without looking at Earth’s atmosphere, which blurs pictures due to the atmosphere being constantly in motion. The telescope is 2.4 meters in length and has mirrors 94 inches in diameter. Some celestial objects that Hubble takes images of are stars and galaxies. Hubble has the ability to observe ultraviolet light that comes from the explosion of stars, and infrared light that comes from the formation of dust clouds. Both of these types of lights are blocked by the atmosphere, making it impossible…

wavelength of radiation due to the relative motion between the source and the observer along the line of sight.” (Slater) b. The Doppler Effect is important to astronomers because it gathers “basic information about the motions of planets, stars, and galaxies.” (Slater) 10. If you see a blue star, what does its color tell you about how the star is moving through space? Explain your answer. (Pages 49 – 50) a. By seeing a blue star, you can predict that a star is moving towards the Earth. As…

These live shorter than most other stars in the galaxy. The Planetary Nebula is consisting of glowing shell of gas, and plasma formed. Some of these exist in the Milky Way Galaxy. This is an important star because they play a key role in the chemical evolution. Massive Star : Any star that is larger than eight solar masses is a massive star. Massive stars are formed…

other uknown universes. Long ago, in this vast universe, a star was born and the goddess Galactis was brought into existence. Galactis was all alone in the cosmos for over a thousand years and eventually exploded. Her remains formed our milky way galaxy; the stars,…

The Life Cycle of Stars The life cycle of a star is an incredible, miraculous phenomenon that begins with just two elements: helium and hydrogen. The result is the all well known star that is seen twinkling in the night sky and also what lights up the day here on Earth. There are hundreds upon thousands of stars that take on many different sizes and colors. Depending on the size of the star from its birth, the star could take two paths at the end of its life: turn into a nebula leaving behind a…

produces in its entire 9 billion year lifespan. Not a lot was known about hypernovas until 2003 when a massive gamma ray burst reached earth. This was identified as a hypernova and photographed. In 1999 remnants of a hypernova were found in pinwheel galaxy M101. These remains and the events in 2003 helped scientists to begin to understand what a hypernova is and what it does. During a supernova a large star tears off outer layers leaving a new, colder and smaller…

dazzling array images that have awed and inspired the public.More than 45 terabytes have been collected. The 45 and more terabytes that have been collected,provides lights into the universe,from objects as close to the moon to the most remote galaxies,with incredible photos of supernovas and nebulas in between. In 1923 a German scientist Hermann Oberth first suggested that that a telescope could be launched into orbit to help overcome…

WHITE DWARF White dwarves (also known as degenerate dwarfs), are stellar remnants mainly composed of electron-degenerate matter and are white in color. The have a solar mass of up to 1.4, beyond this point, beyond this point, the pressure being exerted by the individual atoms is not able to hold back the gravitational pressure pulling it together The star would collapse down to a more compact object, like a neutron star or a black hole.. White dwarves are very dense, their average density being…

Part of your most recent plan was to be here now, you chose this human existence that you are currently experiencing, you pre- planned every detail of your life in order to gain the maximum learning and adventure, and you choose to exit when you have completed all the experiences you planned for yourself. The world away from this world (the universe) is not separate from us, it is not some far away mystery; it is a logical, functioning, populated, progressive, divine place! Much like here on…

the National Academy of Science urged the construction of such an instrument. The report said that a large orbital telescope would make a "dominant contribution to our knowledge of cosmology," by helping scientists study stars, measure distances to galaxies, and investigate the physics behind our universe.” -from http://history.nasa.gov/hubble/ “NASA” For decades, they spent all types of time and money for making this outer space telescope proposed by Spitzer. After the designing, building and…
