One distant star has three planets, another at least one. Not news perhaps, we've detected extrasolar planets before. But now we humans have out first-ever direct visual images of worlds far beyond out own. Two teams - one using the Hubble Space Telescope, the other a pair of telescopes in Hawaii - have given us these historic images.
The Hubble image shows the star Fomalhaut and a planet three times larger than Jupiter. The ground-based image showsthree much larger planets circling a star called HR 8799. (Don't despair if what you seek are "Class M" planets like ours: it's only logical that the first exoplanets we see will be the biggest ones. There may be a host of smaller ones around these same stars, waiting for our tools to grow sharper.)
