What's that black spot on Jupiter? No one is really sure. During a pass of NASA's Juno over Jupiter, the robotic spacecraft imaged a usually dark cloud feature, nicknamed the Abyss. Surrounding cloud patterns show the Abyss to be at the center of a vortex. Since dark features on Jupiter's atmosphere tend to run deeper than lighter features, the Abyss may really be the deep hole that it appears -- but without more evidence that remains unclear. The Abyss is surrounded by a complex of clouds and other swirling storm systems, some of which are topped by light colored, high-altitude clouds. The featured image was captured in 2019 while Juno passed only about 15,000 kilometers above Jupiter's cloud tops. The next close pass of Juno near Jupiter will be in about three weeks.

Study shows how amateur astronomers can aid in Jupiter weather monitoring

Jupiter's striking appearance comes from its stormy atmosphere. Swirling clouds surround the gas giant, and their distribution reflects the planet's weather. Scientists have used professional observatories such as the Very Large Telescope in Chile (whose construction in the 1990s cost more than 330 million euro, or US$366 million) and spacecraft such as the Juno orbiter (part of a US$1.13 billion mission) to study Jupiter's meteorology, but they lack some ongoing monitoring abilities. Amateur astronomers have filled in part of this gap by monitoring visible clouds and wind.

Now, in a paper published in Earth and Space Science, Hill and colleagues show that the chemical tracers of Jupiter's weather can be observed using relatively inexpensive equipment, which may allow amateur astronomers to contribute even more to scientific knowledge of the planet's conditions.

Unlike Earth's water-based clouds, Jupiter's topmost clouds are thought to be primarily made of ammonia ice; the atmosphere's ammonia content is indicative of the planet's weather. Ammonia absorbs red light at a wavelength of 647 nanometers. Methane, whose abundance is both fixed and well known to scientists, absorbs orange light at a wavelength of 619 nanometers.

Using a commercially available telescope priced at around US$4,000, the researchers took pictures of Jupiter and looked for spots where there was increased absorption at 647 relative to 619 nanometers, indicating increased ammonia abundance at those locations. They could then calculate the abundance of ammonia using the ratio of these absorptions and the known, unchanging abundance of methane.

This study showed changes in ammonia distribution over timescales ranging from weeks to years, but scientists need more data to understand what these changes mean. The authors say they hope amateur astronomers can use this method to help collect and share more data and that this increased workforce can allow for weekly or even daily monitoring of Jovian weather.

A beautiful view of polar Jupiter

Júpiter Polar Haze en color falso Publicado 1 de febrero de 2017 Esta vista en falso color de la neblina polar de Júpiter fue creada por el científico ciudadano Gerald Eichstädt utilizando datos del instrumento JunoCam en la nave espacial Juno de la NASA. La imagen se tomó el 11 de diciembre de 2016 a las 2:30 p. m. PST (5:30 p. m. EST), cuando la nave espacial se encontraba a 459 000…

It's a latte bigger than Earth. ☕

This picture isn’t from your local coffee shop, it’s from our spacecraft Juno as it passed by Jupiter. Jupiter is well known for its Great Red Spot, but it’s also home to anticyclonic storms, known as white ovals. White oval’s can be storms the size of earth and can generate winds up to 335 miles per hour (539 kilometers per hour) and some storms can reach 60 miles (100 kilometers) tall.

Jupiter is strapped with “belts” of white and red, that wrap around the planet. Traveling both east and west, why these belts are distinct is something mystery to scientists, one possibility is that the ammonia gas in the atmosphere travels up and down in alignment with the planets jet streams.

Juno’s prime mission of measuring and studying Jupiter’s atmosphere and magnetic structure was completed in 2021, but it will continue to measure the planet’s unique structure until at least 2025. This image was color enhanced by citizen scientists Gerald Eichstädt and Sean Doran.

Juno Flyby of Ganymede and Jupiter Video Credit: Images: NASA, JPL-Caltech, SWRI, MSSS; Animation: Koji Kuramura, Gerald Eichstädt, Mike Stetson; Music: Vangelis

Explanation: What would it be like to fly over the largest moon in the Solar System? In June, the robotic Juno spacecraft flew past Jupiter's huge moon Ganymede and took images that have been digitally constructed into a detailed flyby. As the featured video begins, Juno swoops over the two-toned surface of the 2,000-km wide moon, revealing an icy alien landscape filled with grooves and craters. The grooves are likely caused by shifting surface plates, while the craters are caused by violent impacts. Continuing on in its orbit, Juno then performed its 34th close pass over Jupiter's clouds. The digitally-constructed video shows numerous swirling clouds in the north, colorful planet-circling zones and bands across the middle -- featuring several white-oval clouds from the String of Pearls, and finally more swirling clouds in the south. Next September, Juno is scheduled to make a close pass over another of Jupiter's large moons: Europa.
