Plot of the various HZ limits (solid red and blue lines) and the evolution of instellation and effective temperature at the orbiting distance of each of the outer planets from

Laminations interpreted as microbial mat remains. A. Outcrop image of microbial mat laminations (dark layers) interbedded with medium- to coarse grained sandstone of the 3.22 Ga Moodies Group, South Africa

This composite image combines observations from the NASA/ESA/CSA James Webb Space Telescope of the Phantom Galaxy (M74) with a high-resolution simulation of galactic turbulence. The simulation from this study —

AU Mic Lyα, O I, and C II light curves observed by HST/STIS in May 2023 around the transit of AU Mic c. The gray region indicates the white-light transit

EPyC-IR spectroscopy complements CHEILS reflected light measurement. Earth’s nadirviewed spectrum from 2.5 to 12.5 μm (modeled) is bracketed by EPyC-IR and includes reflected light for 3 μm (opaque due to

Experiments led by Southwest Research Institute’s Dr. Ujjwal Raut have produced evidence to support spectral data recently collected by the James Webb Space Telescope (JWST) showing that the icy surface

JWST GO time allocation for exoplanet science on different Cycles. Representation of the total General Observer (GO) allocated time for exoplanet science on JWST Cycle 1 (released on March, 2021,

HZ prescriptions used in this work: runaway greenhouse IHZ and maximum greenhouse OHZ from Kopparapu et al. (2014); water condensation limit IHZ from Turbet et al. (2023). Over-plotted are the

The Rossiter-McLaughlin effect of WASP-129 Ab, WASP-162b, Qatar-7b, and EPIC 219388192b. The observed data points (black) are shown with their error bars. The systemic and Keplerian orbit velocities were removed.
