The beautiful Trifid (not to be confused with Triffid) Nebula, also known as Messier 20, trisected by lines of cosmic dust. At top right is much-less-impressive Messier 21.

Silex Spring in Yellowstone National Park, Wyoming, is heated to steaming by the subterranean magma chamber called the Yellowstone Hotspot. The colors in the pool are caused by layers of bacteria that grow in the heated water. And of course that’s the Milky Way above it.

Arp 188, a galaxy also known, for some reason, as the Tadpole Galaxy. Its tail, 280 thousand light-years long, was possibly formed by a close encounter with another galaxy.

A geomorphological feature known as the Badlands Guardian, located near Medicine Hat in the southeast corner of Alberta, Canada. Although it seems to be made up of mountains, it’s actually a valley, caused by wind and water erosion of the soft, clay-rich soil.
As viewed from the air, the feature looks like a human head in a Native American headdress. Because of the man-made road and oil well, he also appears to be rocking earbuds.

The Lagoon Nebula, or M8, in the constellation of Sagittarius. The clouds are formed by stellar winds and energetic starlight. The very bright star at the left is Hershel 36.

The fissure of Laki, an Icelandic volcano. Unfortunately, the article it comes from (see link below) is about a volcano that is apparently about to erupt.

The August 10 supermoon: a full moon near perigee (point in its orbit closest to Earth). This composite photo records it as seen from the US east coast. If you missed it, the next one (not quite so super) will be September 8.

This is not Earth. The mountains in the background are one edge of Hebes Chasma on Mars, a depression north of Valles Marineris.
In the foreground is Hebes Mensa, a three-mile-high mesa that has collapsed at one end. Why? One hypothesis is that some of the lower layers of the rock making up the mesa contained a lot of salt, and that the salt has dissolved in melted ice flows that then drained into an underground aquifer.

This beautiful rose is M57, the Ring Nebula. The central ring can be seen with a small telescope, but this deep exposure, combining data from three telescopes, also shows the filaments of glowing gas extending out from it.
