Hubble Snaps the Residue of a Supernova Blast Resembling a Ribbon
Hubble Space Telescope is nearing the end of its life. Though it may be old, it certainly is not done blowing our minds. No doubt, having eyes up above is a useful thing and NASA is already working on other telescopes to put up above.
A couple of days ago on August 28th, NASA released pics of an orange ribbon floating in the space. What you see in the image is the remnants of a dead star that went out in a supernova some 10,000 or 20,000 years ago.
The exploded star whose blast wave we see as a ribbon was once a part of the Cygnus constellation, also known as the Swan or the Northern Cross. The part of the wave we see is situated 2,400 light-years away according to NASA.
Star should have about 8 to 16 times the mass of our Sun in order to turn into a supernova. This star had a mass of about 20 Suns back in its day, thus it could turn into a supernova too. And as it probably exploded between 10 to 20 thousand years ago, this remnant wave has had time to stretch 60 light-years away from its center.
NASA details that "The shockwave marks the outer edge of the supernova remnant and continues to expand at around 220 miles per second (354 km per second). The interaction of the ejected material and the low-density interstellar material swept up by the shockwave forms the distinctive veil-like structure seen in this image."
To put it in a simpler way, the things released from the exploding star got mixed up with the space debris (mainly gas and dust that was just floating around) and combined forces to form this utterly breathtaking pretty space ribbon.
