From Earth to the Universe: Picture of the day


W49B

This supernova remnant started life as a very large, very bright star that shed much of its a outer layers over a million years or so - a mere moment in stellar terms - before collapsing in on itself and then exploding as a gamma-ray burst, momentarily burning with the light of ten billion Suns. Blue colours reveal gas rich in iron and nickel glowing in X-rays at temperatures of 15 million degrees, green and red shows the infrared glow of hot hydrogen gas.
