Diagram Lab-Plotting the Stars Part I: Introduction 1) One method scientists use to measure the distance of the star is called parallax. Parallax shift is when closer stars shift positions against the farthest stars. In order for astronomers to measure that distance, they measure the distance of the shift, also considering the diameter of the Erath’s orbit. Then the angle of the parallax is measured. The smaller the angle of the parallax shift is, the farther away the star is from the earth…

It is classified as a Yellow Dwarf Star and has a surface temperature of 5,000 to 5,700 degrees celsius. But despite of this, there are many other stars in space that dwarf our Sun. The Sun also has an interesting history, from when it has been formed to the present time. The Sun is not the only star in the Milky Way. Another star close to Earth is Alpha Centauri C, also called Proxima Centauri. Unlike the Sun, Proxima Centauri is a red dwarf star. Every star has a spectral type. The Sun is a…

like all other stars in the galaxy, is also a star, but it differs from the rest due to the fact that the distance of the Sun from the Earth is less than a light year away…

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…

They could be confused with supernovae, but they surround a star. Supernovae are bright when they first are formed and normally spread a hundred light-years across (Arnett). The explosion could be seen in the sky but it would more like a star because of distance between the earth and the nova. Dark nebulas block light from surrounding stars and join with reflective and emission nebulas(Arnett). Reflective are normally blue in color but are not as big…

During their existence, stars form when the density of interstellar gas and dust, which form molecular clouds, reaches a certain point, and die by collapsing and turning into a white dwarf or a neutron star. Stars can fail and become a brown dwarf. Stars form when the density of the concentration of molecular clouds collapses and reaches a certain point. These regions are usually extremely cold and contain carbon and hydrogen. However, not all materials from the clouds form stars. Some of the…

is able to escape a black hole because of its strong gravitational pull. Black holes are the last great stage in enormous stars lifetimes that had been as big as ten to fifteen Suns. With zero force of gravity the black hole sucks up light from such a star. The light from the star then gets stuck in an orbit. Which that dark star then turns into a black hole. Matter and energy are pulled from the black…

ASTROPHYSICS Methods used to search for extrasolar planets Lucky Ruangsiri 24.02.2016 Extrasolar planets are planets that revolves another star apart from our solar system. The human race has found nearly 2000 confirmed extrasolar planets by the year 2016, and this has fuelled the search for extra-terrestrial life as we scour the universe for anything out there. How do we discover these planets that are light years away from the earth? An extrasolar planet detection technique is the…

used in astronomy for the evaluation of star composition light years away from Earth. Please provide detailed information. The spectrum of stars consists of bright lines and dark lines. These lines are produced when the star emits or absorbs energy at specific wavelengths. Emission line spectroscopy is used in order to find out the star’s colour spectrum. The spectrum can be found by using a visible light telescope or by collecting radiation that the stars emit and putting it through a…

Omega Centauri and Tarantula Nebula As opposed to the more short lived and less dense colonies of young stars that group up to create open clusters, globular clusters exist as far greater, spherical collections of aged stars that contain many low mass stars, sometimes numbering among the thousands. Globular clusters are more commonly found among a galaxy’s centre where the vast majority of stars are. It is thought that globular clusters arise from large gas clouds early in the creation of our…
