Why does Pluto have a heart of ice? Knowledge has the answer – 26/6/2022

Scientists have already noticed that Pluto has a heart-shaped region made up of ice. But how did this happen?

According to research by the French scientists Tanguy Bertrand and Fran├žois Forget, the existence of this glacier is the result of a combination of local surface features and atmospheric processes.

In the study, published in Nature in 2016, researchers detailed the structure of giant ice made up of frozen nitrogen mixed with carbon monoxide and methane.

It covers an area four kilometers deep and a thousand kilometers wide in the Sputnik Plain of Pluto.

To understand the origins of this glacier, the two scientists conducted numerical simulations of the evolution of the chemical components of glacial deposits in dwarf planet for 50,000 Earth years. They found that the terrain affected the formation of the glacier, intensifying the cooling of the ice.

Weather cycles also showed seasonal frosts that match data collected by NASA’s New Horizons mission and observations of polar flares seen since 1985.

Scientists’ simulations indicated that these seasonal frosts are expected to disappear within the next decade. The study authors say that future observations may provide new opportunities to test their models.

Ice “volcanoes”

Another study published in Nature Communications in March of this year revealed that there is even more evidence for this Glacial “volcanoes” become active Until recently on the planet Pluto.

Instead of spewing lava, they’re spewing a thick, muddy mixture of water and ice, “or perhaps a solid liquid like a glacier” from Earth, a planetary scientist at the South East Research Institute in Colorado, Kelsey Singer, told AFP.

The search was made possible by analyzing data and images generated by the New Horizons probe, the first spacecraft that explored Pluto in 2015.

Pluto was once a planet

Pluto was discovered in 1930 and has been highlighted for years as the ninth planet in the solar system.

However, in 2006, astronomers from the International Astronomical Union I decided to take her out of this category.

In general, a planet is considered as such when it is a celestial body, without its own light, and orbits a star.

In the case of Pluto, it does not meet the requirements, and its orbit with respect to the Sun is affected by the orbit of Neptune. Therefore, it is not parallel to the other planets in the solar system. That is, it depends on other celestial bodies.

The change was controversial. In 2019, NASA claimed that Pluto It should be considered a planetwhich reignited the debate.

In 2021, a new group of scientists argued that its reduction was On the basis of backward ideas. To date, Pluto is still not classified as a planet.
