How does living in an endless ocean sound? For some, a perpetual sea-side view may be a dream come true. And that dream may already be a reality for extraterrestrial life, according to a new study which suggests that watery exoplanets tilted on their axis in just the right way would boast a "rather mild" and habitable climate.
The holidays this time of year always seems to make night a little brighter. Now NASA and the NOAA have released evidence that during December, cities especially in the United States shine up to a whopping 50 percent brighter - a change best seen from space.
It appears that Mercury, the closet planet to the Sun, is being bombarded by a meteor shower, according to recent research.
Late last month, the European Space Agency's (ESA) unmanned orbiter Venus Express slipped into the incredibly dense atmosphere of Earth's "sister planet," never to be heard from again. Now experts have confirmed from telemetry just before its disappearance that the probe is likely out of fuel and will be unable to make contact with Earth ever again.
Mars is a dead world. It may have once been home to water and life, but experts have been fairly certain that the Red Planet is now nothing more than a grave frozen in time - a snapshot of what would happen to Earth if it was ever stripped of its atmospheric protections. However, new data from NASA's Curiosity rover has revealed that the planet is still a bit active, at least on a chemical level.
Mars is home to the largest known canyon system in our solar system, and while the jury is still out on what exactly formed these canyons - be it water or lava - we do finally know what helped form the unusually hilly geological formations that can be found in their depths.
An entire family of Pluto-sized protoplanets may be swarming around a young star known as HD 107146, an adolescent version of our own Sun, a new study says.
A number of holidays are nearly upon us, and you neighborhood is likely looking a lot brighter at night. Little did you know that up above, the Universe has brightened as well. That's because a pair of Galaxies about 130 million light years away just had a get-together, producing some of the most concentrated super-bright X-ray light emissions ever seen.
An analysis of water vapors from comet 67P/Churyumov-Gerasimenko, the quarry of the Rosetta Spacecraft and its history-making Philae lander, has revealed that its water is not at all like Earth's. This revelation casts some serious doubt on one theory of how our oceans formed, and raises many new questions.
You may have seen some headlines this week like "Mountain-Sized Asteroid is Heading for Earth!" or "Dangerous Asteroid Headed our Way," but you shouldn't trust the hype. According to NASA's Near-Earth Object Program (NEOP) office, that huge asteroid heading our way isn't even close to being a threat.
It used to be that we knew so little about the microgravity of space that we'd send dogs up in pressurized cabins just to see how they fared. Now, we know enough to the point where we are actually using space as ideal conditions for medical research, exposing secrets of the human immune system.
The mystery of Titan's windswept dunes is finally solved, thanks to a research team at the University of Tennessee, a new study says.
NASA's Curiosity Rover found clues of an ancient lake on Mars, shedding light on how water shaped this Martian landscape, new research explains.
NASA's Dawn spacecraft has the protoplanet Ceres in its sight, and soon will have a close encounter with this unusual alien world. Still, before Dawn get's there, it may help to answer some questions such as "what exactly is Ceres?"
When you think of stars, you likely think of incredibly hot balls of blazing fire and writhing plasma. However, experts have long known that for a new star to be born, a stellar nursery actually needs some cool conditions. Now, astronomers have observed how a wave of hot gas can extinguish star formation entirely, exposing new secrets of the Universe.
