Astronomers using a new instrument on the Very Large Telescope in Chile have directly imaged a newborn planet. Our understanding of planet formation is often shrouded in theoretical models. But now, scientists have directly observed a new planet in the gaseous disk around a young star about 370 light-years from Earth. The search for new…
Scientists have discovered that a supervolcano likely created a mysterious rock formation on Mars some 3 billion years ago.
New observations have helped astronomers identify the source of a 2,000-year-old supernova explosion. But this blast, and the neutron star that created it, seem to have a curious history that defies explanation.
The RXTE satellite, which reentered Earth's atmosphere over the tropics on April 30th, leaves behind a legacy of discoveries and data.
Curiosity spotted polygonal shapes on the surface of rocks on Mars — now, analysis of these mud cracks is revealing the history of the long-ago lake that once filled Gale Crater.
