First Habitable Planet Confirmed by French Scientists
French scientists believe that a planet orbiting the red dwarf star Gliese 581 could sustain life similar to Earth.
Twenty light years away is a small red star. Orbiting this sun are six planets that range in size from slightly smaller than Earth to about the size of Neptune. Several of these planets fall within the star's "Goldilocks" zone, neither too hot from proximity to the star nor too cold from being too far. If a planet is too hot, all water would be steam but if its too cold then it would be ice, neither of which can support life. Luckily, a group of astronomers from the National Centre for Scientific Research in France believe that the fourth planet - unimaginatively labeled Gliese 581d - is just right.

Random Image #3
Hello there! After some time away from the blog I'm back. Today I bring this image from NASA's site. Enjoy!
Explanation:
Nebulae are enormous clouds of dust and gas occupying the space between the stars.

10 Most Fascinating Galaxies of our Universe
1 - The Sombrero Galaxy
The Sombrero Galaxy (also known as M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo. It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk. The dark dust lane and the bulge give this galaxy the appearance of a sombrero. The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes. The large bulge, the central supermassive black hole, and the dust lane all attract the attention of professional astronomers.
2 - Black Eye Galaxy
A spiral galaxy in the Coma Berenices constellation, Messier 64, the famous "Black Eye" galaxy or the "Sleeping Beauty galaxy," has a spectacular dark band of absorbing dust in front of the galaxy's bright nucleus. It is well known among amateur astronomers because of its appearance in small telescopes.
