Alien life could exist around dead stars

Scientists believe that the planets surrounding the white dwarf to find signs of life more real than any around other stars. It is possible that dying or have outlived their time, too, can have a star from a theoretical point of view in its orbit exoplanets with well-developed extraterrestrial life.

Such assumptions put forward by scientists from the Harvard-Smithsonian Center for Astrophysics (CFA), the world’s largest astrophysical organization.

If this theory will hold true, and life actually exists, it will be found in the next few decades. The conclusion is based on evidence of a new theoretical study, which examined orbiting white dwarf planet similar to Earth.

Astrophysicists at the research found that if a planet orbits around the white dwarf, in its atmosphere is more likely to detect oxygen than in the Earth-atmosphere of an exoplanet orbiting a star similar to our sun.

"Wanting to find traces of extraterrestrial biological life, we must first learn exactly white dwarfs. Then the probability of finding a habitable ekzomiry we’ll have more," - said the theorist of the Harvard-Smithsonian Center for Astrophysics and director of the Research Institute in Berkeley, Avi Loeb.

When a star like our sun dies, it emits into the environment a lot of different materials and elements and becomes a white dwarf, throwing off its outer layers. Among these elements are present, and the building blocks for biological life.

The white dwarf is usually cooled slowly to disappear for a very long time, but it can at the same time, long enough to keep the heat to heat for billions of years, neighboring worlds to a comfortable temperature for life.
