This one shows an interacting binary with a cool lobe-filling star that is dumping matter onto a white dwarf companion. I recently moved to Boulder, Colorado and the dominant geological feature here is known as the Flatirons. When it snows, the relief on the flatirons really stands out. This planet orbits the hot,active star and the other hot companion star is off in the distance. Binary Supernova - A star in a binary system undergoes a supernova explosion.
Some older stuff is here .
