caused this point to become the universe we know today? The “big bang” theory is the popular explanation for where the galaxies‚ stars and planets came from. At the moment of the big bang‚ the hot‚ compact point began expanding like a balloon‚ rather than an actual explosion like most people believe. As the point of matter expanded‚ it cooled‚ contracted and formed stars and galaxies‚ like our solar system and the Milky Way. This suggests that big bang explains the expansion of space itself‚ which in

Physics & Theory • SETI o The Allen Telescope Array - The Allen Telescope Array (ATA) is a LNSD‚ also known as a “Large number of small dishes” array and is a new piece of technology to radio astronomy. What is different about it is that it is not one big dish‚ but a series of smaller dishes combined to make one larger one. - The ATA is highly effective and much cheaper for SETI to conduct more than one survey at once in the search of extra-terrestrials. - The ATA detects radio waves that can be

Black Holes and Their Mysteries Black holes are one of the most popular Hollywood science fiction topics also one of the most mysterious entities in space. Astronomers still have many questions regarding the darkest entity in space‚ black holes‚ but over time they began to analyze more and more clues and data‚ and are now able to explain what a black hole really is. Astronomers have come up with theories of the formations of black holes‚ the component of black holes as well as many other

Excerpt from “The Relative Motion of the Earth‚ Moon‚ and Sun” Lesson Plan Instructional Sequence Introduction o Write on the board: “Relative Motion” and “Motion of the Earth‚ Moon‚ and Sun”. o Begin by telling the class that you are going to “blow a hole in what they know” and fill it with new knowledge. Explain “there are some things in science you probably think you know‚ but you don’t know everything.” Ask‚ with a show of hands‚ “Who knows how the Sun‚ Earth and Moon move?”

During the next eighteen days‚ the Odyssey navigated through a dazzling array of nebulae as they left the Orion spur and entered the Perseus arm of the Milky Way Galaxy. In one area‚ in particular‚ the spirals of nebula clouds reminded Surina of Vincent Van Gogh’s Starry Night painting. On another occasion‚ she saw an electrifying nebula cloud in the shape of a cat’s neon green eye staring at her from a distance. In fact‚ the serpentine arms of the nebula clouds stretched throughout interstellar

to the formation of the Earth? The earth started off really hot and it was all compressed together. When the universe began to cool down and get bigger the elements were formed. Than hydrogen and helium formed our stars and galaxies than when the milky-way galaxy took place that is when earth and the rest of our solar system was formed. According to researchers the earth and other planets all formed at the same time. 2. What is the evolution of Earth’s atmosphere? In particular‚ what

Distant stars and distant galaxies aren’t completely featureless‚ but actually has specific spectral features. When we look at their spectrum‚ we can see an absorption of spectrum. Redshift and blueshift are two different terms that describe how the light changes as objects moves closer or further away from us. The reason that these two terms can describe whether or not objects moves closer or further away from us‚ is the fact that when a certain object in space is shifted to the red part of the

current universe. (“Big Bang Theory- An Overview”‚ n.d.) The Big Bang theory was introduced in 1927‚ Georges LeMaitre showed that religion and science‚ or at least physics‚ did not have to be incompatible. In 1929‚ Edwin Hubble discovered the galaxies were moving away at high speeds. The Big Bang was not like an explosion of a bomb going off‚ but an explosion of space within itself.
