This stellar nursery cloud of dust and gas that begins the process of formation of objects in the universe.
Nebula
250
This is the innermost part of the sun where the release of energy begins.
Core
250
Much like solar systems, stars first from from this object made of free floating dust and gas.

In the immediate aftermath of the Big Bang, this process began causing the universe to expand.
Inflation
500
This is the process by which gravity allows larger objects to absorb the material of smaller objects.
Accretion
500
This is the main element that makes up the sun.
Hydrogen

This is the name given to the "prototype" of a star.
Protostar

Full Moon
750
The universe's size is currently doing this.
Expanding
750
This is the process by which objects form in an accretion disk.
Condensation
750
This is the process that combines hydrogen into helium.
Nuclear Fusion
750
Betelgeuse is classified as this type of star.
Red Supergiant

First quarter moon
1000
This is the "echo" of energy left behind after the Big Bang.
CMB (Cosmic Microwave Background)
1000
This is a swirling collection of dust and gas that will eventually become a solar system.
Accretion Disk
1000
This is the process that moves energy from the sun's core to the photosphere.
Convection
1000
Betelgeuse, and other stars like it, will end their lives in this spectacular show of explosive force.
Supernova

Jim Parsons, Kaley Cuoco, and Johnny Galecki starred in this CBS comedy that ran for 12 seasons.
The Big Bang Theory
1250
This is what forms at the center of an accretion disk.

These are the two forms of energy the sun releases.
Radiation and heat
1250
The sun is this type of star.
Average sized / yellow

Crescent moon
1500
This is the term, coined by Edwin Hubble, to show how objects are moving away from each other.
Red Shift
1500
This is the term given to the set of stars and planets that form from an accretion disk.
Solar System
1500
This is a massive release of solar energy that can cause damage to natural and man-made systems on Earth.
Solar Flare or CME (Coronal Mass Ejection)
1500
The final stage of a supermassive stars life can go one of two ways. Please name both.
Black hole or neutron star
