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.
Dust traps may be the key to forming Kepler-16b and other circumbinary planets.
NASA is looking for a new mission for the damaged Kepler space telescope. Here are some ideas.
The mass of the cores of giant planets affects their luminosity after formation, complicating how we determine the mass of directly imaged planets.
