A winter freeze will destroy Pluto's atmosphere by the year 2030, according to a 28-year study of the dwarf planet.
An international collaboration of scientists from eight countries has been studying Pluto's atmosphere and its evolution since 1988.
Pluto completes a long orbit around the sun every 248 years. Its distance from the sun means the surface temperature gets very cold.

Researchers gathered information from ground-based telescopes and the New Horizons spacecraft fly-by of Pluto in 2015. From their data, scientists were able to predict that Pluto's atmosphere was going to frost-out and vanish by 2030.
If that happens, the author of the study says the dwarf planet may appear brighter in our sky because it will reflect more sunlight.
