Just over a month ago the European Space Agency’s Rosetta spacecraft finished its mission by spectacularly diving into the comet 67P/Churyumov-Gerasimenko. How did it observations influence and alter our ideas about the typical formation and lifetime of a comet?
At this year’s Division for Planetary Sciences/European Planetary Science Congress meeting, the Exoplanet Dynamics session was packed full of talks on tightly-packed multi-planet systems and their instabilities.
The third-largest object known beyond Neptune, 2007 OR10, has a moon. The discovery was reported in a poster by Gábor Marton, Csaba Kiss, and Thomas Mueller at the joint meeting of the European Planetary Science Congress and the Division for Planetary Sciences of the American Astronomical Society (DPS/EPSC) on Monday.
Science in America depends on federal funding, yet many young scientists don't understand how the U.S. government decides to spend its money on science, nor are they encouraged to use their new degrees to advise the process. This is changing with support from the American Association for the Advancement of Science.
At last week's Lunar and Planetary Science Conference, I enjoyed a large number of talks about Ceres. Now in its Low-Altitude Mapping Orbit, Dawn is showering scientists with high-resolution, color data.
The Division of Planetary Science (DPS) Meeting saw many exciting scientific discussions spanning the range of processes on different planetary bodies, as well as their replication in the laboratory and in models.
Pluto is reluctant to give up its secrets. Last week at the American Geophysical Union meeting I attended sessions featuring results from the New Horizons mission, and most of the presentations could be summed up thusly: the data sets are terrific, but there are still a lot of Pluto features that have scientists scratching their heads.
Yesterday at the American Geophysical Union meeting, the Curiosity science team announced the discovery of a mineral never before found on Mars. The finding was the result of a fortuitous series of events, but as long as Curiosity's instruments continue to function well, it's the kind of discovery that Curiosity should now be able to repeat.
