"Everything scattered in the Andromeda system is very asymmetric and perturbed. It does appear that something significant happened not too long ago," Weisz said. "Our work has shown that low-mass ...

"It was actually a total surprise to find the satellites in that configuration and we still don’t fully understand why they appear that way." Dozens of dwarf galaxies swarming around the ...

From the lunar landing to the launch of the Hubble Space Telescope, here are some bold space missions in history.
