I was looking forward to writing a tribute to clear summer skies and great summer stargazing in the Pacific Northwest.

What do the clouds on Jupiter, dust storms on Mars and rainstorms on Titan all have in common? They look like they belong on ...

Another eyebrow-raising Jupiter drawing was created on Nov. 1, 1880, by French astronomical artist Étienne Léopold Trouvelot, recording five large black spots on the planet's North Temperate ...

Just a few years later, in February 2023, Jupiter took the lead with 12 new moons, beating Saturn’s 83 moons at the time. Only a short time later, still in 2023, the same astronomers who ...

Scientists have long thought that our solar system’s ocean worlds, such as Jupiter’s moon Europa and Saturn’s moon Enceladus, may harbor extraterrestrial life in the form of microbes.

From 2019 to 2023, Jupiter and Saturn went back and forth in a race to have the most moons. In 2019, Saturn took the lead with 20 new moons, reaching a total of 82, surpassing Jupiter’s 79.

While the moons of Jupiter don’t prove this idea is correct, they were evidence that the Aristotelian view adopted by the church – that everything in the sky revolves around Earth – was wrong.

A new study suggests that Jupiter ’s Great Red Spot, which has been visible for at least 190 years, is not the same one that astronomer Giovanni Domenico Cassini observed in 1665. Instead, the current ...

But “when Cassini pointed it instruments towards the night side of Jupiter, it saw exactly nothing,” says dark matter physicist Carlos Blanco of Princeton University, the study’s co-author.
