• A more comprehensive habitable zone for finding life on other planets
  The habitable zone (HZ) is the circular region around a star(s) where standing bodies of water could exist on the surface of a rocky planet. Space missions employ the HZ to select promising targets for follow-up habitability assessment. The classical HZ defini…

• The Second Law of Thermodynamics, Life and Earth's Planetary Machinery Revisited
  Life is a planetary feature that depends on its environment, but it has also strongly shaped the physical conditions on Earth, having created conditions highly suitable for a productive biosphere. Clearly, the second law of thermodynamics must apply to these d…

• Searching the Moon for Extrasolar Material and the Building Blocks of Extraterrestrial Life
  Due to its absence of an atmosphere and relative geological inertness, the Moon's surface records past impacts of objects from the Solar system and beyond. We examine the prospects for discovering extrasolar material near the lunar surface and predict that its…
