-Earths - rocky exoplanets much larger than our own - may actually be more like mini-Neptunes.
Astronomers believe they've worked out why there are so many fewer dwarf galaxies than predicted: they're moving so fast that their gas is simply whipped away.
