Out in the distant universe, an enormous crescent nebula is in the midst of shedding its ‘shell’ to reveal a wondrous image.
Now, the European Space Agency’s (ESA) XMM-Newton telescope has captured an incredible image of the Crescent Nebula in the constellation of Cygnus about 5,000 light years away.
This young, massive star began its life around 25 times the size of our own sun, but is now shedding ‘shells’ of material to create this stunning image released by ESA.
The shell of material it is shedding in this photo was created as it expanded into a red giant approximately 200,000 years ago.
The enormous gas bubble appeared as more recent fast cosmic winds collided with the material, causing the gases in the bubble to heat up and emit x-rays, seen as blue in the above image.
The green hue in the photo was created by oxygen atoms, where the star’s wind is interacting with the surrounding interstellar medium.
Offering a reason as to why there appears to be different structures in the bubble, ESA said that it is likely due to density differences of the material.
Elsewhere in astronomy this week, we heard some fascinating news from researchers using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, the world’s largest radio telescope.
By analysing two massive galaxies, the University of Arizona team discovered that they were oozing with dark matter, and showed that galaxies form a lot quicker than we once thought.
