Object where the gravitational
attraction is so great that not even
light can escape
Black Hole
Brightness of a star as it appears
from Earth
Apparent Magnitude
Distances between stars and
Earth are measured with this unit
Light-years
This astronomer discovered that
there were other galaxies in the
universe and that they are moving
away from us, all in one night in
1929
Edwin Hubble
Chart that compares the true
luminosity (or brightness) of a
star to its surface temperature
Hertzsprung-Russell diagram (H-R
diagram)
Distances in solar system are
measured with this unit (not km)
Astronomical Units (AU)
Point at which Earth is closest to
the Sun
Perihelion
In the sun’s core this process takes
place which provides energy
Nuclear Fusion
This event takes place every 12
years and sometimes can affect
satellites
SolarMax (Solar Maximum)
A supernova that doesn’t become a
black hole may end in one of these
extremely dense stars
Neutron Star
Italian astronomer who used the
telescope to view the night sky,
and is considered the “Father of
the Scientific Method.”
Galileo Galilee
This colorful observation due to the
Doppler Effect proves that all
galaxies are moving away from each
other.
Red Shift
Fred Hoyle was responsible for
the name the “Big Bang” as he
mocked it because he was a firm
believer in this opposing theory
Steady State
Working for Bell Labs in 1978

its side
Uranus
This planet will be the first to be
swallowed by the sun as it enters
the red giant phase
Mercury
Name of moon's phases when the
lighted portion is decreasing
Waning
The moon is closest in
composition to this layer of the
earth
Mantle
Phase in moon's cycle when it is
between Earth and the Sun
New Moon
¾ visible portion of the moon
Gibbous
Due to the fact that the moon
rotates as it revolves around earth
this gloomy place does not exist
Dark Side of the Moon
