Astronomers Scope The Weather On Extrasolar Planet

Astronomer Joseph Harrington, of the University of Central Florida, has reported the first direct observation of distinct day and night temperatures on a planet orbiting another star. Unfortunately, the extrasolar (outside our solar system) planet doesn’t look to be very hospitable, as the temperatures range over 2,500 Fahrenheit between the night and day sides. Harrington […]

New Method To Find Extrasolar Planets

The latest issue of the journal Optical Letters carries an intriguing article about a new optical device that might allow astronomers to view extrasolar planets directly, without the distracting and concealing glare of the parent star. This would be accomplished by “nulling” out the light of the parent star by exploiting its wave nature, while […]

Earth’s Cousin Only 15 Light Years Away

Astronomers from the Ames Research Center and the University of California have discovered the most Earth-like planet yet, located only 15 light years from Earth. The new planet looks like a rocky world about 7.5 times as massive as the Earth. It travels in a nearly circular orbit only 2 million miles from its parent […]

First Photo Of Planet Outside Our Solar System

A team of astronomers has confirmed the discovery of a giant extra-solar planet, approximately five times the mass of Jupiter, that is gravitationally bound to a young brown dwarf star. The research, appearing in Astronomy and Astrophysics, puts an end to a year long discussion on the nature of this object, which started with the […]
