Stellar Beginnings
This giant cloud of gas and dust is where stars are born.
What is a nebula?
This stretching of light from distant galaxies suggests the universe is expanding.
What is red shift?
Earth belongs to this galaxy.
What is the Milky Way?
Spiral, elliptical, and irregular are classifications of these.
What are galaxies?
A massive star may explode in this dramatic event.
What is a supernova?
During this stage, a star spends most of its life fusing hydrogen into helium.
What is the main-sequence stage?
This faint radiation detected throughout space is leftover heat from the early universe.
What is cosmic microwave background radiation?
Collections of galaxy clusters form these enormous structures.
What are superclusters?
Light from an approaching object experiences this shift.
What is a blue shift?
If the core of a massive star is large enough, it may collapse into a black hole or this object.
What is a neutron star?
This force causes gas and dust in a nebula to collapse into a forming star.
What is gravity?
The farther away a galaxy is, the faster it generally appears to do this.
What is move away from us?
Galaxies bound together by gravity form this structure.
What is a galaxy cluster?
This law explains why planets speed up near the Sun and slow down farther away.
What is Kepler's 2nd Law?
White dwarfs slowly cool over billions of years into these.
What are black dwarfs?
This is the next stage our sun will reach.
What is the red giant stage?
This scientist discovered the first galaxy beyond the Milky Way.
Who is Edwin Hubble?
This substance is believed to make up most of the matter in the universe.
What is dark matter?
Pulsars are actually this type of stellar remnant.
What are neutron stars?
These stars are known for incredibly powerful magnetic fields.
What are magnetars?
This stage forms when gravity pulls gas and dust together before nuclear fusion begins.
What is a protostar?
The name of one of the two scientists that accidentally discovered cosmic microwave background radiation.
Who is Penzias or Wilson?
The Milky Way and Andromeda galaxies are expected to do this in billions of years.
What is collide?
A planet is discovered that orbits the sun once every 12 years. To the nearest whole number, the planet is this many times farther from the Sun than Earth is.
What is 5?
The outer layers expelled by a dying low-mass star create this glowing cloud.
What is a planetary nebula?
