The Hubble Space Telescope has photographed the never-before-seen break-up of an asteroid, which...
Future lunar missions may be fueled by gas stations in space. According to engineers, a...
NASA is plotting a daring robotic mission to Jupiter's watery moon Europa, a place where astronomers speculate there might be some form of life.
Exposing leafy vegetables, grown during spaceflight, to a few bright pulses of light daily could increase the amount of eye-protecting nutrients produced by the plants.
Physics students have shown that humans could fly like birds on Saturn’s moon while wearing a wingsuit– provided they could get a run up of over 11 meters per second.
A giant sunspot– a magnetically strong and complex region on the sun's surface– has appeared over the sun's horizon. This is the third trip for this region across the face of the sun, which takes approximately 27 days to make a complete rotation.
In space, things don’t always behave the way we expect them to. In the case of cancer, researchers have found that this is a good thing: some tumors seem to be much less aggressive in the microgravity environment of space compared to their behavior on Earth.
The Global Precipitation Measurement Core Observatory, a joint Earth-observing mission between NASA and the Japan Aerospace Exploration Agency, has thundered into space from Japan.
After eight years of observations, scientists from the SETI Institute have found an exotic orbit for the largest Trojan asteroid, 624 Hektor— the only one known to possess a moon.
NASA could have prevented last summer's near-drowning of a spacewalking astronaut at the International Space Station, an investigation panel concluded this week.
A team of scientists has looked at how super-Earths form and suggest that many of them may be a lot less clement than was thought.
A human mission to Mars is both feasible and affordable assuming policy consistency among international space agencies and levels of funding consistent with pre-sequestration levels and modest increases annually in line with inflation.
Researchers are proposing an experiment that may close the last major loophole of John Bell’s inequality— a 50-year-old theorem that, if violated by experiments, would mean that our universe is based not on the textbook laws of classical physics, but on the less-tangible probabilities of quantum mechanics.
A new and powerful satellite has given researchers a way to see into the dark interiors of supernovae. Their observations of the supernova remnant Cassiopeia A shed light on the mechanics of these explosions.
A paper provides the first English translation and an analysis of one of Albert Einstein’s little-known papers, “On the cosmological problem of the general theory of relativity.” Published in 1931, it features a forgotten model of the universe, while refuting Einstein’s own earlier static model of 1917.
A new study shows what happens during the destruction of a star as it falls into a black hole, contradicting a 2012 report of the disruption of an exotic helium star.
An Expedition 38 crew member aboard the International Space Station took this photograph of Sochi Olympic Park at night.
Researchers have determined the now-infamous Martian rock resembling a jelly doughnut, dubbed Pinnacle Island, is a piece of a larger rock broken and moved by the wheel of NASA's Mars Exploration Rover Opportunity in early January.
Scientists are challenging our current understanding in a new study that combines observations of massively energetic cosmic ray particles streaming in from elsewhere in the Milky Way along with observations from NASA's Interstellar Boundary Explorer, or IBEX.
China has restored communications with its space program's troubled Jade Rabbit moon rover, but engineers are still working to fix its mechanical problems, according to state media.
Researchers are analyzing the new films captured by NASA's Cassini spacecraft and Hubble Space Telescope, which together provide a spectacular 360-degree view of Saturn’s auroras.
Spacecraft orbiting Mars have returned clues for understanding seasonal features that are the strongest indication of possible liquid water that may exist today on the Red Planet.
This photo captures the Curiosity Mars rover's view of the twilight sky and Martian horizon. It shows Earth as the brightest point of light in the night sky.
Scientists have solved a major problem with the current standard model of cosmology by combining results from the Planck spacecraft and measurements of gravitational lensing to deduce the mass of neutrinos.
There are few things as important on, and especially off, Earth as breathable, quality air. When air quality is compromised, we often don't have seconds to spare, which is why development of the Multi-gas Monitor is so important.
On Feb. 9, 1964, the Beatles made their U.S. debut on the Ed Sullivan Show. Now, 50 years later, an infographic follows those radio waves through space and time as they travel “across the universe” and beyond.
