The mystery object discovered earlier this year travelling through our solar system is showing no signs of any alien life, despite plenty of efforts to look and listen for a signal.
It came from outer space … and went back there two weeks later, having astonished and excited astronomers and planetary scientists. A cigar-shaped object, less than half a kilometre long and barely bright enough to be detected ...
When comet 45P zipped past Earth early in 2017, researchers observing from NASA's Infrared Telescope Facility, or IRTF, in Hawai'i gave the long-time trekker a thorough astronomical checkup. The results help fill in crucial ...
Comets are our most direct link to the earliest stages of the formation and evolution of the solar system. Only every few years is a new comet discovered that is making its first trip to the inner solar system from the Oort ...
The astronomy world has been abuzz recently with the discovery of a new object cutting through our solar system. Its path indicates it came from interstellar space—the first body of its kind ever observed.
The discovery of an unusual small object in the solar system last month caught the imagination of the global astronomical community. Scientists around the world were asking "what is it?" and "where did it come from?"
A team of astronomers led by UCLA professor David Jewitt has identified a "special comet" 1.5 billion miles from the sun. No other comet heading toward our sun has ever been seen at such a great distance.
Mercury, our smallest planetary neighbor, has very little to call an atmosphere, but it does have a strange weather pattern: morning micro-meteor showers.
NASA's Hubble Space Telescope has photographed the farthest active inbound comet ever seen, at a whopping distance of 1.5 billion miles from the Sun (beyond Saturn's orbit). Slightly warmed by the remote Sun, it has already ...
During almost four years of observing the cosmos, the Herschel Space Observatory traced out the presence of water. With its unprecedented sensitivity and spectral resolution at key wavelengths, Herschel revealed this crucial ...
