They don't affect Mars, they are an effect of Mars' atmosphere at sunset.
On Earth we have a lot of images of sun rays, light coming through clouds being visible in the air. But Mars only has a few cameras on it, so the chances of seeing sun rays is much less- it finally happened.
But it's not just about looks, it helps researchers better understand things such as Mars' atmospher or weather.

That doesn't really help -- if everything was extremely close to everything else, then just pick 'X' to be the geographic center of all of that -- the exact center of the uninflated balloon if you like. At the beginning, we may not have been precisely at X, but we were very very close to it.

(Also, I intended X to be where we are now, not where the mass that is currently the earth was at the point of the big bang. But, that was not at all clear, so I'm just going with 'X= point of the big bang.')

There is no X. Things didn't get ejected, everything was extremely close to everything else, and of a sudden they started to get far away from everything else. It's like the surface of a baloon, if you inflate it, everything is further apart, there is no "point of ejection" on the surface.

Im no expert, but Afaik it's pretty rare(especially as strong as this), but because of the scale of the observable universe it's pretty common. But by gathering spectra it's very easy to determine. https://webbtelescope.org/contents/media/images/2022/035/01G7HRMY93K0BCCBKCABAQH0V7?news=true
