Explanation: Is there anything interesting to see in the direction opposite the Sun? One night last month, there were quite a few things. First, the red-glowing orb on the lower right of the featured image is the full moon, darkened and reddened because it has entered Earth's shadow. Beyond Earth's cone of darkness are backscattering dust particles orbiting the Sun that standout with a diffuse glow called the gegenschein, visible as a faint band rising from the central horizon and passing behind the Moon. A nearly horizontal stripe of green airglow is also discernable just above the horizon, partly blocked by blowing orange sand. Visible in the distant sky as the blue dot near the top of the image is the star Sirius, while the central band of our Milky Way Galaxy arches up on the image left and down again on the right. The fuzzy light patches just left of center are the Large and Small Magellanic Clouds. Red emission nebulas too numerous to mention are scattered about the sky, but are labelled in a companion annotated image. In the image forseground is the desolate Deadvlei region of the Namib-Naukluft National Park in Namibia, featuring the astrophotographer himself surveying a land and sky so amazing that he described it as one of the top experiences of his life.

This is a repeater, I’m sure of it.

Explanation: Long shadows are cast by a low Sun across this rugged looking terrain. Captured by New Horizons, the scene is found just south of the southern tip Sputnik Planum, the informally named smooth, bright heart region of Pluto. Centered is a feature provisionally known as Wright Mons, a broad, tall mountain, about 150 kilometers across and 4 kilometers high, with a 56 kilometer wide, deep summit depression. Of course, broad mountains with central craters are found elsewhere in the Solar System, like Mauna Loa on planet Earth and Olympus Mons on Mars. In fact, New Horizons scientists announced the striking similarity of Pluto's Wright Mons, and nearby Piccard Mons, to large shield volcanoes strongly suggests the two could be giant cryovolcanoes that once erupted molten ice from the interior of the cold, distant world.

That looks more like Uranus..................
;’)
Molten Ice? Sounds like a metal band name.
How does molten ice erupt, one wonders.
