Uranus, the seventh planet in the solar system, between Saturn and Neptune, has long been a long puzzle. But by analyzing the observations made by NASA’s Hubble Telescope for 20 years, a research team from Arizona University and other institutions I have presented new visions In the formation and dynamics of the planet’s atmosphere.
Information about Uranus is limited. What we know is that the planet is mainly consisting of ammonia water and snow, and its diameter is about 51,000 km, about four times the Earth, and its sequence is about 15 times larger from Earth. Uranus also has 13 episodes and 28 satellites.
In January 1986, NASA Fwigger 2 successfully completed what it was, so far, the only exploration of the planet, which runs Flyby as part of its mission to study the external planets of the solar system.
But thanks to this new research, we now know more about this ice giant. According to the research, which values the Hubble photos taken between 2002 and 2022, the main components of the Uranus atmosphere are hydrogen and helium, with a small amount of methane and very small amounts of water and ammonia. Uranus shows the pale blue color because methane absorbs the red component of the sun.
This image of Uranus, taken by the James Web Telescope for NASA, shows nine satellites 28 of the planet and its rings.
The research also shed light on the seasons of the planet.
Unlike all other planets in the solar system, the axis of the rotation in Uranus is almost parallel to the orbital plane. For this reason, Uranus is said to revolve in a “turn” position, as shown in the image below. It is supposed to be This may be due to a collision with an Earth’s size object in the past.
Uranus revolves around the sun. It can be seen that the axis of the rotation in Uranus is almost parallel to the tropical plane.
The tropical period of the planet is about 84 years, which means that, for a specific point on the surface, the period in which the sun rises (some of the spring, summer and some fall) lasts about 42 years, and the period in which the sun does not shine (some autumn and winter and some spring) for about 42 years. In this study, the research team spent 20 years in monitoring seasons.
