Astronomers recently observed two objects in the solar system – Uranus and Neptune – in radio and infrared bands. It turned out that there is much less ammonia on both planets than it should be.
Observations by astronomers from the Lagrange Laboratory have shown that Uranus and Neptune have much less ammonia than other giant planets in the solar system. This substance, similar to methane, should be abundant on the planet. As you know, it is formed when an object is formed from a protoplanetary disk.
To explain the absence of ammonia on the surfaces of Neptune and Uranus, scientists studied the ammonia content on another giant planet – Jupiter. The data of the comic probe “Juno” showed that this chemical compound is located not only on the surface of the planet, but also deep under its “surface”. Periodically, hailstones are formed on Jupiter from a water-ammonia mixture, which can reach up to a kilogram or more in weight. When they fall, they carry matter far into the atmosphere. Scientists concluded that similar processes also occur on Uranus and Neptune.
The reason for the abnormal decrease in ammonia was explained by the fact that the chemical compound simply disappeared into the atmosphere. However, to confirm this theory, it is necessary to send an orbiting probe to Uranus and Neptune.
