As Above So Below
The Curious Case of the Mystery Laser from the Ant Nebula
There is a really powerful laser beam shooting out of the distant Ant Nebula some 8,000 light-years away.
Is this an attempt at intergalactic communication, or is some strange and unknown natural phenomenon afoot?
Probably the latter.
Although would we really be able to tell the two apart?
The anomalous laser from the Ant Nebula was discovered by the European Space Agency (ESA) at the Herschel space observatory, one of the largest infrared telescopes in space. Recent observations conducted by Herschel have revealed an intense laser emission coming straight from the core of the nebula, and scientists aren’t quite sure exactly what is producing the beam.
There are a few extremely rare phenomena which can generate lasers inside of nebulae. Curiously, astronomer Donald Menzel was the first to suggest that lasers could be produced by nebulae in space, and Menzel also happens to be the astronomer who discovered the Ant Nebula (its official name is Menzel 3). According to Menzel’s theories, certain types of radioactive gases can accrete in dense clouds close to stars, and these gases can amplify stars’ light enough to produce beams of laser light.
Dr Isabel Aleman, lead author of the new study of the Ant Nebula lasers, says the coincidence of discovering a laser coming from this particular nebula is astonishing:
While I’m sure there are rare examples in which lasers can be generated by clouds of radioactive gas, I just have to wonder: if this was an alien race’s attempt at communication, would we even know it?

The Ant Nebula gets its name from the fact that it consists of two lobes of gas which resemble the head and thorax of an ant.
