Discover the sign of life on a distant star! – Iranian and world news

The discovery of this molecule in the star, called phosphine, has now created doubts about its use as a biological marker in other planets and moons such as Venus, according to .

Molecular phosphine contains one phosphorus atom and three hydrogen. Pure phosphine is odorless, although its commercial grids smell of garlic or spatal fish. The article is highly flammable and exploded may explode.

It is produced only by living creatures (or by synthesis in the chemical industry). For this reason, many believe that its existence in distant planets can be a sign of some kind of life there.

A group of researchers thought in the 6th year they were observed in the Venus atmosphere. This was surprised because the phosphine breaks early, so if there is a planet, a substance will be constantly renewed.

As a result, some researchers estimated that there is probably a form of life in production. However, the researchers already knew that phosphine was discovered in the atmosphere of Jupiter and Saturn through non -living chemical processes in the depths of their atmosphere.

For this reason and, of course, other reasons for phosphine cannot be automatically regarded as life. The heavenly bodies of the brown dwarf are known as failed stars, which are smaller than needed to start ordinary hydrogen fusion but are larger than planets. At a young age, these small stars fueled some dootrium (heavy hydrogen isotope), but the process stops quickly.

For this reason, they shine with low light so that the levels of the youngest and largest may reach 2 degrees Fahrenheit or 2 degrees Celsius. These brown dwarfs mainly shine in the infrared area, and so telescopes such as James Web are very suitable for them. Inside these dwarfs, hot gas circulates in synchronized rings and moves chemicals into their atmosphere.

Some models now predict that brown dwarfs and “hot customers” that are very massive planets outside the solar system are likely to have phosphine.

To investigate if the model has water, the James Webb space telescope examined a brown dwarf at a temperature of between 2 and 2 degrees Celsius. Studies by this space telescope showed that phosphine is found on the Wolf 4C (a brown dwarf at 2 ° C). This discovery raised many questions why phosphine is only in this heavenly body. The physics of astronomers are now confused, but one of the assumptions is that the Wolf 4C is very old and low -key and may have changed its internal chemicals.
