Jupiter : the largest of the planets and fifth in order from the sun — Webster
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined. Jupiter is a gas giant, along with Saturn, with the other two giant planets, Uranus and Neptune, being ice giants. Jupiter was known to astronomers of ancient times. The Romans named it after their god Jupiter.
Jupiter is primarily composed of hydrogen with a quarter of its mass being helium, though helium comprises only about a tenth of the number of molecules. It may also have a rocky core of heavier elements, but like the other giant planets, Jupiter lacks a well-defined solid surface. Because of its rapid rotation, the planet’s shape is that of an oblate spheroid (it has a slight but noticeable bulge around the equator). The outer atmosphere is visibly segregated into several bands at different latitudes, resulting in turbulence and storms along their interacting boundaries. A prominent result is the Great Red Spot, a giant storm that is known to have existed since at least the 17th century when it was first seen by telescope. Surrounding Jupiter is a faint planetary ring system and a powerful magnetosphere. Jupiter has at least 67 moons, including the four large Galilean moons discovered by Galileo Galilei in 1610. Ganymede, the largest of these, has a diameter greater than that of the planet Mercury. — Wikipedia
In this animation the viewer is taken low over Jupiter’s north pole to illustrate the 3-D aspects of the region’s central cyclone and the eight cyclones that encircle it.
The movie utilizes imagery derived from data collected by the Jovian Infrared Auroral Mapper (JIRAM) instrument aboard NASA’s Juno mission during its fourth pass over the massive planet. Infrared cameras are used to sense the temperature of Jupiter’s atmosphere and provide insight into how the powerful cyclones at Jupiter’s poles work. In the animation, the yellow areas are warmer (or deeper into Jupiter’s atmosphere) and the dark areas are colder (or higher up in Jupiter’s atmosphere). In this picture the highest “brightness temperature” is around 260K (about -13°C) and the lowest around 190K (about -83°C). The “brightness temperature” is a measurement of the radiance, at 5 µm, traveling upward from the top of the atmosphere towards Juno, expressed in units of temperature.

- Space scientists reveal secret behind Jupiter's...on August 4, 2021 at 4:33 pm
New research has revealed the solution to Jupiter's 'energy crisis', which has puzzled astronomers for decades. Astronomers have created a detailed global map of the gas giant's upper atmosphere, confirming that Jupiter's powerful aurorae are responsible for delivering planet-wide heating.
- Hubble finds evidence of water vapor at Jupiter's...on July 26, 2021 at 5:21 pm
Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor.
- Spotted: An exoplanet with the potential to form...on July 22, 2021 at 3:29 pm
New high-resolution observations clearly show a moon-forming region around exoplanet PDS 70c. The observations have allowed astronomers to determine the ring-shaped region's size and mass for the first time.
- Scientists solve 40-year mystery over Jupiter's...on July 9, 2021 at 11:36 pm
Researchers combined close-up observations of Jupiter's environment by NASA's satellite Juno, which is currently orbiting the planet, with simultaneous X-ray measurements from the European Space Agency's XMM-Newton observatory (which is in Earth's own orbit). The X-rays are part of Jupiter's aurora -- bursts of visible and invisible light that occur when charged particles interact with the planet's atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but Jupiter's is […]
- Hubble watches how a giant planet growson April 29, 2021 at 5:53 pm
NASA's Hubble Space Telescope is giving astronomers a rare look at a Jupiter-sized, still-forming planet that is feeding off material surrounding a young star.

NASA's first spacecraft to explore the Trojan asteroids arrived Friday, July 30, at the agency's Kennedy Space Center (KSC) in Florida. It is now in a cleanroom at nearby Astrotech, ready to begin final preparations for its October launch.
- Discovery of very red bodies in the asteroid belt...on August 2, 2021 at 1:00 pm
Two asteroids (203 Pompeja and 269 Justitia) have been discovered with a redder spectrum than any other object in the asteroid belt between Mars and Jupiter. The discovery was led by HASEGAWA Sunao, Associate Senior Researcher at ISAS JAXA, with an international team of researchers from MIT, the University of Hawai'i, Seoul National University, Kyoto University and the Laboratoire d'Astrophysique de Marseille

Astronomers have captured the first-ever spin measurements of planets making up the HR 8799 star system.
- The second-coldest imaged exoplanet found to dateon July 29, 2021 at 11:21 am
Astronomers have discovered thousands of exoplanets—planets beyond our solar system—but few have been directly imaged, because they are extremely difficult to see with existing telescopes. A University of Hawaiʻi Institute for Astronomy (IfA) graduate student has beaten the odds and discovered a directly imaged exoplanet, and it's the closest one to Earth ever found, at a distance of only 35 light years.
