Scientists Investigate Source of Fog in Pluto


As part of the New Horizon project, NASA looked closely at the dwarf planet Pluto in 2015 and realized that there was a layer of fog on the planet. Scientists are now investigating why this fog layer exists.

The data NASA obtained from Pluto in New Horizon in 2015 revealed an unexpected situation: Pluto is covered with a layer of fog. This fog cover on the dwarf planet can show that the planet may have sea or lakes as Saturn’s satellite, Titan.

“It is surprising that Pluto has a layer of fog,” said Bonnie Buratti, a scientist at NASA, at the 235th meeting of the American Astronomical Society on January 8. We were talking about Pluto as a new Mars. But Pluto seems to be a new Titan. ”

Titan is Saturn’s largest satellite. The satellite looks like the Earth because of the lakes, seas and thick atmosphere on it. However, the lakes and seas in Titan are composed of methane and ethane, not water. The lakes and seas in Titan ensure that the satellite has a cloud of fog.

Astronomers think that a phenomenon similar to that found in Titan can now be in Pluto. Buratti explained in his statement that the basis of his work was to establish the connection between the fog and the surface of the dwarf planet.

Scientists first want to find out what substances the fog in Pluto consists of. To this end, Buratti and his team are comparing the data from Titan and Neptune’s icy satellite Triton to the data from Pluto. Comparing the data can reveal which substances the fog in Pluto consists of.

The model obtained by comparing the data has already provided some information about the structure of the fog in Pluto. The reddish hue of the light signature of the fog in Pluto indicates the presence of organic matter in the fog.

Bonnie Buratti, who is working on the fog layer in Pluto, thinks that the limits of the research can be very big. It is thought that the fog layer in Pluto may be in other places beyond our Solar system. “Something similar can happen on the outer planets as the fog layer is observed in at least two celestial bodies in our Solar system,” Buratti said.
