Let's look up at the stars. Astronomy is a natural science that deals with celestial objects and phenomena that surrounds our atmosphere.
Experts say there are more stars in the sky than grains of sand on Earth's beaches. The largest one discovered is VY Canis Majoris, which is about 2,000 times the size of the sun. If it replaced the sun in our solar system it would extend up to Saturn.
Today, we celebrate astronomy. When it gets dark out, take a look at what wonderful objects are in the sky. If you have a telescope, blow the dust off of it and put it to good use.
