![Seasonal distribution of methane clouds in Titan’s troposphere. (a) Latitudinal distribution of clouds observed from Cassini and ground-based observatories [6, 54, 105], overlain on the zonal-mean precipitation distribution averaged over 40 Titan years of a simulation with TAM [57]. Vertical dotted lines indicate the timing of solstices (northern winter solstice and northern summer solstice, NWS and NSS) and equinoxes (northern vernal equinox and northern autumnal equinox, NVE and NAE); thin contours denote isolines of diurnally averaged top-ofatmosphere insolation, and grey shaded regions denote latitudes and times of polar night. (b) A simplified illustration of the expected atmospheric circulation during late northern summer leading to upwelling at northern mid-latitudes, which promotes cloud formation there, as observed by JWST and Keck most recently (see Figs. 4 and 5). -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/05/The-Atmosphere-of-Titan-in-Late.png?resize=1200%2C718&ssl=1)
Saturn’s moon Titan undergoes a long annual cycle of 29.45 Earth years. Titan’s northern winter and spring were investigated in detail by the Cassini-Huygens spacecraft (2004-2017), but the northern summer […]

The High-contrast Performance of the Keck Planet Imager and Characterizer
The Keck Planet Imager and Characterizer (KPIC), a series of upgrades to the Keck II Adaptive Optics System and Instrument Suite, aims to demonstrate high-resolution spectroscopy of faint exoplanets that […]
