A Galaxy Collision in NGC 6745
Explanation:
Galaxies don't normally look like this.
NGC 6745
actually shows the results of
two galaxies that have been
colliding
for only
hundreds of millions of years.
Just off the
above photograph
to the lower right is the smaller galaxy,
moving away.
The larger galaxy,
pictured above
, used to be a
spiral galaxy
but now is damaged and appears
peculiar
.
Gravity has distorted the shapes of the galaxies.
Although it is likely that no stars in the two
galaxies directly collided
, the gas,
dust
, and ambient
magnetic fields
do interact directly.
In fact, a
knot
of gas pulled off the larger galaxy
on the lower right has now begun to form stars.
NGC 6745
spans about 80 thousand light-years across and is located about 200 million
light-years
away.
