Explanation:
Why does this galaxy emit such spectacular jets?
No one is sure, but it is likely related to an active supermassive black hole at
its center.
The galaxy at the
image center,
Hercules A, appears to be a relatively normal
elliptical galaxy in
visible light.
When imaged in
radio waves,
however, tremendous
plasma
jets over one million light years long appear.
Detailed analyses indicate that the central galaxy, also known as
3C 348,
is actually over 1,000 times more massive than our Milky Way Galaxy,
and the central black hole is nearly 1,000 times more massive than the
black hole at our
Milky Way's center.

Hubble Space
Telescope

Very Large Array (VLA) of radio telescopes
in
New Mexico,
USA.
The physics that creates
the jets remains a topic of
research with a likely energy source being infalling matter
swirling toward the central
black
hole.
