Our Milky Way Galaxy is surrounded by an enormous halo of hot gas hundreds of thousands of light years across, and with as much mass as all the stars in the galaxy.
Recent images snapped by NASA's Dawn spacecraft confirm that volatile, or easily evaporated materials, have colored Vesta's surface in a broad swath around its equator.
Astronomers have, for the first time, spotted planets orbiting sun-like stars in a crowded cluster - the best evidence yet that planets can form in dense stellar environments.
NASA’s Hubble Space Telescope has captured an image of galaxy NGC 7090. The galaxy is viewed edge-on from the Earth, meaning astronomers are unable to easily see the spiral arms, which are full of young, hot stars.
NASA's three stalwart mobile launcher platforms (MLP) are currently being revamped to better accommodate the space agency's next-generation launch vehicles.
NASA scientists will next week test whether a heat shield made from the soil of the moon, Mars or an asteroid could stand up to a plunge through Earth's atmosphere.
NASA’s Mars Curiosity rover has completed the delicate calibration of a robotic arm as it awaits further instructions in Gale Crater near the Martian equator.
NASA's Mars Reconnaissance Orbiter (MRO) has returned the first definitive evidence of carbon dioxide snowfalls on Mars - the only place this is known to happen anywhere in our solar system.
NASA's Mars Curiosity rover recently concluded a series of preparatory tests designed to calibrate precision movements by the rover's robotic arm which is used to deploy a wide variety of tools.
NASA's Kepler mission has for the first time discovered multiple planets orbiting a pair of stars, showing it's possible for more than one planet to be formed and survive in such a chaotic environment.
