Astrophysics
GalaxyA galaxy is a massive,
gravitationally bound system consisting of stars, stellar remnants, an interstellar
medium of gas and dust, and an important but poorly understood component
called dark matter.
The Milky Way GalaxyThe Milky Way galaxy is a spiral galaxy consisting of
over 400 billion stars, plus gas and dust arranged
into three general components as shown to the
left: The halo - a roughly spherical distribution which contains the oldest stars in
the Galaxy, The nuclear bulge and
Galactic Center. The disk, which contains the
majority of the stars, including the sun, and
virtually all of the gas and dust
ACCRETION: This is the growth of a massive object by gravitationally attracting more matter, typically gaseous matter in an accretion disc. This is also a phenomena that resulted in the formation of many of the moons orbiting the planets in our solar system.
MOON: All moons have one thing in common – They are all “natural satellites held in position by gravity”
