Exactly when and how plate tectonics started, however, is a matter of debate. Now, in a study published March 19 in the journal Science, rock samples from Western Australia hint that the Earth’s crust may have been moving as early as 3.48 billion years ago, roughly one billion years after our planet formed.

The asteroid will make a close approach to Earth just three days following its discovery.

A major defense against everything space throws at us, Earth’s magnetic field may even protect the moon from damaging galactic cosmic rays

Webb telescope data shows a once-risky asteroid will safely pass Earth and the Moon in 2032, removing all impact concerns.

The Artemis II astronauts, after saying goodbye to family and friends, were strapped into their seats aboard the Orion spacecraft by early afternoon, hours before the launch window opened at 6:24 p.m. Eastern time.

Japan has an idea on how to power Earth with an endless supply of clean energy. It involves a mega-structure around the Moon.

The Artemis II crew provides an inspiring message from space, now closer to the Moon than Earth, capturing unique perspectives of our planet. NASA engineers also addressed a minor plumbing issue in the Orion spacecraft and continue testing new custom-fit orange space suits for crew safety.

The new Artemis II images — coupled with initial shots of the spacecraft hurtling through Earth's orbit, surrounded by glittering, galactic ice — have rendered much of the public awestruck, feeds flooding over with an overwhelming sense of emotion as the astronauts look back at our home.
