As we push spacecraft to the edges of our solar system and beyond, it gets harder and harder to navigate them from Earth. But what if spacecraft could steer themselves, using observations of pulsars? Read on to find out how!
TITLE: Supernovae in the Central Parsec: A Mechanism for Producing Spatially Anisotropic Hypervelocity Stars AUTHORS: Kastytis Zubovas, Graham A. Wynn, Alessia Gualandris AUTHORS’ INSTITUTION: Theoretical Astrophysics Group, University of Leicester Hypervelocity Stars In 2005, Brown et al. discovered a star with a radial velocity of ~700 km/s, which is more than 3 times the Solar [...]
Our simple formula for predicting the probability that an exoplanet will transit might miss something important.
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.
Star formation is enhanced when two galaxies interact or merge. But what is the orbital extent of enhanced star formation in interacting galaxies? At which projected separation of the two galaxies does it disappear?
