Explanation:
A mere 46 million light-years distant, spiral galaxy NGC 2841
can be found in the northern constellation of
Ursa Major.
This deep view
of the gorgeous
island universe
was captured during
32 clear nights in November, December 2021 and January 2022.
It shows off a striking yellow nucleus, galactic disk, and faint outer
regions.
Dust lanes, small star-forming regions, and young star clusters
are embedded in the patchy, tightly
wound
spiral arms.
In contrast, many other spirals
exhibit grand, sweeping arms with large star-forming regions.
NGC
2841 has
a diameter of over 150,000 light-years, even larger than
our own Milky Way.
X-ray images
suggest that resulting winds and stellar explosions create
plumes of hot gas extending into a halo around NGC 2841.
