Direct Detectability Of Tidally Heated Exomoons By Photometric Orbital Modulation
(Aims) We investigate whether volcanic exomoons can be detected in thermal wavelength light curves due to their phase variability along their orbit. The method we use is based on the […]

Volcanic Eruptions May Have Spurred First 'Whiffs' Of Oxygen In Earth's Atmosphere
A new analysis of 2.5-billion-year-old rocks from Australia finds that volcanic eruptions may have stimulated population surges of marine microorganisms, creating the first puffs of oxygen into the atmosphere. This […]
