International study could aid search for life in the universe

A lunar eclipse helped a group of international scientists take a snapshot of earth's chemical fingerprint, which could help to identify planets most similar to earth where life may be thriving.

University of Central Florida Associate Professor Eduardo Martin was a member of the team that made the observation, which is published in the June 11 edition of Nature magazine.

First direct measurement of the mass of ultra-cool brown dwarf binary

An international team of astronomers using the world's biggest telescopes have directly measured the mass of an ultra-cool brown dwarf star and its companion dwarf star for the first time. Barely the size of the planet Jupiter, the dwarf star weighs in at just 8.5 percent of the mass of our Sun. This is the first ever mass measurement of a dwarf star belonging to a new stellar class of very low mass ultra-cool dwarf stars. The observation is a major step towards our understanding of the types of objects that occupy the gap between the lightest stars and the heaviest planets.
