Verburg, Dylan (author)On the 14th of July 2013, a methane peak was observed in the Gale crater. This methane peak has been investigated in a non-biological context before. This study applies exoplanet research strategies and knowledge about biological methane production on Earth to investigate the biological context. Bayes formula is the foundation of the Bayesian...master thesis 2023

Nathan, Erica (author), Balachandran, Katiyayni (author), Cappuccio, Paolo (author), Di, Julia (author), Doerksen, Kelsey (author), Gloder, Alessia (author), Li, Monica (author), Massarweh, L. (author), Rovira Navarro, M. (author)Enceladus, with its subsurface ocean, is amongst the top priority targets in the search for life beyond Earth. Following on discoveries from the Cassini mission that Enceladus possesses a global subsurface ocean containing salt and organic compounds, there are many unconstrained properties of the ocean and ice shell that must be investigated...journal article 2022

Patty, C. H.Lucas (author), Kühn, Jonas G. (author), Lambrev, Petar H. (author), Spadaccia, Stefano (author), Keller, C.U. (author), Mulder, W. (author), Pallichadath, V. (author), Snik, Frans (author), Stam, D.M. (author)Context. Homochirality is a generic and unique property of life on Earth and is considered a universal and agnostic biosignature. Homochirality induces fractional circular polarization in the incident light that it reflects. Because this circularly polarized light can be sensed remotely, it can be one of the most compelling candidate...journal article 2021

(author), Brogi, M. (author)Exoplanet Proxima b will be an important laboratory for the search for extraterrestrial life for the decades ahead. Here, we discuss the prospects of detecting carbon dioxide at 15 μm using a spectral filtering technique with the Medium Resolution Spectrograph (MRS) mode of the Mid-Infrared Instrument (MIRI) on the James Webb Space Telescope ...journal article 2017

(author)Recently reported results from latest Mars Orbiters and Rovers missions are transforming our opinion about the red planet. That dry and inhospitable planet reported in the past is becoming a wetter planet with high probabilities of water existence in the past. Nowadays, some results seem to indicate the presence of water beneath the Mars surface...journal article 2011

(author), Orzechowska, G.E. (author), Kidd, R.D. (author), Van Sluis, C.A. (author), Foing, B.H. (author)Several robotic exploration missions will travel to Mars during this decade to investigate habitability and the possible presence of life. Field research at Mars analogue sites such as desert environments can provide important constraints for instrument calibration, landing site strategies and expected life detection targets. We have...journal article 2011
