Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2016 September 14 The North and South Jupiter Image Credit: NASA, JPL, Juno Mission Explanation: A wide, looping orbit brought Juno close to Jupiter on August 27. As the spacecraft swung around the giant planet's poles JunoCam acquired these premier direct polar views, a change from the usual nearly equatorial perspective of outbound spacecraft and the telescopes of planet Earth. The sunlit side of Jupiter's north polar region...

For about 300 years Jupiter's banded atmosphere has shown a remarkable feature to telescopic viewers, a large swirling storm system known as The Great Red Spot. In 2006, another red storm system appeared, actually seen to form as smaller whitish oval-shaped storms merged and then developed the curious reddish hue. Now, Jupiter has a third red spot ...

Maybe Galileo morphed:-) http://www.space.com/scienceastronomy/jupiter_dark_spot_031023.html

Explanation: What are those spots on Jupiter? Largest and furthest, just right of center, is the Great Red Spot -- a huge storm system that has been raging on Jupiter possibly since Giovanni Cassini's likely notation of it 355 years ago. It is not yet known why this Great Spot is red. The spot toward the lower left is one of Jupiter's largest moons: Europa. Images from Voyager in 1979 bolster the modern hypothesis that Europa has an underground ocean and is therefore a good place to look for extraterrestrial life. But what about the dark spot on the upper...

Explanation: In infrared, Jupiter lights up the night. Recently, astronomers at the Gemini North Observatory in Hawaii, USA, created some of the best infrared photos of Jupiter ever taken from Earth’s surface, pictured. Gemini was able to produce such a clear image using a technique called lucky imaging, by taking many images and combining only the clearest ones that, by chance, were taken when Earth's atmosphere was the most calm. Jupiter’s jack-o’-lantern-like appearance is caused by the planet’s different layers of clouds. Infrared light can pass through clouds better than visible light, allowing us to see deeper, hotter layers of...

THE American space agency is planning to send a spacecraft to a lump of metal in space worth quadrillions of dollars. The 200km-wide asteroid is currently orbiting the sun between Mars and Jupiter. It is made up of various precious metals such as iron, nickel and gold. Experts believe the iron alone in the rock would be worth $10,000 quadrillion – enough to cause the world’s economy, worth $73.7 trillion, to promptly collapse altogether.

As NASA reports in a new post, researchers recently discovered that Voyager 2 cruised through a blob of charged gas called a plasmoid as it passed the planet. The spacecraft’s journey through the plasmoid lasted only about a minute, but that was still long enough for scientists to spot the anomaly in the decades-old data. The scientists believe that gas loss may have already drained as much 55% of the planet’s atmosphere. Loss of atmosphere resulting in plasmoids has been observed around other planets in our solar system, including Saturn and Jupiter, though it’s thought that Uranus has leaked far...

NASA’s Juno mission captured this look at the southern hemisphere of Jupiter on Feb. 17, 2020, during the spacecraft’s most recent close approach to the giant planet. Not only is Jupiter the largest planet orbiting the Sun, it contains more than twice the amount of material of all other objects in the solar system combined — including all the planets, moons, asteroids and comets. In composition, Jupiter resembles a star, and scientists estimate that if it had been at least 80 times more massive at its formation, it could have become a type of star called a red dwarf rather...

Early Tuesday morning, the waning crescent moon will be visible with the four planets down and to the left. As the sky begins to brighten, Mercury will rise and both Saturn and Mars will begin to fade from view. Both the Moon and Jupiter will remain visible as it gets lighter. By Wednesday morning, the moon will be closest to Jupiter and Mars. Jupiter is currently the brightest morning planet and it will be easy to pick out. Mars will be much dimmer in comparison. The moon will continue to get thinner as the week goes on. On Thursday morning,...

The popular Jupiter Shield theory proposes that the planet acts like a giant space shield due to its huge mass causing it to suck in or deflect dangerous debris. However, this shield theory is slowly falling out of favor and one of the leading critics is space expert Kevin Grazier. [Kevin R. Grazier, Ph.D.] He's published several papers explaining why he thinks Jupiter is a "sniper rather than a shield". Recently, he's been aiming to prove how this 'sniper-like' process works. Grazier's extensive work could put the Jupiter Shield theory in jeopardy. He told Gizmodo: "Actually, I wouldn't say that...

When is the best time to see Venus and Jupiter? Look for these planets on November 24 about 45 minutes after sunset, when twilight has set in and the sky is dark enough for Venus and Jupiter to dominate. Sunset is at 4:33 p.m. in New York, and it’s at 4:45 p.m. in Los Angeles, but you should check the exact time of sunset for your location. Where can you see Venus and Jupiter? Look to the southwest to see this special celestial show. You’ll find the planets about 7° above the horizon, so it might be wise to get...

Lucy team members presented the completed mission design, showing that they have met all the technical challenges of the mission and were ready to start building the actual hardware. At Lockheed Martin in Colorado over the course of four days, an independent review board, comprised of reviewers from NASA and several external organizations, heard all about the mission design. The Trojan asteroids orbit the Sun at a distance of Jupiter. The mission is set to launch in October 2021; with boosts from Earth's gravity, the spacecraft is expected to complete a 12-year journey to seven different asteroids.

The universality of Saturn worship 6000 years ago. NASA image: Israelites appear to have been the first people to figure out that humans should not be worshiping dwarf stars (Jupiter, Saturn...). And if worshiping dwarf stars and former dwarf stars was a problem 6000 years ago, it is more of a problem now. Troy McLachlan's book describes the connection between ancient Satanic ritual, drug dealing, central banking, and modern Satanic ritual (Jeffrey Epstein and the Hildabeast). The Saturn Death Cult

NASA’s Juno orbiter has detected ‘wave trains’ — massive structures of moving air that appear like waves — in the atmosphere of Jupiter Wave trains are towering atmospheric structures that trail one after the other as they roam Jupiter.They were first detected by NASA’s Voyager missions during their flybys of the giant planet in 1979.“Juno’s imager called the JunoCam has counted more distinct wave trains than any other spacecraft mission since Voyager,” said Juno team member Dr. Glenn Orton, of NASA’s Jet Propulsion Laboratory.“The trains, which consist of as few as two waves and as many as several dozen, can...

Home/News/Stony meteorites reveal the timing of Jupiter’s migration 941 Stony meteorites reveal the timing of Jupiter’s migration The gas giant caused iron-vaporizing collisions in the asteroid belt 5 million years ago. By K.N. Smith | Published: Tuesday, December 13, 2016 JUPITER_proccessed_image An artist's rendering of Jupiter WikiMedia Commons/ Ukstillalive The youngest stony meteorites in the solar system may reveal when Jupiter migrated through the asteroid belt. These meteors contain grains of metal that can only be the remnant of high-velocity collisions driven by Jupiter’s gravitational influence. New evidence comes from a rare group of meteorites called CB chondrites. Formed around...

Radio, IR and optical observations show evolution of plumes and their impact on belts and zones Storm clouds rooted deep in Jupiter's atmosphere are affecting the planet's white zones and colorful belts, creating disturbances in their flow and even changing their color. Thanks to coordinated observations of the planet in January 2017 by six ground-based optical and radio telescopes and NASA's Hubble Space Telescope, a University of California, Berkeley, astronomer and her colleagues have been able to track the effects of these storms -- visible as bright plumes above the planet's ammonia ice clouds -- on the belts in which...

Scans from NASA’s Juno spacecraft have hinted that Jupiter’s core isn’t exactly what scientists once thought it was. The core isn’t as dense as researchers suspected, but determining why that is has proven to be a challenge. “This is puzzling,” Andrea Isella, co-author of a new study published in Nature, said in a statement. “It suggests that something happened that stirred up the core and that’s where the giant impact comes into play.”

An amateur astronomer in Texas captured a rare sight earlier this week when an apparent meteor slammed into Jupiter’s thick upper atmosphere. On Wednesday, amateur astronomer Ethan Chappel was on the lookout for Perseid meteors, reports ScienceAlert. But his telescope was trained on Jupiter with the camera running. Later, after feeding the data into a software program designed to detect impact flashes, Chappel was alerted to the event. Looking at the footage, Chappel saw a brief but discernible flash along the western portion of Jupiter’s Southern Equatorial Belt, or SEB. Later that day, Chappel announced his discovery in a tweet:...

The rings of Uranus are invisible to all but the largest telescopes—they weren't even discovered until 1977—but they're surprisingly bright in new heat images of the planet taken by two large telescopes in the high deserts of Chile. The thermal glow gives astronomers another window onto the rings, which have been seen only because they reflect a little light in the visible, or optical, range and in the near-infrared. The new images taken by the Atacama Large Millimeter/submillimeter Array (ALMA) and the Very Large Telescope (VLT) allowed the team for the first time to measure the temperature of the rings:...

One of the big questions in solar physics is why the Sun's activity follows a regular cycle of 11 years. Researchers from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), an independent German research institute, now present new findings, indicating that the tidal forces of Venus, Earth and Jupiter influence the solar magnetic field, thus governing the solar cycle.
