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.
Our moon may hold more secrets than we first thought. Researchers have discovered some mineralogical surprises in the moon's largest impact crater, revealing a bit more about its mantle.
For all the enthusiastic space lovers, NASA offers another chance have some cosmic fun. The Geminid meteor showers are going to make its annual appearance and put up some spectacular cosmic fireworks, just in time for Christmas.
Astronomers have captured new and surprising details of a nearby starburst galaxy. Using the Green Bank Telescope (GBT), the scientists have uncovered never-before-seen features, such as streamers of material fleeing the disk of the galaxy as well as concentrations of dense molecular gas surrounding...
