Latest Planetar Stories
An international team of astronomers led by David Pinfield of the University of Hertfordshire has found a brown dwarf that is more than 99% hydrogen and helium.
Astronomers have uncovered what appear to be 14 of the coldest stars known in our universe.
GREENBELT, Md., Aug. 28 /PRNewswire-USNewswire/ -- The dust-filled disks where new planets may be forming around other stars occasionally take on some difficult-to-understand shapes.
An international team, led by astronomers at the University of Hertfordshire in the UK, have discovered one of the coolest sub-stellar bodies ever found outside our own solar system, orbiting the red dwarf star Wolf 940, some 40 light years from Earth.
Processes that laid the foundation for life on Earth -- star and planet formation and the production of complex organic molecules in interstellar space -- are yielding their secrets to astronomers armed with powerful new research tools, and even better tools soon will be available.

Astronomers based at Jodrell Bank Observatory have found evidence that giant whirlpools form in the wake of stars as they move through clouds in interstellar space.
The 200 known planets that orbit other stars exhibit incredible variety. Among them are a handful of worlds that weigh between 5 and 15 times Earth. Astronomers believe these "super-Earths" are rocky iceballs rather than gas giants like Jupiter.
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.
Astronomers using Hubble have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet.
