Extraterrestrial life: Life on Mars – then and now [PDF]
Current Biology, 1996 The recent claim to have discovered evidence of extraterrestrial life on a meteorite from Mars is not compelling, but the study nevertheless has useful heuristic value.

Quest for extraterrestrial life [PDF]
Nature, 2008 In The Living Cosmos, Chris Impey outlines current thinking on how and where we should look for signs of extraterrestrial life. In its 50-year history the science of astrobiology — or exobiology — has made great strides, fuelled by a series of successful Solar System probes.

Microlensing and the Search for Extraterrestrial Life [PDF]
The Astrophysical Journal, 1999 Are microlensing searches likely to discover planets that harbor life? Given our present state of knowledge, this is a difficult question to answer. We therefore begin by asking a more narrowly focused question: are conditions on planets discovered via microlensing likely to be similar to those we experience on Earth?

Expecting the unexpected in the search for extraterrestrial life [PDF]
International Journal of Astrobiology, 2020 AbstractOn p. 10 of the 2018 National Academies Exoplanet Science Strategy document (NASEM 2018), ‘Expect the unexpected’ is described as a general principle of the exoplanet field. But for the next 150 pages, this principle is apparently forgotten, as strategy decisions are repeatedly put forward based on our expectations.

Extremophiles and the Search for Extraterrestrial Life [PDF]
Astrobiology, 2002 Extremophiles thrive in ice, boiling water, acid, the water core of nuclear reactors, salt crystals, and toxic waste and in a range of other extreme habitats that were previously thought to be inhospitable for life. Extremophiles include representatives of all three domains (Bacteria, Archaea, and Eucarya); however, the majority are microorganisms, and

En Route To Finding Extraterrestrial Life
, 2017 The last decade has seen an enormous leap forward in the characterization of extrasolar planet atmospheres, with ground-based telescopes playing a unique and increasingly important role. The prospects for the ELT are extremely exciting, and characterizing rocky exoplanets will be at the heart of its science.
