Scientists discover a potentially habitable planet. The length of the year is 8.5 days


Scientists have discovered a potentially habitable planet, with a year of 8.5 days, as scientists have found two types of “super-Earths” about 100 light-years from Earth, according to the newspaper “Metro”.

The two planets were found orbiting TOI-4306 or Speculus -2 It is a small, cold star around which planets have been discovered.

The discovery, made by an international team of scientists led by astrophysicist Laetitia Delris, was published in the Journal of Astronomy and Astrophysics.

first planet, LP 890-9 B or TOI-4306b It is the deepest in the system and was initially identified by a satellite.Transiting a satellite to survey the outer planetshe-goat NASA’s mission is to search for exoplanets orbiting nearby stars.

this second planet, Speculose – 2 c is similar in size to the first and about 40% larger than Earth but has a longer orbital period of about 8.5 days, putting it in a “habitable zone” around its star.

The space agency’s latest space telescope, the Transiting Satellite for Exoplanet Reconnaissance, has been designed.he-goat‘, specifically to search for the so-called exoplanets, those alien worlds outside our solar system.

This planet, which is about 30% more massive than Earth, completes an orbit around the star in just 2.7 days.

Researchers at the University of “Liege” used their ground-based telescopes to search for habitable planets.URtla-cOOl star smashingTo confirm and characterize this planet, and also to deeply examine the system for other planets that may be missing by he-goat.

Delrize explained: “Looking he-goat about exoplanets using the transit method, by observing the brightness of thousands of stars simultaneously, and looking for slight dimming that may be caused by planets passing in front of their stars, however, follow-up with ground-based telescopes is often necessary to confirm the planetary nature of the detected candidates and to improve measurements their sizes and orbital characteristics.

This follow-up is especially important in the case of very cold stars, such as LP 890-9which emits most of its light in the near infrared, which is sensitive to he-goat somewhat limited.

On the other hand, the consortium telescopes have been improved speculus To monitor this type of star with high accuracy, thanks to the highly sensitive cameras in the near infrared.

Michael Gillon, principal investigator for the project, said:speculus‘, the aim of speculus The search for potentially habitable terrestrial planets passing through the smallest and most magnificent stars in the solar neighborhood, such as the planetary system TRAPPIST-1which we discovered in 2016 thanks to an experimental project using a telescope TRAPPIST SOUTHOur own.

These planets are particularly well suited for detailed studies of their atmospheres for possible traces of life using large observatories such as NASA’s James Webb Telescope.

Feedback did not help LP 890-9 not only confirming the first planet, but also made it possible to discover a second, previously unknown planet.
