What's a light year and how do scientists use it?
A light-year is the distance light travels in one year and is used to measure very large distances.
True or False?
There are thousands of galaxies and millions of stars in each galaxy.
False! There are BILLIONS of galaxies & BILLIONS of starts in each galaxy
Why do some stars appear red, and others appear blue?
Due to their cooler temperature, some stars appear redder while others with a hotter temperature appear bluer in color.
