It's a sobering statement that stars like the sun, more accurately all stars will die eventually—yes, even the sun. Don't panic, though, we still have a good few billion years to go so you will get to ...

An explosive event in the sky might soon captivate stargazers, as a research team led by the University of Turku predicts that the star system V Sagittae could soon light up the sky in a way that hasn ...
