Space Telescopes Spy Dusty Debris of Planets

A NASA-led team is studying the construction of a railway in space for a pair of telescopes that will provide views of planet, star, and galaxy formation in unprecedented detail. The proposed Space Infrared Interferometric Telescope (SPIRIT) mission will also examine the atmospheric chemistry of giant planets around other stars.

NASA's Spitzer Space Telescope has spotted a dusty disc of material around a very small "failed star" called a brown dwarf, raising the possibility that there may be miniature solar systems in which planets orbit objects not much larger than planets, scientists said Monday.

NEW YORK Ever since 1960, when a Cornell University astronomer named Frank Drake pointed a radio telescope at a pair of nearby stars on the chance that he might hear a &quot;howdy&quot; from extraterrestrial beings, astronomers have persevered in the notion that

A tiny telescope has spotted a giant planet circling a faraway star, using a technique that could open a new phase of planetary discovery, scientists said.

Using the largest telescopes available, astronomers have dissected the dusty, gassy layers of the red giant S Orionis-a star that pulsates in size from a diameter roughly equal to the orbit of Mars to that of Jupiter every 410 days.

UC Davis -- A new method for looking at the composition of comets using ground-based telescopes has been developed by chemists at UC Davis. Remnants from the formation of our solar system, the makeup of comets gives clues about how the Earth and other planets formed...

The Spitzer and Hubble Space Telescopes each have found dusty disks around sun-like stars. Finding such rings of dusty debris around stars the size of the sun is difficult, because they are fainter and harder

Astronomers plan to slam an armchair-sized "impactor" into comet Tempel 1 to see what's inside -- and possibly help future scientists determine how to keep such space rocks from colliding with Earth.
