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.
