1 What makes up the universe
MORE THAN MEETS THE EYE What makes up the universe Joseph Joachim Ranola and John Arbie Salunat Environmental Science 6

2 What makes up the UNIVERSE?
Something you CAN see Something you CANNOT see Nebulae

3 BARYONIC MATTER Something you CAN see 30-40 yrs. Ago: normal /ordinary matter or stuff that you CAN see” protons, neutrons and electrons The Universe composed of 4.6% atoms normal matter

4 Something you CANNOT see MORE THAN MEETS THE EYE The universe is composed mostly of stuff we can’t see DARK MATTER : Not reacted to light DARK ENERGY :  hypothetical form of energy  tends to accelerate the expansion of the universe.

5 There Are Five Kinds Of Nebulae
Emmision Nebula Reflection Nebula Dark Nebula Planetary Nebula Supernova Remnant

6 Emmision nebula Cloud of Ionized gas Most common source Protons

7 Reflection Nebula Interstellar dust Doesn’t create light
Not glowing plasmas Light source

8 Dark nebula Nonluminous nebula Dust and Gas Obscures light
Light source

9 Planetary Nebula Created when a star blows
Outer layers of gas expand into space Often the shape of a ring William Herschel Spherical clouds Round like the planets

10 Supernova Nebula Occurs when a high mass star reaches the end of its life Expanding shell of gas Originates from ionized gas

Composition Until 30 years ago, we thought all matter was “baryonic” matter (protons, neutrons, electrons). Now: 4.6% is baryonic matter 95% is non-baryonic.
