Magnetic vortices twisting down from Jupiter's ionosphere into its deep atmosphere cause giant, ultraviolet-absorbing polar ...

Jupiter is a stunning planet to observe. Whether it be visible light or any other wavelength. In a stunning new image ...

When that wind slams into Earth's ionosphere, or upper atmosphere, the aurora is born. In the Northern Hemisphere, the phenomenon is called the northern lights (aurora borealis), while in the ...

These dark ovals, visible only in ultraviolet light, are located beneath the auroral zones at the poles, similar to Earth’s ...

Astronomers at UC Berkeley have identified mysterious Earth-sized spots at Jupiter’s poles with rapid life cycles.

While Jupiter's Great Red Spot has been a constant feature of the planet for centuries, University of California, Berkeley, ...

The aurora, a celestial display of vibrant lights, occurs when solar wind particles collide with Earth's atmosphere.

Auroras can appear green, pink, dark red, blue, purple and even yellow! But why? The aurora, also known as the northern lights (aurora borealis) or southern lights (aurora australis), is a ...

The light in the aurora comes from atoms in the ionosphere that have been excited by collisions with electrons that were accelerated between 6000 km and 20000 km above Earth’s surface. Those electrons ...

STEVE is a mysterious purple-white arc near the aurora, typically seen after space disturbances called substorms. A new study reveals a rare STEVE event without a substorm, prompting questions about ...
