With the use of seven telescopes spread across South America, observers have confirmed the unlikely discovery of a double ring surrounding the minor planet Chariklo, which holds orbit between Saturn and Uranus. Previously rings have only been found around giant planets, the most dramatic of which, Saturn, shines easily visible to the naked eye in the night sky.  Read More

The intensity of the asteroid's impact on the lunar surface was sufficient to be seen with...

A meter-wide (3 ft) asteroid impacted the Moon's surface September 11, 2013, producing a bright explosion and digging a new crater about 40 meters (130 ft) in diameter. The video of the event shows a bright flash of light against the stark blackness of the Moon's dark side. Similar in brilliance to the brightest stars in the Big Dipper, the asteroid impact is the largest confirmed impact on the Moon since continuous monitoring started some 15 years ago.  Read More

In mid-2015, the asteroid probe Dawn is scheduled to establish orbit around Ceres, the only dwarf planet in the inner Solar System, as well as the largest asteroid, to begin roughly six months of close-up observation. The level of interest in this mission has significantly increased with the detection by the ESA's Herschel space observatory of plumes of water vapor being exuded from Ceres' surface from a pair of local sources.  Read More

Like nervous parents, scientists and engineers at ESA are pacing the floor of mission control as they await word of whether or not the Rosetta spacecraft has survived 31 months of hibernation. The unmanned comet chaser was scheduled to reactivate itself today at 10:00 GMT, but the time required to complete the operation and the distance a radio signal must travel back to Earth means that the space agency will not know until at least 17:30 GMT if the probe is operating again or has become deep space scrap.  Read More

NASA's Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) may have only come back online last September after a 31-month hibernation, but it’s already producing results. According to the space agency, the unmanned spacecraft discovered a never-before-seen asteroid on December 29 – the first discovery of its new mission to seek out potentially hazardous near-Earth objects (NEOs).  Read More

Earth saw in the New Year with some celestial fireworks as the first asteroid to be discovered this year, 2014AA, likely impacted the Earth between 7 pm Wednesday and 2 pm Thursday GMT.  Read More

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer (NEOWISE) has sent back the first test images from its 16-in (40-cm) telescope and infrared cameras as it is prepared for its new mission. Intended to seek out potentially dangerous asteroids and help in selecting a near-Earth object as part of the space agency’s asteroid retrieval effort, NASA says NEOWISE will be a powerful tool for discovering, cataloging and understanding the asteroids in the inner Solar System.  Read More

Sometimes you have to take a step back to take a step forward. NASA is carrying out initial tests on a new, lighter spacesuit for use by the crew of the Orion spacecraft that is currently under development. The tests are being carried out in the Neutral Buoyancy Laboratory near the Johnson Space Center in Houston, Texas on a modified version of the pumpkin orange suit normally worn by Space Shuttle crews during liftoff and re-entry and is a return to a space suit design of the 1960s.  Read More

We are continually being surprised by new discoveries of near-Earth asteroids and comets, often noticing them only after they have completed a close approach. Only one asteroid has ever been found and projected to impact prior to its actually doing so. With that in mind, NASA, Planetary Resources, and Zooniverse have formed a collaboration to use citizen scientists to detect members of the vast swarm of near-Earth objects not yet recognized or mapped.  Read More

P/2013 P5 is an asteroid with six comet-like tails (Image: NASA, ESA, and D. Jewitt)

In the old days, astronomy was simple – comets had tails and asteroids didn’t. Now, as if to not only disprove such established views, but drive the point home, NASA's Hubble Space Telescope took images in September of an asteroid called P/2013 P5 that has not one, but six comet-like tails.  Read More
