Explanation:
Are your eyes good enough to see the Crab Nebula expand?
The Crab Nebula is cataloged as M1, the first on
Charles Messier's
famous
list of things which are
not comets.
In fact, the Crab is
now known to be a supernova remnant, an expanding
cloud of debris from the explosion of a massive star.
The violent birth of the Crab was
witnessed
by astronomers in the year 1054.
Roughly 10
light-years across today, the nebula is still
expanding
at a rate of over 1,000 kilometers per second.
Over the past decade, its expansion has been documented in
this stunning
time-lapse movie.
In each year from 2008 to 2017, an image was produced with the same
telescope and camera from a remote observatory in
Austria.
Combined in the
time-lapse movie,
the 10 images represent 32 hours of total
integration time.
The sharp, processed frames even reveal the
dynamic
energetic emission within the incredible expanding Crab.
The Crab Nebula
lies about 6,500 light-years away in the
constellation Taurus.
