Finally someone that has something interesting to say. Been very disappointed with the coverage. They sat on this image for 2 weeks before releasing, and at the presidential show gave NO insight an anything.

[@AnalogDude_]

It's even more fascinating, there can be time difference between the different "copies", the path one copy takes can be longer than other path, That's how they predicted a supernova, well where a copy of it would appear.

[@Tabu11211]

You where right! Nice call!

[@ebrombaugh]

Someone needs to write some analysis software to create a 3D view based on the redshift and gravitational lensing. Turn this image into a volume that you can spin around and look at from any angle, annotated with the masses that cause the lensing.

[@nightghost87]

Easy 🤣

[@berndb542]

the travel time of the light between the two images is likely be different. I believe this fact had been used to predict supernova - they had several mirror images from the same supernova due to a gravitational lens- once observed on one image they predicted one they will see this repeated on the mirror image

[@wadewoehrmann2835]

Good find - and as the light took different paths to get here how be it slight one could see the same galaxy at different points in time! If you are correct there will be 4 snap shots all perhaps thousands of years apart. Hummmm

[@aerofart]

Fascinating stuff. Speaking of mirrors, Being an amateur astronomer who has done my share of astrophotography, I’ve always suspected that there might be a way to “look around the corner” if we could somehow decode the reflections that must be emanating from our galactic nebulae. I’m guessing the SNR would be terrible and the uneven surfaces of the nebulae would have to be compensated for to create a somewhat planar surface, but in theory it should be possible. One of these days . . . Mark my words.

[@soulrobotics]

Could it be a calibration problem on the sensors? I wish they take the picture again...

[@albyboy4278]

Excellent explanation, you have clarified my doubts. At first I couldn't understand why they are bent like that but then I understood by looking closely. I've seen some scientists on KZbin explaining that space has folded, not light that has passed through a gravitational lens. You just proved their ignorance is at a high level 😂

[@Chris_Grossman]

It is easy for me to understand the light bending, but the mirroring is not readily apparent. Perhaps you could come up with a diagram to explain the mirroring.

[@IMSAIGuy]

I can't explain it either.

[@JoseHernandez-md8tv]

Take a curved glass with round bended thick walls toward the bottom and hold it in distance above a candle light. You will get a similar effect and will akso have mirroring to the other side.

[@IMSAIGuy]

@@JoseHernandez-md8tv while that is true, I'm not sure it is a analogy to what is going on in space. Does it explain the Einstein cross?

[@IMSAIGuy]

also, it generates two images but are they mirrored left to right or just two copies both the same direction

[@JoseHernandez-md8tv]

@@IMSAIGuy I wonder what a glass sphere with bold and transparent walls and dark core would cause to a light sourcd bdhind it? Einsteins cross is something I can not imagin how it works. Interessting are all those effects for sure.

[@JoseHernandez-md8tv]

Notice the redish just a lttle below, that is mirrored too. Just side by side.

[@jbrown468]

That is very cool -- thank you!

[@richardl6751]

At 1:10 More like hundreds of MILLIONS of light-years away.

[@spencerjones7809]

Can we determine where the mass that distorted the galaxy is by following the mirror lines, is this useful for a similar purpose?

[@IMSAIGuy]

I'm sure the real astrophysics can do that and will

[@mr1enrollment]

Very cool topic, I bet some other smart Phd candidates are writing code to correct for the mirroring and rotational aspects,... Lot of buried data, not just fabulous images!

[@michellegiacalone1079]

No, it's a byproduct of gravitational lensing- we're seeing one galaxy twice.

[@IMSAIGuy]

yes, hubble has see that before, but I can't get an explanation of the optics. in addition to a lens there has to be a mirror/prism.

[@luomoalto]

@@IMSAIGuy Or are we seeing light that was emitted from the galaxy at different angles, then bent by different masses? But then why does it look like a mirror image? Hmmm…

[@IMSAIGuy]

@@luomoalto google 'Einstein cross' and 'Einstein ring'

[@octavianconstantintudora9804]

May be someone can apply Photoshop lenses image stretch correction of that galaxy

[@BjornV78]

0:12 Looks like the bottom of my wallet

[@OneZombieHorde]

This can probably be explained by the fresnel effect of the light bouncing off of matter seen as the cloud in the image. Thinking of it as like an echo, but also a reflection. A result of the reflectivity and of the composition of the universe. Everything has fresnel.

[@IMSAIGuy]

a Fresnel reflection is very weak. it needs to be a GRIN lens or prism effect that can preserve the light. I did optical design for 30 years.

[@guff9567]

Clearly photoshopped

[@IMSAIGuy]

hubble also saw this effect multiple times. this one is just really in focus
