Supernova Shards download the new version

The green indicated a glow at a specific wavelength, one no one expected and couldn’t explain. However, to make its output visible to our eyes, each part of the spectrum it is observing is assigned a color. Shards found in the places of exploding stars will play an essential role in the mythology and economy of our world, but more on that another time. The area in question is not really green, since JWST operates at longer wavelengths than we can see. Indeed, the remnant is so scientifically important a telescope was launched whose sole purpose was to study its X-rays, capturing all it could in a 15-minute flight.įor all its radio and X-ray power, there are some features of Cassiopeia A that can only be revealed in the infrared, as JWST showed earlier this year when it discovered a feature promptly named the Green Monster.

Following the invention of radio astronomy, they learned the remnant produces the loudest radio sounds, from our perspective, outside the Solar System above 1 GHz.

Astronomers may have a bone to pick with their negligent predecessors, but they’ve been making up for it since the discovery of the beautiful expanding shell of gas known as Cassiopeia A.
