Leserbilder Astronomie: Comet Johnson approaches
© José J. Chambó
A year and a half after being discovered by Jess Johnson through Catalina Sky Survey telescopes and after travelling 750 million kilometers, the comet C/2015 V2 (Johnson) approaches the inner parts of the Solar System these days, being observable by means of binoculars. With astrophotography however it can be seen with much more detail, as in this widefield image in which you can see its dust tail departing toward northwest (to bottom right) and its more faint ionic tail to south toward the brightest star Delta Bootis at left.
