Astrobiology: An astronomer's perspective [PDF]
AIP Conference Proceedings, 2014 In this review we explore aspects of the field of astrobiology from an astronomical viewpoint. We therefore focus on the origin of life in the context of planetary formation, with additional emphasis on tracing the most abundant volatile elements, C, H, O, and N that are used by life on Earth.

The Impact of the Temporal Distribution of Communicating Civilizations on their Detectability
, 2017 We use a statistical model to investigate the detectability (defined by the requirement that they are in causal contact with us) of communicating civilizations within a volume of the universe surrounding our location.

The Astrobiology of Alien Worlds: Known and Unknown Forms of Life
, 2020 Most definitions of life assume that, at a minimum, life is a physical form of matter distinct from its environment at a lower state of entropy than its surroundings, using energy from the environment for internal maintenance and activity, and capable of

Frontiers in Microbiology, 2017 Outer space, the final frontier, is a hostile and unforgiving place for any form of life as we know it. The unique environment of space allows for a close simulation of Mars surface conditions that cannot be simulated as accurately on the Earth. For this

Terrestrial atmosphere, water and astrobiology
EPJ Web of Conferences, 2010 Primitive life, defined as a chemical system capable to transfer its molecular information via self-replication and also capable to evolve, originated about 4 billion years ago from the processing of organic molecules by liquid water.
