“Science Nomad,” Dr. Daniel Angerhausen, Looks for Habitable Planets

By Emily Harari Dr. Daniel Angerhausen is an astrophysicist and astrobiologist at ETH Zürich. Ask him what the oldest question of humankind is and he’ll immediately jump to life on other planets: Are we alone, or are other planets outside our solar system similarly habitable? But Angerhausen doubles back: “That’s also a bit exaggerated. Maybe the oldest question is, ‘Can I eat this?’ But I really think [habitability] is one of the biggest scientific questions and also one that is […]

Pubs: Habitable Zones & Planetary Mass

A new paper led by Dr. Ravi Kopparapu explores the liquid water habitable zone for terrestrial planets and how these limits change with planetary mass. Astronomers are currently interested in identifying extrasolar planets that may be habitable, and calculations such as those led by Dr. Kopparapu help to understand the range of planetary parameters that could retain such conditions. The paper is titled “Habitable zones around main-sequence stars: Dependence on planetary mass” and is available as a pre-print on arXiv.org. […]
