NASA scientists have taken a closer look at three Kuiper Belt objects to see whether they'll make good targets for the Pluto mission.
Astronomers are peering further and further afield, thanks in part to NASA's Kepler spacecraft. Now, scientists are using Hubble in order to study the exoplanets that Kepler identified, which could eventually lead to the discovery of life on other planets.
Astronomers have taken a look at our closest galactic neighbors, the dwarf spheroidal galaxies, and have found that they're devoid of star-forming gas--and our Milky Way may be to blame.
Scientists have used ESO and other telescopes in order to better understand the formation of one particular cluster: the Spiderweb Galaxy and its surroundings.
NASA's Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft has given scientists their very first look at the atmosphere of Mars.
Astronomers have decided to take a closer look at Venus to learn more about the planet. They're using a new optical device installed on the Italian National Telescope to measure Venus' precise gravitational pull on the sun.
Scientists have long wondered whether matter is falling into the massive black hole in the center of our Milky Way galaxy, or being ejected from it. Now, scientists are searching for an answer.
Where can you find the most methane emissions in the United States? Scientists may have found that out with the use of a new map. They've mapped satellite data in order to uncover the nation's largest methane signal seen from space.
Mars is going to get a spectacular show in the form of a comet. On Oct. 19, Comet Siding Spring will come within about 87,000 miles of Mars, which is about one-third of the distance of the moon from Earth.
Here on Earth, people are gearing up for Halloween by carving pumpkins into jack-o-lanterns and preparing their costumes. Now, it looks like the sun has also decided to show off just in time for the scariest night of the year.
Scientists have learned a bit more about how the universe evolved by studying leaky galaxies. They've taken a closer look at large star-forming galaxies to measure radiation leaks to see how the first stars were formed.
