New images taken by the Hubble Space Telescope and a Jupiter-bound mission showcase interstellar comet 3I/ATLAS ahead of its ...

After cataloging thousands of worlds beyond our solar system, astronomers are now closing in on a far rarer prize: a moon ...

Stars form in massive clouds of gas called molecular clouds. As they form, they accrete gas from these clouds, and as the ...

It’s one of the most enduring ideas about the formation of our solar system: Earth collided with a Mars-sized object, Theia, and the debris from this cosmic crash eventually became the moon. But a new ...

Scientists traced the Moon's parent planet Theia to the inner Solar System, solving a 4.5-billion-year mystery.

The Kuiper belt, a disc of icy rocks on the outermost edges of the solar system, seems to have more structure than we thought. In 2011, researchers found a cluster of objects there on similar orbits ...

An interstellar trespasser known as 3I/ATLAS is almost certainly a comet. So, why do so many people think it's extraterrestrial technology?

How fast and in which direction is our solar system moving through the universe? This seemingly simple question is one of the key tests of our cosmological understanding. A research team led by ...

If you've ever wondered why we are here, then you can thank Jupiter for part of the answer. A new study from Rice University suggests that if it weren't for the gas giant, the Earth would have ...

Despite some similarities and speculation, the new comet likely originated from our solar system's Oort Cloud and is not directly connected to 3I/ATLAS. The comet will make its closest approach to ...

Having made its closest approach to the sun on Wednesday October 29, comet 3I/ATLAS will soon be visible from Earth again—before it leaves our solar system. While the comet—first spotted in July—has ...

The Uvalde, Texas project is slated to achieve commercial operation in 2026. Image: SOLV Energy. Independent power producer (IPP) Sol Systems has selected engineering, procurement, and construction ...
