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.

Daphnis and the Rings of Saturn
https://apod.nasa.gov/apod/ap191103.html
Explanation: What's happening to the rings of Saturn? A little moon making big waves. The moon is 8-kilometer Daphnis and it is making waves in the Keeler Gap of Saturn's rings using just its gravity -- as it bobs up and down, in and out. The featured image is a colored and more detailed version of a previously released images taken in 2017 by the robotic Cassini spacecraft during one of its Grand Finale orbits. Daphnis can be seen on the far right, sporting ridges likely accumulated from ring particles. Daphnis was discovered in Cassini images in 2005 and raised mounds of ring particles so high in 2009 -- during Saturn's equinox when the ring plane pointed directly at the Sun -- that they cast notable shadows.

Mercury Transit 2019: Where and How to See It on Nov. 11

On Nov. 11, people across most of the world can catch the planet Mercury passing across the sun. This rare event won't be seen from Earth again until 2032.

...

Mercury will begin its journey across the sun on Nov. 11 at 7:35 a.m. EST (1230 GMT), and the entire transit will take roughly 5 and a half hours, ending at 1:04 p.m. EST (1830 GMT), according to NASA.

The planet will look like a tiny, traveling blemish on the sun's face as it passes in front of the sun. The transiting world will be so small that skywatchers will need special gear — telescopes or binoculars equipped with protective solar filters — to see it.

There are four key parts to the entire event, beginning with the first contact, or the moment Mercury's silhouette first touches the edge of the sun […]
Second contact occurs at the instant that Mercury appears to have moved completely in front of the sun, Pesnell wrote. Third contact is when Mercury begins to cross over the edge of the sun's disk near the end of the transit, and fourth contact is the last moment Mercury's shadow touches the edge of the solar disk, marking the end of the transit.

You can use ocular projection with binoculars to watch it safely (but don't fry the prisms), or NASA's site for near real-time.
