Binary star

The study of our stars is very important, astronomers study them to predict what will happen to our sun, which directly affects us. The first objects I observed were Albireo, two binary stars. They are about three hundredths to four hundredths and ten light years away. According to Stauffer Mark T from the American Psychological Association, “Albireo’s stunning colors provide a vivid contrast that has earned this double recognition as the most beautiful in the sky. Albireo is easily split using

formed when massive stars collapse under the weight of their own gravity (Schoolworkhelper Editorial Team). The nuclear fusion in younger stars creates a constant outward pressure from the core (“Black Hole Images, Facts and Information”). This balances the pull from the gasses in orbit around the core, keeping the star stable (Schoolworkhelper Editorial Team). Once a star’s life is nearing the end, and its gasses have almost all been used up in the nuclear reactions, the star will collapse inward

constellations useful? Or how can we find our nearby star this are some leading im going to try to answer in this essay. A constellation is the group of a bright star that forms shapes and patterns in the sky but are far apart in space. According to (Bennett, 2012) the start in a particular constellation appear to look closer to one another, but in reality, they are quite far apart because they lie at different distances from Earth. To measure the nearby star the astronomers use a technique called parallax

1. The brightness a star would have if it were at 10 pc from Earth is called its: A. Absolute Magnitude. a. Absolute magnitude b. Apparent magnitude c. Spectral type d. Center of mass e. Luminosity 2. A star with which of the following apparent magnitudes appears brightest from Earth? E. -1. 5 a. 6.8 b. 3.2 c. 0.41 d. -0.44 e. -1.5 3. What does a stars luminosity measure? A stars luminosity is measured by the apparent magnitude and absolute magnitude of the star and the amount of the light that

and April. It is near Canis Major. Canis Minor is being bordered by Monoceros and so as Canis Major. For Canis Major, Sirius is the brightest star in the sky and the fifth nearest star to the Sun.Sirius is a binary star. It is only about 8.6 light

Death of Stars and Their Detection After the core of a star has depleted all its hydrogen in fusion, it undergoes its final stages of its life, or in other words, its death. The process path of a dying star depends on its mass. Low mass stars, from about 0.4 up to 8 solar masses will evolve from a planetary nebula to a white dwarf. Stars with larger the 8 solar masses will form supernovae, than either a neutron star for intermediate stars (8-25 solar masses) or a black hole for high mass stars (greater

years. There are many questions such as how is a black hole born and how does a black hole grow. What is a black hole? A black hole is a dead star in outer space. It is where planets and stars disappear at. The gravity of a black hole is way too strong ( Aguilar 39). The black hole is a weird object in outer space and a black hole is formed when two giant stars or more collapse together and basically vacuum anything that comes near it ( Aguilar 39). It might be gases around the black hole. People call

that a star that was sufficiently massive and compact would have such a strong gravitational pull that not even

or any regular star. These can be seen throughout the entire galaxy, but it is hard for us to see because of the amount of dust that covers it blocks our view. Johannes Kepler was the last person to observe the last Supernova in our Milky Way galaxy. He discovered that phenomenon in the year 1604. A supernova is created when there is a change in a core or center of a star. There are only two ways that a change can happen in a star. The first way it can change happens in binary star systems. Those

In order to glean information about stars, astronomers analyze electromagnetic emissions, or the light, that reaches Earth. A spectroscope is basically a device that focuses a beam of light through a prism, which divides the light into characteristic colors that can then be seen using an eyepiece or screen. The resulting spectrum is used to determine the chemical composition of stars. The lines on the spectrum, or spectral lines, are associated with known elements. In 1868, an unknown element
