NASA has taken a closer look at the "teenage years" of quasars. Using the Hubble Space Telescope, astronomers have uncovered the early formative years of the brightest objects in the universe.
NASA's New Horizons spacecraft has beamed back the first ever color movies of Pluto and its largest moon, Charon. The new video reveals the complex dance of the two bodies, known as a double planet.
Scientists have uncovered some mysterious lakes on Saturn's moon, Titan. Now, they've taken a closer look at what causes the depressions on the surface and how they become filled with liquid hydrocarbons.
NASA's Cassini spacecraft has sent back some spectacular new images of Saturn's fracture-faced moon Dione.
Scientists may have discovered lava flows on the surface of Venus. ESA's Venus Express has revealed the best evidence yet for active volcanism on the planet.
Using the Hubble Space Telescope's infrared vision, astronomers have unveiled some of the previously hidden origins of quasars, the brightest objects in the universe.
Supermassive black holes can be found at the centers of every large galaxy. Now, ALMA has managed to "weigh" one of these supermassive black holes.
The Hubble Space Telescope has spotted a bizarre cosmic quartet. It's viewed a galaxy group bursting with dramatic star formation, tidal tails, galactic mergers and black holes.
Saturn's moon, Titan, may have an atmosphere that's far more Earth-like than once thought.
Scientists may have discovered a region of space where stars collide. They've found a cluster of stars that are so densely packed that it's likely that they may collide in the future.
You might be surprised to learn that the sun's atmosphere is actually hotter than its surface. Now, scientists may have found out why this is.
Our moon may actually have clouds. Scientists have discovered that the moon is engulfed in a permanent-but lopsided-dust cloud that increases in density when annual events like the Geminids spew shooting stars.
