Stars

our galaxies, with many different characteristics and attributes, there is just one that stands out in the midst of all the others, Corot-7B. This planet is the smallest exoplanet that has been found outside of our solar system that orbits another star. This fascinating planet has a bright yellow color and is about twice the size of Earth and practically flows lava and rocks. This planet has temperatures ranging from 3,300 to 4,700 degrees Fahrenheit, literally making it anyone’s worst nightmare

light seen in the night. From Earth, the Milky Way appears as a band because its disk shaped structure is viewed from within. Galileo Galilei first resolved the band of light into individual stars with his telescope in 1610. Until the early 1920s most astronomers thought that the Milky Way contained all the stars in the Universe. Following the 1920 Great Debate between the astronomers Harlow Shapley and Heber Curtis and an observation by Edwin Hubble showed that the Milky Way is just one of many galaxies

For smaller stars when the nuclear fuel is exhausted and there are no more nuclear reactions opposing gravity the repulsive forces among the electrons within the star eventually generate enough pressure to prevent further gravitational collapse. The star then starts to cool and “die peacefully” comparatively, this type of star is called a white dwarf. When a very massive star about fifteen times the mass of the Sun collapses after it has exhausted

mad you need to understand how stars work. stars are massive collections of mainly hydrogen atoms, within a stars core, nuclear fusion causes hydrogen atoms get crushed into helium atoms which releases a ton of energy, this energy comes in the form of radiation, this radiation pushes against gravity which makes a nice balance between the two. Balance is key For the star to maintain this balance it must maintain fusion within the core, however with much larger stars, the

Brown Dwarfs shoots Jet and share star formation A brief Breakdown Just in case you were confused, brown dwarfs (http://coolcosmos.ipac.caltech.edu/cosmic_classroom/cosmic_reference/brown_dwarfs.html) refers to the objects in space that are too big to be planets but also too small to be a star. They are in between the two but are often thought that they form the same way stars do. In fact, they were just a theory, like many things in science, until one day one brown dwarf was discovered in 1995

meticulous cataloging of stars. The majority of the work had been done by a succession of underpaid and predominantly anonymous women known as “computers” or “Pickering’s Harem”. These included women such as Annie Jump Cannon, who did the crucial work in stellar classification, and Henrietta Swann Leavitt, who uncovered the correlation between the brightness of stars and their period of observation. In her papers and her thesis, Cecilia wrote about how elements in stars remained relatively the same

of habitable planets as they both are very Earth-like: Kepler 438b is said to be 70% be in the habitable zone of its star where as Kpler 442b has a chance of 97% be in the habitable zone (Technewsworld). This shows that both exoplanets are likely to have water in liquid state hence maybe able to obtain life. Base on the sizes of the two exoplanets and their distance from their star. Ian Sample, science editor of The guardian mentioned that both planets is likely to be having a rocky surface that resemble

The Universe and It’s Phenomena The universe is an unknown place. Most of it has not been explored. Some things are known, however. Scientists know a lot about things like the Big Bang and our Asteroid Belt. Some of the universe's natural phenomenons are yet to be discovered. This article will explain some of them and why they happen. In the year 1929, Edwin Hubble made a revolutionary discovery. He learned that the universe is expanding. He saw that the galaxies were each moving away

astronomers I knew used constellations to do so, as they could be used to point towards other stars, or in some cases (as with Orion) contained an object of interest -- the Orion Nebula. One winter night, looking at reference material, as the sky was clear for a change, I decided to compare my reference source with the night sky. It was in doing so that I met Orion for the first time (and Sirius, the "dog star", at his heels). The magic of being able to identify a constellation, that first moment of

other stars are too far, and it may take hundreds or thousands of years to reach them. However, as we will show, these arguments don’t rule out the possibility of interstellar travel. In contrast, there are possible method to travel to very far object in a person’s life. We don’t consider some possible but still very unrealistic technologies like twisting spacetime. Interstellar objects are very far. The closest star except the sun is Proxima, with a distance of 4.27 light years. Many stars have
