| The possible exoplanet is orbiting a star known as GQ Lup, thought to be similar to our own Sun, when it was younger. |
|
| Could it be an exoplanet in orbit around that young brown dwarf object at a projected distance of about 8,250 million km? |
|
| The superb light curves of the space telescope CoRoT gave us the best radius measurement, and HARPS the best mass measurement for an exoplanet. |
|
| The exoplanet HD 209458b, like the other gas giants found through Doppler surveys of Sun-like stars, is too faint to be seen in any image. |
|
| Imaging an exoplanet poses an enormous technical challenge, since its luminosity is many millions of times less than that of its parent star. |
|
| The first potentially habitable exoplanet was discovered orbiting the star Gliese 581, which is 20.5 lightyears away. |
|
| Small red stars vastly outnumber their larger cousins, and the new exoplanet is orbiting one of those. |
|
| The same group of astronomers has also inferred a type of exoplanet that fits in between the rocky planets and the gas giants. |
|
| The first exoplanet orbiting a normal star was discovered a mere 12 years ago. |
|
| We are now entering a new era in exoplanet research: the study of complex planetary systems and not just of individual planets. |
|
| Imagine, though, a Saturn-mass exoplanet with a Titan-sized moon orbiting its star within the habitable zone. |
|
| The initial set of measurements, however, could not provide the mass of the exoplanet. |
|
| The news of an exoplanet discovery is hardly earthshaking anymore, which is disappointing in a way. |
|
| It is the second smallest exoplanet discovered by the CoRoT team so far after CoRoT-7b, the first transiting Super-Earth. |
|
| They theorize that the object that cleared the dust is an exoplanet at least as large as Jupiter. |
|
| The exoplanet Corot-7b is so close to its Sun-like host star that it must experience extreme conditions. |
|
| Its period of rotation around its star is 9.2 days, which is the second longer period known to date for an exoplanet discovered by transit. |
|
| A first step in this quest was taken in 1995 when scientists detected the first planet outside our solar system: an exoplanet similar to Jupiter. |
|
| The exoplanet is orbiting around the red dwarf star TW Hydrae within the constellation Hydra, located 176 light-years from Earth. |
|
| The system then blocks the star with a device called a coronagraph, revealing the exoplanet. |
|
|
|
| Just a fortnight ago, astronomers using the Hubble space telescope identified for the first time water vapour in the atmosphere of an exoplanet, albeit a gaseous one some 150 light years away. |
|
| A few weeks ago, two international teams discover, by the method of radial velocities, a news exoplanet around star HD 209458, in the constellation of Pegasus. |
|
| About a dozen of these bodies have been detected, though in the case of CoRoT-7b, this is the first time that the density has been measured for such a small exoplanet. |
|
| Such a result requires extremely precise measurements of the velocity of the star, which is pulled a tiny amount by the gravitational tug of the orbiting exoplanet. |
|
| The CoRoT satellite, developed by CNES, has allowed the discovery of the smallest exoplanet ever characterized, of a size comparable to that of the Earth. |
|
| An extrasolar planet or exoplanet is any planet outside our solar system. |
|
| At 3,860 kilometers across, the exoplanet is about 30 percent of the diameter of Earth or 80 percent the width of Mercury. |
|
| In October 2012 Madhusudhan published a paper arguing that 55 Cancri e, a rocky exoplanet twice Earth's size, is likely covered in graphite and diamond. |
