"Tabby's Star" has dramatically dimmed. Something passed in front of it, dimming its starlight a whopping 20 percent and other jumbled transit signals revealed that something wasn't quite right with this particular star.
Mineral veins found in Mars's Gale Crater were formed by the evaporation of ancient Martian lakes, a new study has shown.
Researchers list exoplanets with the most potential to have liquid water, or even life. An international team of researchers has pinpointed which of the more than 4,000 exoplanets discovered by NASA
A major revision is required in our understanding of our Milky Way Galaxy. Astronomers have found that there is a huge region around the center of our own galaxy, which is devoid of young stars.
Richard Branson's dream of commercial space tourism is a step closer to reality. His Virgin Galactic company has been granted an operating licence by US aviation officials to fly passengers to the point of weightlessness.
In 2009 astronomers detected an unusual object, named CX330, as a source of X-rays as it was surveying the center of the Milky Way galaxy but they had not idea what it was. Today, astronomers have a better idea to what this strange object is.
Virgin Spaceship Unity, set to begin test flights next month, includes a very special nod to the theoretical physicist.
A NASA news release describes a recently published study which has found that Jupiter’s Great Red Spot appears to act as a heat source and is likely the reason behind the planet’s surprisingly high upper atmospheric temperatures.
New data from NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, has, for the first time, begun to pinpoint large numbers of the black holes sending out the high-energy X-rays.
SPACE tourism from Prestwick is a step closer after a US firm at the cutting edge of spaceflight design struck a deal with the Ayrshire base to bring manned launch services to Scotland.
The Large Underground Xenon (LUX) dark matter experiment, which operates beneath a mile of rock at the Sanford Underground Research Facility in the Black Hills of South Dakota, has completed its silent search for the missing matter of the universe.
Future tests will put the New Shepard spacecraft through more rigors before people fly aboard.
An international team of astronomers has discovered and confirmed a treasure trove of new worlds using NASA's Kepler spacecraft on its K2 mission.
That's galaxies, not stars. After spending a decade measuring the stars, scientists just released a 3D map spanning 1.2 million galaxies.
The Mars 2020 mission will look a lot like NASA's Mars Science Laboratory, but will feature some impressive tools to track down ancient life and do some important groundwork ahead of a future human mission.
