1d ago
A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST The JWST has the potential to increase our understanding of terrestrial exoplanets and their atmospheres, but the various signal contaminations need to be isolated and quantified. Using JWST Cycle 1 observations of TRAPPIST-1 as a benchmark, this Perspective proposes a series of steps to use future JWST data efficiently for this purpose ..read more

Laboratory infrared spectra and fragmentation chemistry of sulfur allotropes
Nature » Astronomy and Astrophysics
by
1d ago
Laboratory infrared spectra and fragmentation chemistry of sulfur allotropes Sulfur allotropes are proposed to be an important sulfur reservoir in molecular clouds, but spectroscopic data to test this hypothesis are limited. Here the authors measure laboratory far-infrared spectra of cold isolated S molecules, which show a near-perfect match with calculations, and examine their fragmentation pathways ..read more

Detailed study of a rare hyperluminous rotating disk in an Einstein ring 10 billion years ago An extreme Einstein ring ~10,000 times as bright as the Milky Way in the infrared is studied with VLT/ERIS and ALMA, and the authors find that the lensed galaxy is a starburst with a fast-rotating disk, rather than being driven by a major merger ..read more

Assessment of the environmental impacts of the Cherenkov Telescope Array mid-sized telescope According to a life-cycle analysis, the main environmental impacts of building and operating an astronomical telescope are greenhouse gas emissions and the use of mineral resources. Impacts can be reduced by using renewable energy and by making design changes ..read more
