Four pairs of what astronomers are calling impossible stars ââ¬â stellar twins in orbits so close they defy explanation ââ¬â have been found in our Milky Way galaxy, scientists say.
Astronomers using the United Kingdom Infrared Telescope (UKIRT) in Hawaii discovered the four star pairs, each of which is a binary system in which two stars circle each other in less than four hours. Until now, scientists thought that such twin-star setups couldn't exist.
