Can gravitational lensing be slight?

• by librastrahl

  I mean, there are obvious cases, but would it be of any interest if there were even the slightest lensing event in the image?

  Hi librastrahl and welcome to the Zoo

  Where do you see any lensing in this image ?

  There is a weaker effect called, funnily enough, "weak lensing" - it's studied using statistical approaches and it is a really interesting field of study.

  Here are some links with further information:
