Using radial velocity method a group of Japanese astronomers has found that two evolved stars, namely 24 Booties and Gamma Librae, are orbited by gas giant planets. They discovered that 24 Booties hosts one planet, while ...
Astronomers have detected "hot Jupiter" exoplanets transiting two distant stars. The newly found alien worlds, designated EPIC 229426032 b and EPIC 246067459 b, appear to be larger than it should be according to theoretical ...
Taking a picture of an exoplanet—a planet in a solar system beyond our sun—is no easy task. The light of a planet's parent star far outshines the light from the planet itself, making the planet difficult to see. While ...
