Pluto emit X-rays and does not have a magnetic field

Platoon hides before us many mysteries, and yet for many astronomers is “only” a dwarf planet. Very interesting news come to us from scientists working on the Space Telescope Chandra, who recently took up the study of this object.

A dwarf planet in the outer regions of the Solar System.
The first detection of Pluto in X-rays has been made using Chandra in conjunction with observations from the New Horizon spacecraft as it approached and then flew by the dwarf planet in 2015. During four observations, Chandra detected low-energy X-rays from the small planet due to interactions between Pluto’s atmosphere and a wind of particles from the Sun. The main panel in this graphic is an optical image taken from New Horizons on its approach to Pluto, while the inset shows an image of Pluto in X-rays from Chandra (not to the same scale). This result offers new insight into the environment surrounding the largest and best-known object in the Solar System’s outermost regions.

It turns out that the Pluto emits x-rays. So far, researchers have believed that for him, it’s impossible. For the first time in the history of the observation of our solar system, Kuiper belt, I was able to discover the object that emits such radiation, and at the same time, does not have a magnetic field!

This information tells us a lot about the atmospheres of properties through this part of the solar system. Scientists so far that the gases surrounding the cosmic body so very distant from the Sun can react with charged particles of the solar wind, creating x-rays (as is the case on Earth), but only now have irrefutable proof.

Interestingly, astronomers from the John Hopkins University also found that Pluto emits strong radiation x, as it is surrounded by the meager atmosphere. As long as they do not know why this happens.
