This is the 100 year anniversary of humans having an idea of what the heck the sun and all the stars actually are. If you had asked a leading astronomer in 1925 what the sun was, they would say that it's basically the same as Earth, but very hot.
In Cecilia Payne's doctoral thesis she was the first to say, from spectral data, that the sun was overwhelmingly made of hydrogen and helium.
It was later described as "the most brilliant PhD thesis ever written in astronomy".
Relocated beavers improve River Glaven water quality
Two beavers who were moved from Scotland to Norfolk four years ago have improved the water quality where they are living, experts have said. Eeyore and Winnie have made an area of the River Glaven, near Holt, their home after the landowner gave permission for them to live there. Norfolk Rivers Trust said they could “possibly” now be released from their enclosure under licence after the government recently approved the reintroduction of the animals into the wild.
