This colorful spot of things in space has a compelling history. This is a supernova remnant, the remnants remain after the explosive death of a star. We can see it thanks to NASA's Chandra X-ray Observatory, which can detect X-ray emissions that are beyond the reach of the human eye.

Quietly derives its name from the Danish astronomer Tycho Brache, who noticed its brightness at night sky as early as 1572. NASA released the view of the remnant on Friday and described it as "clumsy and lush."

The death of the star was spectacular. "This particular supernova was Type Ia, which appears when a white dwarf retrieves material from or fuses with a nearby companion star until a brutal explosion is triggered," a Chandra team said in a statement.

This 3D-printed supernova model resembles the X-ray view of Chandra on the remainder of Tycho's supernovae.

Astronomers are curious about Tycho's clumsiness and whether these forms were formed during the explosion or whether they occurred later. Scientists have launched a computer simulation that suggests the clumps occurred during the explosion.

"Until scientists are sure how, one possibility is that the explosion of a star has had multiple ignition points, with dynamite rods moving simultaneously in different places," an observatory team said. You can read more about this in a document published in The Astrophysical Journal.

Another team published an article on the creation of a Type Ia supernova model that can be 3D printed. You may never be able to touch a true supernova, but you can at least keep a model of one in your palm.
