What is Earth?
The closest star to Earth
What is the Sun?
This is the name for the Galaxy we live in
What is the Milky Way?
This is the force that keeps planets in orbit around the sun
What is gravity?
Famous telescope named after astronomer who discovered that there are more galaxies than just the Milky Way
Who is Edwin Hubble?
The hottest planet in the solar system
What is Venus?
This is a term for when a star catastrophically explodes and sometimes forms a black hole
This is a term for a large, gravitationally bound system that consist of stars, planets, back holes, gas, dust and dark matter
What is a galaxy?
This 17th-century scientist described the laws of motion and universal gravitation, which he used to predict the motion of the stars and planets.
Who is Sir Isaac Newton?
The age of the Universe
What is 14.5 billion years?

What is a neutron star?
The name of a galaxy, also known as M31, is the largest galaxy in our local group and is on a collision course with the Milky Way
What is the Andromeda Galaxy?
This term refers to the elliptical path one body in space takes around another due to the influence of gravity.
What is an orbit?
The Astronomer who proposed the heliocentric model in the 16th century
Who is Copernicus?
This is the largest volcano in the solar system
What is Olympus Mons?
This term refers to the "true" brightness of a star as if you were right next to it.
What is Luminosity?
This phenomenon is observed when galaxies are moving away from us at speeds proportional to their distance, providing evidence for the expansion of the universe.
What is redshift (or Hubble's Law)?
Proposed by Einstein, this theory describes gravity as a curvature of spacetime caused by mass and energy, and explains the perihelion precession of Mercury that couldn't be explained by Newton's laws.
What is General Relativity?
The effect of time slowing down when velocity gets closer to the speed of light
What is Time dilation?
This spacecraft, launched by NASA in 1977, is currently the farthest human made object from Earth
What is voyager?
This is the term for the boundary inside a black hole beyond which nothing can escape
What is the event horizon?
DAILY DOUBLE This is a group of thousands to millions of stars, bound together by gravity, that have a distinctive, somewhat spherical shape.
What is a globular cluster?
This is the term for the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
What is aphelion?
This hypothetical form of energy, which permeates all of space and tends to accelerate the expansion of the universe, was proposed as a reason behind the observed accelerating rate of the universe's expansion.
What is dark energy?
