Scientists are learning a little bit more about the asteroid, Vesta, and its internal structure. With the help of numerical simulations and data from the space mission Dawn, researchers have taken a closer look at its internal structure.
NASA Mars Curiosity rover continues its trek across the Red Planet, continually making new discoveries. Now, the rover has spotted a massive iron meteorite called "Lebanon" and has snapped a photo of the rock to send back to Earth.
Scientists have created the most detailed map of Mars to date. The U.S. Geological Survey has released a new global geological map of the Red Planet that reveals the startling features of the planet's surface.
The latest images captured by Europe's comet chaser Rosetta reveals that the nucleus of the 4 km-wide target comet is an irregularly shaped body.
NASA plans to sends its Multiple Altimeter Beam Experimental Lidar (MABEL) above Alaska and the Arctic Ocean on one of theER-2 high-altitude aircraft in order to investigate the features of the Arctic ice during the summer.
NASA's Landsat 8 doesn't just look down at Earth; it also looks to the moon. Now, after this past weekend's full moon, Landsat 8 has used the moon's light to perform some crucial tests.
Astronomers have made an extraordinary discovery and have learned a bit more about our universe's earliest stars because of it.
NASA's Mars Reconnaissance Orbiter (MRO) has made some new discoveries when it comes to the gullies on Mars' surface.
Astronomers have uncovered seven new dwarf galaxies while probing a nearby spiral galaxy. Using a new type of telescope, the researchers' finds may yield important insights into dark matter and galaxy evolution.
How old are sun-like stars? That's a good question, and it's one that astronomers have been struggling with for quite some time. Now, scientists have a new technique for measuring the age of a star by using its spin.
The NASA Hubble Space Telescope has made an unusual discovery. It's taken a snapshot of two elliptical galaxies merging into one while a "chain" of young, stellar superclusters wind around the galaxies' nuclei.
