Livable World: New Earth-Like Planet Discovered

The new planet is almost the same size as Earth and has a fairly moderate temperature.

Scientists have used the TESS space telescope to discover a new Earth-like planet that lies 40 light-years away. By cosmic standards, this is a close distance.

Scientists believe that this world may be habitable. The results of the study were published in the journal Monthly Notices of the Royal Astronomical Society, reports Space.

The new planet, which has almost the same diameter as Earth, has been named Gliese-12 b. It orbits a small, cold red dwarf star 40 light-years away.

The new world is believed to be a rocky planet and may have a composition similar to Earth. But the most important thing is that the planet revolves around the star in the so-called habitable zone.

This means that there are conditions for the existence of liquid water on the planet and a fairly moderate temperature. This means that the planet could potentially be suitable for life as we know it.

Comparison of the potential size of the planet Gilese 12 b with the size of the Earth. It also shows the different potential appearance of a planet depending on whether it has an atomsphere and what kind of atmosphere it is.

But Gliese-12 b orbits too close to its star. Its orbital period is only 12.8 Earth days. However, the red dwarf star is much smaller and much cooler than the Sun. Also, this star does not have strong activity and does not emit too strong fluxes of radiation.

Scientists have found that Gliese-12 b receives approximately 85% of the radiation Venus receives from the Sun. And despite this, the temperature on the planet, according to scientists, is approximately 42 degrees Celsius.

For comparison, the temperature on Venus is 464 degrees Celsius. Scientists also believe that the new world receives approximately 1.6 times more radiation from its star than the Earth from the Sun. The average temperature on our planet is approximately 15 degrees Celsius.

Scientists still remain cautiously optimistic about the potential habitability of the planet Gliese-12 b. The fact is that it is not yet known whether it has an atmosphere. And if it does exist, what exactly is it? And this is an important factor on which depends whether this planet can be suitable for life. For example, Venus, like the Earth, is also located in the habitable zone of the Sun, but this is a world with hellish conditions.

But scientists believe that the planet Gliese-12 b may still be habitable. The study’s authors suggest that the planet may have an atmosphere, although it is thin. But in fact, the lack of a dense atmosphere is a good sign for the existence of potential extraterrestrial life there.

Scientists say that the temperature of 42 degrees Celsius is the average parameter for a planet without an atmosphere; if there is an atmosphere there, then the average temperature may be lower.

Now we need to accurately determine the presence of an atmosphere on the planet Gliese-12 b and its chemical composition, which will give clues as to whether this world is suitable for life or not. To do this, scientists are going to use the Webb Space Telescope.
