Jupiter’s iconic Great Red Spot is a massive storm that has swirled within the atmosphere of the largest planet in the solar system for years. But astronomers have debated just how old the vortex ...

The troubled Cassini probe will resume making scientific observations of Jupiter before flying by the giant planet to conduct joint studies with another spacecraft, NASA said Thursday.

In 1665, astronomer Giovanni Domenico Cassini observed a massive storm raging on Jupiter. It became known as the Great Red Spot, a swirling oval of clouds that’s almost twice as wide as Earth.

Jupiter's iconic Great Red Spot has persisted for at least 190 years and is likely a different spot from the one observed by the astronomer Giovanni Domenico Cassini in 1665, a new study reports.

Jupiter’s Great Red Spot—a rotating storm that is so large it could swallow Earth—isn’t what it used to be.. Research has revealed that the crimson-hued spot visible today is, on average ...

In the 1660s, Italian astronomer Gian Domenico Cassini discovered something while looking at the planet Jupiter: a massive spot now known as the planet’s signature. Known as the Great Red Spot ...

The first known observation of Jupiter’s red storm has often been attributed to Giovanni Domenico Cassini in 1665. However, new research suggests that the massive storm observed by Cassini is ...

Recent probe missions, like Juno and Cassini, have orbited Jupiter and Saturn, respectively. The information these probes sent back has changed that view. On September 15, ...

Jupiter’s striking Great Red Spot has puzzled astronomers for years. Now, they think they know just how old it is and how the cyclone formed in Jupiter’s atmosphere.

Astronomer Giovanni Domenico Cassini first observed what he called the “Permanent Spot” on Jupiter in 1665. New research suggests that the Great Red Spot formed about 190 years ago, which ...
