Can Scattering Explain Eccentric Planets?
New dynamical simulations show that close-in planets on eccentric orbits can arise from planet-planet scattering — but only if the scattering occurs on larger orbits and is followed by inward migration.
Fomalhaut’s Little Sibling Has a Debris Disk Too
A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.
IceCube Detects Extraterrestrial Neutrinos
The IceCube project at the South Pole makes the first detection of high-energy extraterrestrial neutrinos.
Debris Disks and Stars Spin Together
Herschel observations reveal that debris disks are aligned with their stars’ equators, unlike some close-in transiting exoplanets.
How Did Tatooine Form?
Dust traps may be the key to forming Kepler-16b and other circumbinary planets.
