The Aims of Psyche Mission to a Metal World: NASA Explains

The Psyche mission is a journey to an exclusive metal asteroid orbiting the Sun between Mars and Jupiter. NASA explains what makes the asteroid Psyche exclusive and unique is that it appears to be the exposed nickel-iron core of an early planet, one of the building blocks of our solar system. The Psyche mission is going to leave Earth in 2022. Although the original plan was supposed to launch in 2023, NASA has changed the timeline and is expected to start its mission in 2022. Observations from Earth hint that the 124-mile-wide (200 kilometers) world is 95 percent metal, just like the core of a rocky planet.

New Discoveries about Jupiter Internal Structure

NASA’s Juno probe has been discovering more about Jupiter Internal Structure than ever before. It is about its internal structure. The $1.1 billion spacecraft, which arrived in orbit around Jupiter in 2016, has been studying variations in the gas giant’s gravitational pull. The probe’s latest discoveries point out that Jupiter’s wind-sculpted bands extend down over 3,000km. That’s on a planet which is 140,000km wide. “This solves a long-time mystery,” said Juno scientist Tristan Guillot. According to him that was all really important for understanding atmospheric dynamics, not just on Jupiter but on other gaseous planets like Saturn, Uranus and Neptune and also the exoplanets they were at that moment discovering.

Jupiter’s Red Spot has been existing more than 188 years and now is disappearing

It is probebly that Jupiter’s big red spot will disappear according to NASA. The first time of the dimension of big red spot was measured about 1800s, which was four times bigger than the size of Earth. In July 2017 Juno has been cycling Jupiter for six years, flew close to the storm and measured it that it is 30 percent larger than Earth. Juno planetary scientist Glenn Orton said “”In truth, the Great Red Spot has been shrinking for a long time, now it’s something like 13 degrees wide in longitude and only 1.3 times the size of the Earth. Nothing lasts forever. The Great Red Spot will in a decade or two become the Great Red Circle. Maybe sometime after that the Great Red Memory.”

Top 10 Facts about Jupiter

Today, we have listed top 10 facts about Jupiter, that is worth knowing. Jupiter is the largest planet that we know of now. It’s similar to a star, but it never got big enough to start burning. It has big storms like the Great Red Spot, which has been going for hundreds of years. Jupiter also has rings, but they’re too faint to see very well. So there are many facts about Jupiter that is really fascinating, but we distinguished top 10 facts which is the most interesting.

The origin of water on Jupiter

French astrophysics established that a source practically all water in a stratosphere of Jupiter is the comet Shoemaker – Levy 9, fallen to a planet in 1994. Conclusions of researchers are based on supervision over a stratosphere of the gas giant, carried out by means of a space telescope Herschel. Data were obtained in the infrared range, with lengths of waves of 66.4 and 179.5 micrometers, where water has characteristic peaks of radiation. In work were used the spectrometers of PACS and HIFI established on a telescope. Made on the basis of data Herschel the card of distribution of water in a stratosphere of Jupiter was not uniform: in the southern hemisphere its concentration was much higher, than in the northern. According to astrophysicists, such heterogeneity unambiguously says, that its source is the comet Shoemaker- Levy 9, which in 1994 entered just into the southern hemisphere. Scientists specify that the water rising within of a planet would be distributed evenly. To other, more uniform distribution lead also other alternative scenarios, for example, water drift from the outside together with a space dust.

The Hot Spots in Atmosphere of Jupiter

Using the images from Cassini spacecraft, the scientists found that the hot spots of Jupiter’s atmosphere are created by a wave named Rossby. The hot spots are cloudless patches of Jupiter’s atmosphere. This is the first time that the scientists observed the hot spots, and this is the best way to appreciate the nature of features of hot spots. Also the scientists made movies from the observations taken by Cassini, during its last flyby Jupiter. The films zoom in (approximately 7 degrees) the hot spots between the dark parts and bright white parts of Jupiter.
About the hot spots the scientists much knew from Galileo spacecraft, which descended into a hot spot in 1995.

Scientists Discovered Salt Water On The Surface Of Europa

The scientists, who were observing the Jupter and its moons, discovered a salt water on the surface of Jupiter’s moon Europa. They suggests, that if someone can get to the moon through the all difficulties, and drink the water, the taste of water will be familiar. The Europa moon of Jupiter, overed with cracks and salt chemicals. The moon also has a gigantic ocean with frozen exterior. Because of this, the moon of Jupiter, is one of the most likely places to find life in our solar system outside of the Earth. In Hawaii the scientists used the telescope Keck, and mapped in the surface of Europa, an infrared wavelengths with 40 times greater resolutions, which they hadn’t obtained in the previous.

Explosion on Jupiter Captured Amateur Astronomers

American amateur astronomers Dan Peterson and George Hall  recorded a explosion on Jupiter caused by the fall of a large meteorite. Dan Peterson watched the gas giant with the twelve-inch amateur telescope. On Monday at 11:15 GMT, he discovered explosion on Jupiter, which took about 1.5-2 seconds. Scientists estimate that it caused the fall of a meteorite with a diameter of about 10 meters. The fall of large meteorites and explosion  on Jupiter – not very rare. Until 2010, they were recorded in 2009 and 1994.
