energy from nuclear fusion, as they convert Hydrogen to Helium. As these massive stars begin to die once they’ve worn out their hydrogen and are now very old stars, they turn into giants/supergiants (old, large stars), resting just above the main sequence stars. This is where the “F” and “G” stars are located. The hotter they are, the brighter they are demonstrating the Sun being a G star. Next, the core contracts as the outer layers expand. This is leading to the explosion of stars eventually…

Stage Four: Protostar By this stage of the stars evolution, 100,000 years after the process began, it can now be plotted on the Hertzsprung-Russell diagram, which is used to compare the many different stars. Although it is still not fully formed, we are able to determine the type of star it will become based on its luminosity and temperature. In the nucleus of the condensed cloud, which could now fit within the orbit of Mercury at less than 58,000,000 km wide, electrons and protons are ripped…

12.5 hours. The diameter is about 2.2 million miles, which is 2.5 times the Sun, the temperature is approximately 17,000 F (9,500C), the luminosity is about 40 times the Sun’s size, and the star type is is a white main sequence star, so it is in A class. Since it is a main sequence star, it fuses hydrogen into helium in its core, The Vega star is also known as the Alpha Lyrae and is in the Lyra constellation. It is a blur to white star and has a radius of 1.1 million miles, 2.5 times larger…

An astronomical star catalogue lists stars by number according to different criteria (such as their magnitude), which can provide insight into the positions of stars, how they change over time, and even the history and culture of the astronomers who create these catalogues. As early as the 2nd millennium B.C.E, star catalogues have been kept (Van der Waerden); they can be seen all over the world and across cultures, increasing in breadth over time as the technology of telescopes advanced and…

swirling’ to hole star being rotated around a fixed point of gravity also known as black hole. This movement generated heat which intern emits EM waves which re detected by special instruments called ‘’black hole hunters’’. An instrument aboard the NASA Hubble Space Telescope, called the Space Telescope Imaging Spectrograph (STIS), which was installed in February 1997 is Hubble’s main "black hole hunter’’. It is responsible for many black hole discoveries such as the black hole in the galaxy…

our direction, exactly what it was shown like in the clip. Atlantis had a worn out, scratchy exterior, and was tilted down to the right side for the tourists to observe the inner hollow shell. Also to the right in that same room was a replica of the Hubble Space Telescope. I already had some prior knowledge of the legendary telescope, though I never knew how gigantic it was. “I guess, you never know how big things are until you see them in person,” I mumbled to myself. There was a narrow…

Space-based photometers such as the Hubble Telescope and Kepler have already been launched into orbit around Earth. These telescopes were some of the first catalysts in the discovery of exoplanets. As of December 3, 2015, scientists have confirmed 1,916 exoplanet candidates as true planets (“NASA Exoplanet Archive”). Kepler and Hubble use radial velocity observing methods, which utilize the transit method and Doppler shift of a star…

instructor. He has flown well over 160 different types of aircraft and has made more than 800 free falls, 100 of which were experimental falls used to study human aerodynamics. The story that Musgrave is known best for is commanding a mission to repair the Hubble Space Telescope. He led the eleven day mission and completed three out of the five spacewalks himself, successfully fixing the…

Through research an understanding is gained, and the researcher is able to better comprehend the capabilities of their decided to device. Once this step is achieved, it is next part of the process to review images produce by similar resources via the Hubble Space Telescope. The researcher is to choose one of the images provided by the center. After reading the explanation of the image, questions need to be reviewed as well as a description of the images contents. As the final portion of the lab,…

-There we had to go through a simulation of fixing the Hubble Telescope and we were given a problem. We were having a successful mission when the problem came. Our team was given one of if not the hardest problem. We were hit by an asteroid losing many functions and losing orbit. I was the commander at the time…
