CAPE CANAVERAL, Fla. (AP) — Neptune and its rings haven’t looked this good in decades. NASA released new glamour shots of our solar system's outermost planet Wednesday taken by the James Webb Space Telescope.
This composite image provided by NASA on Wednesday, Sept. 21, 2022, shows three side-by-side images of Neptune. From left, a photo of Neptune taken by Voyager 2 in 1989, Hubble in 2021, and Webb in 2022. In visible light, Neptune appears blue due to small amounts of methane gas in its atmosphere. Webb’s Near-Infrared Camera instead observed Neptune at near-infrared wavelengths, where Neptune resembles a pearl with thin, concentric oval rings.
NASA’s Voyager 2 was the first spacecraft to see Neptune in all its gaseous glory, during a 1989 flyby. No other spacecraft have visited the icy, blue planet. So it’s been three decades since astronomers last saw these rings with such detail and clarity, said the Space Science Institute’s Heidi Hammel, a planetary astronomer working with Webb.Hammel tweeted that she wept when she saw the rings, yelling and making “my kids, my mom, even my cats look.
Webb is the world’s biggest, most powerful telescope, operating 1 million miles from Earth. It rocketed into space last December.
