The Chinese space program has hit a new milestone. A Chinese spacecraft service module has entered orbit around the moon.
Scientists have examined these biological effects a bit more closely and have found that in space, the shift of blood and fluid from the lower to the upper body caused by weightlessness is much higher and that blood pressure is much lower than previously thought.
Astronomers may have succeeding in measuring the space-time warp in the gravity of a binary star. They've managed to determine the mass of a neutron star just before it vanished from view in a race against time.
Citizen scientists are making more and more discoveries each day. Now, a NASA-sponsored website designed to crowdsource analysis of data from the agency's Wide-field Infrared Survey Explorer (WISE) mission has reached a new milestone.
The Dawn spacecraft has snapped its best and most detailed picture yet of Ceres, the largest body in the main asteroid belt.
The Royal Observatory Greenwich and BBC's Sky at Night magazine hold a contest each year for the most amazing astronomy photos.
Space debris is starting to be a huge problem for satellites orbiting Earth. Now, it turns out that the Suomi NPP satellite experienced a near-miss when it comes to avoiding space trash in Earth's orbit.
Imagine being in space. Now, imagine that instead of a bulky spacesuit, you can put on a skintight, stretchy garment lined with tiny, musclelike coils.
Seven tiny grains of dust captured by the NASA Stardust spacecraft may just be from interstellar space.
Could there actually be water on the surface of Mars? It's possible, according to a new study.
Astronomers have accomplished a startling feat by using the AKARI orbiting observatory. They've created the first large-scale maps of ice material where stars are forming, challenging the conventional ideas about how water forms in space.
NASA successfully transmitted a 175-megabit video from the International Space Station to Earth on Thursday using the Optical Payload for Lasercomm Science (OPALS). This could revolutionize the way NASA receives data from space.
