With China's advancing deep space exploration capabilities and critical progress in space-based nuclear power technology, the nation is basically ready to conduct orbital and close-in missions to ice ...

Launched in 1977, NASA’s twin Voyager spacecraft, Voyager 1 and Voyager 2, embarked on a historic journey to explore the ...

Voyager 2 flying by Uranus and Neptune is t he only time humanity has seen these worlds up close.

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, detect ...

Webb's depiction of Neptune's auroral activity is stacked atop Hubble's image of Neptune (left), which came long after Voyager 2's initial image from 1989.

Voyager 2 also took Neptune's upper atmosphere temperature. Webb scientists were surprised to learn that the planet has cooled over the past 34 years by hundreds of degrees.

This is because Neptune’s magnetic field has an odd orientation, which Voyager 2 revealed is tilted by 47 degrees relative to the planet’s axis of rotation.

Researchers believe Neptune’s unusual auroras are caused by the planet’s oddly tilted magnetic field, first discovered by NASA’s Voyager 2 in 1989.

More than three decades after Voyager 2's pass, scientists have seen Neptune's auroras again with the powerful Webb telescope, producing “the first robust detection," co-author Heidi Hammel of ...

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 ...
