Consider Hubble's Discovery of the expansion of the universe, how is is
interpretation justified? - ANSWER: Distant galaxies are moving away from us faster
than nearby galaxies with a velocity proportional to the distance which means the
farther away the galaxy, the faster it is recieding
how does this tie in with olbers paradox? - ANSWER: Olbers paradox says the sky
should be infinitely bright with stars. The universe having finite age resolves the
paradox. With finite age there is a finite distance out to which we can observe, light
from more distant stars hasnt had enough time to reach us.
How does this tie into CMBR? - ANSWER: the baby universe was small, hot, and
dense. Hubble's law shows that the universe went from very small hot and dense to
an immense universe that is ever expanding between galaxies.
Spectroscopy - ANSWER: tells us what elements are present in stars
What we can identify through spectroscopy - ANSWER: we can identify the atoms by
the colors of light they absorb
we can use the colors and temperatures found to assign stars to their.... - ANSWER:
spectral class
Blackbody radiation - ANSWER: the radiation given off by an non-reflecting object
photon energies and numbers of them are given through - ANSWER: black body
radiation
Why is the solar system flat - ANSWER: gravity pulls the cloud into a dense ball,
angular momentum spins the cloud and makes the solar system flatten into a disc
The Conservation of Angular Momentum - ANSWER: spinning things will resist
stopping their rotation
planets are spheres because - ANSWER: gravity pulls material center to its core and it
rotates to hold everything in
, Kuiper belt - ANSWER: chunks of ice, boulders, and planetesimals formed out of rock
and ice past neptune
asteroid belt --> - ANSWER: jupiter
kuiper belt --> - ANSWER: neptune
Absolute Magnitude (Mv) - ANSWER: intrinsic brightness (if all stars were 10pc away)
Accretion - ANSWER: the process where small particles become large particles
Angstorm - ANSWER: 1 ten billionth of a meter
Aphelion - ANSWER: the object the farthest distance from the sun of all of the
objects orbiting it
Apparent Magnitude - ANSWER: the brightness at visible wavelengths of a star
AU - ANSWER: the average distance from the sun to earth
Black Body Radiation - ANSWER: the radiation given off by a non reflecting object
Black Hole - ANSWER: corpse left by a very massive star, very strong force of gravity
that is so dense that not even light can escape it
CCD- Charge Coupled Device - ANSWER: light sensitive computer chip used to
convert light into an accumulation of charges.
Used for spectroscopy and photometry
chromosphere - ANSWER: a reddish gaseous layer immediately above the
photosphere of the sun or another star. Together with the corona, it constitutes the
star's outer atmosphere.
CMB- Cosmic Microwave Background - ANSWER: the radiation that reaches us from
all directions of the cosmos
Condensation sequence - ANSWER: the order in which chemical compounds
transition from the gas into the solid phase, following the condensation temp of
each compound
Dark Matter - ANSWER: matter that reveals its presence through gravitational
effects, but cannot be detected directionally by any known means
Density - ANSWER: the amount of matter in a certain volume; measured in number
of particles per cubic length
