“2017 OF201 spends only 1% of its orbital time close enough to us to be detectable. The presence of this single object suggests that there could be another hundred or so other objects with similar ...

A newly discovered interstellar comet is hurtling around us, only the third interloper object to be observed in our solar system. It is not expected to pose an impact risk to Earth, but telescopes ...

A rare but faint interstellar visitor from beyond our solar system is racing toward the sun — and you can watch it live online today! Astronomers have identified this cosmic interloper as 3I/ATLAS, ...

The National Aeronautics and Space Administration has confirmed an interstellar object is passing through our solar system. The object is a comet hailing from the direction of the constellation ...

Nothing manmade has reached further from Earth than the Voyager series of spacecraft. Hurtling away from the sun at 38,000 miles an hour, the duo have now traveled over 12 billion miles, with Voyager ...

Voyager 1, launched in 1977, has traveled farther than any spacecraft in human history. After more than four decades of silent endurance through space, it now sails beyond the orbit of the outer ...

Astronomers have spotted what they think might be an "interstellar object" hurtling through the solar system — and it's headed toward us. The visiting space object, potentially the third of its kind ...

An accidental discovery might change how we think about one of the most mysterious structures in our solar system. The Oort Cloud, a large expanse of icy bodies revolving around the sun at a distance ...

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 ...

An interstellar object – a comet from a distant star system – is passing through the space between Jupiter and Mars, and according to a recent study, Comet 3I/Atlas may be 3 billion years older than ...

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 ...
