These planets, while roughly the size of our planet Earth, are circling very close to their star, giving them fiery temperatures that are most likely too hot to support life, researchers said.
For the first time, NASA's Kepler spacecraft has found two Earth-size planets outside our solar system – a landmark achievement. But the planets are in a solar system that baffles scientists and could overthrow current models of planet formation.
Scientists say they've found two planets that survived being swallowed by a red-giant star. Earth won't be so fortunate when our sun becomes a red giant in 5 billion years, but the find shows what can happen to solar systems after such dramatic events.
Asteroid Vesta is currently in the asteroid belt between Mars and Jupiter. Scientists recently discovered a huge mountain on the asteroid Vesta.
