The decision comes as the Voyager spacecraft face diminishing power supplies due to the gradual decay of their radioactive plutonium.

Hints of auroras were first faintly detected in ultraviolet light during a flyby of the Voyager 2 spacecraft in 1989. Webb captured Neptune’s shimmering lights in infrared light, providing ...

Nearly 40 years ago, Voyager 2 became the first spacecraft to observe Uranus up-close. Using radio signals from the planet's auroras and magnetic field data collected by the spacecraft ...

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. However, imaging and confirming the auroras on Neptune ...

WASHINGTON (AP) — Neptune's glowing auroras are captured in the best detail yet by NASA's James Webb Space Telescope. Hints of auroras were first faintly detected in ultraviolet light during a flyby ...

NASA's James Webb Space Telescope has captured a detailed image of Neptune's auroras, making it the first observatory to do so. Though Voyager 2 was the first spacecraft to fly by Neptune ...

The planet’s elusive aurorae are much colder than expected, which is how they evaded detection for so long.

The team was also able to take a temperature reading of Neptune, something that hasn't been done since Voyager 2's flyby in August, 1989. "I was astonished [by the results]," Melin said.
