We will share live, online images of the interstellar comet 3I/ATLAS on the day of its minimum distance from the Earth. Support the Virtual Telescope Project and receive an exclusive image of interstellar comet...
We imaged the interstellar comet 3I/ATLAS (C/2025 N1 ATLAS) under good sky conditions, recording its fascinating ion tail. The image above comes from the sigma-clipping combination of 11, 120-second exposures, remotely taken with the...
Exploiting the unusual good weather of this season, we imaged the interstellar comet 3I/ATLAS (C/2025 N1 ATLAS) again, recording a much more developed ion tail. The image above comes from the sigma-clipping combination of...
While observing conditions improve, we spotted again the interstellar comet 3I/ATLAS (C/2025 N1 ATLAS), detecting the complex signature of its ion tail. The image above comes from the sigma-clipping combination of 14, 120-second exposures,...
We observed again the interstellar comet 3I/ATLAS, after its recent conjunction with the Sun. Its coma is clearly visible, despite the extreme observing conditions. The image above comes from the average of six, 60-second...
We succeeded imaging the interstellar comet 3I/ATLAS after its recent conjunction with the Sun, starting our post-perihelion observing season of this extraordinary object, looking forward to show it live to the community. The image...
Un breve profilo della cometa interstellare 3I/ATLAS (C/2025 N1 ATLAS), ora che si appresta a farsi osservare nuovamente dalla Terra. Il 1 luglio, nel corso del proprio programma di ricerca di asteroidi capaci di...
Now that this important object is going to show again in our sky, after its recent conjunction with the Sun, we will offer to the community the unique opportunity to see the interstellar comet...
On 31 July 2025, we imaged 3I/ATLAS = C/2025 N1 (ATLAS), as part of our coverage of this exceptional object. We succeeded detecting its faint coma. The image above comes from the combination of...
On July 1st, astronomers discovered a celestial body passing through the region of the Sun, but originating from beyond the Solar System: it is 3I/ATLAS = C/2025 N1 (ATLAS). It’s the 3rd ever of this...
A new interstellar object, temporarily named A11pl3Z then officially 3I/ATLAS = C/2025 N1 (ATLAS), has been just discovered. It’s the third one ever found. We will show it live, online: join us from the...
After our first images of this unique object, we captured again the interstellar comet 2I/Borisov under excellent sky conditions, recording a coma and a tail. Here it is our new image. Few days after...
It is now official: we have the first interstellar comet ever discovered. It is named 2I/Borisov, after we called it C/2019 Q4 for a while. “I” stays for “Interstellar”. Our data was published in...
After our first observation of the interstellar comet C/2019 Q4 Borisov, we could image it again, despite a very bright Moon, the imminent sunrise and the low altitude of the target above the horizon....
