Jupiter s Three Red Spots
23.05.2008

For about 300 years Jupiter's banded atmosphere has shown a remarkable feature to telescopic viewers, a large swirling storm system known as The Great Red Spot. In 2006, another red storm system appeared, actually seen to form as smaller whitish oval-shaped storms merged and then developed the curious reddish hue.

White Oval Clouds on Jupiter
8.08.1997

What are those white ovals all over Jupiter? Storms! Jupiter's clouds can swirl rapidly in raised high-pressure storm systems that circle the planet. The above pictured white ovals are located near the Great Red Spot, and have persisted on Jupiter since the 1930s. The Great Red Spot has persisted for at least 300 years.

A Hurricane Over the South Pole of Saturn
13.11.2006

What's happening at the south pole of Saturn? To find out, scientists sent the robot Cassini probe now orbiting Saturn directly over the lower spin axis of the ringed giant. Cassini found there a spectacular massive swirling storm system with a well developed eye-wall, similar to a hurricane here on Earth.

What will become of Jupiter's Great Red Spot? Gas giant Jupiter is the solar system's largest world with about 320 times the mass of planet Earth. Jupiter is home to one of the largest and longest lasting storm systems known, the Great Red Spot (GRS), visible to the left.

Night on a Spooky Planet

Cycle 25 solar maximum made 2025 a great year for aurora borealis (or aurora australis) on planet Earth. And the high level of solar activity should extend into 2026. So, while you're celebrating the arrival of the new year, check out this spectacular auroral display that erupted in starry night skies over Kirkjufell, Iceland.

Clouds Over Tharsis on Mars
17.03.1998

When and where do clouds form on Mars? The Mars Global Surveyor spacecraft currently orbiting Mars is finding out. Photographs released last week showed clouds forming above Tharsis, a huge bulge on Mars about 4000 kilometers across and 7 kilometers high containing several large volcanoes.

Dawn of the Leonids
22.12.1998

Many of the 1998 Leonid shower meteors were so bright they could be seen even during sunrise. The above photograph was taken near the dawn of November 16 close to Hong Kong, China. However, most meteors are fainter and are not associated with any particular meteor shower.
