Find out the most Earth-like alien planet ever

In the distant star system Teegarden, there are two exoplanets that are candidates for finding life beyond Earth.

According to a new report, scientists discovered a planetary exoplanet (exoplanet - an extrasolar planet) in a star system near us, which is about the same size as the Earth. There are two reasons for the discovery of alien planets that interest us:

1. Thinking that mankind might one day move the Solar System to settle in a distant promised land.
2. It may be a place where living creatures exist. I will not be alone in the universe anymore.

But the new pair of planets, Teegarden b and Teegarden c , have differences compared to all the extrasolar planets we have seen before: one of them resembles strange Earth.

According to preliminary calculations, this is a sunset picture on Teegarden b and c.

At Teegarden, its central star is very cold, inactive, 12 light years away, and ranked 24th among the stars closest to the Sun. During the observation of Teegarden, scientists discovered evidence of a pair of orbiting planets around a cold star. The rate of discovery of life outside of the Earth increased slightly.

' After discovering the existence of two planets, we will continue to study related factors ,' said Guillem Anglada-Escude, an astronomer at Queen Mary University. Basically, they will have to find more evidence to be able to affirm that these two planets are good candidates for life.

' Maybe during the observation process, we will discover more features of the atmosphere here, to see if they really resemble our Earth '.

The researchers obtained this result thanks to CARMENES , a telescope measuring system mounted on a telescope located at the Calar Alto Observatory.

Their size is about 1.1 times the Earth, the time around the central star is respectively 4.91 days and 11.4 days.

The Teegarden star is quite small, the size is only 9% of the solar mass, around 2,900 Kevin (about 2,623 degrees Celsius, more than half the Sun's temperature), is thought to be cold compared to the average temperature star. CARMENES discovered that the color spectrum changed due to gravity from a planet orbiting a star, thereby finding evidence of the existence of two planets, named Teegarden b and c. Their size is about 1.1 times the Earth, the time around the central star is respectively 4.91 days and 11.4 days.

According to the research report published in Astronomy and Astrophysics, Teegarden b is more noticeable when there is the highest measure of Earth Similarity ever . But they immediately corrected: the measure does not reflect the amount of energy the planet absorbs from the central star, not pointing out the elements in the planet's atmosphere - these are the two prerequisite factors for whether Life can exist.

The astronomy industry has achieved much success in detecting exoplanets, but according to the researcher Anglada-Escude, we are still in the early stages. The current telescope is not capable of giving us more specific observations, requiring promising systems like the James Webb Space Telescope or the Extra Large Telescope.

' Somewhat disappointed when we could not figure out anything from discovering the two exoplanets, because their radius was not measured specifically, but this is still a remarkable finding ,' said Amy Barr. Mlinar, an old scientist at the Planetary Science Institute, said.

Until we have the tools to see the distant stars, we have to be content with what we have. Sometimes I feel that science is going too far, but sometimes I feel sad when I know that science has not reached the peak of discovery.
