The two massive storms were thought to be one and the same, but new research suggests the Great Red Spot formed more recently. Reading time 2 minutes In 1665, astronomer Giovanni Domenico Cassini ...

We present phase curves of Jupiter from 0-140 degrees as measured in multiple optical bandpasses by Cassini/ISS during the Millennium flyby of Jupiter in late 2000 to early 2001. Phase curves are of ...

Jupiter’s Great Red Spot was first discovered in 1665 by astronomer Giovanni Domenico Cassini, and both scientists and the public have been awe-stricken by its beauty and the processes that created it ...

WASHINGTON — 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 ...
