Emission NebulaeBy: Paul Jones and Antione Henderson

Characteristics They are usually high in temperature with a red glow from a

large amount of hydrogen. They are sites of recent and on going star formation &

because of this the hydrogen atoms seem to be mostly ionized.

This also causes them to glow as they receive light and energy from stars.

The Glow They glow different colors, if more energy is available more

colors show because more kinds of elemental atoms are being heated up.

This can help astronomers to deduce the chemical composition.

Life cycle of stars Stars begin as a proto-star enveloped in a cloud of gas. These clouds of gas are known as accretion disks and feed

the early star. The star then begins to condense and have controlled

nuclear fusion. After millions of years it suddenly “turns on” and spends the

majority of its life as a star. They will sometimes move away or they might even stay in

the nebula.
