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.

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 ...

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.
