Scientists Explain: Aliens May Not Need Planets to Live

The question of whether there is life in space is a great curiosity for scientists and researchers. No definitive evidence of life has been found so far. Scientists, who are largely searching for life in places similar to Earth, have revealed that life in space can actually exist without the need for a planet.

Scientists have suggested that there may be life forms in space that do not need a planet to survive.
In their new study, Robin Wordsworth from Harvard University and Charles Cockell from the University of Edinburgh have obtained remarkable findings by examining life forms that could develop in environments outside of standard definitions of life.
The search for life in the Universe has largely focused on the characteristics of life on Earth. However, very few of the approximately 6,000 exoplanets discovered to date have habitable conditions similar to Earth. This situation led researchers to unknown and unusual life forms.
Wordsworth said, “We aim to investigate the limits of non-conscious life,” and stated that simple life forms are not subject to physical limitations beyond the gravity of the planets. This approach is supported by the existence of organisms such as water bears that can survive in the harsh conditions of space. Tardigrades can withstand adverse conditions such as extreme temperatures, radiation and space, suggesting that life may exist in unusual environments.
Researchers argue that these simple organisms that could live in space could develop a protective membrane or shell. Such a structure could help them maintain the low pressure in the space environment. However, certain temperature conditions are needed for liquid water to exist. While the greenhouse gas effect on Earth ensures that water remains liquid, it seems difficult for such an environment to form in space.
On the other hand, some organisms, such as the Saharan silver ant, have the ability to choose which wavelengths of light they absorb and which they reflect. This ability is considered a promising finding in terms of allowing life forms in space to control their temperature. However, the evaporation of light elements in space raises questions about how these organisms could exist without gravity.
Scientists suggest that living colonies could create a sustainable ecosystem in the long term by obtaining resources such as carbon or oxygen from fixed sources such as asteroids. This is considered an important strategy for the continuity of life in space.
As a result, this study offers a new perspective on the possibility of different life forms in the universe. Emphasizing that research should also cover these potential life forms, scientists draw attention to the importance of expanding the search for life in the universe to a wide range. Such findings may enable us to learn more about the existence of life in space in the future.
