Gravitational assists are an emblematic example of why space travel is hard —it is exactly rocket science, after all. Gravity ...

Giovanni Cassini was born in Perinaldo, in what is now Italy, on June 8, 1625. Early work on Jupiter and Mars' rotational ...

Right after sunset, the largest and smallest planets are near neighbors in the sky. Jupiter, the brighter of the two, is a ...

Cassini captured Jupiter and moon Io on Dec. 1, 2000, revealing new details of the Great Red Spot and atmosphere. Thanks For Reading! Next: 7 jaw-dropping images of star clusters by NASA’s ...

Indeed, astronomers lost track of Cassini’s spot after 1713, and it wasn’t until 1831 that observations of a storm on Jupiter resurfaced. According to the new research, led by Agustín ...

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 ...

Astronomers in the 1600s, including Giovanni Cassini, also reported a similar spot in their observations of Jupiter that they dubbed the "Permanent Spot." This prompted scientists to question ...

I'm inclined to agree with Scott Bolton that what we're witnessing is the evolution of the spot. It could well be that the spot fluctuates over time and shrinks and grows again. Since the time the ...

Now, new research suggests that the Great Red Spot formed about 190 years ago, which means that Cassini observed something else on Jupiter in 1665. And despite being younger than previously ...
