Bright Star

astronomer Mercedes Richards. This astronomer love stars and studying on the history about them. When she was a little girl that’s all her farther would take her out to see was the beautiful stars floating in the midnight sky. But there is a certain kind of star Mrs. Richards studied in her system which is called Binary stars name after a prototype. She always makes sure people around the world understand the socialization with her and the stars and the descriptions on them. Astronomer Mercedes…

she discovered 300 variable stars and invented her own system of classification, which became the universal standard, she listed around 350,000 stars. Annie Jump Cannon died on April 13, 1941 in Cambridge, Massachusetts at the age of 77. Annie Jump Cannon’s father was Wilson Cannon, a Delaware shipbuilder and state senator, her mother was Mary Jump, Annie was the oldest daughter. She was first taught about constellations, which became the main source of interest to stars for Annie, by her…

the night and what do you see? Millions of twinkling lights, also known as stars. Stars are one of the most popular astronomical objects and represents the building blocks of galaxies. A star is defined as a vast ball of gas held together by its own gravity. The nearest star to earth is the Sun. Similar to a living organism, stars have a life cycle in which they are born, they develop and grow, and eventually die. Stars begin as a vast cloud interstellar dust (mostly carbon or silicon) and…

the radiation of ordinary stars, AGNs are prominent across the entire electromagnetic spectrum. Thus, astronomers needed to look beyond the visual regime to see their full potential. Recent technological advancements, such as satellite deployment, have enabled astronomers to explore energies once unattainable. In addition to the showing in a wide range of energies, AGNs also change in brightness on time scales from minutes to decades. It's no wonder then that some stars once thought to be…

collapsing star, these are formed from very intense explosions in distant galaxies. GRBs are the brightest known electromagnetic events in the universe. They can last just a few milliseconds, or hours. The burst is often followed by an afterglow, which is emitted at longer wavelengths. We have been able to learn a lot of what we know about GRBs from afterglow. We can measure how far away the galaxy that the GRB came from is by the afterglow. GRB’s are commonly formed when a high energy star…

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…

group of stars movement that orbits an area in a space. In other words, when gas enters stellar black hole from a companion star, the gas twists inwards, heating at a very high temperature and producing huge amounts of radiation that can be noticed from earthbound and earth-orbiting telescopes. Locations that black holes can easily be found have been identified. One likely area is at the middle of galaxies. At this region the concentration of stars increases the possibility of larger stars to…

The Kepler Telescope main instrument is a photometer. This instrument measures the brightness of stars within its field of view. Data is then gathered and analyzed to detect any variations or deviations of light which is caused by the transits of plants of host stars. These dips in light help in detecting planets in "Habitable Zones". Gliese-581g The planet Gliese 581g is one of six possible planets in the constellation Libra. This exoplanet was discovered in late September 2010. The main reason…

today. Those two things are hydrogen and helium. The temperature it normally stays at is around 15 million degrees celsius. Which is enough heat to reach to are planet earth this day. The sun tends to be a bomb with this much material packed into one star. But yet gravity keeps it together. As time goes the earth will be consumed by the sun. The sun grows bigger and bigger every year. Which will eventually expand to a certain point then earth wouldn't exist.…

the faint glow of a star. Seeing the first star that night, you make a wish and remember the first time you saw one. You still wonder what that speck of light is—How it got to be up there, why it sometimes is so bright and other times so faint, and how it plays an important role in the universe. The street light flickers on above your head, snapping you out of your reverie and reminding you that you still have an essay to write. You sigh, sit up, and walk to your house, the stars quickly…
