The Kepler telesope discovered to planets orbiting around the same star!

NASA's Kepler spacecraft has discovered the first confirmed planetary system with more than one planet crossing in front of, or transiting, the same star.

The transit signatures of two distinct planets were seen in the data for the sun-like star designated Kepler-9. The planets were named Kepler-9b and 9c. The discovery incorporates seven months of observations of more than 156,000 stars as part of an ongoing search for Earth-sized planets outside our solar system

Image of the day: One Galaxy or two?

This image, taken from the Hubble Space Telescope in July 2001, shows a rather strange Galaxy. For the common eye, this may look as a Ring-Galaxy around a huge star, but for the amateur astronomer it seems like it would be a ring galaxy around another more compact galaxy. The strange thing about theese galaxies, is that the space between the galaxies is almost completely dark.

And if you look in the gap about 1' o clock, you can se another Ring-calaxy who is similiar to this one!

Strange isn't it?
