Rare 'eye-shaped feature' formed by galaxy collision
Using a radio telescope in Chile's Atacama desert, astronomers have observed a rare 'eyelid-shaped' feature of stars and hot gas, caused by two spiral galaxies, 114 million-light-years from Earth, grazing past each other. Such galactic 'eyelids' are seldom observed because they last up to tens of millions of years, a very brief moment in a galaxy's lifetime, an astronomer added.
