The Latest Breaking News from the Solar System

Scientists debunk alien claims about interstellar comet 3I/Atlas, explaining its rare chemistry, deep-space age, and high speed as it passes through the Solar System.

Astronomers have ruled out alien origins for interstellar visitor 3I/ATLAS, confirming it's a natural comet—not an extraterrestrial spacecraft—while revealing clues about its ancient birthplace beyond the solar system.

NASA has confirmed that interstellar comet 3I/ATLAS safely passed Earth without any deviation from its predicted trajectory, dismissing online fears of a potential impact or orbital anomaly.

The rare interstellar comet 3I/ATLAS is under intense scrutiny as it passes through the solar system. Spacecraft like Hera, Europa Clipper, and JUICE are positioned to observe its unique 56,000 km ion tail.

NASA confirms the interstellar object 3I/ATLAS poses no threat to Earth, despite viral speculation. Scientists and the UN are monitoring the rare visitor to study its alien origins and composition.

When most of us think about what shaped our planet, we probably picture volcanoes, earthquakes, and huge continents slowly drifting apart (or back together again) over millions or billions of years. We also know meteorite impacts were important; our crater-packed Moon is clear evidence of that.

Is there a massive undiscovered planet on the outer reaches of the Solar System? The idea has been around since before the discovery of Pluto in the 1930s. Labelled as planet X, prominent astronomers had put it forward as an explanation for Uranus’s orbit, which drifts from the path of…

The new Sedonite, nicknamed Ammonite, was discovered by the 870MP camera on the Subaru Telescope

Astronomers have spotted a new interstellar object — the third of its kind ever seen — shooting towards us through the solar system. Here's everything you need to know about 3I/ATLAS.
