A team of astronomers has discovered a large, ice-rock planet that dominates a distant solar system, much like Jupiter reigns in our bit of Milky Way real estate.
Taking into account other discoveries of extrasolar planets, the finding of an Earth-class planet leads scientists to theorize that the type of planetary system that develops around a star depends on the size of the star.
"Our discovery suggests that different types of solar systems form around different types of stars," said astronomer Scott Gaudi, with the Harvard-Smithsonian Center for Astrophysics.
Stars like our sun form systems with Jupiter-class planets, while smaller red dwarf stars, which are common in the Milky Way galaxy, can support a system dominated only by a large Earth-class world.

Scientists Report an Odd Twist Near Milky Way Center

Using observations from NASA's Spitzer Space Telescope, astronomers report an unprecedented elongated double helix nebula near the center of our Milky Way galaxy. The part of the nebula the astronomers observed stretches 80 light years in length. The research is published March 16 issue of the journal Nature.
"We see two intertwining strands wrapped around each other as in a DNA molecule," said Mark Morris, UCLA professor of physics and astronomy, and lead author. "Nobody has ever seen anything like that before in the cosmic realm. Most nebulae are either spiral galaxies full of stars or formless amorphous conglomerations of dust and gas — space weather. "

Konacno!!!!
Lepo ja kazem da ne postoji "velicina" i da se nalazimo u telu nekog bica!
:D :D :D
U svakom slucaju interesantno!
Sta je gospodja Klotz htela da kaze, nije mi jasno uopste.. Jel imas mozda jos neki link za istu 'vest'?
Lepe vesti, mada mislim da ako smo zaista u telu nekog "bica" nadrljali smo! Hehehe salu na stranu, pa doticna gospodja je verovatno rekla sve sto je imala da kaze, sad ostaje na nama da to malo podrobnije izucavamo... :wink:
