Researchers rarely get a glimpse of an interstellar object up close like 3I-ATLAS, so they have jumped on the opportunity to learn about its composition, which can reveal how planet systems are made.

An interstellar comet that originated outside our solar system just flew by the sun. Next, the object will fly by Earth in December.

Astronomers believe 3I/ATLAS, a fast-moving interstellar object, may be a 10-billion-year-old relic from the galaxy’s ...

Anyone who studies planetary formation would relish the opportunity to get a close-up look at an interstellar object. Sending a mission to one would undoubtedly yield a scientific payoff. There’s a ...

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 ...

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 ...
