Phase folded and offset-subtracted ESPRESSO RVs with the modeled best-fit allesfitter RV curve for HD 35843 b (left) and HD 35843 c (right), with residuals plotted on the bottom. Stellar

Eos Molecular Cloud The Eos cloud, recently discovered in the far ultraviolet via H2 fluorescence, is one of the nearest known dark molecular clouds to the Sun, with a distance

Comparison of glucose (itself non-absorbing) at different time points after its addition to 85% w/w sulfuric acid. The glucose reacts with sulfuric acid and produces rose-pink solution with a single

Comparison of (telluric) molecular oxygen spectrum observed using low-medium resolution spectrograph and interferometer-based instruments. The top panel shows the observed telluric spectrum from archival X-Shooter spectra with spectral resolution ranging

Schematic depiction of an atmospheric temperature profile (dotted line) showing convective regions (blue) and radiative regions (orange). The profile illustrates a detached convective region in the middle atmosphere, separated from

Where Are They? — Grok via Astrobiology.com In this paper we consider the extent to which a lack of observations from SETI may be used to quantify the Fermi paradox.

Micrographs of fresh (a) and 6 day old (b) SD1T cells stained with acridine orange at 1000x magnification (500 nm Ex./526 nm Em.). Bright spots (a) were common among cells. Terminal spores

Panoramic view of the Chang’e-5 landing site. Credit: CNSA/CLEP Polycyclic aromatics are ubiquitous in the interstellar medium and meteorites, yet the search for lunar polycyclic aromatics remains a significant challenge.

Nancy Grace Roman Space Telescope Free-floating planets comprise one of the most enigmatic populations of exoplanets in the Galaxy. Though ground-based observations point to a large abundance of these worlds,
