A parade of asteroids that struck our planet 4.5 billion years ago created an ancient hell on Earth, reshaping the surface and altering its topography, according to a team of researchers.
Researchers explain why moon has an odd shape.
A very strong but incredibly brief radio wave burst was first detected in 2007 by astronomers in Australia. Now, researchers half-a-world away have detected a burst of the exact same signature, showing that the first mysterious blast was not an instrument malfunction. However, no one has any idea what is behind this phenomenon.
Astronauts aboard the International Space Station finally flight tested their prototype flying robot assistants last Friday, setting the stage for an international robot programming competition that is slated to officially begin this fall.
In a series of trials aboard the International Space Station (ISS), researchers discovered a new type of cool burning flames that could lead to cleaner, more efficient engines for cars here on Earth, they reported in a new study.
This past weekend, NASA's 2004 Mars Exploration Rover, Opportunity, accrued more than 25 miles of total driving the Red Planet, breaking a record previous held by the Soviet Union's Lunokhod 2 Moon rover.
NASA's Cassini spacecraft has identified 101 geysers of water vapor and ice particles dotting the surface of Enceladus, one of Saturn's many moons.
A comet is due to hurtle by Mars at incredible speeds in the near future, and NASA has to make preparations so that the Red Planet's orbiting spacecraft do not find themselves being pummeled by bullets of ice and stone.
Looking for a reason to spend this weekend staring at the night sky? There's no better than the Delta Aquarids meteor shower.
The Hubble Space Telescope recently mapped the mass within a galaxy cluster more precisely than ever before, according to new research.
Earlier this month, NASA's Jet Propulsion Laboratory (JPL) confirmed that the unmanned spacecraft Voyager1 has slipped into interstellar space - a first for a manmade observational tool. However, researchers are now refuting this claim, saying that we won't truly know if this spacecraft has gone interstellar until late 2015.
Russia's Federal Space Agency (Roscosmos) has still not regained control of the unmanned Foton-M4, a biosatellite that is refusing to communicate with mission control. Experts do report that the five geckos onboard are doing fine and are likely to start "getting busy," unaware that anything is the matter.
NASA knows exactly how large a new "super Earth" exoplanet is, thanks to a combined effort from the Kepler and Spitzer Space Telescopes. This, according to NASA, is the most accurate measurement of this kind of exoplanet ever taken, and marks a new step towards better understanding these planetary bodies.
Experts have been using NASA's Hubble Space Telescope to take closer looks at potentially Earth-like exoplanets. But in searching for traces of water vapor, they've come up dry.
Researchers are using pollution to help in their search for alien life on other worlds, as described in a study published in The Astrophysical Journal. By observing exoplanet atmospheres, scientists can look for gases like oxygen and methane that only coexist if replenished by life.
