Totally lied about coming back. Well, I've actually been kinda busy. But I took a video of the Sun, for anyone left following, enjoy it!

|On the left, NASA's Solar Dynamics Observatory shows the magnetic rope as the thick looped structure extending above the edge of the sun. On the right, SDO observes as the surrounding cool magnetic field lines are pushed away by the intruding magnetic rope seen on the left. Both images are taken almost simultaneously (within three seconds of each other). [Credit: NASA and GMU]|

|This hemispheric view of Venus was created using more than a decade of radar investigations culminating in the 1990-1994 Magellan mission, and is centered on the planet's North Pole. This composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation. Image Credit: NASA/JPL/USGS|

There's clearly a deep crater in the northern part of the image. And the outline is definitely lumpier than the outlines of similarly sized bodies in the outer solar system (like Mimas and Enceladus), but we knew that already; the rock that Vesta is made of is able to hold up steeper mountains than the relatively low-strength ices that outer planet moons are made of. Apart from that, it's still hard to tell what's albedo differences and what's topography. But that won't be true for long.

|Degas crater imaged as a high-resolution targeted observation (90 m/pixel). Impact melt coats its floor, and as the melt cooled and shrank, it formed the cracks observed across the crater. For context, Mariner 10’s view of Degas is shown at left. Degas is 52 km in diameter. Image Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington|

"We are assembling a global overview of the nature and workings of Mercury for the first time and many of our earlier ideas are being cast aside as new observations lead to new insights. Our primary mission has another three Mercury years to run, and we can expect more surprises as our solar system's innermost planet reveals its long-held secrets."

"The sun's magnetic field extends all the way to the edge of the solar system. Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are, the folds of the skirt bunch up."Another amazing find from the astronomical community. This discovery will also help to build a better understanding about how galactic cosmic rays enter our solar system and help define how the star interacts with the rest of the galaxy.
