Astronomers a...
Will that be the fate of our sun? Will it – at the end of its life – become briefly visible to alien astronomers on planets millions of light-yearsaway? These astronomers say no. They say their models predict that our sun – though forming a planetary nebula at the end of its life – will remain faint. Read more about this study from the University o...
