But because masses bend spacetime as Einstein's Relativity says, the light from the distant spiral bends AROUND the blob and gets magnified, creating an Einstein Ring! The phenomenon is called gravitational lensing. It's amazing to see it in action!

I just LOVE THIS!!

Yep, it bends around the earth because of its atmosphere. I saw somewhere someone put it very nicely, something like al the sunrises and sunsets around the world at that moment.

Ugh, correction. What I meant is that red light is scattered away, which is why when light is bent, red wavelengths come toward us like during sunrise and sunset (thus it's red then, but blue otherwise). I explain Rayleigh scattering all the time so I promise this is a typo 🤦♀️

It bends light and scatters red wavelengths more efficiently. Also, totality can last over 2 hours on the moon. Imagine that.

Wonder how a total eclipse with beads and a diamond ring can be seen from the moon when Earth appears ~3 times bigger than the Sun from there? Well, it's for the same reason lunar eclipses look red, and, why solar eclipses from the moon look red: Earth's atmosphere!

That's actually what we call that part of the eclipse! The diamond ring 😀

Yeah absolutely!

Okay, you're not looking at Earth from your balcony here. You're looking at a photograph. So I'm comparing to a photograph, because I'm comparing apples to apples, not apples to cats.

All about the field of view in the image. The moon looks tiny on a phone camera until you zoom in.

And a private company cannot operate without profit. In any case, I'm not on social media to try to convince people that they must see things as I do, and I'm certainly not on here to argue. I'm happy to have my opinions and share a world with people who have different ones. Have a great day!

A private company requires a "profit incentive," otherwise it wouldn't be able to pay its employees. I operate with a more realistic worldview. No one said anything is "restricted" to the private sector, but the private sector did benefit space exploration, which is why NASA works with them.
