Stars
Many stars go along this path in which they start off blue, then go yellow, then red, until they finally collapse into a white dwarf.
What is the Main Sequence?
These type of galaxies have a flat disk, spiral arms, a central bulge, and a halo.
This is at the center of all Spiral Galaxies, and most other galaxies.
The name of our galaxy.
What is The Milky Way?
The Milky Way is this type of Spiral Galaxy.
What is a Barred-Spiral Galaxy?
This is formed when a star in the Main Sequence shells off its outer layers of gas, leaving its core as a white dwarf.
What is a Planetary Nebula?
This type of Galaxy is in a sphere or football shape.
What is an Elliptical Galaxy?
Made up of gas and dust, this is responsible for creating new stars.
What is a Nebula?
The sun is located here in the Milky Way.
What is halfway between the Galactic Center and the outer rim?
Light is able to travel in empty space because it is this type of wave.
What is an Electromagnetic Wave?
This type of star is INCREDIBLY massive, but it compact into a VERY small area. As such, it has an immensely powerful gravitational pull.
What is a Neutron Star.
This type of Galaxy is not a spiral, elliptical, or lenticular Galaxy.
What is an Irregular Galaxy?
These dozens to thousands of stars are grouped together inside the arms of Spiral Galaxies.
What is an Open Star Cluster?
This is how wide our galaxy (The Milky Way) is.
What is 100,000 lightyears wide?
These are the three largest galaxies in the Local Group.
What are the Milky Way, The Andromeda, and the Triangulum?
This is when a Neutron Star gathers enough material from nearby stars so that it can shine brightly from its magnetic poles, as well as spin rapidly and rhythmically.
What is a Pulsar?
This type of Galaxy has a disk but no spiral arms.
What is a Lenticular Galaxy?
This is how Planets are created.
What is "Heat creates Stellar Wind, which blows materials away from a newborn star. Some material sticks together and gets caught in the star's gravitational pull."
This is how many galaxies are in the local group.
What is 54?
How long it takes the Hubble Telescope to orbit the Earth.
What is 97 minutes?
This marks when a star officially stops being gas and dust and becomes a star
What is Nuclear Fusion?
This is the main type of galaxy that produces stars.
What is a Spiral Galaxy?
These millions to hundreds-of-millions of stars are usually old for stars, are clumped closely together, and make up the "halo" of our galaxy.
What is a Globular Star Cluster?
This is how many galaxies we estimate are in existence.
What is 170 billion?
An image from the Hubble Telescope is made up of this many images.
What is 48 images?
