Exquisite NASA Webb Telescope Image Reveals Neptune's Delicate Rings [via Nina Reznick}

 


Neptune is seen with its rings, a rare sight.

NASA, ESA, CSA and STScI

When we imagine a world embraced by cosmic haloes, we typically envision Saturn. Honestly, one might argue Saturn based its entire personality on those dazzling rings, and rightfully so. They're solid. Visible. Luxurious even. 

But if you didn't already know, it is my honor to tell you Neptune has rings too. 

They're just much daintier and therefore superhard to see without superpowered telescopes. The planet itself, in fact, lies 30 times farther from the sun than Earth does and appears to standard stargazing instruments as nothing more than a weak speck of light. 

Despite our inability to admire Neptune's fragile hoops from here, scientists caught a wonderful glimpse of them girding the azure realm in 1989 thanks to NASA's traveling probe Voyager -- and on Wednesday, the agency's equally exceptional James Webb Space Telescope presented us with round two. 

"It has been three decades since we last saw these faint, dusty rings, and this is the first time we've seen them in the infrared," Heidi Hammel, Neptune system expert and interdisciplinary scientist for the JWST, said in a statement. "Webb's extremely stable and precise image quality permits these very faint rings to be detected so close to Neptune."

And as if that weren't enough, this new image exhibits Neptune, surely emanating a soft lavender glow under the JWST's Near-Infrared lens, against a backdrop of galaxies deftly picked up by the same piece of next-gen space tech. It's unambiguous proof that the JWST is far too sensitive to capture what we might consider "blank space." This machine is powerful enough to serendipitously open a box of treasure every single time it gazes into the void.
