So beautiful, isn’t it?
In 1572, astronomer Tycho Brahe noticed a new, very bright star had appeared in the constellation Cassiopeia, and this is what we see of it today. In fact, it was not a new star, but the explosion of a star which had originally been too faint to see with the naked eye. And now, thanks to the wonders of technology, we get to use it as a desktop background. Yay science!
