According to a new study, the technology planned for the future space mission ‘Life’ is suitable for the discovery of life-friendly planets. It was tested on Earth – with an unsurprising result: life is possible on Earth.
For the study published Monday in the journal “The Astrophysical Journal,” researchers from the University of Zurich (UZH) and the Swiss Federal Institute of Technology in Zurich (ETH Zurich) considered Earth an exoplanet about 30 light-years in size . away from the object being observed.
This allowed the team to detect concentrations of the atmospheric gases CO2, water, ozone and methane in the infrared spectra of Earth’s atmosphere. There are also surface conditions that favor the presence of water.
This is encouraging, ETH Zurich wrote in a statement on Monday. If a space telescope like Life were to observe planet Earth, it would find evidence of a habitable world.
With the ‘Life’ mission led by ETH Zurich, researchers want to detect traces of life on exoplanets using a network of five satellites. Life stands for ‘Grand Interferometer for Exoplanets’. (sda)
