A new hypothesis posits that the ice giant planets formed between the CO and N2 icelines in the Solar System’s protoplanetary disk.
Heat from the proto-Earth may have caused the difference in the Moon’s far- and near-side crust thicknesses.
A new model simulates the composition of growing planetesimals in an evolving protoplanetary disk. The model predicts that carbon-rich terrestrial planets can form more easily than previously thought.
Kepler finds the signature of a transiting white dwarf. Instead blocking the light of its companion star, the white dwarf magnifies it, creating a light curve that periodically brightens.
Vega’s system of debris disks can be explained by a series of planets that constantly transport material inwards towards the star.
The Kepler Space Telescope gets a promising second chance with a new mission called “K2″.
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.
A new debris disk is discovered by the Herschel Space Telescope around the red dwarf tertiary star in the famous Fomalhaut system.
The IceCube project at the South Pole makes the first detection of high-energy extraterrestrial neutrinos.
Herschel observations reveal that debris disks are aligned with their stars’ equators, unlike some close-in transiting exoplanets.
