Scientists have discovered a total of five planets around the star L 98-59, 35 light-years from Earth. There may be water on several surface.

“We have evidence of an Earth-like planet in the system’s habitable zone,” said Olivier Demangon, a researcher at the Institute of Astrophysics at the University of Porto in Portugal, the study’s lead author. The expert believes that the discovery of a celestial body outside the solar system, similar in size to the Earth, is an important step in the research after life.

This planet may have an atmosphere capable of supporting life

said Maria Rosa Zapatero Osorio of the Center for Astrobiology in Madrid.

The ESPRESSO spectrometer from the European Southern Observatory’s Very Large Telescope (VLT) in Chile has detected a planet half the mass of Venus. It is the closest celestial body to the center of the star system L 98-59, and the lightest exoplanet whose mass has been measured using radial velocity measurement.

the Astronomy and astrophysics According to the authors of the study presented in the scientific journal, their discovery is the result of a technical breakthrough. “Without the accuracy and stability provided by Espresso, this measurement would not have been possible. This is a serious step in being able to measure the mass of the smallest exoplanets,” said Zapatero Osorio.

They also identified a planet in the habitable zone that could probably be called an ocean planet: up to 30 percent of its mass could be water. The other two planets, which orbit near the star L 98-59, are likely to be dry, but may contain small amounts of water.

According to measurements by NASA’s satellite called NESS, the three planets orbiting L 98-59 have a size of 0.85-1.52 times the size of Earth. Espresso determined the density of the planets, from which conclusions can be drawn about the water content in the celestial body.

They also discovered a fourth planet and hypothesized a fifth planet already far enough from the star to have water on its surface.
