Science is so amazing, but it’s being de-funded around the world. We hope to make a difference with this video:

SCIENCE WARS – Acapella Parody (VIDEO)
Which field of science is the strongest? Physics, Chemistry, Biology or Math?
We have the disciplines battle it out in our new Star Wars inspired, acapella song.
THE GIANT MANATEE NEBULA Bright astronomical objects that are visible to the eye and optical telescopes are often nicknamed for their resemblance to earthly objects. A newly discovered view of a 20,000 year old supernova remnant is no different, resembling a beloved endangered species. W50 (or the Giant Manatee Nebula) is one of the largest supernova remnants ever viewed by the Karl G. Jansky Very Large Array (VLA). This large cloud, nearly 700 light years across, formed when a giant star exploded as a supernova around 20,000 years ago, spewing its outer gases flying outwards to form an expanding bubble. The remaining super dense relic of that giant star, very likely a black hole, feeds on gas from a closeby companion star which form a disk around the black hole. This disk and the black hole’s network of powerful magnetic field lines pull out charged particles out of the disk and channel them outward in jets that travel almost at the speed of light, acting like a giant railroad system. This pairing system of a black hole and its feeder star are both known as the SS433 microquasar. Over time, this awesome image of Florida’s “sea cow” will become mishapen, as the micro quaser’s jets will force their way through the expanding gas bubble of W50, punching bulges outward on either side of it. Until then, it will continue to be another wonder in the sky while providing more clues to fill the history of this giant cloud. –Sanj SOURCE:http://www.sciencedaily.com/releases/2013/01/130119185021.htm National Radio Astronomy Observatory. “Microquasar makes a giant manatee nebula.” ScienceDaily, 19 Jan. 2013.
