This astronomy picture looks like a cosmic battle to the death or a new TV series about aliens attacking Earth.
Nope! We actually shoot these four laser beams towards Eta Carinae, a nebula that has been exploding for nearly 200 years.
So, don’t worry! Earth is not doomed. Earth scientists are actively shooting lasers into the heart of an exploding star system… to know it better.
The purple star system pictured here is the Carina Nebula, sometimes called the Eta Carinae nebula.
It is one of the most luminous star systems in the Milky Way although being about 7,500 light-years from Earth. This is because it has been steadily exploding in a spectacular eruption of gas and dust for nearly 200 years.
Scientists fire these lasers from one of the ESO’s Very Large Telescope in Chile to simulate distant stars so they can get to know it better. More space news on ESO, Live Science, Strange Sounds and Steve Quayle.
