Thirty years after the discovery of the first exoplanet, we detected more than 7000 of them in our Galaxy. But there are still billions more to be discovered! At the same time, exoplanetologists have begun to take an interest in their characteristics,

The study of exoplanets has come a long way since the first detection of a planet orbiting a star other than the Sun in 1995. This groundbreaking discovery, achieved through the radial velocity (RV) technique,

Astronomers who identified HD 20794 d say its proximity to its host star and orbital pattern suggest it could hold water.

An international team, including researchers from UNIGE and NCCR PlanetS, has discovered a super-Earth, referred to as HD 20794 d, located about 19.7 light-years away from Earth. This planet is larger than Earth and orbits a G-type star similar to the Sun.

But according to an international team of researchers, including some from the University of Geneva, in a study published Tuesday in Astronomy & Astrophysics believe the super-Earth, dubbed HD 20794 d, could offer new insights into what makes a planet capable of supporting life.

Earth” planet that may have conditions suitable for life. The planet is outside our solar system and has a mass six times greater than that of Earth. The discovery is of an exoplanet, this is any planet beyond our solar system,

Are they exo terrestrials? Mars is apparently not the only planet on our radar capable of sustaining life. UK researchers have confirmed the existence of a “super-Earth” located 20 light-years away that could reveal the existence of extraterrestrial beings,

Earth”, which could be home to alien life. The planet, known as HD 20794d, orbits in the habitable zone of a star similar to the sun, and is 20 light years away from our solar system - making it a close neighbour in a galaxy that spans 105,
