We're in for a pre-Christmas treat this weekend, as the cosmos entertains us with two equally exciting gifts: the Geminid meteor shower and the interplanetary comet 46P/Wirtanen.
A winged spacecraft will soon take off with four NASA-supported technology experiments onboard. Virgin Galactic's SpaceShipTwo will separate from the WhiteKnightTwo twin-fuselage carrier aircraft and continue its rocket-powered ...
Japan's space agency says more than 200 photos taken by two small rovers on an asteroid show no signs of a smooth area for the planned touchdown of a spacecraft early next year.
In findings published today in The Astrophysical Journal, University of Texas at Austin astronomers report that they have stumbled on an extraordinary galaxy that may corroborate a recently contested theory about dark matter.
