On Saturn was summer

Titan, Saturn's largest moon, has a change of seasons. When in 2004 it flew to the spacecraft "Cassini", on the surface it was summer - testified to clouds and precipitation in the southern hemisphere. According to the calculations of astronomers, the following summer on Titan must have come in 2017, but that, for unknown reasons, did not happen. Despite the signs of the onset of summer in 2014, the delay lasted for about two years - the unit saw rainfall just now.

The onset of summer, scientists have learned in the course of the study made by the machine, "Cassini" shots. On one of them, made in June 2016, the satellite was captured land area of ​​120 000 square kilometers. This site reflects the light, that is, on the surface there is a huge pool of remaining after the rain. It should be emphasized that on Titan are not "boring" earthly rain - precipitation composed of liquid methane. Scientists suggest that the pool is not done on a smooth surface, and irregularities.

Scientists have found that the summer on Titan nevertheless took place, but with some delay. At the moment, they are trying to understand the reason for the delay when changing season. When it becomes clear, the researchers introduce adjustments to the climate they created a model of the satellite.

We want our model forecasts consistent with our observations. Detection precipitation proved that the climate of the satellite corresponds to our theoretical model. Summer has come. Belatedly, but it is. We have to figure out what caused the delay.

The scientists want to find out the exact schedule of the changing seasons on Saturn's moon, as these data can help in the improvement of atmospheric models distant exoplanets. Titanium is also interesting to scientists because it is one of the space objects that are suitable for life.
