Emission Nebulae By: 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.
