What are supermassive black holes?
masses that have 3-5 solar masses
masses ranging from millions to billions of solar masses
How do we know black holes exist if we cant see them?
We observe Jets, weird motion, and falling objects into the black hole.
We observe Transfer of material, nebulas, and white dwarfs.
We observe no change in gravity, falling objects into a black hole, and redshift.
We observe many planets, jets, and cocoon nebulas.

TRUE
FALSE

galaxy
solar system
planet
constellation
Huge glowing balls of gases made up of mostly hydrogen and helium are called ____________.
hemisphere
stars
planets
comets
The southern hemisphere uses what constellation as a reference and starting point
Southern Cross
The northern hemisphere uses what constellation as a reference and starting point
Ursa Minor
Andromeda
In which directions do stars rise and fall?
Why do we see different constellations during different times of the year?
the stars that make up constellations form different patterns throughout the year
the stars move out of view of the Earth in different seasons
the stars get closer to and farther from the Earth during the year
the Earth revolves around the sun giving us a different view into space each season
Which of the following causes seasonal changes on Earth?
Choose all that apply.
the Earth rotates on its axis
the Earth revolves around the sun
the Earth is tilted on its axis
the Earth moves closer to and farther away from the sun throughout the year
the moon revolves around the Earth.
The constellation Leo is visible in the northern hemisphere in the summer, but not the winter. Which explains why we can't see Leo in the winter?
the constellation Leo moves to another solar system during the winter
the stars that make up Leo change positions and form a new pattern in the winter
during the winter, Leo is located on the daytime side of the Earth, so we can't see it
during the winter, Mars blocks the constellation Leo so we can't see it
Why do we see different constellations during different seasons?
The constellations move.
Some of the stars disappear.
We are looking out at different parts of the galaxy.
