Explanation:
Cataloged as M1, the Crab Nebula is the first on
Charles Messier's famous list of things which are
not comets.
In fact, the Crab Nebula is
now known to be a supernova remnant, an expanding
cloud of debris from the death explosion of a massive star.
The violent birth of the Crab was
witnessed by astronomers
in the year 1054.
Roughly
10 light-years across,
the nebula is still expanding
at a rate
of about 1,500 kilometers per second.
You can see the expansion by
comparing these sharp images from the
Hubble Space Telescope and James Webb Space Telescope.
The Crab's dynamic, fragmented filaments were captured in visible
light by Hubble in 2005 and Webb in infrared light in 2023.
This cosmic crustacean
lies about 6,500 light-years away in the
constellation Taurus.
