It takes a village to raise a child. Well, the same is true for finding what are called spaceworps. That's according to astophysicists who are calling for volunteers to aid in the search for gravitational lenses. Astronomical 1 objects are so massive that they bend light around themselves, appearing to warp 2 the fabric 3 of space. Aside from being wicked cool, this light-bending ability means gravitational lenses act like space-based magnifying glasses, which gives scientists a view of even more distant galaxies 4 and shades light on the make of the * themselves. The more they distort light, the more dark matter they contain. An national team of scientists launched the project in May and will be hosting a live google hangout June 5th, at 11 a.m US Eastern Time to call people to the hunt, more infos at C foundation.org. The questions can be submitted via email to the C foundation, or in Twitter using the hashtag C astro. If you miss the webcast, load a spaceworps.org to take part and learn how to spot the tell-tale signs of gravitational lensing and tell us * surveys. The images have already been scanned by computers but the scientists want your eyes on those guys.
