We examine the detectability of water (H2O) in the reflected-light spectrum of an Earth-like exoplanet assuming a photometric observational approach rather than spectroscopic.
The most abundant type of planet discovered in the Galaxy has no analogue in our Solar System and is believed to consist of a rocky interior with an overlying thick […]
Our galaxy’s most abundant type of planet could be rich in liquid water due to formative interactions between magma oceans and primitive atmospheres during their early years, according to new […]
The amount of surface water is thought to be critical for a planet’s climate stability and thus habitability.
For decades, scientists believed that Earth’s water originated far from the sun. In the cold outer reaches of the solar system, water-rich bodies formed and later migrated inward, delivering water […]
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have made a first-ever detection of doubly deuterated water (D2O, or “heavy water”) in a planet-forming disk around V883 Ori, a young […]
For decades, scientists have been curious about how much water Mars once had and what led to its gradual transformation into the dry planet we see today.
We demonstrate that the extension of the Habitable Zone (HZ) due to the presence of liquid water on the night side of tidally locked planets, modelled in this and earlier […]
Rotational H2O spectra as observed with JWST/MIRI provide a good probe of the temperature and column density structure of the inner disk. H2O emission can also be influenced by dynamical […]
Organic molecules detected in the watery plumes that spew out from cracks in the surface of Enceladus could be formed through exposure to radiation on Saturn’s icy moon, rather than […]
