See Stars Sing! Video Of Stars With Sound Amazing!
Im not even going to try to explain this. It's just one of those internet things that is very cool. We live in an amazing age. Every generation says that, but those people had no idea the things we discover these days.
And when I say "we", I mean the people at nature.com. In the story "An observational correlation between stellar brightness variations and surface gravity" it gets pretty technical. Im not gonna lie.
"Surface gravity is a basic stellar property, but it is difficult to measure accurately, with typical uncertainties of 25 to 50 per cent if measured spectroscopically1, 2 and 90 to 150 per cent if measured photometrically3. Asteroseismology measures gravity with an uncertainty of about 2 per cent but is restricted to relatively small samples of bright stars, most of which are giants4, 5, 6. The availability of high-precision measurements of brightness variations for more than 150,000 stars7, 8 provides an opportunity to investigate whether the variations can be used to determine surface gravities."
Right. Watch this. WAY better.
Two words. F'ing cool.
You can go back to normal things now.
