Latest Optical Gravitational Lensing Experiment Stories
WASHINGTON (Reuters) - A cold, heavy "super-Earth" has been found orbiting a distant star, using a method that holds promise for detecting faraway planets that closely resemble our own, astronomers said on Monday.
Astronomers have discovered a new "super-Earth" orbiting a red dwarf star located about 9,000 light-years away. This newfound world weighs about 13 times the mass of the Earth and is probably a mixture of rock and ice, with a diameter several times that of Earth.
A new planet-hunting technique has detected the most Earth-like planet yet around a star other than our sun, raising hopes of finding a space rock that might support life, astronomers reported on Wednesday.
Using an armada of telescopes, an international team of astronomers has found the smallest planet ever detected around a normal star outside our solar system. The extrasolar planet is five times as massive as Earth and orbits a red dwarf.
Fifty years after his death, Albert Einsteinâ€™s work still provides new tools for understanding our universe. An international team of astronomers has now used a phenomenon first predicted by Einstein in 1936, called gravitational lensing, to determine the shape of stars.
For the first time, amateur and professional astronomers have teamed up to discover a new planet circling a distant star. The planet was detected by looking for the effect of its gravitational field on light from a more distant star, a technique known as microlensing.
An international team of astronomers have accurately determined the radius and mass of the smallest core-burning star known until now.
