2  A nebula is a cloud of gas and dust in space.  Some nebulas are regions where new stars are being formed, while others are the remains of dead or dying stars.  The word nebula comes from the Latin word for cloud.

3  A bright explosion of a star.  A supernova can produce the same amount of energy in one second as an entire galaxy.  http://www.youtube.com/ watch?v=tXV9mtY1AoI http://www.youtube.com/ watch?v=tXV9mtY1AoI  https://www.youtube.com /watch?v=L33zHRwI1jw https://www.youtube.com /watch?v=L33zHRwI1jw

4  A contracting mass of gas that represents an early stage in the formation of a star.

5  Material being ejected from a young star in two directions.

Supernova Supernovas are stars that are billions of times as bright as the sun. They become so bright because they are exploding. They don’t stay as bright.
