Curious layman Posted January 4, 2021 Share Posted January 4, 2021 Quote The narrow galaxy elegantly curving around its spherical companion in this image is a fantastic example of a truly strange and very rare phenomenon. This image, taken with the NASA/ESA Hubble Space Telescope, depicts GAL-CLUS-022058s, located in the southern hemisphere constellation of Fornax (the Furnace). GAL-CLUS-022058s is the largest and one of the most complete Einstein rings ever discovered in our universe. https://www.nasa.gov/image-feature/goddard/2020/hubble-sees-a-molten-ring 1 Link to comment Share on other sites More sharing options...

Are we getting photons that would normally not reach us bent in our direction so that we can see them so that we get a higher definition image as a result?

Quote When light passes through this gravitational field, it bends. This creates a magnifying effect called gravitational lensing, which allows us to see objects that wouldn't normally be visible, or visible in such strong detail. https://www.sciencealert.com/icarus-blue-giant-most-distant-star-ever-seen-hubble-9-billion-light-years#:~:text=When light passes through this gravitational field%2C it,dependent on exactly the right alignment of objects. 1 Link to comment Share on other sites More sharing options...
