Contos do Além: Espaço

Space.com

E o tremer dos astros pelo Espaço,
mostra o Céu como uma árvore de frutos de luz,
que uma mão titânica brutalmente arrepelasse…

A composite X-ray (blue) and infrared (red and green) image of the supernova remnant W49B reveals a barrel-shaped nebula consisting of bright infrared rings around a glowing bar of intense X-radiation along the axis.
The X-rays in the bar are produced by 15 million degree Celsius gas that is rich in iron and nickel ions.
At the ends of the barrel, the X-ray emission flares out to make a hot cap.
A flattened cloud of hydrogen molecules detected in the infrared surrounds the X-ray cap.
These features indicate that jets of hot gas produced in the supernova have encountered a large, dense cloud of gas and dust.
