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.
Highlights from the International Astronomical Union Symposium on “Exploring the Formation and Evolution of Planetary Systems”.
The disk around 49 Ceti is known to show characteristics of both protoplanetary and debris disks. New observations with Herschel reveal that it is likely a debris disk with gas generated by evaporating comets.
Detailed atmospheric models reveal that planets can be habitable much closer to their host star than previously thought, provided they have desert-like climates. This expanded definition of the habitable zone increases the number of planets that could support life by a factor of 2-3.
Spectroscopy with Herschel can probe the dust in the heart of protoplanetary disks through the 69 micron feature of forsterite. Examining these features in detail reveals that the dust grains are small, iron poor, and confined to narrow rings.
Astronomers search for radio signals from exoplanets discovered by Kepler. They find nothing. What does this imply about intelligent life elsewhere in the Galaxy?
