Comet Leonard Before Star Cluster M3
Explanation: Comet Leonard is now visible to the unaided eye -- but just barely. Passing nearest to the Earth today, the comet is
best seen this week soon after sunset, toward the west, low on the horizon. Currently
best visible in the north, by late December the comet will best be seen from south of
Earth's equator. The featured image of
Comet C/2021 A1 (Leonard) was taken a week ago from
California,
USA. The deep exposure
shows in great detail the comet's
green gas
coma and developing
dust tail. The comet -- across our inner
Solar System and only light-minutes away -- was
captured passing nearly in front of
globular star cluster
M3. In contrast,
M3 is about 35,000 light-
years away. In a week, Comet Leonard will
pass unusually close to Venus, but will
continue on and be at its closest to the Sun in early January.

As usual clouds. Maybe I should find a new hobby. Astronomy gives me depressions these days.

I’m afraid Comet Leonard must be destroyed as it is blocking my view of Venus…

You’ve done it again Orin, those two cuties have to be siblings!
Interesting that they gave us a fresh photo on Saturday and a great one at that!

This is an astonishing image, and i wonder what was the equipment used and details of the capture.
