Comet 62P/Tsuchinshan(紫金山), at the bottom in this image, already wears green. It will pass the perihelion next month. A galaxy on the upper left is NGC2903 in Leo.

AURORA ON WATER, AURORAS IN THE SKY, AURORAS EVERYWHERE! Taken by Markus Varik on October 19, 2017 @ Tromsø, Norway.
19th of October decided to come with a bang up in Northern Norway. The lights were out as soon it got dark enough and lasted the whole night, giving us plenty of time to take some cool photos. Supposedly were heading to Solar Minimum, but to be honest, me as a seasoned Northern Lights guide, have never seen such a strong beginning to the season. Long live Aurora!

M51: THE WHIRLPOOL GALAXY Image Credit & Copyright: Kerry-Ann Lecky Hepburn (Weather and Sky Photography)
Find the Big Dipper and follow the handle away from the dipper's bowl until you get to the last bright star. Then, just slide your telescope a little south and west and you'll come upon this stunning pair of interacting galaxies, the 51st entry in Charles Messier's famous catalog. Perhaps the original spiral nebula, the large galaxy with well defined spiral structure is also cataloged as NGC 5194. Its spiral arms and dust lanes clearly sweep in front of its companion galaxy (bottom), NGC 5195. The pair are about 31 million light-years distant and officially lie within the angular boundaries of the small constellation Canes Venatici. Though M51 looks faint and fuzzy to the eye, deep images like this one can reveal striking colors and the faint tidal debris around the smaller galaxy
