James Webb Telescope, NASA’s Divine Discovery
- LONDON (AP) — The James Webb Space Telescope has captured the most detailed images yet of Neptune's glowing auroras.
- Hints of auroras on Neptune were first faintly detected in ultraviolet light during a flyby by the Voyager 2 spacecraft in 1989.
- Auroras occur when energetic particles,frequently enough originating from the sun,become trapped in a planet's magnetic field and collide with the upper atmosphere.

LONDON (AP) — The James Webb Space Telescope has captured the most detailed images yet of Neptune’s glowing auroras.
Hints of auroras on Neptune were first faintly detected in ultraviolet light during a flyby by the Voyager 2 spacecraft in 1989. The Webb telescope captured Neptune’s shimmering lights in infrared light, providing direct evidence of their existence.
Auroras occur when energetic particles,frequently enough originating from the sun,become trapped in a planet’s magnetic field and collide with the upper atmosphere.
This collision releases energy, frequently enough in the form of light.
Astronomers have observed auroras on Jupiter, Saturn, and Uranus. However,capturing images and confirming auroras on Neptune proved challenging until now.This observation fills a gap in understanding auroral activity on the giant planets in our solar system.
According to a researcher from the University of Northumbria, imaging Neptune’s auroras was only possible with the infrared sensitivity of the Webb telescope.
it’s amazing not only to see Aurora, but the details and clarity of the signs really surprised me.
In June 2023, data was collected using an infrared spectrograph. Along with the images, astronomers obtained a spectrum to study Neptune’s atmosphere, specifically the ionosphere’s composition and temperature.

What are Auroras and How Do They Form?
Auroras, also known as the Northern Lights (Aurora Borealis) and Southern Lights (Aurora Australis) on Earth, are spectacular displays of light in the sky. They occur when energetic particles from the sun become trapped in a planet’s magnetic field and collide with the upper atmosphere. This collision releases energy, frequently enough in the form of beautiful, shimmering light.
Have Auroras Been Observed on Other Planets?
Yes, astronomers have observed auroras on several other planets in our solar system, including Jupiter, Saturn, and Uranus. However, capturing detailed images and confirming auroras on Neptune presented a significant challenge untill recently.
How was Neptune’s Auroras Captured?
The James Webb Space Telescope (JWST) captured the most detailed images yet of Neptune’s auroras. Researchers used the JWST’s infrared spectrograph to collect data.
Imaging Neptune’s auroras was only possible with the infrared sensitivity of the Webb telescope.
Was This The First Detection of Neptune’s Auroras?
No.Hints of auroras on Neptune were first faintly detected in ultraviolet light during a flyby by the Voyager 2 spacecraft in 1989. Though, the James Webb Space telescope provided direct evidence of their existence with its infrared observations, capturing them more clearly than ever before.
What Makes the JWST’s Observations of Neptune’s Auroras Significant?
The JWST’s observations are significant for several reasons:
Detail and Clarity: The images provide unprecedented detail of Neptune’s auroras.
infrared Light: The telescope’s ability to see in infrared light made these observations possible.
Understanding Auroral Activity: This observation helps fill a gap in our understanding of auroral activity on the giant planets in our solar system.
Spectrograph: To study Neptune’s atmosphere for composition and temperature.
when Was This Data Collected?
The data from the James Webb Space Telescope was collected in June 2023.
