New images of comet C/2014 Y4 Atlas were obtained under good seeing conditions and they show a couple of main fragments and a likely a trailing cloud of debris. The image above comes from...
After one rainy night, we are back on comet C/2014 Y4 Atlas, seeing how its evolved. Several fragments are still visible in the image below. The image above comes from the average of 46,...
Thanks to good weather, we imaged C/2014 Y4 Atlas again and could clearly detect again several fragments, with evident changes in the brightness distribution. Here it is our image. The image above comes from...
After our observations suggesting the presence of fragments in the inner coma of this comet, we imaged C/2014 Y4 Atlas every night. In particular, tonight we observed at least three fragments, telling the comet...
We have been hoping to see comet C/2019 Y4 Atlas putting on a nice show up there later this season. Likely, this will not be the case, unfortunately. It looks like the comet’s nucleus...
We managed to analyze our 7 Apr. 2020 images of comet C/2019 Y4 Atlas, to follow-up the possible disruption event of its nucleus. The images used in the panel above come from the median...
We present a new image of comet C/2019 Y4 Atlas, lookingbrighter and brighter. Le’s hope it will amaze us next months. The image above comes from the average of 16, 300-seconds exposures, unfiltered, remotely...
We continue monitoring comet C/2019 Y4 Atlas, which hopefully will be visible by naked eye next April and May. While we remember that comets are unpredictable, we continue our coverage of C/2019 Y4. The...
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...
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...
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...
