Astronomers have spotted a giant ‘blinking’ star toward the centre of the Milky Way, more than 25,000 light years away, phys.org reports. An international team observed star VVV-WIT-08 decreasing in brightness by a factor of 30, nearly disappearing from view. While many stars change in brightness because they pulsate or are eclipsed by another star in a binary system, it is very rare for a star to become fainter over a period of several months and then brighten again.
