PHOTOSPHERE The lowest layer of the Suns atmosphere that is also the visible part we see.
CHROMOSPHERE The middle layer of the Suns atmosphere that is hotter than the Suns surface.
CORONA Top layer of the Suns atmosphere that is millions of degrees in temperature and only visible during a solar eclipse.
SOLAR WIND Wind of charged particles from the Sun that flows out from the Suns corona.
SUNSPOT Dark spot on the Suns surface that usually occurs in pairs. Cooler than the surrounding surface and caused by the Suns magnetic field.
FUSION Process in a stars core in which atoms are joined together to form heavier atoms by extreme heat and density.
SPECTRUM All of the wavelengths of electromagnetic radiation arranged from shortest to longest.
BINARY STAR Two stars that orbit a common center of mass.
PARALLAX Apparent shift or change in position of an object caused by a change in position of the observer.
PROTOSTAR Hot, dense object at the center of a collapsing nebula that will become a star when nuclear fusion reactions begin.
The Sun What is the fate of our sun and other stars?
Chapter 29.1 Structure of the Sun Std 1e: Students know the Sun is a typical star and is powered by nuclear reactions, primarily the fusion of hydrogen.
The Sun. How Old Is Our Sun? Stars like the Sun shine for nine to ten billion years The Sun is about 4.5 billion years old, judging by the age of moon.
Objectives Explore the structure of the Sun. The Sun Describe the solar activity cycle and how the Sun affects Earth. Compare the different types of spectra.
Life cycle of stars Nebulae to supernova. Stars and radiation Stars are huge nuclear reactors that give off different forms of radiation (see below) all.
Chapter 2 Stars and Galaxies. Where are you? The Earth circles the sun The sun is one of billions of billions of stars. To measure distances between stars.
Exploring the Universe Chapter Energy From the Sun.
CHAPTER 10: CHAPTER 10: The Sun – Our Favorite (and Ordinary) Star.
Introduction: Transfer of Heat. Heat A form of energy associated with the motion of atoms or molecules. Transferred from higher temperature objects.

24.1 The Study of Light Visible light from sun is only a small part of whats emitted Electromagnetic waves –Radio waves, IR, light, UV,
The Sun Cycle of Solar Activity. The Sun sohowww.nascom.nasa.gov.
Our Solar System. Historical Astronomy – Wandering Stars Greeks watched the stars move across the sky and noticed five stars that wandered around and.
Protostars are difficult to observe because A. the protostar stage is very short. B. they are surrounded by cocoons of gas and dust. C. they radiate mainly.
Our Sun – Physical Properties. 109 Earths would fit across the diameter of the sun!! Diameter: 1,400,000 km, 864,000 miles 4.5 light-seconds 1,300,000.
The Sun: An Important Star The Suns Affects on the Earth The Sun is the only star in our solar system. It gives the energy needed by all the Earths.
Stellar Evolution What is the fate of the sun and other stars??
Chapter 17 The Atmosphere: Structure and Temperature.
The Sun in all its Glory Here is a look at the sun using many different scanning techniques, as well as different Lenses.
Stellar Evolution II. The Upper End of the Main Sequence: How massive can a star get? Larger clouds of gas (GMCs) tend to fragment into smaller ones before.
Copy and Answer in NB 1.What are the three layers of the suns atmosphere? 2.What produces auroras? 3.What are sunspots and why are they dark? 4.Describe.
Light and Color Susan Burke T.J. Sarlina. Main Injector, 2 miles around Tevatron, 4 miles around Fermilab.
Notes 30.2 Stellar Evolution Std 2d: Know stars differ in their life cycles and that may be used to collect data that reveal those differences Std 2f:
Our star, the Sun is a big ball of gas And it's 99 percent of our solar system's mass It's an average star in our Milky Way Warming the Earth every day.
How Does the Sun Affect Earth? Unit 1 Key Concepts 6th Grade GEMS Space and Science Sequence.
How does energy transfer through our atmosphere?.
1 Climate Change some astrophysical perspectives.
