The Big Bang Theory
The age of our universe
What is 13.7 Billion years old
The two characteristics that classify a galaxy.
Where all stars start out, in a cloud of gas & dust where they soon will be a protostar.
What is a stellar Nebula?
The number of planets in our solar system
8 planets
The cause of our seasons
What is The Tilt of the axis
Hubble's Law that our universe is constantly growing
What is Universal Expansion
Edwin Hubble developed this to classify the main types of galaxies
What is the Tuning Fork
The Spectral class of our star is a Class G. This is where 70% of stars are found in their life cycle.
What is a Main sequence
Kepler's 1st Law
The most outer layer of our sun.
What is the Corona
Found on the farthest edges of our universe, remnants of an old dying star. The oldest thing found in our universe
What is a Quasar
The galaxy that has no definite shape.
Irregular Galaxy
From a supernova, the unstable route the star can take where it implodes on itself.
What is a Black Hole?
Seated at the right distance and size away from our sun, this zone is where you will likely find habitable planets.
What is the Goldilocks Zone
It takes 171,000 years for a single photon to make it through this layer of our sun. Where UV Radiation is produced.
What is the Radiative zone.
Known for the shift in wavelength when an object is moving AWAY from us.
What is Redshift
The classification name for a Spiral that is older, more faint, and many arms
What is an Sc
The two characteristics for classifying stars.
What is luminosity & temperature?
Winter
The shortest day of the year is found on December 21st.
What is The Winter Solstice.
The leftover matter from the initial expansion that is spread out all over our universe. It can also be heard as a static
What is Cosmic Background Radiation (CBR)
The galaxy that sits between elliptical and spirals. Classified by the accretion disk that surrounds the central bulge.
What is an S0 or Lenticular Galaxy
A way to classify stars, where white dwarfs can be found at the bottom left corner, and red giants at the top right.
What is The Hertsprung Russel Diagram (H-R)
The number representing how elliptical that orbit is. (Not looking for a number)
What is eccentricity
Known as the red planet because of the iron found in the soil, it is also a terrestrial planet.
What is Mars
