Alien Life May Survive on Planets Orbiting White Dwarfs Study Finds

Scientists are trying to find the possibilities of life outside the earth. Many such planets have been discovered outside the solar system on which the essential elements of life are present, but so far, life-awakened life has not been found on any other planet. In this episode, another new discovery scientists have been involved. Planets likely to live outside the Earth include planets that are revolving around dwarf white dwarfs. These are stars that have spent their maximum energy and have a little energy left. They become small and remain the shape of the earth and they have a lot of density. But their planets can give shelter to life.

Now scientists say that there may be chances of life on planets moving around the white Dwarf (extinguished stars). Although these stellar relics (White Dwarf) are no longer able to produce any energy, but still their rapid shrinking, habitable areas can give so much time that can start a biological process. This new study challenges the old estimate that says that due to the rapid changing temperatures of the planets present in such systems, they cannot refuse biological processes.

Researchers have designed a model for this which talks about two very important procedures, photosynthesis and ultraviolet (UV)-driven organism. That is, the model shows whether these two procedures may occur in the zone of White Dwarf. This indicates that life may exist around these stars for billions of years.

In the Astrophysical Journal Letters Study Has been published. The team, led by Caldon White, a prominent writer of the study from Florida Institute of Technology, discovered how long a planet like Earth can maintain life supportive circumstances in a fast shrinking environment of a white Dwarf.

White Dwarf is formed when stars like Sun have finished their nuclear fuel and turn into dense remnants. After this, they slowly go through the process of cooling. The result of which is that their habitable areas start shifting inwards. This has a limited time to a planet in which water can remain in existence on that planet. That is, the planet can cherish a life -giving element like water for a short time.

In a period of 7 billion years, scientists saw the planet revolving around a white Dwarf. The study assessed the energy available for photosynthesis and UV-mangoing living during this period. The result came that despite the limited of the habitable area, enough energy to work for both processes was derived from that white dwarf. Therefore, while searching for life outside the earth, White Dwarf cannot be denied anymore.
