Frage 1
Frage
What did Edwin Hubble do?
Antworten
-
Identify other galaxies, invented the first telescope and realize that galaxies were moving away from us.
-
invent the telescope and be an astronomer.
-
a famous baker and invented the raisin theory.
-
All of the above.
Frage 2
Frage
Galaxies are moving away from us.
Frage 3
Frage
Hubble believed that the universe is [blank_start]expanding[blank_end] in all directions.
Frage 4
Frage
What is electromagnetic radiation?
Frage 5
Frage
What does a spectroscope do?
Frage 6
Frage
A spectroscope measures wave lengths from the stars spectral lines?
Frage 7
Frage
When Edwin Hubble was studying the universe he saw the spectral lines from the purple side of the spectrum.
Frage 8
Frage
[blank_start]Red shift[blank_end] is when lights [blank_start]wave lengths[blank_end] become [blank_start]longer[blank_end]. That means that the object is [blank_start]receding[blank_end] away from us. Meaning that distant [blank_start]galaxies[blank_end] are moving [blank_start]away[blank_end] from us. When Edwin Hubble saw this, he discovered that the Universe was [blank_start]expanding[blank_end]. [blank_start]Cosmological Red shift[blank_end] is when lights wavelengths are constantly being lengthened. This is the main theory for how the Universe was born.

What is the Big Bang theory?
Antworten

Cosmic background radiation is:
Frage 11
Frage
COBE stands for: Cosmic Background Explorer.
Frage 12
Frage
One of the strongest pieces of evidence to support the big bang theory is [blank_start]Cosmic Background Explorer[blank_end]. A team of Scientists moped the universe by using a satellite they sent up into space. they mapped the [blank_start]background radiation[blank_end]. Red areas indicate hotter places. Blue areas indicate places that have had time to cool.
Frage 13
Frage
Wilkinson Microwave Antistropy Probe was sent up into space to make better predictions then the COBE.
Frage 14
Frage
Galaxies are clouds made out of dust and gas.
Frage 15
Frage
There are three types of galaxies: [blank_start]Spiral[blank_end], [blank_start]Elliptical[blank_end] and [blank_start]Irregular[blank_end]. Spiral Galxies are shaped like a pin wheel from above and from the side it looks like a plate with an orange in it. it contains mostly [blank_start]new[blank_end] [blank_start]stars[blank_end].
