Astronomers have found what they name a large “blinking” star in direction of the middle of the Milky Means galaxy. The star known as VVV-WIT-08, and it’s 25,000 light-years away from Earth. The mysterious star was noticed within the sky because it decreased in brightness by an element of 30, making it nearly disappear from the sky.
Astronomers say that it’s not unusual for stars to vary in brightness as they pulsate or are eclipsed by one other star in a binary system. This can be very uncommon for stars to develop into fainter over a number of months after which brighten once more. Astronomers imagine VVV-WIT-08 might belong to a brand new class of “blinking big” binary star system the place a large star that’s round 100 instances bigger than the solar is eclipsed as soon as each few many years by an unseen orbital companion.
The companion orbiting the star may very well be one other star or presumably a planet surrounded by an opaque disk that covers the enormous star inflicting it to vanish and reappear within the sky. Research co-author Dr. Sergey Koposov stated that it’s unimaginable that we noticed a darkish, massive, and elongated object handed between us and the distant star. For now, all scientists can do is speculate on what the item passing between us and the star could be.
VVV-WIT-08 is situated in a dense area of the Milky Means, and researchers have thought-about if some unknown darkish object might presumably have drifted in entrance of the star by probability. Simulations present that there must be an impossibly massive variety of darkish our bodies floating across the galaxy for that situation to be possible.
Astronomers on the staff based mostly within the UK have discovered two more bizarre big stars along with VVV-WIT-08. The findings recommend this may very well be a brand new class of “blinking big” stars requiring investigation by astronomers. VVV-WIT-08 was found by the VISTA telescope in Chile.
