Do you know what Galaxies is?
Galaxies are sprawling systems of dust, gas, dark matter, and anywhere
from a million to a trillion stars that are held together by gravity.
Nearly all large galaxies are thought to also contain supermassive black
holes at their centers.
Just by looking at it you feel like you have been hypnotize by the
Galaxy🌠🥺

The first type of galaxies is SPIRAL GALAXIES, can also be recognized by their wide, flat disks of rotating gas
and dust.
Some spirals have wide flung arms like the above image of M51, while
others have spirals that are more tightly bound.
Fun fact: our very own Milky Way is a spiral galaxy, and it is
rotating at 168 miles per second. Now that is fast!
ELLIPTICAL GALAXIES are given their name because
of their oblong shape and lack of overall structure. Some are nearly
spherical, while others are shaped more like a cigar. They can range
in size from just a few light years across to being larger than our
Milky Way.
Another fun fact: while it is not entirely clear how they form, some
scientists propose that elliptical galaxies form as the result of
galactic collisions!
Speaking of galactic collisions,
PECULIAR GALAXIES are almost always the result
of one!
Galactic collisions are not as action packed as you might imagine.
Since galaxies are mostly comprised of empty space, it is unlikely
that any two given stars will collide during the event of a galactic
collision.
It is believed that peculiar galaxies compose 5 to 10 percent of all
known galaxies. So, it is safe to say that galactic collisions are a
common occurrence in our own universe!
IRREGULAR GALAXIES are galaxies that do not
fall under any of the three galaxy types mentioned above. These
galaxies tend to be small, dwarf galaxies that lack any
distinguishable shape. Many of these galaxies are companions or
satellites to larger galaxies.
A final fun fact: The Milky Way has dozens of irregular satellite
galaxies. Arguably the most famous one is the Large Magellanic
Cloud, shown above.
