Scientists have long speculated about the potential habitability of Venus, not at the 700K surface, but in the cloud layers located at 48–60 km altitudes, where temperatures match those found on […]
Fossils don’t always come in large, dinosaur-sized packages. Microfossils refer to a type of fossil that is so small, it can only be perceived with a microscope. These microfossils can […]
Simulating realistic observations of exoplanet atmospheres requires consideration of several physical, astronomical, and technological aspects. The composition and physical structure of an atmosphere has to be modeled using three dimensional […]
The discovery of phosphine in Venus’ atmosphere provides lessons for the search for life. The detection has survived all challenges and has acquired independent support from archival data from PVP.
A Danish amber collector’s find upon a wild North Sea shore in the 1960’s has proved to be of great and surprising significance. After having thoroughly examining the roughly 40-million-year-old […]
Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually […]
Editor’s note: with the future advent of powerful telescopes that may be able to resolve habitable worlds in images composed of a few pixels, large biological phenomena such as algal […]

Telescope missions are currently being designed which will make direct imaging of habitable exoplanets possible in the near future, and studies are needed to quantify the detectability of biosignature features […]
During its flyby of Earth on 20 August, ESA’s Jupiter Icy Moons Explorer (Juice) found ingredients for life in Earth’s atmosphere.
