Titan, the only body in the solar system aside from Earth with standing liquids on its surface, has high-latitude hydrocarbon lakes and seas. As Titan’s atmosphere generates light winds, there […]
Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain life-supporting atmospheres, focusing on size and atmospheric dynamics.
The Habitable Worlds Observatory (HWO) will provide the first opportunity to directly image and spectrally characterize terrestrial exoplanets in the habitable zones of nearby stars.
ESA’s Ariel Space Mission will characterise the atmospheres of approximately 1000 exoplanets to quantify population-level trends.
The Hubble Space Telescope inaugurated the era of exoplanet atmospheric characterization. While the James Webb Space Telescope has largely taken up the mantle of infrared atmospheric characterization, Hubble’s unique short-wavelength […]
In the region where the ExoMars Rosalind Franklin rover will search for signs of life, clay deposits extend beyond previous estimates, a new study finds. One hypothesis even suggests a […]
Zonal flows in planetary atmospheres are ubiquitous, and nearly all the planets in the Solar System have flows that are zonally rather than meridionally aligned. Jets, which are essentially concentrated […]
The first mission devoted to observing the Martian atmosphere and its evolution, NASA’s MAVEN (Mars Atmosphere and Volatile Evolution), has ended after more than 11 years in orbit at Mars […]
Probing the atmospheres of young exoplanets offers a powerful window into how planetary systems evolve and the physical and chemical processes that drive those early evolutions.
Recent observations reveal that atmospheric compositions of close-in sub-Neptunes are diverse and can differ strongly from pure H/He-dominated.
