An international group of astronomers spotted the star \u2013 VVV-WIT-08 \u2013 close to the Milky Way\u2019s centre, diminishing in brightness by a factor of 30, to the point it almost disappeared from the sky.<\/p>\n
While many stars shift in brightness as they pulsate or are eclipsed by another star in a binary system, it is incredibly unusual for a star to become dimmer over a period of several months and then illuminate again.<\/p>\n
The team have theorised that VVV-WIT-08 may be part of a new class of ‘blinking giant’ binary star system, where a giant star 100 times bigger than the Sun is eclipsed once every few decades by a currently unobserved orbital companion. The companion, which could be another star or a planet, is encircled by an opaque disc, which covers the giant star, resulting in its disappearance, then reappearance in the sky.<\/p>\n
