Astronomers find rare Earth-mass rocky planet suitable for the search for signs of life. A newly discovered exoplanet could be worth searching for signs of life. Analyses by a team led by astronomer Diana Kossakowski of the Max Planck Institute for Astronomy describe a planet that orbits its home
A planet with eternal day and night
Detecting such low-mass planets is still a major challenge. Diana Kossakowski and her team at the Max Planck Institute for Astronomy in Heidelberg have taken on this task. As part of the Carmenes project, an instrument was developed specifically for the search for potentially habitable worlds. The Carmenes team is using this apparatus at the Calar Alto Observatory in Spain.
An atmosphere is not only a precondition for the emergence of life from a climatic point of view. It would also protect Wolf 1069 b from high-energy electromagnetic radiation and particles that would destroy possible biomolecules. The radiation and particles either stem from interstellar space or from the central star. If the star’s radiation is too intense, it can also strip off a planet’s atmosphere, as it did for. But as a red dwarf, Wolf 1069 emits only relatively weak radiation.
