PLUTO'S ATMOSPHERE IS STARTING TO LOST!..
Scientists have found evidence that the density of Pluto's atmosphere is beginning to decrease. This confirms suspicions that the dwarf planet has been "losing" its atmosphere for the past few years.
Located 4.8 billion kilometers from Earth in the Kuiper Belt, the icy dwarf planet caught the attention of astronomers as it passed in front of a star in 2018.
Scientists from the Southwest Research Institute in the USA were able to examine the atmosphere of the celestial body in detail, thanks to the backlighting of the dwarf planet.
Using telescopes at multiple locations in both the United States and Mexico, the team observed Pluto's thin atmosphere, which is mostly nitrogen.
Explaining their findings at the 53rd meeting of the Planetary Sciences Unit of the American Astronomical Society on October 4, the team found that as the dwarf planet moves away from the Sun, the atmosphere lowers and freezes on the surface.
According to the findings, Pluto's atmosphere is supported by the vapor pressure created by the ice on the surface of the dwarf planet. Therefore, the warming of the ice on Pluto can significantly change the density of the atmosphere.
Due to its elliptical orbit, Pluto gets closer and further away from the Sun from time to time. For nearly 25 years, the dwarf planet has been getting less and less light as it moves further and further away from the Sun.
Moreover, recent observations provide evidence that as the dwarf planet cools, its atmosphere refreezes and "disappears" at the surface.
However, the dwarf planet's surface pressure and atmospheric density continued to increase until 2018, according to the findings. Scientists attribute this to a phenomenon they call "thermal inertia."
Leslie Young, who is part of the research team and studies the interactions between the Sun and icy objects, likens the process on Pluto to the way the Sun heats the sand on the beaches.
"The sun is at its strongest around noon, but the sand continues to absorb heat in the afternoon, so it's hottest in the afternoon," says Young.
The fact that Pluto's atmosphere still exists indicates that the nitrogen ice reserve at the surface is kept warm by the heat stored below the surface. But new data reveals that they are starting to cool down, too.
