Earth and other terrestrial planets probably use their gravitational forces to tear apart asteroids ― but this creates more streams of smaller asteroids.

Our solar system has been orbiting the Milky Way's black hole heart for 4.6 billion years. But it is hard to pin down exactly how many trips around the galaxy our sun has made during that time.

Intense pressure and sweltering temperature would accompany a trip down through Earth's layers and out through the other side. However, this trip would be possible only in science fiction.

Asteroids with different spins and bonding strengths may be responsible for the vast variety of impact craters on Earth, including Arizona's Barringer Crater, new simulations show.

The first life-forms capable of evolution could have appeared just moments after the Big Bang, a physicist explains.

We worked out how many trips each of the solar system's eight planets has taken around the sun over the past 4.6 billion years.

Humans will likely die long before our planet does.

A recent solar explosion that almost reached "X-class" status has hurled a massive coronal mass ejection toward Earth, which will likely hit our planet and trigger a geomagnetic storm on Dec. 1.

Earth will become too hot to handle in a billion years. There's a (very) remote chance a passing star could save us by knocking our planet back into the habitable zone.

The NISAR satellite, a collaboration between NASA and India's space agency ISRO, will help scientists monitor how climate change is affecting Earth's varied landscapes.
