'polluting' the atmospheres of two white dwarfs.

kilometers-deep lakes that spilled catastrophically from one to another
early in martian history.
Ever tried to comprehend the magnitude of the cosmos and some
of its most energetic processes? If so, the X-ray halo around the
merging galaxies known as NGC 6240 may just blow your mind.
