After researching some articles I finally found this one that couth my full attention. This article was released by NASA on 3/11/2013 and talks about the discovery of the closest star system found in a century. NASA’s made this discovery through there Wide-field Infrared Survey known as “WISE”. WISE discover a pair of stars that is set as the third closest star system to the sun. The founding of these two stars is the closest system founded since 1916. Bothe these two stars are called brown dwarfs witch can be define as stars that are too small in mass to ever become hot enough to ignite hydrogen fusion. Because of this they are very cool and dim and that makes them look more like a giant planet like Jupiter instead of a bright star like the sun. Kevin Luhman, an associate professor of astronomy and astrophysics at Penn State University, University Park, Pa., and a researcher in Penn State's Center for Exoplanets and Habitable Worlds states that these duo of stars are only 6.5 light years away. So close that television transmissions that was sent up in 2006 are arriving there now. These new starts will be a great place to search for new planets because they are so close to Earth that it makes it easy for scientist to see planets orbiting these dwarfs. This duo start system was named “WISE J104915.57-531906” simply because it was discovered by the infrared map obtained by WISE. This new duo is not far away from the second closest star call “Barnard’s” which is only 6 light years away and was discovered in 1916. The closest system founded to this day consists of “Alpha” and “Gentauri” they are set to be neighbors of the sun. Alpha was discovered in 1839 at 4.4 light years away and Gentauri in 1917 at 4.2 light years away. The principle investigator for the WISE satellite at UCLA “Edward Wright” aid that the main goal for WISE was to find the closes star to the sun and this new duo of stars are to this date the closest stars they have found with WISE data and...
