Explanation: How do we know that dark matter isn't just normal matter
exhibiting strange gravity? A new observation of gravitationally magnified
faint galaxies far in the distance behind a massive cluster of galaxies is
shedding new dark on the subject. The above detailed image from the Hubble
Space Telescope indicates that a huge ring of dark matter likely exists
