Hubble Finds Hunks of Planet Orbiting Dead Stars

Pollution is a growing concern here on Earth, but in a nearby star cluster pollution is actually proving pretty useful. Astronomers analyzing Hubble data have found that a pair of white dwarfs — the tiny, final form most of the universe’s stars will assume — show signs of “pollution” from asteroid and planet-like debris falling upon them. The discovery not only underscores just how widespread rocky worlds are, but also opens the way to a new way of studying planet formation.

Heady mathematics: Describing popping bubbles in a foam

Two applied mathematicians have found a way to mathematically describe the evolution and disappearance of a foam. Using these equations, they were able to generate a movie that shows the complex draining, popping and rearrangement of these bubbles as the foam vanishes.
