Massive stars are the engine that drives the planetary systems we know. In ours, the luminosity emitted by solar radiation has the perfect amount for the development of life as we know it. However, at some point it will increase and conditions will change completely.
A scientific study carried out by different astronomy organizations and space agencies, reflected in the portal Xatakafind that the Sol will increase its radiation 2,300 times.
What will happen to Earth then? Surely we will no longer be around to witness this fact. Either because we move to another world (which would be the perfect situation) or because we will simply become extinct, humans will no longer be on the planet to experience this process.
This moment will mean an important change in the life of the Sun. It will be the first step towards its end as a massive star; the one where it becomes a red giant.
Solar radiation on the end of the massive star
Previous estimates indicate that the Sun has been around for 4.6 billion years. It is practically the same time as the Earth and the rest of the planets that orbit the star. According to the study outlined in Xataka, the king star has regarding 7,000 million years ahead of it.
But in half this time is that the planet’s biosphere will be affected by solar radiation. The illumination of the Sun increases as time passes. It is, inevitably, a natural process. It can’t be stopped.
Fortunately, this happens slowly and slowly. However, when the luminosity increases just 1.4 times what it is today, the oceans will evaporate. At this time we will no longer be here to tell regarding it; at least not from the inside. This event, according to studies, will occur within 3,500 million years.
About the end of the star’s life is that the solar radiation will increase regarding 2,300 times. At that time the star will continue to consume hydrogen and the fusion of the nuclei will begin. There the luminosity will be 40 times greater than the current one and there will be no life form in this system, because there will be a gravitational collapse.
