Strange planet death story helps bring life

When a star dies, its outer layers are gradually evaporated, leaving a hot nucleus called White dwarf - a celestial body created when stars are low and medium.

A new theoretical study has shown that Exoplanets orbiting a dying planet are capable of life.

When a star dies, its outer layers are gradually evaporated, leaving a hot nucleus called White dwarf - the celestial body created when stars are low and medium. " die " (consuming all the nuclear fuel in the star), about the size of the Earth.

White dwarfs often cool very slowly, the temperature it keeps hot and long enough to warm the planet next to for billions of years.

Because white dwarfs are smaller and hotter than the Sun, the orbiting planets need to be close enough to hold water, which is essential for life. Accordingly, a planet orbiting a white dwarf for 10 hours, at a distance of 1 million miles, could have life.

Planets orbiting a dying planet may have life.

'In the search for alien biological signs, the first stars we should notice are dying stars' - Avi Loeb, a Harvard-Smithsonian researcher on astrophysics jelly said.

In order to become a white dwarf, the star undergoes a phase of turning into a "red star" and "engulfing" every nearby planet along its path. In order for a planet to orbit a white dwarf, it must 'wait' until the 'red star' turns into a white dwarf. Many scientists believe that these stars can be formed from the remaining dust and gas or move from the outside into the star's solar system.

According to astronomers, out of the 500 most recent white dwarf planets, one or more Exoplanet (Exoplanet is the planet outside the solar system and it revolves around another star rather than their sun I) will have life. To find these potential planets, astronomers say they need to establish a process to search for cyclic stars when a planet flies over it.

Because white dwarfs are about the same size as the Earth, an Earth-sized planet could capture a large amount of light from a white dwarf to produce clear signals. When the white dwarf's light shines through the surrounding air, the atmosphere absorbs light and produces chemical signals to confirm whether the air contains oxygen and oxygen.

NASA is continuing to develop the James Webb space telescope in hopes of finding exoplanets that orbit the white dwarf. They think that with this glass, just a few hours after discovering that exoplanet, we can confirm whether its atmosphere has steam and oxygen.
