An exceptionally rare visitor from beyond our solar system,interstellar comet 3I/ATLAS,is currently gracing the morning skies above the Czech Republic. First observed by local astronomer Martin Gembec of the Liberec Planetarium,this is only the third confirmed interstellar object detected passing through our star system-following ‘Oumuamua and 2I/Borisov-presenting a unique prospect for study. The comet, characterized by a distinctive greenish glow and lengthy ion tail, is visible with even modest telescopes as it makes its one-time journey through our neighborhood.
A rare astronomical event is visible in the skies over the Czech Republic this week: interstellar comet 3I/ATLAS, originating from a star system outside our own, is now observable from within the country’s borders. The comet was first spotted by Martin Gembec, head of the Liberec Planetarium, using a 10cm telescope in the Frýdlant region.
The comet appears as a greenish head with a long ion tail. While too faint to be seen with the naked eye, it presents an exceptional target for amateur astronomers. 3I/ATLAS is only the third confirmed interstellar object to pass through our solar system, following the detections of ʻOumuamua (1I/ʻOumuamua) and 2I/Borisov. Experts say this offers a unique opportunity to gain insight into the processes of planet formation in other star systems.
“It’s a mixture of ice and dust. What makes it special is that it came to us from another star. And now it’s finally visible in our morning sky. It’s not anything extraterrestrial, just an object from outside our solar system,” explains Martin Gembec from iQLANDIE.
His images reveal the comet’s distinct green hue and lengthy ion tail. He has also prepared a detailed analysis of its trajectory for the Czech Astronomical Society.

When and Where to Observe the Comet
Those hoping to catch a glimpse of this cosmic rarity should venture outside shortly before dawn. Finding a clear view of the eastern horizon is key, along with dark skies and clear weather. While the comet isn’t visible to the naked eye, a small telescope or telephoto lens will significantly improve viewing conditions in the coming days before sunrise.
Amateur astronomers have a unique opportunity to document an object that will pass through our solar system only once – and never return. This event underscores the ongoing efforts to map and understand objects originating from beyond our solar system.
Why is 3I/ATLAS so exceptional?
- It originates from interstellar space, having traveled for thousands or millions of years.
- Its green color is caused by the breakdown of carbon molecules (C₂).
- The ion tail always points away from the Sun due to the solar wind.
- It’s a one-time visitor, only passing through our solar system.
- It allows scientists to study material formed around another star.
