ESA's billion-star surveyor Gaia, less than a week from launch, is now tucked up inside the fairing that will protect it during the first few minutes of ascent into space.
It turns out that Earth isn't the only place where you can find a molecule containing a noble gas. Using an instrument aboard Europe's Herschel Space Observatory, researchers have discovered a noble gas, argon hydride, in the Crab Nebula.
Determining the age of rocks is an important part of finding out more about a planet. That's why researchers have determined ages of rocks from planetary bodies in the past. Yet these experiments have always been conducted on Earth. Now, researchers have successfully determined the age of a Martian ...
It's the end of the universe as we know it--sort of. Physicists have long predicted that the universe may one day collapse and that everything within it will be compressed into a small, hard ball. Now, new calculations confirm this prediction and shows that the risk of collapse is actually greater t...
NASA is assessing a problem with one of two cooling systems aboard the International Space Station, a potentially serious but not life-threatening situation, officials said on Wednesday.
NASA's Hubble Space Telescope has made some surprising discoveries when it comes to Jupiter's moon, Europa. It's spotted water vapor above the moon's frigid south polar region, providing the first strong evidence of water plumes erupting off the moon's surface.
Atmospheric peculiarities similar to Earth and a few other planets may also be common to billion other planets and moons in the galaxy, researchers find.
A new, low-cost cubesat mission will demonstrate technology needed to measure the absolute imbalance in the Earth's radiation budget for the first time.
NASA's Juno spacecraft has made a spectacular recording of its flyby past Earth early in October 2013. The first-of-a-kind movie approach reveals the capabilities of Juno's onboard camera system, known as star tracker.
The data from NASA's Mars Curiosity rover is revealing new information each and every day. Now, scientists have shown that they've received the first detailed radiation measurements from the surface of the Red Planet.
After the Big Bang, our universe began to expand and emerge, forming stars, galaxies and planetary systems. Yet the specifics of this formation process have long remained a mystery to scientists. Now, researchers have taken a closer look at how the universe was formed.
It turns out that an atmospheric peculiarity that Earth shares with Jupiter, Saturn and Uranus may be more common than expected. Scientists have discovered that it's likely common to billions of planets, which may help in the search for potentially habitable worlds.
