View of a particle plume erupting from the surface of Bennu, as seen by OSIRIS-REx on Jan. 19, 2019. This is the first time that such plumes have ever been observed on an asteroid. Photo Credit: NASA/Goddard/University of Arizona/Lockheed Martin Close-up observations of the near-Earth asteroid Bennu have revealed many surprises, NASA announced today […] 
Artist’s conception of the InSight lander on Mars. The SEIS instrument is the dome-shaped object in the foreground. Image Credit: NASA/JPL-Caltech One of the science instruments being installed on the InSight lander is experiencing a vacuum leak, according to an update posted Dec. 3 on the JPL website. The leak is in the […] 
The unusual grooves on Phobos’ surface, such as those on the left side of this image, are now thought to be caused by tidal stress. The large crater Stickney is in the upper portion of the image. Image Credit: NASA/JPL-Caltech/University of Arizona Phobos is the largest of Mars’ two tiny moons, but 50 […] 
View of Enceladus and Saturn’s rings during the flyby on Oct. 28, 2015, at a distance of 106,000 miles (171,000 kilometers) from Enceladus. Image Credit: NASA/JPL-Caltech/Space Science Institute The Cassini spacecraft has successfully completed its deepest dive through the water vapor geysers of Enceladus and is now sending back some fantastic images of […] 
Artist’s conception of Cassini making a close flyby of Enceladus and its water vapor plumes. Image Credit: NASA/JPL This coming Wednesday, Oct. 28, 2015, the Cassini spacecraft will make a historic close flyby (dubbed “E21”) of Saturn’s tiny icy moon Enceladus, not only passing very close to the surface, but also making the […] 
New high-resolution view of the north polar region on Enceladus, showing a cratered surface crisscrossed by many cracks. Image Credit: NASA/JPL-Caltech/Space Science Institute The Cassini spacecraft has just successfully completed the first of three final close flybys of Saturn’s moon Enceladus, and has sent back some spectacular images of the northern regions of […] 
Illustration of Cassini’s “E-20” flyby of Enceladus, which will provide new, detailed views of the moon’s north polar region. Image Credit: NASA/JPL-Caltech Starting today, the Cassini spacecraft is making the first of three scheduled close flybys of the moon Enceladus, which will provide the first good look at the north polar region of […] 
Diagram depicting the interior of Enceladus, with the global ocean between the ice crust above and the rocky core below. The jets of water vapor erupt from fissures at the south pole. Image Credit: NASA/JPL-Caltech Along with Jupiter’s moon Europa, Saturn’s moon Enceladus is considered to be one of the best places to […] 
New color images of Pluto sent back by New Horizons showing two different “faces” or hemispheres of the dwarf planet and its largest moon Charon. Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute First there were the unusual bright spots on Ceres, which are still awaiting an explanation, and now as […] Artist’s conception of an ocean-covered aquaplanet. Image Credit: Christine Daniloff/MIT With so many exoplanets now being discovered on a regular basis by astronomers, the focus has turned to what number of them might be habitable for some kind of life. For life as we know it at least, that depends on a number […] |
