You are here. The orange dot in the above false-color drawing represents the
current location of the
Sun among local
gas clouds in the
spiral
Milky Way Galaxy.
These gas clouds are so thin that we
usually see right through them.
Nearly spherical bubbles surround
regions of recent star
formation. The
purple filaments near the Sun are gas shells
resulting from star formation 4 million years ago in the
Scorpius-Centaurus Association,
located to the Sun's lower left. The
Sun has been between spiral arms
moving through relatively low density gas
for the past 5 million years. In contrast, the Sun oscillates in the
Milky Way plane
every 66 million years,
and circles the
Galactic Center
every 250 million years.
