The first two full-resolution images of the Martian surface, from the Navigation cameras on NASA’s Curiosity rover, located on the rover’s “head” or mast. The rim of Gale Crater can be seen in the distance beyond the pebbly ground. Image Credit: NASA/JPL-Caltech
NASA’s Explorers Program FINESSE, proposed for launch in 2016, is the first mission dedicated to finding out what exoplanet atmospheres are made of and how our own solar system fits into the larger family of planets. Credit: NASA/JPL-Caltech
Galaxies with the most powerful, active, supermassive black holes at their cores produce fewer stars than galaxies with less ones. This is from new data from the Herschel Space Observatory. Image Credit: NASA/JPL-Caltech
This artist’s conception illustrates Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA’s Kepler mission has confirmed to orbit in a star’s habitable zone — the region around a star where liquid water, a requirement for life on Earth, could persist. The planet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habitable zone of a star like our sun.
