An international team of astronomers reports the detection of two new exoplanets orbiting an evolved sun-like star known as HD 137496. The newly found extrasolar worlds, identified using NASA's Kepler spacecraft, were classified ...
Our familiar, warm, yellow sun is a relative rarity in the Milky Way. By far the most common stars are considerably smaller and cooler, sporting just half the mass of our sun at most. Billions of planets orbit these common ...
