Star Cluster = A group of stars held together by gravitational attraction; the two chief types are open clusters (composed of from 12 to hundreds of stars) and globular clusters (composed of thousands to hundreds of thousands of stars). Also known as cluster. Universe = all of space and everything in it including stars, planets, galaxies, etc. 8.

Edwin Hubble studied the light spectra of 46 galaxies. He discovered all the galaxies were RED-SHIFTED. They were moving away from us. Galaxies far away were moving faster than the nearby galaxies. This is known as Hubble's Law. Scientists (Penzias and Wilson) have detected background static in signals from telescope antennas.

Consisting of a 0.85-meter telescope and three cryogenically-cooled science instruments, Spitzer is the largest infrared telescope ever launched into space. Its highly sensitive instruments give us a unique view of the Universe and allow us to peer into regions of space which are hidden from optical telescopes.

The two theories for the origin of the Universe in 1955 were: the stead-state Universe and the evolutionary theory of the Universe (also known as the Big Bang). In the steady state theory, the expansion comes from the creation of new hydrogen from empty space. In the Big Bang theory, expansion comes from the initial blast that started the Universe.

10. According to most scientists, the universe formed 13 to 14 million years ago. 11. All of the dark matter that forms the universe can be seen with a telescope. 12. The universe is structured by gravity found in clusters of interacting galaxies. 13. The universe is made up of superclusters that form enormous walls of galaxies in space.

As the universe expands, the galaxies are moving away from one another. 2. How can astronomers infer approximately how long the universe has been expanding? Astronomers can look at the red shift of the galaxies to determine the rate at which they are expanding. They use this information to work backward to determine the age of the universe.
