Using The Power of Galaxy Zoo To Do Real Astronomy

Scientists study the 'galaxy zoo' using Google Maps and thousands of volunteers, FECYT

"More than two thirds of spiral galaxies, including our own Milky Way, display a central bar that can extend for thousands of light years. These colossal elongated structures are made up of collections of stars and dark matter which are held together by gravity. Now a team of researchers from Europe and the USA have measured the bar length of some 5000 galaxies with the help of amateur astronomers. The most precise results (those obtained for 3150 galaxies) have been published in the Monthly Notices of the Royal Astronomical Society journal."
