Explanation:
Comet PanSTARRs,
C/2017 T2,
shared this stunning telescopic field of
view with galaxies
M81 and M82 on May 22/23.
Of course, the galaxies were some 12 million light-years distant and
the comet about 14 light-minutes away, seen in
planet Earth's sky toward the Big Dipper.
A new visitor
from the
Oort Cloud, this
Comet PanSTARRs
was discovered in 2017 by the PanSTARRs survey telescope when
the comet was over 1 light-hour from the Sun, almost as distant
as the orbit of Saturn.
With a beautiful
coma and dust tail,
this comet has been a
solid northern hemisphere performer for telescope wielding
comet watchers this May, following its closest approach to the Sun
on May 4.
In this deep image
from dark California skies the outbound comet even seems to
develop a short anti-tail as it leaves
the inner Solar System.
