Comet C/2019 Y4 (Atlas): an image (21 Feb. 2020)
Discovered at the end of last year, comet C/2019 Y4 (Atlas) could have a name you will hopefully remember: it could become bright enough in May to put a nice show up in the...

Comet 289P/Blanpain: an image (23 Dec. 2019)
Late last December, we imaged the faint comet 289P/Blainpain, soon after its perihelion passage. Here we present our image. The image above comes from the average of three, 300-seconds exposures, unfiltered, remotely collected with...
2I/Borisov = C/2019 Q4, the first interstellar ever discovered: a new image – 8 Oct. 2019
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...
2I/Borisov = C/2019 Q4, the first interstellar comet is now official: a new image – 24 Sept. 2019
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...
C/2019 Q4 Borisov, the first interstellar comet ever discovered: a image – 17 Sept. 2019
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....
C/2019 Q4 Borisov: the (very likely) first interstellar comet ever discovered – 14 Sept. 2019
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...
(6478) Gault, the tailed asteroid: further evolution – 28 Mar. 2019
After our detection of an antitail feature, we did some follow-up observations of (6478) Gault, taking a deep image. The aspect evolved further, reflecting the changing, relative geometry, after the Earth crossed Gault’s orbital...
(6478) Gault, the “double” tailed asteroid: evolution – 25 Mar. 2019
After a couple of weeks from our previous visit, we imaged (6478) Gault again, under good sky conditions. We have found a quite different shape: we see now only one tail, with a possible...
(6478) Gault, the “double” tailed asteroid: a new image – 12 Mar. 2019
With the very clear sky we had last night, it was time to image asteroid (6478) Gault and its two tails again, to check their “health”. We have found them in good shape. The image...
(6478) Gault, the “double” tailed asteroid: a new image – 25 Feb. 2019
Exploiting a very clear sky, we made a deep image of asteroid (6478) Gault, now showing a narrow, dusty tail. We could observe its newer tail, too, as in the image below. The image above...
(6478) Gault, the tailed asteroid: new images – 14 & 24 Feb. 2019
More than two months after the its original announcement, we observed again the dusty tail of (6478) Gault. We have found this intriguing feature in good shape. The images above come from the average of...
Comet C/2018 Y1 Iwamoto and spiral galaxy NGC 2903: image and stunning video (13 Feb. 2019)
Comet C/2018 Y1 Iwamoto had a great meeting with the spiral galaxy NGC 2903. We could share this show with thousands of people via our live feed and here we present a stunning video...
Comet C/2018 Y1 Iwamoto: an image (13 Feb. 2019)
On the night of its closest approach to the Earth, we managed to observe comet C/2018 Y1 Iwamoto again, under good sky conditions. We detected its faint ion tail. Here it is our image...
(6478) Gault, the tailed asteroid: a new image – 7 Feb. 2019
We observed (6478) Gault again, the asteroid now showing a narrow, dusty tail. We see that not only the tail is still there, but we confirm a second, short structure recently reported, pointing to...
