New research helps detect life outside the Solar System

The American Journal of Austrophysical has just published the results of research by scientists from the US Aerospace Agency (NASA) on a new model to reduce the time to identify exoplanets. The solar system is capable of survival.

Expert Yuka Fujii, who works at the Goddard Space Research Institute, NASA and team leader, said using a model to simulate the actual atmospheric conditions , his team discovered a new process. control the life of extrasolar planets, thereby helping to identify potential planets that need to be further studied.

Previous studies often had to rely on a one-way and vertical model to simulate atmospheric conditions. According to NASA, the new study uses a model to calculate conditions in three-dimensional space, allowing scientists to simulate atmospheric circulation and special characteristics of circulation, which models One-dimensional space cannot be done.

Experts say liquid water is extremely important for life.

Experts say liquid water is extremely important for life. If the temperature in an area is unknown to allow liquid water to exist for a long enough time for life to grow, then there is potential for life.

If a planet is too far away from its star, surface water on the planet will freeze, if the mineral is too close, surface water will evaporate into the universe. This occurs when water vapor rises in the upper layer of the atmosphere called the stratosphere and leads to the breakdown of hydrogen and oxygen-forming atoms under the action of ultraviolet rays from the star. Then extremely light hydrogen atoms could fly into space. The planet is in the process of losing oceans in this way and is determined to enter a wet-greenhouse state due to the wet stratosphere on the surface.

For extrasolar planets orbiting maternal stars, the team detected heat from infrared (NIR) from this process that could increase the humidity in the stratosphere over time. Therefore, it is possible that extrasolar planets near the parent star may have life. This is a new discovery that is completely different from the old model findings.

According to the scientists, the new research method shows that since maternal stars emit a large amount of light according to NIR wavelengths, the wet greenhouse condition will give the climate more hotter than the heat zone at Earth.

In the future, the team will change planetary properties such as gravity, size, atmospheric composition and surface pressure to see how they affect circulation and storage capacity. Pine of steam.
