Heart of Fire
Mother Earth wishes you all a Happy Valentine’s Day!
This iconic 1996 photo of the West Kamokuna skylight in Hawai'i by Dr. Laszlo Kestay of the USGS shows crystalized lava that has flowed and solidified into contorted channels while molten rock continues to flow underneath it. For scale, the lava wall is about 4 meters high.

Phobos
Phobos is the larger of Mars' two moons and is 27 by 22 by 18 kilometers in size. It orbits Mars three times a day and is so close to the planet's surface that in some locations on Mars, it cannot always be seen. Phobos is nearing Mars at a rate of 1.8 meters every hundred years; at that rate, it will either crash into Mars in 50 million years or break up into a ring.

A Different View of Saturn
There is a lot going on in this image from the Cassini spacecraft. What you see are not the actual rings of Saturn (D and C) but the projection of their shadow on the atmosphere and, yes, clouds underneath.
