Temperature at our planet will increase greatly in the next few billion years.
Like any other planet Earth will be destroyed at a time. It will collide with another space object, whether it will be swallowed by a black hole or be bombarded by asteroids, Earth will have to know their end. In the event that none of the above phenomena will not occur, researchers at the University of Sussex, UK, argue that everything will end when the solar orb will conclude its work.
Experts say that every 1 billion years, the Sun's temperature increases by 10%. This phenomenon tends to evaporate water from the earth's surface and its accumulation in the atmosphere. Here, the water acts as greenhouse gases, accelerating the evaporation of water from the oceans.
Experts estimate that more than about 3.5 billion years the temperature on Earth would be 40% higher than the current one. For this reason, the water in the seas and oceans will completely disappear, glaciers will melt and the planet will have an appearance similar to that of Venus.
Sun working its core while burning the hydrogen atoms and helium atoms appear. And whilst the star is saturated with helium atoms, its dimensions are reduced and nuclear fusion reactions within it are accelerated.
Scientists say that in about 4 or 5 billion years, the hydrogen will disappear from the composition of the Sun, and it will begin to burn helium. Since then, the star becomes a red giant, it will lose its ability to sustain its orbit planets and cosmic objects are propelled into space or head to the sun. Experts argue that in any case, our planet will be destroyed.
After its reserves will be exhausted, the Sun will become unstable and begin to propel layers of its atmosphere into space, until that becomes a cold core surrounded by a planetary nebula. Scientists believe that, over time, will be sized white dwarf star ever smaller until they disappear completely.
