About 4.6 billion years ago, the Solar System formed from a cloud of dust and gas collapsing in on itself due to gravity. The Sun, planets, and eventually Earth formed out of the cloud. But when did ...

It's probably a comet, but it might be some sort of ancient alien spacecraft or probe. What's for sure is that the mystery surrounding an object known as 3I/ATLAS is becoming both more and ...

Tesla announced that it is reviving solar leasing after years of allowing its solar business to slowly decline over the last few years. The company had even stopped reporting solar installations.

The search for an unknown planet in our solar system has inspired astronomers for more than a century. Now, a recent study suggests a potential new candidate, which the paper’s authors have dubbed ...

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 ...

A massive comet traveling through the solar system is much larger than previously thought and could be a remnant of alien technology, a scientist claims in a new report. 3I/ATLAS was first identified ...

A comet traveling outside the solar system and heading toward the Earth is much larger than scientists first believed, a scientist has detailed in a new report. Avi Loeb claims the comet could even be ...

This illustration shows the creation of an asteroid family. Ejected fragments from catastrophic collisions of asteroids between Mars and Jupiter tend to follow similar orbits around the sun, allowing ...

3I/ATLAS likely weighs more than 33 billion tons. The interstellar object hurtling toward the inner solar system, where Earth is located, is much larger than previously thought, astronomers say. A ...
