Intro Galaxies have a variety of shapes that ranges from ellipsoids to spiral galaxies. Spiral galaxies are made up of many individual stars. Moreover, the components of the spiral galaxies move relative to each other. For instance, a rotation curve of a rigid body measures the speed and the radius.
Now jumping ahead a few years to 1845 I now have twenty-seven stars, and still have red and white stripes. One year later I gained a state/star and I now have twenty- eight stars. In 1847 the stars were formed in a dimond and on each side there was one star. Now moving on to 1848 I had thirty stars on the blue background, in the upper right corner. Moving on to 1851-1861 I went from thirty-two stars to thirty-four.
Astronomy is an ongoing process because as time goes on, people just keep doing more and more with astronomy. For example, astronomy today is very different from the way some ancient civilizations used it. A lot of ancient civilizations used the stars to help them make calendars, help them know what season it was, help them know which way to go, and more. The stars even affected the ancient Egyptian’s religious beliefs. Some of our astronomy is somewhat based on some old astronomy, there’s even a study for how ancient civilizations use astronomy to maybe help us further advance our knowledge on astronomy.
It spreads out the colors of the light, allowing for the identification of elements by the bright lines visible in the spectroscope. Because of the differences in electron configurations, each element has a unique energy requirement for an electron to jump energy levels when excited, it also differs in the amount of energy it releases as it goes back to ground state, thus causing a change in color emitted. The spectroscope breaks down those individual colors and creates a "footprint" that is unique to each element. After observing the accepted patters for a set of elements, the observed spectrum patterns were compared and were matched with the most probable element based on emission spectra. Among the multitude of ways used to identify elements, flame testing and spectroscopy have proven to be a fast, reliable and efficient way of ascertaining the identity of various

Our neighboring galaxy is Andromeda Andromeda is about 2.537 million light years away. You can see andromeda from the naked eye on Earth all year round because of its brightness. For us it look at it, it will look like a fuzzy star. But only with special equipment, you will be able to see the full beauty of Andromeda. Scientists believe that one day both of our galaxy will combine and create one big galaxy.
Did you know that Annie Cannon was able to classify around a thousand stars a day during the peak of her career? This paper will be focusing on the life, career, and legacy of Annie Jump Cannon. Annie Jump Cannon was hired by Edward Pickering, and she worked as “Pickering’s assistant at the Harvard College Observatory” (1). After that, she was credited with coming up with an easy system that divided the stars into seven spectral classes. The spectral classes were as follows: O, B, A, F, G, K, M. Annie Jump Cannon’s career ended after forty years, but her work paved the way for women in the scientific community and continues to inspire fellow female scientists.
Astronomers Using ESO's Telescope have found the biggest and hottest double star that have parts actually overlapping each other. These two stars in the system VFTS 352 might be pummeling to its demise soon, because the two stars could merge and create a colossal star, or form a double black hole. These two stars are about 160,000 light-years from Earth. These stars are so close that the surface of each star are overlapping each other. This double star has a total mass of about fifty-seven times bigger than the Sun, but it also has the hottest surface temperatures rising above 40,000 degrees Celsius.
This could also be a reason people confused the North Star with the dog star. Around 2004 astronomers found a LBV 1806-20, which they believed was the brightest star, this took there mind off of Polaris (North Star) being the brightest star. This star is approximately 5-40 million times as bright as the sun. Astronomers estimated that this star was more than a million times the mass of the sun, but since this star is so bright is will burn out quickly within a million years.
Everything seemed so dark and yet the stars always shone even though engulfed in total darkness. Even though it is left in the dark, the star does not long to move and stays in place every night until the darkness comes again, as if saying “you do not bother me.” Somehow, even though millions of miles away, they filled me with hope. Maybe I could be like one of those
