Scientific Notation �Years ago scientist developed a short-cut to writing really BIG numbers and really small numbers. �It’s called…… Scientific Notation!

Scientific Notation – Reading Problem The Hubble Space Telescope orbits 353 miles above the surface of the Earth. NASA’S Hubble Telescope took pictures of a supernova that is 169, 000 light years away. Write this number in scientific notation. 169, 000 = 1. 69 x

What is a Supernova? � Among the billions of stars in a galaxy called the Whirlpool Galaxy, a massive star suddenly ends its life in a brilliant flash of light. � NASA's Hubble Space Telescope snapped images of the exploding star, 12 days after its discovery by amateur astronomers. � The exploding star was given the name : supernova 2005 cs. � Those photos were compared with Hubble images of the same region before the supernova exploded in the hopes of pinpointing the star that exploded.

Whirlpool Galaxy � Follow the handle of the Big Dipper away from the dipper's bowl, until you get to the handle's last bright star. Then, just slide your telescope a little south and west and you'll likely find Whirlpool galaxy.

A Supernova Explodes in the Whirlpool Galaxy

Let’s look at our word problem…. The Hubble Space Telescope orbits 353 miles above the surface of the Earth. NASA’S Hubble Telescope took pictures of a supernova that is 169, 000 light years away. Write this number in scientific notation. 169, 000 = 1. 69 x
