“It’s Spirals All the Way Through Folks!”
SPIRAL VIEWS & CLUES
Known and lesser-know SPIRALS
are all turning above and below, in, on and all around us.
What and Where are they?
Here’s our 1st installment with
illuminating VIEWS and informative CLUES.
The Bubble Nebula, aka NGC7635

This Hubble Space Telescope image shows the galaxy UGC 12158.
It’s a barred spiral galaxy that scientists think bears a close resemblance to the Milky Way.

Artist’s concept of our Milky Way Galaxy.
Astronomers now believe the Milky Way galaxy has 2 major arms and many minor arms. The galaxy’s two major arms (Scutum-Centaurus and Perseus) can be seen attached to the ends of a thick central bar, while the two minor arms (Norma and Sagittarius) are less distinct and located between the major arms. Our Sun lies about halfway from the galactic center, near a small, minor arm (called the Orion Arm, or Orion Spur) located between the Sagittarius and Perseus arms.

NASA / JPL-Caltech / R. Hurt (SSC-Caltech)
Our galaxy is turning and it takes us about 240 million years to complete one cycle around its middle.
