How life started on Earth is a long-time unsolved mystery. There are various hypotheses ranging from outer space to seabed.
Water/Hycean Worlds & Oceanography
Super-Earths and Earth-like Exoplanets
In the last few years astronomical surveys have expanded the reach of planetary science into the realm of small and dense extrasolar worlds. These share a number of characteristics with […]
Distinguishing Potential Organic Biosignatures on Ocean Worlds from Abiotic Geochemical Products using Thermodynamic Calculations
The search for life in our solar system often involves efforts to detect organic molecules, which have been found on many extraterrestrial bodies, including planets, moons, meteorites, comets, and asteroids. […]
Listening To A Non-human Intelligence Talk: Sperm Whale Vocalisations
Sperm whales (Physeter macrocephalus) are highly social mammals that communicate using sequences of clicks called codas. While a subset of codas have been shown to encode information about caller identity, […]
Limited Adaptability Makes Freshwater Bacteria Vulnerable To Climate Change
Freshwater resources are limited, accounting for only 3.5% of Earth’s water, with just 0.25% accessible on the surface. Nevertheless, freshwater lakes are essential for ecosystem functioning and global carbon cycling […]
A Simplified Model for the Forced Libration of Icy Moons with Subsurface Oceans: Application to Enceladus and Mimas
In this work, we investigate a minimalist model capable of accurately replicating the forced librations of an icy moon with a subsurface ocean.
Impact of Planetary Parameters on Water Clouds Microphysics
Potentially habitable exoplanets are targets of great interest for the James Webb Space Telescope and upcoming mission concepts such as the Habitable Worlds Observatory. Clouds strongly affect climate and habitability, […]
Ocean Planet Mapping: On The Way To A Complete Seafloor Map For Our Homeworld
At least twice in the last 20 years, nuclear submarines have collided with previously unknown underwater mountains called seamounts. The reason: they were not on any nautical charts. Just last […]
A Weak Magnetic Field May Have Supported The Diversification Of Life On Earth
An unusual reduction in the strength of the Earth’s magnetic field between 591 and 565 million years ago coincided with a significant increase in the oxygen levels in the atmosphere […]
Webb Telescope Probably Didn’t Find Life On An Exoplanet – Yet
Recent reports of NASA’s James Webb Space Telescope finding signs of life on a distant planet understandably sparked excitement. A new study challenges this finding, but also outlines how the […]
