Reference The Large Hadron Collider is the world's biggest particle accelerator. It's located at the European particle physics laboratory CERN, near Geneva, Switzerland.

Reference White dwarfs are hot, dense remnants of stars. They are the last observable stage of evolution for low and medium-mass stars including our sun.

Reference Mars' atmosphere is over 100 times thinner than Earth's and is primarily composed of carbon dioxide, nitrogen and argon gases.

Reference The temperature of Uranus averages minus 320 degrees Fahrenheit. Uranus holds the record for the coldest temperature ever measured in the solar system.

Reference Hale-Bopp was an unusually bright comet that flew close to Earth in 1997. Tragically, Hale-Bopp also influenced the Heaven's Gate cult's mass suicide.

Reference The distance to Mars from Earth constantly changes as they orbit the sun. The average distance between Earth and Mars is 140 million miles (225 million km).

Reference How big is the moon? Our moon is the fifth largest moon in the solar system, with a radius of 1,079.6 miles (1,737.5 kilometers).

Reference The cosmic microwave background (CMB) is primeval radiation emitted shortly after the Big Bang. Regarded as an 'echo' of the Big Bang, CMB fills the universe.

Reference The sun's temperature varies from around 27 million degrees Fahrenheit (15 million degrees Celsius) in the core to about 10,000 degrees F (5,500 degrees C) at the surface.

Reference Neil Armstrong was a NASA astronaut, aeronautical engineer and the first person to walk on the moon, on July 20, 1969.

Reference How long it takes to get to Mars depends on several factors including planetary position and available technology.

Reference We explore some of the best Hubble Space Telescope images of all time including nebulas, galaxies, planets and more!

Reference Redshift and blueshift describe the change in the frequency of a light wave depending on whether an object is moving towards or away from us.

Reference Find out how track the International Space Station from Earth and see where it is right now.

REFERENCE If you could journey through the cosmos' most monstrous objects, what tales — if any — would you be able to tell?

Reference Earth's atmosphere protects the planet and sustains life.

Reference The geocentric model is a debunked theory that the Earth is the center of the universe, with the sun and planets revolving around it.

Reference Stephen Hawking was regarded as a brilliant theoretical physicist. His work on black holes and the big bang are topics of popular books.

Reference NASA’s Lucy mission is the first to visit the Trojan asteroids. Lucy will help answer questions about the formation of the solar system.

Reference The Orion Nebula (Messier 42) is the nearest star-forming region to Earth, about 1,350 light-years away. It is located in the Orion Constellation, just below Orion's Belt.

Reference The Orion Constellation — named after the hunter in Greek mythology — is found on the celestial equator and is a prominent constellation in the night sky.

Reference There are a few good theories for a multiverse — an infinite number of parallel universes besides our own.
