NASA spots two galaxies crossing each other at 20 lakh kmph
NASA's Hubble Space Telescope has spotted two separate galaxies rushing past each other at about 20 lakh kilometres per hour. "The speed is most likely too fast for them to merge and form a single galaxy," NASA said. However, due to their "small separation" of 20,000 light-years, the galaxies would distort one another through the force of gravity while crossing.
