Planets & Moon by Stewart Fitzgerald The most sensitive survey ever undertaken of the region in the Orion Nebula where new stars are forming has revealed 13 "free-floating planets" as well as more than one hundred very young brown dwarfs. The discovery was made by Dr Philip Lucas of the University of Hertfordshire and Dr Patrick Roche of the University of Oxford using a new camera on the United Kingdom Infrared Telescope (UKIRT) in Hawaii.

• Winter constellations setting over moonlit Death Valley; from Zabriskie PointTo estimate the number of the Milky Way’s stars, astronomers first assume there’s nothing special about our region of space. They determine the number of different types stars in this region – then extend this knowledge to the galaxy as a whole.
