Energy Star

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…

Star Formations Every star you see at night in the sky is bigger and brighter than our sun. Stars are born within clouds of dust and gas that is spread throughout most every galaxy. The life of a star includes many stages from nebulas to the mysterious black holes. Stars are responsible for the creation and circulation of heavy elements such as carbon, nitrogen, and oxygen. The elements characteristics are informally bound to the characteristics of the planetary systems that may consolidate…

Everything, Features, Intelligence By Jeff Sorensen You may have heard in the past few days that the NASA’s Kepler space telescope found that KIC 8462852 (an F-type main-sequence star located in the constellation Cygnus approximately 454 parsecs (1,480 ly) from Earth) noticed that lighting events observed at the star seemed very odd over the past few years. The dimming events happened so much so that scientists figured that it was too much to be caused by a planet. How scientists generally…

Hypernovas are the deaths of massive stars and the formation of a black hole. They are larger than supernovas and are believed to be the origin of long gamma ray bursts. This violent explosion happens in a matter of seconds, but produces more energy in those seconds than the sun produces in its entire 9 billion year lifespan. Not a lot was known about hypernovas until 2003 when a massive gamma ray burst reached earth. This was identified as a hypernova and photographed. In 1999 remnants of a…

Have you ever wondered how stars are formed, how massive they are, or even how they perish. 1. Well most massive stars are the shortest lived.2. A star's life expectancy depends on its size. 3.Most star’s take millions of years to perish. We should be learning about stars because stars are something that most humans don't know about, most don't know how they form, how they perish, or even how massive they are. Most massive stars are the shortest lived. A star's life expectancy depends on its…

infinite, we'd have an infinite number of stars light of the result The combination of the sky at night it should be clear to all.However, experience to the contrary. [1] Assumptions [edit | edit source text] If 1. the universe is infinite, 2. an infinite number of evenly spaced stars included, We can look in any direction, overlooking the star should be. The gloss is independent of the distance, so the night sky should be as bright as the surface of a star. We also need to do the above, if we…

that big star filled sky does as well. It doesn't just scare me, but it probably scares and excites scientists studying it all over the world. Since we only know a fraction of the inter-workings of the universe, there are many questions and things going on that we simply have no answer for yet. Dark Energy darkenergy-1 Dark Energy is the unknown force/energy that takes up around 70% of the universe. Sure, you look up and see billions of stars, but there's also the space between those stars…

Stars that are formed with different masses are thought to have different properties, such as low mass stars are more likely to turn into dwarf planets and high mass stars are more likely to turn into supernovas. Average stars like the sun usually become white dwarfs and the process of emitting its outer layers carry on until the stellar core is revealed which is known as a white dwarf. White dwarfs have the mass of a star but are the size of our planet which arose various questions along the…

Noah Yeasted A black hole is a large amount of matter in a small space. Black holes are one of the things that can be left over after a larger star dies. The other thing a larger star can become after it dies is a neutron star. A white dwarf is created after a smaller star dies. The only way for a star to become a black hole is if the star was 10-15 times more massive than the sun. The diameter of a black hole is approximately the diameter of New York City. A black hole’s gravitational pull is…

100 billion stars in our galaxy alone. Space is never ending filled with countless amounts of galaxies that we cannot even begin to understand. There are so many stars and so many lives. They have different sizes and shapes and they can turn into different things after they die based on their size and shape. The exact definition of a star is a fixed luminous point in the night sky that is a large, remote incandescent body like the sun, however, stars are much more than that. Stars are related…
