Approximately 2,200 light-years from where you're sitting lie the Cheerio-shaped remains of a dying star — remnants that form a structure famously known as the Ring Nebula. And on Monday (Aug. 21), scientists announced the James Webb Space Telescope has struck gold once again, earning a rather beautiful new view on this iconic cosmic halo.
"When we first saw the images, we were stunned by the amount of detail in them. The bright ring that gives the nebula its name is composed of about 20,000 individual clumps of dense molecular hydrogen gas, each of them about as massive as the Earth," Roger Wesson of Cardiff University said in a statement.
