Ex. 6: The lifecycle of a star is determined by its mass. A typical star will follow the main sequence, become a yellow star like the Sun, and die as a Red Giant and then settle as a White Dwarf. A black hole is an area that has had gravity pull in on itself due to a supermassive explosion. Black holes need large stars to form. The Milky Way was formed in the aftermath of the Big Bang, and is around at the super dense core. There are billions of Galaxies spread out through the universe.
Ex. 7: The Big Bang Theory is a theory that states that the universe began with a super massive and dense collection of matter that contracted into itself, and then, in a matter of moments, exploded in an endless expansion into space. All matter, as we know it has been affected in this process. The universe as we know it is still expanding, and even moving faster, suggesting that expansion is speeding up and not slowing down. Open Universe is the idea that the universe is endless and there are no barriers or restrictions to its size. Big Crunch Theory is the theory that the big bang began with a collection of matter that crunched together, exploding outwards in the Big Bang. The Steady State theory is one that competes with the Big Bang, and proposes that matter Is constantly being created as the known universe expands. This...
Electromagnetic waves are energy waves produced by the oscillation or acceleration of an electric charge. They include radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. Their wavelengths in meters are: radio waves (0.1 to 1000), microwaves (1 x 10-3 ~ 1 x 10-1); infrared (7 x 10-7 ~1 x 10-3); visible light (4 x 10-7 ~ 7 x 10-7); ultraviolet rays (1 x 10-8 ~
Astronomy the moon will look 50 x as large as it did before. Kirchoff's laws describe three types of spectra: a) a "hot solid, liquid or gas," that is under high pressure, is known to give off "continuous spectrum"; b) a hot gas that is under low pressure produces a "bright-line or emission line spectrum"; and c) a dark line or "absorption line spectrum" is visible when a "source of a continuous
(Source: http://csep10.phys.utk.edu/astr161/lect/history/newtongrav.html). Assignment 2-1 -- a- Radiation may be considered information from space; different types of information from different sources. These are: 1) Light as a wave and particle, 2) Electromagnetism, 3) Cosmic Rays and 4) Ultraviolet radiation. Part 2-1-B- Light may be measured by telescopes; other space radiation by radio waves; x-ray machines may absorb cosmic and x-ray energy. Part 2-1-C- Stars and Planets emit electromagnetic; Sun emits UV, Electromagnetic and
The Moon is believed by many to have been part of the earth and that it was tore off as a result of an initial spin that was too great to hold the planet together. One of the prevailing theories was that involving an impact of large magnitude involving the newly formed Earth and a giant object of the size of Mars hitting Earth and blowing up material that
The evolution of the intermediate-mass stars is a good example of the process by which stars are born, live, and die. This star begins as a swirling cloud of gas that takes 100,000 years to collapse into a protostar. Hydrogen fusion begins in the protostar and causes the creation of a T-Tauri star which is a variable brightness star. This new star contracts for 10 million years until the
8. Over several years, several types of remarks corroborating the attributes of the cosmic microwave background radiations -- CMBR have been made. Most of them have been seen as direct observations, applying the same approach as that of the Penzias and Wilson. There exists in reality several observations advocated even earlier to that of the observations of Penzias and Wilson, however, the prominence of those were not acknowledged. 8. The
