It's germaine for human chomping, chest bursting outer space aliens when they are rampaging through the corridors of your spaceship. I wonder if it holds true when your star goes supernova?
I know. Not quite the same thing. In the movie, there is lots of blood and gore. And, admittedly, lots of localized screaming. But outside of the USCSS Nostromo, in the vacuum of space, it was pretty quiet.
They should've taken Ripley's advice to "nuke it from orbit."
Maybe that is what happened in Messier object M61. It had a star go supernova on May 6th and no one heard a peep. No screaming.
Well, the Zwicky Transient Facility (ZTF) sky survey only detected the new supernova on May 6th. It actually happened a really, really long time ago. The light from the event is just now getting here.
Imagine that the astronomers at ZTF were just sitting there looking through their telescopes at M61 and then, all of a sudden, a star exploded into brightness. Right before their very eyes.
No screaming. Not even a simple "pop," let alone a more boisterous "KA-BOOM."
This is M61, as imaged by me this weekend. It was nicely placed high in my southwest sky, in the constellation Virgo.
|M61. No screaming. No KA-BOOM.|
Just for fun, I uploaded the image to Astrometry.net to run a plate solve and this is what it found.

So, where is the supernova? Which one? It turns out that M61 has had 8 supernova since people have been paying attention to it. The latest is named "SN 2020jfo" and I've annotated in this image.

Pretty cool. I always learn something when I visit your blog.ReplyDelete
Very cool! Reminds of the Zenon Girl of the 21st Century “Supernova Girl” song :)ReplyDelete
