We all heard about the name of URANUS.  It is the part of our solar system. In this magazine article I am writing about some information of Uranus and some interesting facts about it. On the other hand why these facts are presented in this planet, we are going to know about it in this article.

  Uranus is the seven planet from the Sun. Its name coming from the ancient The Greek God. It has two sets of rings around the equator. The planet, which has four times the diameter of earth, rotates on its side, making it different from all other planets in the solar system. Uranus orbits the Sun once every 84 years. In 1865 it was completed its First rotation and In 2033 it will be completed its 3^rd rotation on this orbit. Its atmosphere is similar to Jupiter and Saturn’s for Hydrogen and Helium. The difference between it’s minimum and maximum distance from the earth is 1.8 AU (Astronomical Unit). Voyger-2 { It is a space probe launched by NASA( National Aeronautics and Space Administration) on August 20,1977}.  According to the Voyger-2 records the lowest temperature in Uranus is 49kl (-224.2C, -371.5F).  Voyager-2 called it as the coolest planetary in the solar system. But we didn’t think about the actual reason of this cool weather. So I am telling you that. In this planet it contains Hydrogen and Helium. But it contains more things like water (H-O-H) Ammonia (N-3H), Methane(C-4H). For this elements It became the coolest planetary in this solar system,

   I want to tell you abut this planet more in this paragraph. In the new study researchers used Chandra Observations taken in Uranus in 2002.Only Voyger-2 flew in the Uranus but Astronomers rely on Hubble Telescope and Chandra which is much closer to earth and also give them the observation results. In new study the observations taken from Chandra in 2002 and also taken in 2017. They saw a clear detection of X-rays from the first observations, just analyzed recently and a possible flare of X-rays in those obtained 15 years later. The main graphic shows a Chandra X-ray image of Uranus from 2002 superimposed on an optical image from the Keck-I telescope obtained in a separate study in 2004. The latter shows the planet at approximately at the same orientation as it was during 2002 in Chandra observations.

 

 In this picture we can clearly saw that X-ray emits from the Uranus. But we didn’t know about the reason behind this. I am telling in this page.  From the new researching paper researchers clearly point some important reason and explain about this.  The first reason they mentioned that for mainly Sun. Astronomers have observed that both Jupiter and Saturn scatter X-ray light given off by Sun, similar how atmosphere scatters sun lights. But authors found some tantalizing hints while they are doing study on it. 

They said one possibility is that the rings of Uranus are producing X-rays themselves, which is the case for Saturn rings also. Uranus is surrounded by charged particles such as electrons and protons in it are near by space environment. If these energetic particles collide with the rings, they could cause the rings to glow in X-rays.

  Another possibility is that the x-rays are also coming from the Auroras on Uranus, a phenomenon that has previously been observed in this planet. On earth, we can see colorful light shows in the sky are called Auroras, which happen when high energy particles interact with the atmosphere. X-rays are emitted in Earth’s auroras, produced by energetic electrons after they travel down the planet’s magnetic lines to its poles and are slowed down by the atmosphere. This was some possibility of x-rays on Uranus but however scientists are less certain about what causes auroras on Uranus. Chandra’s observations may help to solve the mystery.

Uranus is an especially interesting target for X-ray observations because of these unusual orientations of its spin axis and its magnetic field. A paper describing these results appear in the most recent issue of the Journal of the Geographical Research.
