A rendering of the 'Whirlpool Galaxy'
The M-51, or Whirlpool, Galaxy is one of the most studied galaxies in the universe, but Case Western Reserve University researchers have found a never-before seen cloud of hydrogen gas associated with the galaxy.

Physics professors discuss how gravitational waves may be able to show us the universe

How gravitational waves could give us a glimpse of the invisible universe

Popular Mechanics: Glenn Starkman, Distinguished University Professor and co-chair of the Department of Physics, and Craig Copi, senior instructor of physics at the College of Arts and Sciences, discussed how gravitational waves could someday be used to probe distant matter in the universe. “People have always been interested in measuring something new,” Copi said. “This gives us a completely new way of viewing things in the universe.”
