More than 500 images, text messages and drawings were transmitted to a planet 20 light years away from Earth on Thursday by a massive radar telescope in the Ukraine that normally tracks asteroids. The recipient planet, known as Gliese 581C, was selected because scientists believe it is capable of supporting life.  However, any reply to the messages would not return to Earth for 40 years.  The effort is part of a competition known as "A Message From Earth" that is being sponsored...

By studying in great detail the 'ringing' of a planet-harboring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster. This discovery has implications for theories of star and planet formation, and for the dynamics of our Milky Way.The yellow-orange star Iota Horologii, located 56 light-years away towards the southern Horologium ("The Clock") constellation, belongs to the so-called "Hyades stream", a large number...

HARPS Instrument Finds Unusual Planetary System Using the ultra-precise HARPS spectrograph on ESO's 3.6-m telescope at La Silla (Chile), a team of European astronomers have discovered that a nearby star is host to three Neptune-mass planets. The innermost planet is most probably rocky, while the outermost is the first known Neptune-mass planet to reside in the habitable zone. This unique system is likely further enriched by an asteroid belt. "For the first time, we have discovered a...

SANTIAGO, Chile -- Scientists using a Chilean telescope have discovered a unique planetary system made up of three planets similar to Neptune orbiting a star a little more massive than our sun, the European Southern Observatory said on Wednesday. "The planet closest to the star is probably rocky and the farthest is the first exoplanet of that mass that is in the habitable zone of its star, meaning, where water could be found in liquid form," the observatory said in a news release. An...

A team of French and Swiss astronomers [1] have discovered one of the lightest exoplanets ever found using the HARPS instrument [2] on ESO's 3.6-m telescope at La Silla (Chile). The new planet orbits a star belonging to the class of red dwarfs. As these stars are very common, this discovery proves crucial in the census of other planetary systems. "Our finding possibly means that planets are rather frequent around the smallest stars," says Xavier Delfosse, from the Laboratoire d'Astrophysique...
