Just one very unhelpful hint today: The name of this is as strange as the look. Read on to find out what it is and see the cosmic blue highlights …
It's what astronomers sometimes call a zombie star. More precisely, it's an explosive remnant of a dead white dwarf star. So the star dies, gets real quiescent, then explodes as if out of nowhere and billows outward, pushing a shockwave in front.
The technical name is a Type Ia supernova. This one is called Tycho's supernova remnant, named for the astronomer who Danish astronomer Tycho Brahe, who in 1572 saw the bright light from its explosion. It was so bright it was visible in the day time with the naked eye — only Venus, among all planets and stars in our sky these days, gets that bright.
Tycho's supernova remnant, Tycho for short, was first seen from Earth in 1572 when, as an exploding star, it was so bright it was visible during the day.

Tycho, as it's often referred to, is within our Milky Way galaxy, about 13,000 light-years from Earth. Other pictures of Tycho's supernova show it in different colors (taken in different wavelengths of light), but they all reveal the same odd look of a bushy head of hair. Here's one more.
