In the past decade, astronomers have witnessed three interstellar objects (ISOs) passing through the solar system. These include the enigmatic 'Oumuamua in 2017, the interstellar comet 2I/Borisov in 2019, and 3I/ATLAS in ...
Sometimes serendipity happens in science. Whether it's an apple falling from a tree or a melting chocolate bar, some of the world's greatest discoveries come from happy accidents, even if their stories may be apocryphal. ...
Interstellar objects are visitors from solar systems beyond our own, and the third ever such object, known as 3I/ATLAS, has just been discovered. Using the Gemini North telescope, astronomers have captured 3I/ATLAS as it ...
A team of international astronomers, including a University of Michigan doctoral student, were the first to publish the discovery of just the third known interstellar object to visit our solar system on July 3.
When the news started to spread on July 1, 2025, about a new object that was spotted from outside our solar system, only the third of its kind ever known, astronomers at Michigan State University—along with a team of international ...
A mystery interstellar object discovered last week is likely to be the oldest comet ever seen—possibly predating our solar system by more than 3 billion years, researchers say.
Since 2017, three interstellar objects have been spotted passing through our solar system: 1I/ʻOumuamua, 2I/Borisov… and just this month, 3I/ATLAS. Discovered on July 1 by the Asteroid Terrestrial-Impact Last Alert Survey, ...
It feels like every week now we're writing a new article about how 3I/ATLAS is not an alien technology. But it's worth reiterating, and perhaps taking a look at the methodology we used to prove that statement. A new paper, ...
When 3I/ATLAS swept past the sun in late October 2025, it became only the third confirmed visitor from interstellar space ever detected. Unlike the mysterious 'Oumuamua, which revealed almost nothing about itself during its ...
A team of astronomers has taken the sharpest-ever picture of the unexpected interstellar comet 3I/ATLAS using the crisp vision of NASA's Hubble Space Telescope. Hubble is one of many missions across NASA's fleet of space ...
