Cassiopeia A by James Webb

This image is the latest from the James Web Space Telescope and it is Cassiopeia A, they are the remains of a supernova explosion that destroyed a star and everything within a radius of 40 light years, any planet that could harbor life would have been extinct by its radiation.

The super nova remnant of Cassiopeia A, as the bubble is technically called, is one of the best studied objects in the Milky Way, our galaxy, it has been studied across the entire spectrum of wavelengths, however, there are still hidden secrets inside the shattered remains of that star.

The recent look that the website has taken in near infrared has literally left researchers speechless, is what the NASA press release says, about the discoveries there are three things to highlight, on the one hand, something that we already knew but that we did not It ceases to surprise and the fact is that supernovae disperse enormous amounts of materials through space.

The James Webb has detected knots of gas composed of sulfur, oxygen, argon and neon, embedded in that gas is also a mixture of dust and molecules that will eventually transform into new stars and planetary systems in the future.

Even more strange is the loop of green light in the central cavity of Cassiopeia A that glows in the mid-infrared; researchers have called it the green monster and described this feature as difficult to understand.

The researchers were also, according to the press release in their statement, absolutely astonished, by an amazing feature in the lower right corner, it is a large striated mass that they have called baby Cassiopeia A because it looks like a little daughter of the main supernova, apparently It is a luminous echo where the light from the Star's former explosion has arrived and heats a distant dust cloud since in reality Baby Cassiopeia is located about 170 light years behind the supernova remnant.

These are just some of the things that are being discovered with the Casiopea space telescope and website. A supernova, a stellar apocalypse but also a seeding of materials that will allow new stars and planets, the sun, the earth and us to be harvested in the future. We ourselves exist thanks to that stardust that was launched into space when ancient stars died with a violent explosion, as Carl Sagan said, we are stardust and also children of the glow of a supernova.
