James Webb Telescope Captures Neptune's Auroras for the First Time

NASA's James Webb Space Telescope has captured bright auroral activity on Neptune for the first time, marking a significant milestone in understanding the planet's atmosphere.
Neptune's auroras were found at mid-latitudes due to its tilted magnetic field, challenging existing knowledge of its magnetic behavior.
The Webb telescope's observations showed Neptune's atmosphere has cooled dramatically since 1989, explaining why auroras remained hidden.
Henrik Melin from Northumbria University noted he was 'shocked' by the clarity and detail of the auroral images captured.

Neptune’s Long-Hidden Auroras Are Captured for the First Time–While Revealing a New Mystery

NASA’s Webb Space Telescope was finally able to capture bright auroras on Neptune—the most distant planet in our solar system. “In the past, astronomers have seen tantalizing hints of auroral activity on Neptune, for example, in the flyby of NASA’s Voyager 2 in 1989,” said the space agency this week. “However, imaging and confirming the […] The post Neptune’s Long-Hidden Auroras Are Captured for the First Time–While Revealing a New Mystery appea…

Astronomers finally spotted auroras on Neptune

Despite being part of our own solar system, Neptune has long been a cosmic mystery. It’s the most distant planet from the Sun and also one of the least explored. Only one spacecraft—Voyager 2—has ever flown by it, and even our most powerful telescopes have struggled to reveal much about its dynamic, icy atmosphere. But now, after decades of failed attempts, scientists have finally detected auroras on Neptune—and the discovery is already reshapin…

Auroras are spotted on Neptune for the first time, and lead to a new mystery - West Hawaii Today

The vermilion, amethyst and jade ribbons of the northern and southern lights are some of Earth’s most distinctive features. But our planet doesn’t have a monopoly on auroras. Scientists have spied them throughout the solar system, weaving through the skies of Mars, Saturn, Jupiter and even on some of Jupiter’s fiery and icy moons.

Webb Telescope Captures Neptune’s Long-Hidden Auroras in Stunning Detail

Long-Sought Auroral Glow Finally Emerges Under Webb’s Powerful Gaze Neptune lies in the cold, dark reaches of the outer edges of our solar system, about 3 billion miles from the Sun, at the farthest edge of the planetary lineup. Only one spacecraft has ever flown by: NASA’s Voyager 2 in 1989. Since then, telescopes like [...]
