NASA's Fermi Gamma-ray Telescope has uncovered some new information about two classes of black-hole-powered galaxies.
SPHERE, an instrument that's now mounted on the Very Large Telescope, is getting down to business. With its ability to use new, advanced techniques, it's showing astronomers more about nearby exoplanets, revealing a bit more about our universe.
NASA's Hubble Space Telescope has snapped a new, gorgeous image of the evolving universe. Using colorful images captured by the telescope over the past 24 years, astronomers have assembled a comprehensive picture.
One of the two newly discovered planets, circling an ancient star that is near to our own Sun, may have water on its surface, a new finding suggests.
Astronomers are learning a lot more about solar surges, thanks to the 1.6-meter telescope at Big Bear Solar Observatory (BBSO). The researchers have analyzed the highest-resolution solar observations ever made, revealing a lot more about our closest star.
Astronomers may have found two planets that could support life. They've spotted two new planets orbiting a very old star near to our sun, and one of them orbits just at the right distance to allow liquid water to exist on its surface--a key ingredient to support life.
Astronomers using the Chandra X-ray Observatory have caught a spectacular image revealing new details about violent collisions involving at least four clusters of galaxies.
How rare is life in our universe? It might just be far less likely than we once thought. Astronomers looking for habitable worlds have found that harsh space weather may doom life on planets near red dwarf stars.
Planets come in two different categories in our solar system, but there's also third category outside our system--planets that are about one to four times the size of Earth. Now, NASA's Kepler has learned a bit more about these categories.
A star is about to have a cosmic snack. Scientists have found the two worlds orbiting a distant star will be swallowed by the star in just a short period of time--at least by astronomical standards.
There's a new type of planet in our universe--and it's a big one. Astronomers have discovered a rocky world weighing 17 times as much as Earth, making it much larger than the previously-known "super-Earth."
NASA astronomers have caught a coronal mass ejection with the help of its newest solar observatory. Scientists can now study the ejection of solar particles with the Interface Region Imaging Spectrograph (IRIS) in extraordinary detail.
