A Quick Look at a Star Survives Close Call with a Black Hole
A Quick Look at a Star Survives Close Call with a Black Hole
Astronomers may have discovered a new kind of survival story: a star that had a brush with a giant black hole and lived to tell the tale through exclamations of X-rays. (2020-04-23)


DEM L50: Beautiful But Deadly

View/Listen
Narrator (April Hobart, CXC): It seems that there is a twist in nature: the more beautiful something is, the more deadly it also might be. For example, some of the most colorful animals, insects and flowers can also be among the most poisonous. Is that also true in space? This new space image shows a pink bubble of gas glowing against a shining field of stars. Well, this pretty cloud is another of nature's dangerous beauties - it's shooting out huge amounts of intense, deadly radiation! Fortunately, we humans are safe from it however.

The glowing cloud of gas and dust in this picture is called a 'Super-bubble'. They are found in areas where lots of massive stars have formed fairly recently. These baby stars blow out intense winds and massive stars 'live fast and die young'. They speed through their lives to explode as powerful supernovas. It's these destructive events that have carved-out the center of the cloud, leaving behind just a ring of gas and dust.

The chaos taking place inside these giant super-bubbles stretches far beyond the hollowed cloud in the form of potentially dangerous X-ray radiation. Scientists have discovered that this particular cloud gives off 20 times more of these intense rays than they expected! So, here's another example of something that's beautiful but might be deadly! Our advice is: always enjoy beautiful things from a safe distance!
