In a new study, scientists have discovered huge canyons cutting through the underbelly of Antarctica’s ice shelves, meaning they may be more fragile than previously thought. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.
One of the primary questions when characterizing Earth-sized and super-Earth-sized exoplanets is whether they have a substantial atmosphere like Earth and Venus or a bare-rock surface like Mercury….
We derive fitting formulae for the quick determination of the existence of S-type and P-type habitable zones in binary systems….
We combine inferred galaxy properties from a semi-analytic galaxy evolution model incorporating dark matter halo merger trees with new estimates of supernova and gamma ray burst rates as a function of metallicity from stellar population synthesis models incorporating binary interactions….
The discovery of evidence for ancient sea-floor hydrothermal deposits on Mars identifies an area on the planet that may offer clues about the origin of life on Earth…
Dense seismograph network shows subsurface geyser plumbing structures.
Eccentricity is an important orbital parameter. Understanding its effect on planetary climate and habitability is critical for us to search for a habitable world beyond our solar system….
A new study warns that Melbourne and Sydney should prepare for 50-degree Celsius (122-degree Fahrenheit) summer days under the Paris Agreement global warming limit of 2 degrees Celsius (4 degrees Fahrenheit). The new study assessed the potential magnitude of future extreme temperatures in Australia under Paris targets of an increase in global temperatures of 1.5 and 2 degrees Celsius (3 and 4 degrees Fahrenheit) above pre-industrial levels.
In some areas of the seafloor, a tectonic mystery lies buried deep underground. The ocean floor contains some of the newest rock on Earth, but underneath these young oceanic plates are large swatches of much older continents that have been dislocated from their continental plates and overtaken by the younger, denser oceanic plate. Researchers have been puzzled by this phenomenon for some time: how does a continental plate leave some of itself behind?
The oxidation of rocky planet surfaces and atmospheres, which arises from the twin forces of stellar nucleosynthesis and gravitational differentiation, is a universal process of key importance to habitability and exoplanet biosignature detection….
