Fall Science Preview: So Much Science is Headed Right for Us!

‘Tis the season for dwarf planets with an impending flood of Pluto flyby data and Dawn just about to point its spectrometer at the weird white spots on Ceres. Add in ocean floor explorations, a pair of weights in perpetual free-fall, and a rash of rocket launches and we just know this year is going out in a bang of… » 8/26/15 4:45pm Wednesday 4:45pm

Beautiful New Topographical Map Of Ceres Shows a Complex, Icy World 

NASA has just released a stunning new topographic map of Ceres, the other dwarf planet astronomers are getting to study up close and personal this summer. Unlike Pluto’s freakishly smooth and youthful surface, Ceres’s exterior is riddled with craters, creating a battered old landscape of peaks and valleys. » 7/28/15 4:00pm 7/28/15 4:00pm

When We Discovered Pluto, It Changed How We Saw The Solar System

On the 23rd and 24th of January, 1930, a young astronomer working in Flagstaff, Arizona, scanned a small patch of the night sky. He was taking pictures of star positions, looking for anomalies that would signal movement somewhere at the edge of the solar system. He took the pictures then set them aside, not realizing… » 7/12/15 4:25pm 7/12/15 4:25pm

The Long, Spiraling Path NASA's Dawn Spacecraft Will Take to Ceres

Over the next few months, NASA's Dawn spacecraft will be slowly spiraling down toward Ceres, a dwarf planet out in the asteroid belt. Ceres' gravity and Dawn's ion drive will work together to pull the spacecraft into a tighter and tighter orbit, which is rather mesmerizing traced out in full like this. » 2/06/15 5:00pm 2/06/15 5:00pm

This Is The Greatest View Of Dwarf Planet Ceres We Have Ever Seen

The Dawn spacecraft has done it: it is now taking the highest-resolution images of the dwarf planet Ceres that have ever been seen. Not only is this new image better than the historic Hubble Space Telescope image, but every new release will be better than the one before until it arrives in orbit this March. » 1/28/15 2:15pm 1/28/15 2:15pm
