Nano-DSF glass capillaries filled with different brines. Crystallisation processes can be observed at the extremities of the capillaries. The red arrow indicates extensive crystallisation at the extremity of the capillaries containing the M1 brine. However, crystallisation was not limited to the M1 brine but to all of them. It could be observed both at the extremities and within the capillaries. -- Science Reports via PubMed

Examples of the template extraction from the atmospheric models at JWST’s spectral resolution (top panels) for three molecules, H2O (left column panels), CH4 (middle column panels) and CO (right column panels), using three different normalization approaches. The second, third, and final rows show the resulting normalized templates using the polynomial fitting, Gaussian, and high-pass frequency filtering approaches, respectively. -- astro-ph.EP
