When it comes to cool space pictures, supernovae get all the credit. After all, who doesn’t love a good star death? But new images from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile reveal a stunning star birth that gives those supernova snaps a run for their money. It looks just like a firework, and now I have that godforsaken song stuck in my head, because the internet has rotted my brain.

According to the European Southern Observatory (ESO), a team of astronomers, led by John Bally from the University of Colorado, came across this fantastic display while observing the star-forming region known as Orion Molecular Cloud 1 (OMC-1). It’s part of the same complex as that Orion Nebula, roughly 1,350 lightyears from Earth.

Within the cloud, the team found the most incredible mess of debris from an collision between two baby stars. These youngsters are aptly called protostars, since their cores are not yet hot to undergo nucleosynthesis, the process by which stars make heavier elements and release energy. About 500 years ago, gravity drew the two protostars until they hit each other, although the researchers are not sure how direct of an impact it was. Regardless, the collision was so powerful—giving off as much energy as our Sun does in 10 million years—it sent other protostars, gas and dust streaming through space at 93 miles (150 km) per second. The team’s findings were published on January 10th in the Astrophysical Journal.

You make a good point. I wonder, then, how many older stars were close enough to feel the effects Binkie The Clown Apr 2017 #6

And how many civilizations obliterated in an instant.

they were young stars, so it's doubtful they had many planets. Any planets they may have had were very likely to have been in early stages of formation/development, so any life forms would most likely be fairly primitive. But--we'll never know for sure. The universe can be a very violent place, and life is always a crapshoot.

and how many of those might have had civilizations.

(You'll have to pardon me. I'm a hopeless sci fi fan.)
