A tiny telescope has spotted a giant planet circling a faraway star, using a technique that could open a new phase of planetary discovery, scientists say.

Observing the image of a faint object that lies close to a star is a demanding task as the object is generally hidden in the glare of the star. Characterising this object, by taking spectra, is an even harder challenge.

The first precise measurement of a failed star known as a brown dwarf finds the object is much more massive than theorists expected. The result challenges what astronomers&nbsp;assumed about these strange things, which straddle the mass range between huge planets and normal stars.

Is this newly discovered feeble point of light the long-sought bona-fide image of an exoplanet? A research paper by an international team of astronomers provides sound arguments in favor, but the definitive answer is now awaiting further observations.

NASA's Spitzer Space Telescope has captured for the first time enough light from planets outside our solar system, known as exoplanets, to identify signatures of molecules in their atmospheres.

A newfound planet detected by a small, 4-inch-diameter telescope demonstrates that we are at the cusp of a new age of planet discovery. Soon, new worlds may be located at an accelerating pace, bringing the detection of the first Earth-sized world one step closer.

NASA's Opportunity Mars rover has come across  an interesting object&nbsp;-- perhaps a meteorite sitting out in the open at Meridiani  Planum. Initial data taken by the robot's Mini-Thermal Emission Spectrometer  (Mini-TES) is suggestive that the odd-looking rock is made of  metal.
