Although the life-threatening situation Gravity depicts is fictional, the new film faithfully captures the beauty of orbit, says a former space station crew member
The Fermi Gamma-Ray Space Telescope team is considering a new observing strategy that would focus on the center of the galaxy
NASA calls for rover instrument proposals, but some resent the space lost to storage of samples for retrieval by an unspecified future mission
Friction is both the boon and the bane of our everyday lives. It’s the force that drags against your car’s tires, making you use more gas to keep going.
Although a broken reaction wheel on NASA's Kepler spacecraft is bad news for its primary exoplanet-hunting mission, the glitch could be a boon for the study of stellar physics
Despite dozens of measurements over more than 200 years, we still don’t know how strong gravity is
After much debate over the murky boundary of interstellar space, a solar eruption gives scientists the evidence to say Voyager 1 has finally crossed it
The big bang should have distributed matter evenly throughout the universe. So why is there a big dense spot?
An unmanned rocket carrying $200 million in satellite technology likely crashed due to an emergency booster shutdown
NASA reaches out to the public for ideas on how to prevent dangerous asteroid impacts
A call for NASA's Fermi Gamma-Ray Space Telescope to focus on the center of the galaxy could clear up the identity of dark matter
Using a machine that creates beams of radioactive atomic nuclei, CERN physicists found the ionization potential of astatine
A Jupiter-like gas giant, 335 light-years from Earth, is caught in the process of formation by the European Southern Observatory's Very Large Telescope in Chile
Beneath its pretty pink exterior, Messier 106 harbors a monster black hole that gobbles up matter at the galaxy’s center
Scientists have altered the criteria for the habitable zone—an area not too close or far away from a star—taking into account whether planets can host liquid water. This redefines where researchers believe life-forms could exist...
Balloon-borne instruments in Antarctica often fall in the first few weeks, but the Super-TIGER balloon has been airborne for 46 days, shattering a previous record of just 42 days
Recent findings back up Einstein's thinking and cast doubt on "rolling scalar fields," an alternative theory of dark energy that suggests the accelerated expansion of the universe will change over time...
The fabled spaceship could join the similarly petitioned Death Star. Artificial gravity remains a big hurdle
Host of popular BBC program The Sky at Night for 55 years, Moore inspired many but was sometimes a divisive figure as well
Government satellites may start to hitch rides with commercial spacecraft in Earth orbit
