    Where scientists find galaxies, they find blobs of dark matter. Recently, astronomers discovered something unique - a ring of dark matter within a cluster of galaxies. Scientists believe the ring formed when galaxies smashed into one another. It's the first time scientists have observed dark matter reacting to gravitational forces, just like normal matter. Did Hubble find water vapor on a planet beyond our solar system? One scientist's theoretical model says it did. Scientists are always excited about the possibility of finding water on another planet, since it's one of the three things we believe is necessary for life, along with carbon and energy. Carbon and oxygen has also been detected already in the planet's atmosphere.
