It’s always day if you’re a star. Or night?
lugal@lemmy.ml 4 days ago
Yes, that’s the problem

I like the corona though.

Well of course, because it’s spinning too fast. So you don’t see the star shape, only the blurry circle!

Why star, if not star shaped?

A smart and wise person uses this opportunity to teach. A smug asshole uses this opportunity to scoff.

Goodness gracious, great balls of fire!

From e we hat angle would you look at the traditional star shape and see a circle?

I’ll take you for a ride. A ride on a meteorite.

Are we sure it’s not a blurry picture of a slice of chorizo?

Looks like it’s holding a bag baby. Awwww!

Not really a bad question. The diffraction spikes have been corrected for.
Thorry84@feddit.nl 4 days ago
Honest question: Do people think stars look like the star shape because of diffraction spikes in refractor telescopes? I thought the star shape pre-dated any refractor telescope. And I don’t know how many people would have seen refractor images back in the days to make it so culturally engrained?
The post-processing used in astronomical observations is a really interesting topic. I’m following the debate around the black hole images with great interest. I don’t know enough about the specifics to have an opinion, but it is very interesting and has overlap with some of the things I do for work.

I’ve always wondered this. For now I’ve settled on the hypothesis that all the first astronomers all had astigmatism.

People have indeed thought this before telescopes. You’ll most likely see diffraction patterns around bright lights because of eyelashes and other imperfections, probably different for each eye but the same for all lights (technically, wavelength also matters but not really on this scale).

They look star-shaped because of refraction on the atmosphere and in our eyes. Those telescopes just have way larger relative distortions because they do have larger distortions and can see smaller things.

there are a series of things that can make points of light look spiky: eye defects, eyelashes when squinting, smudgy glasses, etc…
