The comet formed in a cold and distant part of the early Milky Way up to 12 billion years ago, putting it just under 2 ...

Interstellar objects move too fast and arrive too rarely for astronomy to rely on a single instrument or a single kind of light. When comet 3I/ATLAS was first reported on July 1, 2025, observatories ...

The interstellar comet 3I/ATLAS is leaving our solar system for good. Here's what to know about its journey and NASA's ...

A newly discovered interstellar comet known as 3I/ATLAS is racing through our Solar System on a hyperbolic trajectory at more than 68 km/s, offering scientists a rare chance to study material formed ...

It was "full-on erupting" during its flyby of the Sun. The post 3I/ATLAS Spraying Material as It Exits the Solar System appeared first on Futurism.

“While 3I/ATLAS is a visitor from interstellar space, travelling from outside the Solar System, its behaviour is completely ...

There have been plenty of attempts to resolve the "Hubble Tension" in cosmology. This feature describes how one of the most important variables in cosmology, the expansion of the universe, takes on ...

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

Astronomers surveying the outer solar system have revealed that a rare object far beyond Neptune is moving in sync with the eighth planet in an unexpected way. Called 2020 VN40 and first discovered in ...

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

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 ...
