Dr. Brian May, astrophysicist, CBE

Brian May is an astrophysicist who pursued a career in music. He is the guitarist for the rock band Queen and he is more famous for writing “Fat Bottomed Girls”, “We Will Rock You”, & “Who Wants to Live Forever” than for anything he wrote while obtaining his Astrophysics degrees.  Brian was popularizing Galaxy Zoo on his blog (Galaxy Zoo is an online project which seeks public help in classifying vast numbers of galaxies.  A Dutch fan, Hanny van Arkel (a schoolteacher by trade), became interested in the project and started working on the site when she spotted a huge weird glowing green thing below spiral galaxy IC 2497.  She presented her findings to professional astronomers, who were also perplexed by the ghostly shape.  They duly named the object in her honor “Hanny’s Voorwerp” (which is Dutch for “Hanny’s thing”).

So what is Hanny’s Voorwerp? The leading theory is that the supermassive black hole in the center of IC 2497 created huge jets of energy and gas as it (messily) devoured great masses of matter at the center of that galaxy.  These esoteric plumes interacted with an unrelated stream of gaseous matter hundreds of thousands of light years long (which is longer than our galaxy).  The thin clouds of glass then fluoresced like a krypton sign or a Scooby-Doo ghost.

Thanks Brian May and Hanny! This is one fancy voorwerp.
