Re: Betelgeuse to go Supernova in Days or Decades?

Correct, HST’s incredible magnification abilities only work on light that’s arriving at the moment of capture, though it does allow us to see distortions and other anomalies affected by gravitational lensing. Didn't think of it that way. Makes sense. Sometimes, this stuff is hard to conceptualize, ...

Aircraft have generally been pressurized over the decades by excess bleed air drawn from the engine's compressor.
