Calculated albedo of K2-18b for the median values of Pcloud, T, CH4, and CO2, for three different instrumental offset cases (Table 1) (Madhusudhan et al. 2023). With a perfectly reflecting

A graphical summary of our most important findings with emphasis placed on the origin, fate, and context of “missing ammonia” in the atmosphere of TOI-270 d. Numbers indicate a sequence

K2-18b – Cambridge University Astronomers have detected the most promising signs yet of a possible biosignature outside the solar system, although they remain cautious. Using data from the James Webb

The mid-infrared transmission spectrum of K2-18 b obtained with the JWST MIRI LRS instrument. The data points with error bars (in brown) show the observed spectrum as described in section

In 2016, scientists discovered that water is released from the Moon during meteor showers. When a speck of comet debris strikes the moon, it vaporizes on impact, creating a shock

In the technique known as “environmental DNA metabarcoding,” probes are designed to target specific DNA fragments, similar to how anglers use specific bait to catch a particular species. The challenge
