Observational biases may significantly underestimate the lifetime of protoplanetary disks.
Herschel provides an updated look at the debris disk in the popular planetary system, Tau Ceti.
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.
