The Puppis A Supernova Remnant. The square shows the Bright Eastern Knot which is the target of the Micro-X rocket.
When we look at the sky during the night it is possible to appreciate stars of different colors and brightnesses. However, although we may think that stars will bright forever, the stars, as all the existence on the Earth and space, also have their life-cycle. There’s a type of stars called the supergiants that emit lots of luminosity. When a supergiant star collapse with itself in a way that they can produce an explosion, it produces what is known as supernova. A supernova is the process that occurs when a star’s life-cycle ends and explodes. In this process, the supernova explosion may produce a huge amount of energy similar to the one emitted by the Sun that is also a star.
