Opportunity From Above

Image

NASA’s Opportunity rover stands watch over Victoria Crater in this image taken by the Mars Reconnaissance Orbiter (MRO). This view, snapped in October 2006, offered the public a taste of what NASA’s Mars probe would eventually deliver.

The 0.5-mile-wide (800 meters) impact scar is just south of Mars’ equator. Erosion and rock slides there created Victoria’s distinctive scalloped rim. Those layered sedimentary rocks lie exposed along the crater’s inner wall, and fallen boulders dot the wall’s base. A striking field of sand dunes dominates the crater’s floor.

MRO took this image from an altitude of 166 miles (267 km), revealing objects as small as 32 inches (81 cm) across.

20 new moons discovered orbiting Saturn

Saturn now has 82 moons, knocking Jupiter down to second place in the moon count.

Image

Astronomers have found 20 new moons orbiting Saturn, bumping its total up to 82 moons. That surpasses Jupiter, which was the prior reigning champion with 79 moons.

One of the new moons has the farthest known orbit around Saturn, and all are similar in size, with diameters around three miles (5 kilometers). Two of the moons take about two years to orbit, while the other 18 take more than three years to do so.

Seventeen of the new moons orbit Saturn backward — or in retrograde — compared to the planet's other natural satellites. The retrograde moons have orbits resembling some of Saturn's other already-known moons. And by looking at their inclinations, astronomers suspect these moons could have been part of a much larger moon that broke apart long ago.

The moons were discovered by a team led by Scott S. Sheppard at the Carnegie Institution for Science and using the Subaru Telescope on Hawaii’s Mauna Kea.

Sorry no spectacular pics, but here's a lot of interesting information about the recent Saturn's moons discovery.

Is this galaxy jumping through a giant ring of stars? Probably not. Although the precise dynamics behind the featured image is yet unclear, what is clear is that the pictured galaxy, NGC 7714, has been stretched and distorted by a recent collision with a neighboring galaxy. This smaller neighbor, NGC 7715, situated off to the left of the featured frame, is thought to have charged right through NGC 7714. Observations indicate that the golden ring pictured is composed of millions of older Sun-like stars that are likely co-moving with the interior bluer stars. In contrast, the bright center of NGC 7714 appears to be undergoing a burst of new star formation. The featured image was captured by the Hubble Space Telescope. NGC 7714 is located about 130 million light years away toward the constellation of the Two Fish (Pisces). The interactions between these galaxies likely started about 150 million years ago and should continue for several hundred million years more, after which a single central galaxy may result.

HiRISE views NASA's InSight and Curiosity on Mars
