A new class of planets has been  found orbiting stars besides our sun, in a possible giant leap  forward in the search for Earth-like planets that might harbor  life, scientists said on Tuesday.

The first precise measurement of a failed star known as a brown dwarf finds the object is much more massive than theorists expected. The result challenges what astronomers&nbsp;assumed about these strange things, which straddle the mass range between huge planets and normal stars.

AN Irish astronomer has discovered a giant planet orbiting a distant star using simple backyard telescopes.   Francis O'Donovan's team found the new world, - larger than Jupiter - orbiting a star 500 light years away in the Draco the Dragon constellation.  (c) 2006 Daily Mirror.

When a binary star system starts to transfer mass, one of the twins may well win out, leaving its companion to occupy a strange region half way between a star and a planet. A new star-type of this sort has been found, which resembles the infrared ash of a stillborn star.

Cambridge, MA - Scientists using NASA's Spitzer Space Telescope have discovered and directly imaged a small brown dwarf star, 50 times the mass of Jupiter, orbiting with a planet around a Sun-like star.

Most of the extrasolar planets discovered to date are gas giants like Jupiter, but their orbits are either much closer to their parent stars or are highly eccentric. Planet hunters are on the verge of confirming the discovery of Jupiter-size planets with Jupiter-like orbits. Solar systems that contain these "good" Jupiters may harbor habitable Earth-like planets as well.

The 130 extrasolar planets discovered so far are in solar systems very different from our own, in which life-bearing planets like Earth are unlikely to exist. But an obscure characteristic of these planets and their stars has led astronomers to predict that our galaxy is brimming with solar systems like ours. The key to their prediction is something called metallicity.

For the first time, scientists have found rings of dust around planet-bearing stars an important confirmation of theories about how planets form, NASA has announced.

Three new planets have been discovered in other solar systems that are the closest ever found to Earth in size, scientists announced today, marking an important step in the search for planets that could support life elsewhere in the universe.

Scientists said on Thursday they   have spotted an unusually large and light planet orbiting a   distant star -- a discovery that could force them to reexamine   theories about how planets are formed.
