Back in 2015, NASA’s Kepler mission spotted a planet that looked remarkably close to our own, a world now known as Kepler ...

NASA-funded studies suggest Earth’s climate has been influenced by both the Sun’s travels through dense regions of the Milky ...

An artist’s impression of the Earth–Theia impact, with the Sun in the background, illustrating the idea that Theia originated close to the Sun. A study led by Professor Nicolas DAUPHAS of the ...

Put Earth at the center of the Solar System and something has to give. Gravity does not negotiate, so if everything is going to orbit us, the masses have to be rearranged to allow it. Earth would need ...

Our solar system is a smashing success. A new study suggests that from its earliest period—even before the last of its nebular gas had been consumed—Earth's solar system and its planets looked more ...

New Haven, Conn. — Our solar system is a smashing success. A new study suggests that from its earliest period — even before the last of its nebular gas had been consumed — Earth’s solar system and its ...

Earth may owe some of its properties to a nearby star that blew up just as the solar system was forming. This pattern, which saw a supernova bubble envelop the sun and shower it with cosmic rays, may ...

Nearly 4.5 million years ago, two large, hot stars brushed tantalizingly close to Earth’s sun. They left behind a trace in the clouds of gas and dust that swirl just beyond our solar system—almost ...

New research challenges the long-held idea of “geomagnetic saturation,” suggesting Earth’s response to powerful solar storms may continue increasing instead of reaching a natural upper limit.
