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.
NASA scientists and engineers are eyeing the construction of a manned outpost that would hover in orbit above the far side of the moon.
NASA’s Hubble Space Telescope has captured a sharp image of NGC 4634, a spiral galaxy seen exactly side-on.
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.
NASA's Mars rover Curiosity is taking a break from its drive to Glenelg to examine a football-size rock with its robotic arm.
NASA scientists are zapping organics with lasers in an attempt to discover how life arose on Earth.
A Starship Enterprise-style warp drive could be a real possibility, according to a non-profit group of scientists and engineers.
After four months aboard the International Space Station, three astronauts touched down safely in Kazakhstan early yesterday morning.
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 stalwart Opportunity rover has captured an image of the Martian surface that is puzzling scientists.
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 Dawn spacecraft has departed the giant asteroid Vesta, setting sail
for a two-and-a-half-year journey to the dwarf planet Ceres.
NASA's Dawn spacecraft remains on track to become the first probe to orbit and study two distant solar system locations.
The kids are in the back, there's gas in the tank, and NASA's Mars rover Curiosity has set off on its first long trip.
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.
