“Centaurs can be considered as some of the leftovers of our planetary system’s formation. Because they are stored at very cold temperatures, they preserve information about volatiles in the early stages of the solar system,” said Sara Faggi of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and American University in Washington, DC, lead author … Read more
NASA’s near-Earth-object-hunting mission NEOWISE is nearing its conclusion. But its work will carry on with NASA’s next-generation infrared mission: NEO Surveyor. After more than 14 successful years in space, NASA’s NEOWISE (Near-Earth Object Wide-field Infrared Survey Explorer) mission will end on July 31. But while the mission draws to a close, another is taking shape, … Read more
As the infrared space telescope continues its long-duration survey of the universe, it is creating a unique resource for future astronomers to make new discoveries. NASA’s NEOWISE mission has released its 10th year of infrared data – the latest in a unique long-duration (or “time-domain”) survey that captures how celestial objects change over long periods. … Read more

SOHO has achieved this milestone … Read more
The asteroid and comet-hunting infrared space telescope has gathered an impressive haul of observations, but it’s now at the mercy of the Sun, which is accelerating its demise. NASA’s NEOWISE has had a busy decade. Since its reactivated mission began on Dec. 13, 2013, the space telescope has discovered a once-in-a-lifetime comet, observed more than … Read more
The asteroid is expected to reach its closest point to Earth on March 4 at 2:59 am Eastern Time. An asteroid termed as “potentially hazardous” by astronomers is relatively close, but safe, and is soon approaching Earth next week. The asteroid, space rock, called 138971 (2001 CB21) is estimated to be up to 3,940 feet … Read more
Comet ISON had been discovered in September 2012. Hubble Space Telescope: NASA releases time-lapse sequence of Comet ISON’s movement captured by Hubble Space Telescope! On Tuesday, the US space agency NASA released a time-lapse video of the Comet ISON moving against the stars. The video was made based on images captured by the Hubble Space … Read more
