The first look at Neptune's rings in detail since 1989 via the James Webb Space Telescope reveals sharper images and a glimpse at visual signatures that could be what drives the planet's winds and storms.
as it journeyed beyond the solar system and into interstellar space. That historic flyby gave humanity its first up-close view of the solar system's eighth planet.
The Webb observatory captured a previously known vortex at Neptune's southern pole and spotted a continuous band of clouds surrounding it, NASA officials said. There is also a bright area near the planet's northern pole that will require follow-up observations.Several of Neptune's moons are also visible, including Galatea, Naiad, Thalassa, Despina, Larissa and Proteus.
In one image, a bright blue feature that looks like a star is actually the moon Triton, which outshines Neptune because it is cloaked in a frozen layer of condensed nitrogen and reflects more sunlight than the planet and its atmosphere. Neptune was discovered in 1846 and is located 30 times farther from the sun than Earth. The planet's 164-year orbit takes it through some of the darkest and most remote regions of the outer solar system.
Neptune is considered an"ice giant" because of its internal chemical composition. Unlike Jupiter and Saturn, the gas giants of the outer solar system, Neptune is richer in elements heavier than hydrogen and helium, according to NASA.is a collaboration between NASA, the European Space Agency and the Canadian Space Agency. The tennis court-sized observatory is designed to study the early days after the Big Bang and help astronomers piece together how the modern universe came to be.
