Using ground-based and space-based observations, a team of researchers has been monitoring a difficult-to-see comet carefully. It's called Comet 323P/SOHO, and it was discovered over 20 years ago in 1999. But it's difficult ...
An ultraviolet spectrograph (UVS) designed and built by Southwest Research Institute (SwRI) is the first scientific instrument to be delivered for integration onto NASA's Europa Clipper spacecraft. Scheduled to launch in ...
Trying to piece together the appearance of life on Earth is a little like looking through a kaleidoscope. There are competing theories for where Earth's water came from, and there's incomplete evidence for how the moon formed ...
Pictures of the Milky Way show billions of stars arranged in a spiral pattern radiating out from the center, with illuminated gas in between. But our eyes can only glimpse the surface of what holds our galaxy together. About ...
Object 90377 Sedna—a distant trans-Neptunian object known best for its highly elliptical, 11,390-year long orbit—is currently on its way toward perihelion (its closest approach to the sun) in 2076. After that, Sedna will ...
Astronomers have managed to link the properties of the inner planets of our solar system with our cosmic history: with the emergence of ring structures in the swirling disk of gas and dust in which these planets were formed. ...
Just two weeks after launching from Vandenberg Space Force Base in California, NASA's Double Asteroid Redirection Test (DART) spacecraft has opened its "eye" and returned its first images from space—a major operational milestone ...
Every so often, the Kuiper Belt and Oort Cloud throw galactic snowballs made up of ice, dust and rocks our way: 4.6-billion-year-old leftovers from the formation of the solar system.
Scientists have unraveled a fascinating new insight into how the landscape of the dwarf-planet Pluto has formed.
As the new space race continues, a team of top researchers says one thing needs to be cleared up—what exactly is a planet?
