NASA's Hubble Space Telescope caught a glimpse of 3I/ATLAS – in July and on Nov. 30, 2025. An ESA orbiter bound for Jupiter also observed the interstellar comet 3I/ATLAS. How big is 3I/ATLAS ...

NASA's alien-hunting Europa Clipper spacecraft took seven hours of ultraviolet observations of interstellar comet 3I/ATLAS while both objects zoom toward Jupiter. When you purchase through links on ...

The interstellar object 3I/ATLAS is expected to make its closest approach to Earth mere days from now, coming within just 167 million miles — a significant gulf, but a mere stone’s throw on the cosmic ...

Methanol has long been considered a basic building block of life as we know it: the molecule plays a crucial role in producing the proteins and amino acids that make up DNA and RNA, upon which all ...

We’ve likely had at least one close encounter of the 3I kind before. Harvard scientist Avi Loeb claims that not only does 3I/ATLAS potentially have alien origins, but that this wouldn’t be the first ...

The comet originated from outside our solar system and poses no danger to our planet. NASA officials have rejected theories that the object could be an alien spaceship. While not visible to the naked ...

Comet 3I/ATLAS—the third interstellar object ever known to pass through our solar system—is accelerating and now approaching its closest point to Earth. “Significant” non-gravitational accelerations ...

The comet poses no danger to Earth and will pass at a distance of about 170 million miles. Scientists are studying the object, which originated outside our solar system, using telescopes like Hubble ...
