Jupiter and its asteroid belt played a crucial role in the distribution of the essential chemical components necessary for life
As Jupiter formed and grew to enormous size and its gravitational influence increased, the planet restricted the movement of phosphorus and nitrogen from the inner to the outer Solar System. This meant that when the second generation of planetesimals emerged, those in the inner Solar System had a higher phosphorus-to-nitrogen ratio than their counterparts further out.
Jupiter’s Moon Europa: Water, Ice, Salt, and Sulfur. Latest Research
Europa is one of the most interesting moons in the solar system, it is one of the Galilean moons of Jupiter, along with Io, Ganymede, and Callisto. Astronomer Galileo Galilei is credited with discovering these moons, some of the largest in the solar system. Europa is the smallest of the four, but one of the most interesting. Europa’s surface is covered in ice, but scientists believe that there is an ocean underneath. The icy surface also makes it one of the most reflective moons in the solar system.
How Juno Explores Jupiter and Its Moons
New data from the agency’s Jupiter orbiter shed light on the fierce winds and cyclones of the gas giant’s northern reaches, as well as volcanic activity on its fiery moon. NASA’s Juno mission has obtained new data by peering beneath Jupiter’s cloudy atmosphere and onto the surface of its fiery moon Io. The data not only helped develop a new model to better understand the fast-moving jet stream that sweeps across Jupiter’s cyclone-strewn north pole, but also revealed for the first time the temperature profile beneath Io’s surface, providing insight into the moon’s interior and volcanic activity.
What has been learned about Jupiter in recent years? Latest information and photos from probes
Jupiter is the largest planet in the Solar System and the fifth planet from the Sun. This gas giant has beautiful banded clouds, thin dust rings, the famous Great Red Spot, and dozens of moons. Jupiter is also the oldest planet in the Solar System, having formed 4.6 billion years ago. Its distance from the Sun is an average of 484 million miles (779 million km). Jupiter is 86,900 miles (139,900 km) wide, or 11 times wider than Earth. A year on Jupiter lasts 11.86 Earth years. Jupiter has the shortest day in the Solar System, lasting only 10 hours. Jupiter is the fourth brightest object in the Earth’s sky after the Sun, the Moon, and Venus. There are enough planets the size of Earth to fit inside Jupiter.
Jupiter’s Moon Io. Timeline of Exploration
Io, Jupiter’s fifth moon, is the most volcanically active body in the solar system. Io’s surface is dotted with hundreds of volcanoes, some of which spew sulfur plumes hundreds of kilometers into the air.
Jupiter Mission: Present and Distant Past
Since the first flyby of Jupiter in December 1973, when NASA’s Pioneer 10 spacecraft flew past the gas giant, Jupiter has been the subject of numerous flybys and close encounters by pioneering Earth probes. Pioneer 11 made its closest approach a year after Pioneer 10 in December 1974, and Voyager 1 and Voyager 2 flew past Jupiter in 1979.
A quick overview of all of Jupiter’s moons
Jupiter, the largest planet in our solar system, boasts 95 moons, making it the second most populated planet by moon count (Saturn has the most). A huge gas giant, Jupiter is orbited by numerous moons; the four largest of these are known as the Galilean moons, discovered by Galileo Galilei using a telescope in 1610. The four moons – Io, Europa, Ganymede, and Callisto – are arranged in order of their distance from Jupiter. These moons proved that not all celestial bodies orbit the Earth, an important discovery because astronomers had previously believed that the Earth was the center of the universe.
The Juno spacecraft has discovered salts, organic compounds and water vapor on the surface and in the atmosphere of Ganymede, Jupiter’s largest moon
NASA’s Juno spacecraft has discovered salts and organic compounds on the surface of Ganymede, Jupiter’s largest moon. The discovery was made during a June 2021 flyby, during which Juno studied Ganymede with its Jovian InfraRed Auroral Mapper (JIRAM) instrument, an instrument designed to study the chemistry and interactions in the atmospheres of Jupiter and its moons. Ganymede, one of these moons, is the largest moon in the solar system — at 5,268 kilometers (3,200 miles) wide, larger than the planet Mercury — and has a vast ocean beneath its icy crust.
Jupiter’s Great Red Spot: What is Known About It Today
The Great Red Spot is an anticyclone, a long-term area of high pressure on Jupiter that creates persistent storms. Located in Jupiter’s southern hemisphere, this storm is the largest in our solar system and appears as a giant red spot on Jupiter’s surface. It has been around for 150 years, and may have been around longer, according to NASA.
Jupiter May Have Helped Form Earth’s Moon
The so-called “great instability” event that wreaked havoc among the planets and sent the gas giants hurtling through space until they settled into their familiar orbits appears to have occurred between 60 and 100 million years after the birth of the solar system, according to a thorough scientific investigation that has linked the meteorite to an asteroid once ejected by these destructive planets.
Basic principles of the Europa Clipper spacecraft, which studies the astrobiological potential of habitable worlds
Europa Clipper is NASA’s first spacecraft designed to explore an ocean world beyond Earth. Its goal is to find out if the ice-covered moon Europa is habitable. With its antennas and solar panels fully deployed, Europa Clipper is the largest spacecraft ever designed by NASA for a planetary mission. Europa Clipper’s flyby of Mars prepares it for its second gravity assist, a close encounter with Earth in December 2026.
Martian Phobos and Deimos Hide the Secret of Their Origin
For years, researchers have puzzled over the origins of Phobos and its twin, Deimos. Some have suggested that the moons are former asteroids attracted by Mars’ gravity, as their chemical composition is similar to that of some rocks in the main asteroid belt between Mars and Jupiter. However, computer models simulating this capture process have failed to reproduce the pair’s nearly circular paths around Mars. Another hypothesis suggests that a giant impact, similar to the one that created our Moon, ejected the duo from the Red Planet; however, Phobos has a different chemical composition than Mars, making this scenario unlikely.
The Voyager 1 spacecraft outside the solar system stopped sending useful data back to Earth
The Voyager 1 space probe is the farthest man-made object in space. It was sent in 1977 with a golden record on board that contained various sounds of our home planet: greetings in different languages, dogs barking and the sounds of two people kissing, to name just a few examples. The idea behind this recording was that Voyager 1 might one day become an emissary of alien life—a sonic time capsule of the creatures of Earth. Since its launch, it has also managed to complete missions to Jupiter and Saturn. In 2012, he crossed interstellar space.
Europa, a moon of Jupiter, generates enough oxygen to breathe for a million people during the day
NASA’s Juno mission measures the amount of oxygen on Europa. Jupiter’s ice-covered moon generates 1,000 tons of oxygen every 24 hours—enough to keep a million people breathing for a day. But the rate of oxygen production on Jupiter’s moon Europa is significantly slower than most previous studies. The results, published March 4 in the journal Nature Astronomy, were obtained by measuring hydrogen evolution from the surface of Jupiter’s icy moon using data collected by the Jovian Auroral Distributions Experiment (JADE) instrument.
Roscosmos: nuclear tug “Zeus” will go to explore the natural satellites of Jupiter
Today, the satellites of Jupiter – Io, Europa, Ganymede and Callisto – attract the closest attention of scientists around the world and are even considered as objects for colonization in the distant future. It has been established that some of them have oceans covered with ice, from under which steam sometimes escapes, and some tectonic activity is observed, which indicates a hot core of the celestial body. Heat and water are necessary conditions for the existence of life. The presence of people on the nuclear tug during the research is not planned at this stage.
