The future is becoming clearer
Scientists have observed thousands of stars in our galaxy to try to unravel the mystery of the Sun’s future. It will enter an expansion phase, but we did not know for how long. This phenomenon does not bode well for our planet, since it will be uninhabitable long before the Sun reaches its maximum temperature.
Life cycle
Stars, like all living things, have a life cycle. Luckily for us, they live a long time. In fact, a medium-sized star like the Sun provides energy for several billion years. Indeed, their longevity depends on their mass. The most massive ones die following a few hundred million years. Conversely, the smallest stars can live up to 50 billion years.
The end
This scenario is likely to displease you. However, it corresponds to reality. According to scientists, our star will become a red giant in five to seven billion years. In a billion years, the Earth will become an arid desert since the oceans will have evaporated. Life as we know it will be completely gone.
