Evolution of Stars
Galaxies and the Universe
100
This causes the apparent movement of stars in the night sky?
What is the Earths rotation?
100
This changing feature of the sun is responsible for causing radio blackouts and malfunctions in orbiting satellites.
What are Coronal Mass Ejections?
100
This Changing feature of the sun interacts with the Earth's magnetic field and create the Auroras.
What are Solar winds?
100
Stars form deep inside this, which is a fancy name for a large cloud of gas and dust.
What is a nebula
100
This is a huge collection of stars.
What are galaxies?
200
This is the average distance between the Earth and the Sun It measures about 150 million Kilometers.
What is an Astronomical Unit (AU)?
200
This process causes a star to glow, making it visible?
What is nuclear fusion?
200
Although there is no surface to a star, this section is often mistaken as being the surface.
What is the photosphere?
200
This is what causes the densest parts of the nebula to collapse.
What is gravity
200
Matter that emits no light at any wavelength.
What is dark matter?
300
This number represents how many constellations astronomers developed to map the night sky?
88
300
This is the closest star to Earth.
What is the sun?
300
The wide, outermost layer of a star's atmosphere.
What is the corona?
300
An enormous explosion that destroys a star.
What is a supernova?
300
Spiral, Elliptical, and this make up the 3 major types of galaxies?
What is Irregular?
400
By knowing this, and a stars apparent magnitude, scientists can calculate the star's distance
What is luminosity?
400
Nuclear fusion creates this, in the form of light.
What is energy
400
This orange and red colored layer of a stars atmosphere sits above the photosphere.
What is the chromosphere
400
These regions form due to gravity collapsing the nebula. These regions contain enormous amounts of thermal energy.
What are protostars?
400
This theory states that the universe began from one point billions of years ago and has been expanding ever since.
What is the Big Bang Theory
500
Anyone up for a road trip? Catch a ride on this and you will travel about 10 trillion Kilometers in a year?
What is light?
500
This zone is a shell of cooler hydrogen that sits above the Stars core.
What is the radiative zone?
500
These are regions of strong magnetic activity on the sun. They are cooler than the rest of the photosphere and appear as dark splotches on the sun.
What are sunspots?
500
An object whose gravity is so great, no light can escape?
What is a black hole?
500
When light shifts to a different wavelength.
What is a doppler shift
