Canis Majoris (or in English – Great Dog) is our galaxy’s largest known star. It was discovered March 7, 1801 by Jerome LaLande. It is known as a red Hypergiant.
This is an actual picture of Canis Majoris from the Rutherford Observatory Sept. 7, 2014.
If Canis Majoris was our sun it would extend beyond Jupiter’s orbit. Our own sun is but a pin prick on the surface of Canis Majoris. An airliner would take 1100 years to fly around the star.
The following clip will give you an idea of the immensity of the universe.

Have you ever seen the Helix Nebula before? This is a composite of pictures from Nasa’s Hubble telescope and Kitt Peak National Observatory. Yes, it is real, but the color was added by Nasa. I suspect for more impact, for a cover layout they were doing. Nasa, also, never gave it the name Eye of God. I wonder if the first man to visually see it had to be picked up off the floor. I know I would have passed out.
A nebula is a dying star. The Helix nebula is 650 light years away in the constellation of Aquarius. It’s a trillion mile long tunnel of glowing gases. If our sun died it would look pretty much like this.
Stars like our sun and Helix burn by turning hydrogen into helium by nuclear fusion. When the hydrogen is exhausted, the star starts burning the remaining helium at a greater temperature. When the helium is used up the star dies sending off gas layers around the hot core. The core is called a white dwarf and so dense that a teaspoon of white dwarf would weight more than a couple elephants.
The following is also a picture of the Helix nebula. You will notice a small dot in the center. This is the white dwarf. I’m not sure, but I think this one also has color added. It helps to see it better.

I can’t help but be amazed that God would put this in the heavens just so we would be reminded that He is watching over us.
“The heavens are telling of the glory of God; and their expanse is declaring the work of His hands.” Psalm 19:1
