A New Look at How Planets Are Formed

New infrared observations of the disks of dust and rock around young stars reveal that many planets apparently form in an environment more violent and chaotic over a longer period of

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.

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.

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.

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.

A University of Colorado study has embarked on demonstrating that new planets can be found with the help of an orbiting starshade. The method has been compared to building a giant pinhole camera in space.

Planets form more violently than once thought, and many solar systems are strewn with dust from collisions like a blast that may have created Earth&#39;s moon, according to new findings.

The observations by NASA&#39;s Spitzer Space Telescope, linking with previous data from European satellites, demonstrated that the dust clouds in these proto-planetary disks did not steadily fade away over a few million years.

Astronomers in Europe and the United States have found two new planets about 20 times the size of Earth beyond the solar system. The discovery might be a giant leap forward in

Astronomers have discovered a new class of planets that take less than a day to whiz round their parent stars.
