that contains the Earth is ceased to exist. Years of observations from the Hubble Space Telescope indicate the Andromeda galaxy is coming towards us at a speed of about 250,000 miles per hour and a head-on hit is imminent, Four billion years from now, it will be complete by about six billion years from now. Roeland van der Marel, an astronomer with the Space Telescope Science Institute in Baltimore, which operates Hubble, told the media. "The galaxies will collide, and they will merge together to

doubt the dramatic discovery made by Hubble, confirmed by Einstein’s equation, that the Universe is not eternal, static, and unchanging”. There has been a lot of debate of who should be credited for the discovery or prediction of the expanding universe. There is Alexander A. Friedmann, a Russian physicist and mathematician who suggested an

Hubble, who had access to the world’s largest telescope at the time, was able to make measurements of spectra from galaxies much further away than Slipher ever could. After several years of very tedious work, Hubble and his team at the Mount Wilson Observatory had accrued a considerable amount of spectral data for many galaxies with known distances. A linear

I Have A Theory The study of the universe as a whole is Cosmology. Although easy to label, it is not easy to explain. The foundation of modern cosmology can be described as an arrangement of observations, hypotheses, theories using science, technology, mathematics, physics, and analytics (to name a few) to strive for answers about our beginning, present, and future. Through time, many types of people have created stories, myths, and ideas of how we came to be. Until the nineteenth and twentieth

Studying the Stars: How the Telescope Changed Astronomy As long as humans have been able to see, they have looked at the stars with either with worship or with wonder. The earliest cultures of humanity created their deities from the heavens, most of which were seating upon the glowing specks of light that show through the black night sky. Humans only have a few senses that let them interact with and receive information from the environment, sight being the most useful. Trying to figure out what

Telescopes in Astronomy Cary Lingle PHY 107 June 25, 2013 Professor Worek Telescopes in Astronomy Peering out beyond the confines of the Earth was a daydream for early scientists. Staring into the heavens from the Earth limited the scientific community’s ability to study the cosmic bodies above the Earth’s surface. As curiosity grew to explore the Sun, moon, stars and far-reaching corners of the universe, creativity was sparked leading to the development of tools like a telescope to assist

Using the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), in a very wide-ranging survey, astronomers have found a distinctive relation between the existence of supermassive black holes that power high-speed, radio-signal-emitting jets and the joining history of their host galaxies. This meant finding more significance to the case of jets being the result of merging black holes. The astronomers studied a large selection of galaxies with very bright centers, known as active galactic nuclei

dark matter is the responsible substance that makes up most of the masses in the universe (found in galaxies, dwarf galaxies, and cluster galaxies). Dark matter is also the primary influence of gravitational pulls. The mysterious and magnificent space that seems almost empty to the naked eye has fascinated mankind for as long as history can remember. The universe seems empty because it is made up of gas which is primarily composed of particles such as protons, electrons, photons, neutrinos, and

The extent to which new, or complex, technologies impacted upon the project. The Channel Tunnel project would have been built two centuries ago if it was technically feasible. In 1802, the idea of a road tunnel was suggested to Napoleon during a brief peace between France and England. French engineer Albert Mathieu Favier gave Napoleon details of a scheme involving two tunnels, one which would be candle-lit for horse-drawn carriages and the second acting as a sort of drain to take away water seeping
