For billions of years, the Sun’s gravitational has kept Earth’s orbit on a steady and reliable path. But this rogue star has ...

An international team of astronomers reports the discovery of two new exoplanets, a few times more massive than Earth, orbiting a sun-like star known as HD 35843. The finding was reported in a ...

A new image of an asteroid, referred to as a “quasi-moon,” has been released ...

Add Yahoo as a preferred source to see more of our stories on Google. An illustration depicts what the surface of one of the exoplanets orbiting Barnard's Star may look like. The other three planets ...

Earth is millions of miles farther from the Sun in July than it is in January. So why doesn’t summer suddenly feel cooler?

Scientists continue to mine data gathered by NASA's Kepler Space Telescope, retired in 2018, and continue to turn up surprises. A new paper reveals the latest: a possible rocky planet slightly larger ...

Finding Earth-like planets orbiting sun-like stars and identifying signs of life such as oxygen or water is a major goal in astronomy and a key interest for the public. Addressing this challenge ...

Thanks to the Kepler Space Telescope, NASA has announced the discovery of the first near-Earth size planet in the so-called habitable zone around another star 1,400 light-years from Earth, in the ...

Instead, it was orbiting parallel to Earth, following the same orbit around the Sun. That makes it a "quasi-moon," a sort of space companion that plots out its course in sync with Earth but is not ...

Spotting Earth-like planets is nearly impossible with conventional telescopes, but researchers propose a bold fix: a rectangular design that can separate a planet’s faint glow from its blinding star.
