No ammonia, really?Astronomers reveal the mystery of the atmosphere of the King of Heaven and Neptune

The stinky "paste" hail on the king star may explain the atmospheric abnormalities on the planet (and Neptune)

Recently, the huge hail rich hail richly found on Jupiter- "paste" may explain why heaven and Neptune seem to have no ammonia in the atmosphere of Heaven and Neptune.

Over the years, scientists have been confused without ammonia in the atmosphere of Uranus and Neptune.

Ammonia is famous for its unpleasant smell and is common in the universe. Because the atmosphere of Uranus and Neptune is rich in other compounds, these compounds exist in the primitive clouds when the planet forms, and it is difficult for scientists to explain why ammonia does not exist in this behemoth.

However, the hail -rich hail that is recently found on Jupiter may explain this mystery. Spoiler warning: Perhaps it is not completely without ammonia -ammonia may exist in deeper planet atmosphere, and the current scientific instruments cannot be reached.

The key to solving the mystery may be the Juno of NASA, and is currently performing tasks on Jupiter's orbit.

"Juno's spacecraft shows that a large number of ammonia exists in Jupiter, but (in the atmosphere) is much deeper than expected." Trelistan Gino, a researcher at the French National Science Research Center (CNRS) Speaking.

A study published last year in the magazine of Nature found that during thunderstorms, ammonia -containing balls were high in Jupiter's atmosphere. This is because ammonia can melt ice into liquid water even at a very low temperature of the Hualhi (minus 90 degrees Celsius) below 162.

These pastes fall in the atmosphere, absorb more and more ammonia, and eventually reach the quality of 2.2 pounds (1 kg). The ammonia was transported to the depths of the atmosphere blocked by the clouds.

"What we learned on Jupiter can be applied to the mystery of solving Uranus and Neptune." Gino introduced the theory at the 2021 European Planet Science Conference (EPSC). The meeting was held from September 13 this year to September 24.

"According to the theory of thermal chemistry, this process will be more obvious in the King of Heaven and Neptune, and the area where the ball began is expanded to a deeper place." Gino added.

This means that, just like the Jupiter, the ammonia on Neptune and Uranus is only hidden in the depths of the atmosphere. Scientists can only use infrared and radio signals on the earth's astronomical telescope to measure the atmospheric components on these remote planets.

So far, these two planets have only been patronized by a spacecraft, a traveler No. 2 of NASA, and probably. This is probably at the end of the 1980s.

Jino believes that the "guise" in these distant planet's atmosphere provides motivation for this research task, so that everyone wants to fully understand what is happening.

"To fully understand this process, we also need precision tasks to measure the structure of the atmosphere and understand the hydrogen atmosphere." Gilo said, "Uranus and Neptune are giant planets such as Jupiter and Saturn and we discovered by us in the Milky Way system. We really need to understand them! "

Uranus is the seventh planet from the inside out of the solar system. Its volume ranks third in the solar system and ranks fourth in quality. Its English name Uranus comes from the god of ancient Greek mythology Uranos. He is the father of Klunos and the grandfather of Zeus. Compared with the five planets known in ancient times, the brightness of the King Star was also visible to the naked eye, but because of the more dim and slow winding speed, it was not identified as a planet by ancient observer.
