| Spitzer Discovers Young Stars with a 'Hula Hoop' Posted: 31 Jul 2013 12:57 PM PDT Astronomers using NASA's Spitzer Space Telescope have spotted a young stellar system that "blinks" every 93 days. Called YLW 16A, the system likely consists of three developing stars, two of which are surrounded by a disk of material left over from the star-formation process. |
| NASA's Cassini sees forces controlling Enceladus jets Posted: 31 Jul 2013 12:53 PM PDT The intensity of the jets of water ice and organic particles that shoot out from Saturn's moon Enceladus depends on the moon's proximity to the ringed planet, according to data obtained by NASA's Cassini spacecraft. |
| Saturn's Mimas and Pandora: Two moons passing in the night Posted: 31 Jul 2013 08:30 AM PDT The Saturn moons Mimas and Pandora remind us of how different they are when they appear together, as in this image taken by NASA's Cassini spacecraft. Pandora's small size means that it lacks sufficient gravity to pull itself into a round shape like its larger sibling, Mimas. Researchers believe that the elongated shape of Pandora (50 miles, or 81 kilometers across) may hold clues to how it and other moons near Saturn's rings formed. |
