New discoveries suggest that there are habitable planets outside the Solar System

Data from the large VLT telescope indicate that planets exist around the star L98-59C outside the Solar System.

Indicates new discoveries from a team of European astronomers Planets Habitable, The ability to save and maintain life, outside System Solar.

These findings are consistent with a group of scientists from various European centers who used the large VLT (very large telescope) telescope at the European Southern Observatory in the Chilean Atacama Desert, and published the results in astronomy and journal astronomy.

There are his works Informed The European Southern Observatory (ESO, in English for its acronym), sheds new data Planets What’s around one Star “Near” (called L 98-59) In addition, there is evidence that these planets have some resemblance to planets in the inner region Solar System.

Of these findings, three stand out: a planet Half the mass of Venus So that it is the smallest ever measured; A sea world; A possible planet in a “habitable” region, because it is so far away from the possible star of life.

“The planet in that habitable zone may have an atmosphere that can save and maintain life,” said Maria Rosa Zapatero Osorio, an astronomer at the Madrid Astrobiology Center (CAB-CSIC) and one of the main authors of the study.

The results obtained by the European Southern Observatory – Europe’s leading intergovernmental astronomical organization – now point to a very important stage. Search for life On Earth-sized planets outside the Solar System.

Discovering possible clues to life in the past or present – so-called “biosignatures” in astronomy – Exoplanet It depends on its ability to study the atmosphere, but current telescopes are not yet capable of obtaining the required solution and retrieving information from distant planets.

Some of the planets studied by these scientists orbit the star (L 98-59) only 35 light years away; They are rocks – like the earth or Venus; They are hot enough for her.

Thanks VLT telescopeResearchers have determined that at least three of these planets may contain water in their interior or atmosphere; Two of them – the closest to the star – are mostly dry, and although they may contain small amounts of water, the mass of the third planet may be 30 percent water, making it an “ocean world”.

The ESO team also discovered two other hidden planets that have never been seen in a planetary system far away from a star that allows liquid water to remain on the surface.

In 2019, astronomers have already discovered, from NASA’s satellite, tracking exoplanets, three planets in this stellar system (L98-59).

But for space scanning to continue, and especially for this planetary system, astronomers are focusing on NASA’s next James Webb Space Telescope and the European Southern Observatory’s Atomic Telescope (ELT). It will not start early until 2027.

Olivier Dimanzion, a researcher at the Institute of Astrophysics and Space Sciences at the University of Portugal (Portugal), said:

“As a society since the birth of astronomy, we have been following the planets. The researcher stated in a note released by ESO.
