The group of scientists from the University of Bern and the NCCR PlanetS, ETH Zurich, the European Southern Observatory (ESO), and the University of Reading in the UK decided to demonstrate the long-lasting viewpoint.
Worsening conditions around the globe.
Their analysis of future environment patterns, based upon high-resolution global climate designs, reveals that significant huge observatories from Hawaii to the Canary Islands, Chile, Mexico, South Africa, and Australia will likely experience an increase in temperature level and atmospheric water material by 2050. This, in turn, might indicate a loss in observing time as well as a loss of quality in the observations.
” Nowadays, astronomical observatories are designed to work under the existing site conditions and just have a few possibilities for adjustment. Potential effects of the climatic conditions for telescopes, for that reason, include a greater danger of condensation due to an increased humidity or malfunctioning cooling systems, which can cause more air turbulence in the telescope dome”, Haslebacher states.
The reality that the effects of environment change on observatories had not been considered previously was not an oversight, as research study co-author Marie-Estelle Demory says, however was not least due to the state of the art: “This is the first time that such a study has actually been possible. Thanks to the higher resolution of the global environment designs established through the Horizon 2020 PRIMAVERA task, we were able to take a look at the conditions at various areas of the globe with fantastic fidelity– something that we were unable to do with conventional models. These models are important tools for the work we do at the Wyss Academy”, says the senior scientist at the University of Bern and member of the Wyss Academy for Nature.
” This now enables us to say with certainty that anthropogenic climate modification must be taken into account in the website selection for next-generation telescopes, and in the construction and upkeep of astronomical facilities,” says Haslebacher.

The VLTs Laser Guide Star: A laser beam introduced from VLTs 8.2-meter Yepun telescope crosses the stunning southern sky and develops a synthetic star at 90 km altitude in the high Earths mesosphere. The Laser Guide Star (LGS) is part of the VLTs Adaptive Optics system and it is used as a recommendation to remedy images from the blurring effect of the atmosphere. Places for telescopes are chosen with terrific care.

New research study exposes how worldwide warming impacts astronomy.
The clarity of the environment above the website from where the observations are taken has a delicate relationship with the quality of the ground-based astronomical observations. Places for telescopes are picked with excellent care.

In a study presented at the Europlanet Science Congress 2022 in Granada, a group of scientists led by the University of Bern and the National Centre of Competence in Research (NCCR) PlanetS show how one of the greatest problems of our time, anthropogenic environment modification, is now even impacting our view of the cosmos. The study was recently published in the journal Astronomy & & Astrophysics.
A blind area in the choice process.
” Even though telescopes normally have a life time of several years, site choice processes just consider the climatic conditions over a brief timeframe. Typically over the past five years– too brief to record long-term trends, let alone future changes triggered by worldwide warming”, Caroline Haslebacher, lead author of the research study and researcher at the NCCR PlanetS at the University of Bern, points out.
