Often lauded as the father of modern cosmology, Edwin Powell Hubble made several significant discoveries that changed how scientists viewed the universe. Born in 1889, Hubble began his professional life as a lawyer, but returned to school after only a few years to obtain a doctorate in astronomy. Also developed a system to classify galaxies and he explained the redshift. and he met Einstein in 1931 and fixed mistakes

THE SUN VIRTUAL TOUR QUESTIONS
-Define: Sunspots - a spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surroundings.
Solar Active Region - A transient area of the solar atmosphere containing strong magnetic fields. Dramatic events can occur in these areas such as; sunspots and solar flares.
- Define and Temp: Chromosphere-
a reddish gaseous layer immediately above the photosphere of the sun or another star. Together with the corona, it constitutes the star's outer atmosphere.
Convective Zone- The convection zone of a star is the range of radii in which energy is transported primarily by convection. In the radiation zone, energy is transported by radiation.
Radiative Zone- An interior layer of a star through which energy is transported outward by absorption and re-radiation of photons originating in the hot stellar core.
Core- The central or innermost
Corona aura of plasma that surrounds the sun and other celestial bodies. The Sun's corona extends millions of kilometres into space and is most easily seen during a total solar eclipse, but it is also observable with a coronagraph
-How old is the sun? The sun is about 4.6 years at age.
-How long will the Sun last in its current state? This phase will last for about 100 million years
-Summarize the Sun's role in Climate Change
-Name two Solar missions and describe their goals-OSIRIS-REx
OSIRIS-REx is the first mission to bring pristine samples from an asteroid to study and analyze on Earth, to increase our understanding of planet formation and the origin of life.
Juno
Juno is a mission to Jupiter that will significantly improve our understanding of the origin and evolution of the gas giant planet, which will help us better understand our entire solar system.
-What is the Sun's made of (Composition)... 92.1% hydrogen and 7.8% helium.
