A year later, using such an early refracting telescope, Galileo Galilei, an Italian physicist and astronomer, noticed the craters and mountains on the moon as well as what was later coined as the Milky Way Galaxy. Isaac Newton created the first 'practical' reflector in 1668, which included a small flat diagonal mirror to reflect the light to an eyepiece mounted on the side of the telescope. With time, telescopes became bigger and more sophisticated, and astronomers discovered more stars and galaxies. They were also able to calculate the distance between stars. Most of the large optical telescopes used for research today are reflectors.
This spacecraft was named after Galileo Galileo, the first modern astronomer. In the 1970’s a few other spacecraft’s, such as Voyager 1 and 2 and Pioneer 10 and 11, scouted Jupiter but they were unable to stay for an extended period of time and the amount of information they brought back to Earth was limited. Scientist wanted a spacecraft that could stick around for an extended period of time and gather more detailed information about Jupiter’s environment thus the idea of Galileo was formed. On October 18, 1986 the Space shuttle Atlantis, carrying the Galileo, was launched. Shannon Lucid was the Astronaut that performed the maneuvers that started this spacecraft on its long journey.
Originally, the program was called (CETI) Communications with Extra Terrestrial Intelligence, where it is now called (SETI) Search for Extra Terrestrial Intelligence. Over the course of the last two centuries there has been many more experiments searching for these life forms. Although SETI has almost no government funding, it has continued to better their technology and experiments. The technology they have begun to use has helped to disco... ... middle of paper ... .../topics/seti/what_is_SETI.html>.

That helps us with developing other X-ray telescopes in order to investigate more in our galaxy. It also showed us scenarios we never knew of before, like a galaxy cannibalizing another in order to gain in size. The extension of Chandra’s mission, based on its extraordinary work also speaks for it.

A lot of radio scientists or astronomers are considering the construction of a kilometer sized telescope, a humongous sized instrument that could be of use in SETI. Another cool thing about SETI is that optical searching’s and experiments are already widely increasing in number and even sophistication.
Black holes have a power far greater than our minds can imagine. This report will go into further discussion on these massive holes in space. Now, though, astronomers have uncovered a much better candidate for a black hole in our galaxy. It lies in the constellation Monoceros some three or four thousand light-years away. Monoceros was discovered in 1975, when it emitted a shower of light and x-rays.
It started back in 1959 with the help of two famous Cornell University physicists, Guiseppi Cocconi and Phil Morrison. Both claimed that it would be possible to communicate with other potential extraterrestrial life in space by the use of techniques used in radio astronomy (Heidmann 112). Together, they voiced their belief that if other "alien astronomers" elsewhere in the universe possessed radio telescopes, that it would be possible to converse between the two (Heidmann 112-113). A young astronomer by the name of Francis Drake agreed with the theories of Cocconi and Morrison. He proposed building a radio receiver in order to listen for waves of sound being transmitted through space.
They can also use it's capability for imaging enhancement, which allows you to zoom in on someone's nose hairs all the way from space. Robert Gossard (left) was one of the most integral inventors of the satellite. He was born on October 5, 1882. He earned his Masters and Doctoral degree in Physics at Clark University. He conducted research on improving solid- propellant rockets.
Scientist pre-Einstein could not comprehend how a wave such as light could hypothetically be influenced by a force such as gravity. However, when Einstein opened the door, black holes suddenly became a possibility, and it took a better half of a century before their existence could be proven, let alone monitored. Now, we have a better understanding of what black holes are, and how they come to be. Black holes are believed to be the result of the explosion of a very large star, at least 25 times larger than our own. When the star explodes, much of its matter is blown out into space, resulting in a supernova.
Almost everything today is linked in some way, to computers. Before computers were invented, very little was known about outer space. With the technology we have now, we are learning new things everyday. Computers are used to follow the paths of asteroids and predict their future movements. On 6 December 1997, a mile-wide asteroid was discovered by astronomer Jim Scotti, a member in the University of Arizona's Spacewatch group.
