Scientists discover 24 planets that may be habitable

According to a recent study published in the scientific journal “Astrobiology”, that the universe includes more than twenty planets outside our solar system, which may have life conditions similar to those available on Earth.

A team of scientists from Washington State University in the United States said that there are 24 planets out of more than 4,500 exoplanets known to date that could be candidates for life.

The researchers confirmed that those planets are older, larger, wetter and warmer than Earth, and they are factors that help the development of life in all its forms.

Although these planets are more than 100 light-years away from us, the discovery, according to scientists, may pave the way towards the dream of searching for life in another place in the universe other than Earth.

The British newspaper “Daily Mail” quoted the lead author of the study, Dirk Scholes Moksch, as saying that it is necessary to focus space telescopes such as “James Webb” of NASA, on these planets that have promising life conditions.

According to Dirk, habitability does not necessarily mean that these planets have life, but rather that they are likely to have conditions that would aid life.

The study, stressed that it is necessary to know the age of the discovered planets, as they should not be too old if they are candidates for life, in order to retain heat, in addition to the availability of protective magnetic fields.

The scientists expected that the planets with a mass greater than 1.5 times the mass of the Earth will maintain their internal heating through radioactive decay for a longer period, and they will have a stronger gravity to hold the atmosphere for a longer period of time.

Researchers also believe that an average temperature of 8 degrees Fahrenheit higher than Earth, combined with humidity, would also be good for life.
