Scientists: New Planets May Take Longer

It may take much longer than scientists have thought for violent turbulence to turn grains of space dust into new planets.

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.

By Matt Krupnick, Contra Costa Times, Walnut Creek, Calif. Feb. 17--BERKELEY -- UC Berkeley scientists will wait at least another day to study the lights in the northern sky.

The leading theory of how planets form is being revised because of new observations from the US Spitzer Space Telescope. The process is not as smooth and quiet as once thought, but rather the result of violent collisions between massive space rocks.

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.

More than one-third of the giant planet systems recently detected outside our solar system may harbor Earth-like planets covered in deep global oceans that offer abundant potential for life, according to a new study by scientists associated with NASA's Astrobiology Institute.

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.

A NASA telescope recently discovered evidence that the most violent part of the process in forming an Earth-sized planet - the collisions between colossal chunks of rock - may last hundreds of millions of years instead of 10 million years, scientists said

The universe looked a little more familiar and friendlier. The roll call of planets beyond the solar system swelled significantly with the announcement of a trio of newly-discovered worlds much smaller than any previously discovered around other stars.

The collisions that spawn planets are bigger and take place over longer periods of time than previously thought, say astronomers who studied nearly 300 stars with NASA&#39;s Spitzer Space Telescope.

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.
