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....
For the very first time, a comet coming from the extra-solar space has been very likely discovered. Comet C/2019 Q4 Borisov has a speed and an orbital eccentricity strongly suggesting a interstellar origin. While...
We did some follow-up observations of the extraordinary object A/2017 U1, right now quickly traveling across the inner Solar System on an hyperbolic orbit, coming from the interstellar space. It was a very difficult...
Yesterday, we wrote about the discovery of an extremely interesting object, C/2017 U1, traveling in the inner Solar System along an hyperbolic orbit. The first announcement mentioned a cometary nature, potentially making it the...
Earlier today, the Minor Planet Center has announced the discovery of a new comet, C/2017 U1, by the PanSTARRS survey. It is quite faint and we would not talk about it, but it has...
