Did you know about this unusual star?

It is 1300 times bigger than our sun and the largest yellow star known.  There is also a scientific mystery that has been solved four decades later.  Apparently there were some unusual light coming from a star of this yellow hypergiant which was totally unexpected.:

HR 5171A, also known as HD 119796A or V766 Centauri A, is a yellow hypergiant located in the constellation Centaurus, approximately 12,000 light-years away.

HR 5171A’s enigmatic blue light was accidentally observed in the 1970s by Leiden Observatory astronomer Dr Arnout van Genderen, but without providing a good explanation for it.

There is also another star making a lot of headlines lately in that it has an unexplainable “dyson sphere” around it.  Hopefully that won’t take 40 years to solve.

Let’s find out what caused this blue light and check out HR 5171A in a video on page 2
