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

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,

Planets emerge from the dense disk of gas and dust encircling young stars. — NASA Pebble accretion is the leading theory for the formation of exoplanets more massive than the
