Earth has a large amount of water and a relatively large moon, which stabilizes Earth’s axis. Both are essential for life to develop on our planet. Scientists have now been able to show that water came to Earth with the formation of the moon.

Planetologists at the University of Münster (Germany) have now been able to show, for the first time, that water came to Earth with the formation of the Moon some 4.4 billion years ago. The Moon was formed when Earth was hit by a body about the size of Mars, also called Theia. Until now, scientists had assumed that Theia originated in the inner solar system near the Earth...

A gassy insulating layer beneath the icy surfaces of distant celestial objects could mean there are more oceans in the universe than previously thought. Computer simulations provide compelling evidence that an insulating layer of gas hydrates could keep a subsurface ocean from freezing beneath Pluto’s icy exterior, according to a study published in the journal Nature Geoscience.

In July 2015, NASA’s New Horizons spacecraft flew through Pluto’s system, providing the first-ever close-up im...

Astronomers using the combined power of two Hawaii telescopes have taken groundbreaking, sharp new images of a distant planetary system that likely resembles a baby version of our solar system.

Using Subaru Telescope and W. M. Keck Observatory, the team obtained and analyzed data for an infant Sun-like star named LkCa 15. Previous studies using an advanced interferometry method had inferred that three infant planets were orbiting this star...

The irregular galaxy NGC 4485 shows all the signs of having been involved in a hit-and-run accident with a bypassing galaxy. Rather than destroying the galaxy, the chance encounter is spawning a new generation of stars, and presumably planets.

The right side of the galaxy is ablaze with star formation, shown in the plethora of young blue stars and star-incubating pinkish nebulas. The left side, however, looks intact...
