We determine optimal requirements for the joint detection of habitable-zone planets and cold giant planets with the Habitable Worlds Observatory (HWO).
Ionizing radiation is known to have a destructive effect on biology by causing damage to the DNA, cells, and production of Reactive Oxygen Species (ROS), among other things.
Methane is a potent greenhouse gas, an important energy source, and an important part of the global carbon cycle. The relative abundances of doubly substituted (“clumped”) methane isotopologues (13CH3D and […]
Microorganisms are essential players in Earth’s ecosystems, demonstrating remarkable adaptability to harsh conditions including arctic ice caps, deep-sea hydrothermal vents, and high-pressure oceanic zones.
The search for habitable, Earth-like exoplanets faces major observational challenges due to their small size and faint signals.
Southwest Research Institute experiments offer a new view on a hydrogen peroxide chemical cycle on Europa. Carbon-bearing species rising to Europa’s icy surface from a subsurface ocean are irradiated by […]
K2-18 b closely orbits a nearby M3 dwarf within its habitable zone, where this planet could be either a super-Earth or a mini-Neptune.
Due to extreme temperatures and the dryness of Mars, it’s thought to be impossible for liquid water to form on the planet’s surface, a critical precondition for habitability. The only […]
The L 98-59 system, identified by TESS in 2019, features three transiting exoplanets in compact orbits of 2.253, 3.691, and 7.451 days around an M3V star, with an outer 12.83-day […]
Planets in the liquid-water habitable zone of low-mass stars experience large tidal forces, 103 to 104 times those on Earth, due to the small distance between the habitable zone and […]
