Interstellar objects like 3I/ATLAS are most likely to enter our solar system from two specific directions, a new study suggests. What does it mean for Earth? When you purchase through links on our ...

Illustration comparing the planets of the Solar System and the Sun on the same scale. The planets are shown to scale relative to each other but their distances are not. From left to right the bodies ...

Astrophysicists are mapping a vast, hidden structure in space that appears to guide matter and radiation along a kind of interstellar highway stretching from our solar neighborhood to distant stars.

The workings of our solar system are roughly the same now as they have been for millions of years. Moons circle their planets, the planets circle the sun, the sun’s magnetic fields and sunspots wax ...

There’s a visitor in town, and its name is 3I/ATLAS. The presumed interstellar comet presents a rare opportunity for astronomers to study an object born a long time ago in a star system far, far away.

PUNCH’s observations of comet 3I/ATLAS from Sept. 28 to Oct. 10, 2025, when the comet was between 231 million to 235 million miles from Earth. Each frame is a daily stacked image, made up of multiple ...

Peering through a cosmic keyhole at distant baby star, astronomers may have opened a new window on the deep past of our own solar system. Weighing in at 0.6 solar mass, HOPS-315 should someday grow to ...

"Our analysis shows that the solar system is moving more than three times faster than current models predict," says lead author Böhme. "This result clearly contradicts expectations based on standard ...

A small, icy traveler from deep space has just threaded its way through the inner Solar System, offering a fleeting but profound reminder that our planetary neighborhood is not isolated. As ...

In a new study, researchers from Penn State and NASA’s Jet Propulsion Laboratory analyzed human deep space communications and found that human transmissions are frequently directed toward our own ...

LONDON — 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 ...
