The idea behind this made me laugh.
Chose Maud because her deadpan expression just seemed to make this funnier to me.
Did consider Pinkie at first, but I felt Maud worked better.
Did some googling on the topic. 30 LY would be catostrophic. I’m surprised we’d be safe at a few hundred, but apparently we would be. At least from Supernova. Gamma Ray Bursts (GRB) are a whole different story…
The size of said supernova. The smaller, the less of a threat.
And 2)
The distance. A supernova 10-15 lightyears distant could well damage our atmosphere. Further out the Earth’s electromagnetic field (the same thing that stops the sun’s radiation cooking everything), would probably be enough to protect against such an event.
That said, we do have a candidate that could seriously harm Earth. It’s a binary star system that’s going to go at some point. The stars are likely to collide, which (so I’ve heard) will form a black hole. When these things come in to existence they fire intense beams from their poles known as a “Gamma Ray Burst”. And we’re looking straight down on top of said system. I’d have to look it up to find the name of the star system.

If a star went supernova 100 LY away, we’d know for all of a few seconds before we died, and the date line would turn into a death sentence that slowly sweeps the Earth.
Stars live billions or tens of billions of years, if not hundreds or more for dwarfs (the universe is not old enough to have the stellar remnant - ie, a no longer fusing - red dwarf). Your chances of ever being around to observe the death of a star near enough to see in your lifetime are literally in the ballpark of one in a million. It’s very newsworthy if/when it happens.
@Cirrus Light
But if a star 100 lightyears away went supernova 50 years ago, we won’t know for another 50 years because the light from that event hasn’t reached us yet.
@kircher
Not really :q every star you distinctly see is within 100 or so light years. And I don’t believe there are any neutron stars or white dwarfs in there…
IK Pegasi A and B, perhaps?

I think that depends on 2 things.

I’ve been watching a series recently on Youtube, so I know plenty about what’s out there now.
Found this fascinating. (This has been speeded up. The speech sounds weird).
