Comparison between habitable zones
Comparison of the Solar System (upper panel) and the planetary system of the red dwarf star LP 890-9 (lower panel) in terms of the stellar radiation received by each of the planets (the unit value is the flux of radiation from the Sun received by the Earth). The habitable zone is defined by the region in blue. The exoplanet under study LP 890-9 c is located in the vicinity of a transition region with the orbital zone of Venus in relation to the Sun (yellow in the figure). A planet in this region is more likely to develop a climate similar to what we see on Venus today.

Schematic representation of the orbit of the exoplanet LP 890-9 c and of the radiation emitted by the planet in a specific band of the electromagnetic spectrum. This information, obtained with the atmospheric model in three dimensions, is used to calculate the variation of the radiation received by an observer on Earth throughout the orbit of this planet. The planet and the star are not at scale.

Image of Venus in the ultraviolet band of the electromagnetic spectrum
Image of Venus in the ultraviolet band of the electromagnetic spectrum, taken with the Japanese Space Agency’s (JAXA) Akatsuki probe. The ultraviolet radiation reveals the appearance of Venus on top of the planet’s cloud layer.
