| How Mars' atmosphere got so thin: Reports detail Curiosity clues to atmosphere's past Posted: 18 Jul 2013 11:30 AM PDT A pair of new papers report measurements of the Martian atmosphere's composition by NASA's Curiosity rover, providing evidence about loss of much of Mars' original atmosphere. |
| Snow in an infant solar system: A frosty landmark for planet and comet formation Posted: 18 Jul 2013 11:27 AM PDT A snow line has been imaged in a far-off infant solar system for the very first time. The snow line, located in the disc around the Sun-like star TW Hydrae, promises to tell us more about the formation of planets and comets, the factors that decide their composition, and the history of the Solar System. |
| MAVEN spectrometer opens window to Red Planet’s past Posted: 18 Jul 2013 10:10 AM PDT When NASA's MAVEN mission begins its journey to the Red Planet later this year, it will be equipped with a special instrument to take the planet back in time. |
| Hubble shows link between stars' ages and their orbits in dense cluster Posted: 18 Jul 2013 10:06 AM PDT Astronomers using NASA's Hubble Space Telescope have determined the orbital motion of two distinct populations of stars in an ancient globular star cluster, offering proof they formed at different times and providing a rare look back into the Milky Way galaxy's early days. |
| NASA interplanetary probes to take pictures of Earth Posted: 18 Jul 2013 10:03 AM PDT Two NASA spacecraft, one studying the Saturn system, the other observing Mercury, are maneuvering into place to take pictures of Earth on July 19 and 20. |
| Slow bow shock ahead of the sun's heliosphere predicted Posted: 18 Jul 2013 08:13 AM PDT A new study indicates that a bow shock (a dynamic boundary between sun's heliosphere and the interstellar medium) is highly likely. These findings challenge recent predictions that no such bow shock would be encountered. |
