Latest gas-giant planets Stories
Results from the Gemini Observatory’s recently completed Planet-Finding Campaign reveal the outlying orbital space around many types of stars is largely devoid of gas-giant planets, which appear to remain close to their parent stars.
Astronomers have used ultrasharp images obtained with the Keck Telescope and Hubble Space Telescope to determine for the first time the masses of the coldest class of "failed stars," a.k.a. brown dwarfs.
A new explanation for forming "super-Earths" suggests that they are more likely to be found orbiting red dwarf stars -- the most abundant type of star -- than gas giant planets like Jupiter and Saturn.
New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun.
Using NASA's Spitzer Space Telescope, a team of astronomers led by the University of Rochester has detected gaps ringing the dusty disks around two very young stars, which suggests that gas-giant planets have formed there. A year ago, these same researchers found evidence of the first "baby planet" around a young star, challenging most astrophysicists's models of giant-planet formation.
