In other solar systems, there may be a new study found on many planets inhabited by alien life.
Studies show that there may be many habitable planets in other parts of the universe, unlike our solar system, where only one of the worlds has the right conditions for life to flourish.
Residents searching for life elsewhere in the universe regularly search for planets in the “living zone” that are far enough away from the star that the water does not immediately evaporate, but close enough not to freeze.

Researchers believe the greatest hope for finding alien life in another universe is to find a planet at some distance from its star, also known as the Goldilocks Zone.
A new study led to a look at a famous, relatively nearby planetary system called Trappist-1
, which has at least three planets in its living area.
“It made me wonder what the largest number of stellar habitable planets is and why there is only one star in our star,” said astrobiologist Stephen Kane of UC Riverside, who led. Journal of Astronomy this week, he said. “That didn’t seem right!”
To understand how many living planets the solar system could support, the researchers developed a model that allowed them to simulate planets of different sizes orbiting stars. This explained how these planets interacted with each other as they orbited their star and continued over a theoretical million-year period.
They found that a star like our Sun can support as many as six planets, each of which has liquid water and is habitable. Other types of stars could support all seven.
If there were more of them, the planets would move too close to each other, disturbing their orbits.
Research has also helped to elucidate the reasons why our planet is home to a relatively small number of living planets, and the conditions that would change that. Part of our problem seems to be that the planets in our solar system are moving in an oval shape – if their path is more regular and circular, they better reduce contact to have a more stable orbit.
Jupiter may also be worth some blame for the fact that our solar system has also become uninhabitable. Research shows that it is so large – twice the mass of the rest of the planet in the solar system – two and a half times that it takes up space and disturbs everything around.
“It has a big impact on the adaptability of our solar system because it’s massive and disturbed by another orbit,” Kane said.
Research could now help identify other solar systems that would be worth exploring for potential life. This could be useful for research by Nasa telescopes, such as the Jet Propulsion Laboratory’s Habitable Exoplanet Observatory, which looks at the universe in an attempt to figure out which worlds might have the right conditions to be at home.
