The 3I/ATLAS interstellar comet’s size and physical properties are being investigated by astronomers around the world. Viewers can check the 3I/ATLAS positioning through live tracking available online, hosted by The Sky. In addition, space agencies are also streaming the 3I/ATLAS’ updates live with the comet’s positioning and more.

Named after the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey that first detected it, 3I/ATLAS includes the “I” designation to signify its interstellar origin, indicating that it came from beyond our solar system.

I/ATLAS is set to reach its closest point to the Sun on Wednesday (October 29), at around 11:47 Universal Time (UT). The comet will approach to about 1.36 astronomical units from the Sun. Follow our live blog for updates.

Astronomer Gianluca Masi and his Virtual Telescope Project will host a special livestream on Oct. 24 beginning at 1:30 p.m. EDT (1730 GMT) to watch as both comets make a close pass to Earth, making them well placed for observations.

Space junkies who live in the U.K. might want to tune into ITVX's "Space Live" channel which broadcasts views from the ISS 24/7 accompanied by serene music.

This 2020 astronaut photo shows the unusual cetacean-like shape of Belize's Lighthouse Reef. It's home to the famous Great Blue Hole, which doubles as the island's "blowhole" when viewed from space.

Its first modules were launched in 1998. The first crew to live on the International Space Station – an American and two Russians – entered it in 2000. Nov. 2, 2025, marks 25 years of continuous habitation by at least two people, and as many as 13 at one time. It is a singular example of international cooperation that has stood the test of time.
