The Webb Telescope captures the divine colors of the star's death

About 340 years ago, long before the United States was a country, light crossed over. Space And time from the giant exploding star finally reached Earth.

Cassiopeia A, a brilliant kaleidoscope of swirling colors in this image, is the least known of all. Supernova remnant(Opens in a new tab) In the Milky Way. This makes it a unique space object for astronomers to study. Death of a star They happen.

“Cas A represents our best opportunity to probe the debris field of an exploding star and understand what kind of star it was and how that star exploded,” said Dani Milisavljevic of Purdue University in Indiana. In the statement(Opens in a new tab).

Milisavljevic and other scientists recently made new observations of Cassiopeia A, also known as Cass A. James Webb Space TelescopeThe first infrared observatory in orbit, managed NASA and European and Canadian space agencies. Some astronomers have gone so far as to call it Best Webb image(Opens in a new tab) Yet, it shows more details than ever before.

Since infrared light is invisible to the human eye, researchers translate the data into visible wavelengths of light, which sounds like playing the same melody but at a lower octave. The new image can be thought of as gas and dust from the ashes of the star’s death.

The Cas A remnant spans about 10 light-years and is located 11,000 light-years away in the constellation Cassiopeia. in the New photo(Opens in a new tab), appears as a bubble with fiery red and orange curtains due to the hot dust. Inside is a ring with hot pink threads and knots, material from the dead star. Scientists say it’s glowing because of a mixture of heavy elements like oxygen, argon and neon.

“A type of astral examination…”

A research team nicknamed the Green Loop in honor of the Red Sox’s Fenway Park in Boston found “the green monster” just off center. It’s full of extra tiny and surprising bubbles that you don’t fully understand. Scientists are still trying to tease out all the sources of emissions.

Astronomers say that supernovae like Cas A are factories for producing elements: they make carbon, for example, the same chemical from which humans and most life on Earth are based. Metals such as calcium in the bones and iron circulate in the interstellar space in the blood. This new generation has seeded the stars and planets.

“By understanding the process of exploding stars, we are reading our own origin story,” Milisavljevic said. “I’ll spend the rest of my career trying to understand what’s in this data set.”
