Looking to the future of exo-Earth imaging from the ground, core technology developments are required in visible extreme adaptive optics (ExAO) to enable the observation of atmospheric features such as […]
Carbon monoxide was recently reported in the atmosphere of the hot Jupiter WASP-39b using the NIRSpec PRISM transit observation of this planet, collected as part of the JWST Transiting Exoplanet […]
Waste gas products from technological civilizations may accumulate in an exoplanet atmosphere to detectable levels. We propose nitrogen trifluoride (NF3) and sulfur hexafluoride (SF6) as ideal technosignature gases.
In a companion paper, we introduced a publicly-available pipeline to characterise exoplanet atmospheres through high-resolution spectroscopy.
![Time series of spectra in Order 46 (1643 to 1695 nm) at subsequent steps of the data processing as detailed in Sections 3.1 and 3.2. From top to bottom: [a] Blaze- and telluric-corrected APERO-provided spectra (prior to step (i) in Section 3.1); [b] spectra corrected from the master-out template (step (i) in Section 3.1); [c] Normalised spectra (step (ii) in Section 3.1); and [d] PCA-corrected spectra (with 8 components removed; see Section 3.2). Note that time series of normalised spectra cleaned with the auto-encoder, visually similar to the bottom panel, is not shown here. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2023/08/ATMOSPHERIXI.png?resize=1200%2C719&ssl=1)
Atmospheric characterisation of exoplanets from the ground is an actively growing field of research. In this context we have created the ATMOSPHERIX consortium: a research project aimed at characterizing exoplanets […]
Very young massive planets are sufficiently luminous by their internal heat of formation to permit detailed studies, including spectroscopy of their atmospheres with large telescopes at sufficient resolution (λ/Δλ≳1000) to […]
A weak absorption feature at 2.07 μm on Europa’s trailing hemisphere has been suggested to arise from radiolytic processing of an endogenic salt, possibly sourced from the interior ocean.
The James Webb Space Telescope (JWST) will enable the search for and characterization of terrestrial exoplanet atmospheres in the habitable zone via transmission spectroscopy.
Understanding the set of conditions that allow rocky planets to have liquid water on their surface — in the form of lakes, seas or oceans — is a major scientific […]
Editor’s note: A key aspect to understanding a new location during an Away Team Mission is understanding the local atmosphere and how it is affected by – and influences – […]
