Scientists acknowledge that the universe is full of surprises. One of them is that as it grows and develops, it becomes more and more inclined to have places that support life. During the era of the first microbes on Earth, the Universe was much less welcoming than it is today.
Conditions that give rise to life are previously rare. But experts have revealed that Space nowadays is a lot more life-friendly than it used to be. They predict it’s going to be even more habitable as the years go by.
Pratika Dayal points out that the future version of the space will be a better place for planets to take shape and evolve. She studies the evolution of young galaxies, at the University of Groningen, in the Netherlands.
As the level of dangerous radiation given out by dying stars drops and star formation stops happening so often, the result is an environment twenty times more livable than it was when life on Earth first appeared.
The number of small, dim stars, like our sun increases the chances of life evolving somewhere in the future. Seen from this perspective, life on Earth is very early regarding space history.
Our sun is a yellow dwarf, in other words, it is a small, faintly lit star. This type of star is very common in space. They have long lifespans, and they make up the majority of the stars in the Milky Way.
Astronomers are puzzled by the fact that liquid water forms close to red dwarfs. This is because these stars, just like our sun, have intense activity early in their evolution, which sends waves of radiation and flares towards the planets orbiting nearby.
Scientists are still at odds on whether life can evolve despite these extremes. The answer is on its way, within a few decades. Instruments like the Transitting Exoplanet Satellite Survey or the James Webb Telescope are the tools of the future. They’re going to measure space parameters better than ever before and give possible answers regarding the evolution of life.
There is growing research evidence which suggests that space’s habitability is increasingly higher than it used to be.
One of the conclusions is that life on our planet took about a billion years to evolve and another three billion years for technology to emerge. So no need to hurry with the hunt for alien life, maybe it’s only beginning to take shape in some distant galaxy corner.
