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

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.

It may take much longer than scientists have thought for violent turbulence to turn grains of space dust into new planets. A NASA (news - web sites) telescope

Astronomers have found the latest planet in another solar system â-r &quot;exoplanet&quot; â -ng telescopes no bigger than those you might find at a garage sale.

Suggesting a necessary change to astronomy textbooks, astronomers announced Monday that planets form through a lengthier and more violent series of collisions

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.

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.

NASA's Spitzer Space Telescope has captured for the first time enough light from planets outside our solar system, known as exoplanets, to identify signatures of molecules in their atmospheres.

Interesting data has been sent by the Cassini spacecraft from Saturn back to astronomers on Earth. The results provide insight into the planet&#39;s rings and how the planet has evolved lately.

Astronomers discover a newborn planet in a solar system that is still in the process of forming.

US astronomers show that wherever there is room for a planet to form around a young star, it does.

New observations of dust around young stars suggest collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn&#39;t likely stop the formation

By ALICIA CHANG  SAN FRANCISCO - Detailed observations from the first comet samples returned to Earth are debunking some of science's long-held beliefs on how the icy, celestial bodies form.

In a solar system thousands of light years away, a star about half the size of our sun is being orbited by two planets that seem like smaller versions of Jupiter and Saturn, astronomers report

New observations of dust around young stars suggests collisions of large asteroid-like objects and fledgling planets are frequent. But that doesn't likely stop the formation of rocky planets like Earth, a process that may well be common, the results suggest.

Researchers have discovered two planets in a solar system 5,000 light-years away that appears to be structured in some important ways like our own.

A newfound planet detected by a small, 4-inch-diameter telescope demonstrates that we are at the cusp of a new age of planet discovery. Soon, new worlds may be located at an accelerating pace, bringing the detection of the first Earth-sized world one step closer.
