#2I'm getting cross-domain errors on the images on this page. The main one of the ring has this URL https://img.purch.com/h/1400/aHR0cDovL3d3dy5zcGFjZS5jb20vaW1... and if you base64-decode the last part you get http://www.space.com/images/i/000/075/580/original/hubble-te...
Here's the first video https://videos-f.jwpsrv.com/content/conversions/xTYS7F8k/vid...

#4They're quite neat, but haven't we had pictures of these for quite a while? Is there something new about this one, or is it ("just") an article reminding people that cool stuff still exists?

Yep, and the article pretty much admits that in the second half. The featured picture itself is years old. Title is pure clickbait.

Yes, for example: https://en.wikipedia.org/wiki/Cosmic_Horseshoe

#7Does this mean time travel is possible ?

No, not at all. Why would you think that?

#9why none of these articles mention non-desarguian geometry?

Its not clickbait - the article says we know about less than 12 Einstein rings. So finding 1 occurence of something we've only seen 12 of seems significant.
