The most detailed record of cloud motion in the atmosphere of Venus has revealed that the planet’s winds have steadily been getting faster over the last six years.
NASA announced a Grand Challenge focused on finding all asteroid threats to human populations and knowing what to do about them.
Europe has never been more active in space, with a crowded manifest of ESA launches across the rest of the year. But where are all these varied missions born? See for yourself this October.
Researchers are examining strange features on Mars. They're called, "linear gullies," because they're long troughs. They can extend up to two kilometers and they're strange because they go down slopes and then end abruptly in a pit.
Milky Way's galactic neighbor, Andromeda. This is the largest number of possible black holes found in a galaxy outside of our own.
Astronomers using the Swiss 1.2-meter Euler telescope have found a new type of variable star.
Researchers have discovered high concentrations of boron in a Martian meteorite. When present in its oxidized form, boron may have played a key role in the formation of RNA, one of the building blocks for life.
Space scientists report that data gathered by NASA’s Lunar Reconnaissance Orbiter (LRO) show lighter materials like plastics provide effective shielding against the radiation hazards faced by astronauts during extended space travel.
The least massive galaxy in the known universe has been measured, clocking in at just 1,000 or so stars with a bit of dark matter holding them together. The findings offer tantalizing clues about how iron, carbon and other elements key to human life originally formed.
Approaching its 10th anniversary of leaving Earth, NASA's Mars Exploration Rover Opportunity is on the move again, trekking to a new study area still many weeks away.
Astronomers have imaged a region around a young star where dust particles can grow by clumping together. This is the first time that such a dust trap has been clearly observed and modeled.
June began with a gorgeous trio of planets: Mercury, Venus and Jupiter, low on the west-northwest horizon. As the month progresses, Jupiter slips into the sunset while Mercury and Venus rise higher in the sky.
Scientists using the most powerful telescope on Earth have discovered the moments just after the Big Bang happened more like the theory predicts, eliminating a significant discrepancy that troubled physicists for two decades.
In lieu of a time machine, we learn about the birth of our sun and its planets by studying young stars in our galaxy. New work suggests that our sun was both active and "feisty" in its infancy.
A bright dwarf galaxy, which is relatively close to Earth’s Milky Way and trailing fireballs, is the first clear example of a galaxy in the act of dying.
The cores of black holes may not hold points of infinite density as currently thought, but portals to elsewhere in the universe.
Scientists may not know for certain whether life exists in outer space, but new research shows that one key element that produced life on Earth was carried here on meteorites.
New global maps of Mars released on the 10th anniversary of the launch of ESA’s Mars Express trace the history of water and volcanic activity on the Red Planet, and identify sites of special interest for the next generation of Mars explorers.
NASA's Hubble Space Telescope will have two opportunities in the next few years to hunt for Earth-sized planets around the red dwarf Proxima Centauri.
NASA will launch a new set of eyes to offer the most detailed look ever at the sun’s lower atmosphere, called the interface region.
Astronauts traveling to and from Mars would be bombarded with as much cosmic radiation as they’d get from having a full-body CT scan once a week for a year.
GRAIL has uncovered the origin of massive invisible regions that make the moon's gravity uneven, a phenomenon that affects the operations of lunar-orbiting spacecraft.
Researchers have taken a significant step in a project to unravel the secrets of the structure of our Universe.
A chemical reaction between iron-containing minerals and water may produce enough hydrogen “food” to sustain microbial communities living in pores and cracks within the enormous volume of rock below the ocean floor, parts of the continents and possibly Mars.
Researchers are helping NASA use the weightlessness of space to design stronger materials here on Earth.
