16 Cygni (ScienceNOW)
16 Cygni is a triple-star system 69 light-years from us. It's turning out to be an interesting one. It consists of two yellow suns and a dim red one. Both yellow suns are now known to have planets. Also, the system is 2 billion years older than our own.

And here's a very similar triple star: two yellow stars and a little red one. Only the interesting thing about this one is that the little red star has a planet in its habitable zone – the right distance to have liquid water on its surface. Not that we know anything yet about its atmosphere or surface gravity.
Planetary electrons (New Scientist)
The image of electrons orbiting an atomic nucleus like little planets is easily recognizable, but it's almost a cartoon. In regular atoms, the electrons form a haze of cloud around the nucleus. But Rydberg atoms are huge (for atoms): half a millimeter wide. They are so big, their electrons localize and really do orbit around the nucleus as planets do about a sun.
