EANA International Spring School: Hydrothermal Vents
EANA is celebrating its 20-years anniversary by organizing several special events throughout 2021.

Hydrothermal systems are crucial environments for astrobiology: they are thought to be the theatre of life's origins, host unprecedented polyextremophilic biodiversity, and are key targets in the search for life throughout the Solar System, especially on Mars and icy moons.

Here you can find the recorded lectures of the first EANA online school on hydrothermal systems:

IJA Special Issue - Celebrating 20 Years of EANA
We are delighted to invite you to submit an original research article to the upcoming EANA Anniversary Special Issue in the International Journal of Astrobiology - "Open Questions and Next Steps in Astrobiology in Europe - Celebrating 20 Years of EANA".
Many of you have been part of the EANA family for many years (some from the beginning), and followed the development of the European Astrobiology Network Association into the strong community that we are now. This year, EANA now celebrates its 20th anniversary during the annual meeting that will be hosted online from Porto, Portugal (7-10 September, 2021). EANA will organize a number of events to celebrate its first successful 20 years and its aim to develop astrobiology in Europe and promote collaboration among EU astrobiologists.
The Special Issue will include perspectives from past and present presidents of EANA, historical description of the European network, reviews, and research papers outlining the latest European research in astrobiology, especially in the context of the new and next astrobiology mission to Mars, and in the perspective of the Mars Sample Return Missions.
Join us in celebrating 20 years of EANA by submitting you research paper to the EANA Anniversary Special Issue.

To better plan the diversity of research subjects and research groups for the special issue, we would be grateful if you could indicate (if you haven't done so already) your interest via e-mail to until 16 April 2021 with a title and short abstract of the envisioned manuscript. The submission deadline for the full manuscript is 15 September 2021.

We look forward to many contributions from the EANA community,
Barbara Cavalazzi, Frances Westall, Lena Noack, Ruth-Sophie Taubner, Tetyana Milojevic, and Kai Finster (guest editors of the special issue)

EANA 2021 - registration now open
The EANA 2021 website is now up and running! The EANA 2021 - Virtual Conference will happen from September 7-10, 2021.
The deadline for registration is September 6, 2021, and the deadline for abstract submission is July 2, 2021.

The European Astrobiology Network association (EANA) celebrates its 20th anniversary this year. In addition to this landmark, Portugal was going to be the host country of an EANA meeting for the first time. Due to the Covid-19 pandemic, the EANA meeting will be online, but we will certainly have plenty of reasons to celebrate and have an exciting event! The virtual EANA 2021 meeting will connect the international Astrobiology community, with an exciting and interactive programme for four half days from September 7-10, 2021 (2pm to 6pm (CET) every day). The virtual meeting consists of invited keynote presentations, several oral presentations (to be submitted by the participants), our well-known Space Factor student contest, as well as poster presentations. EANA 2021 is organized by the EANA 2021 LOC and the EANA Executive Board.

Please consult the website for further information, and forward this message to possibly interested colleagues.

Milojevic et al. (2021): Chemolithotrophy on the Noachian Martian breccia NWA 7034 via experimental microbial biotransformation

Nat Commun Earth Environ 2021, 2, 39, DOI:10.1038/s43247-021-00105-x

Link to paper

Multiple lines of evidence indicate an active hydrogeological history of Mars and chemolithoautotrophy-suited environments within its Noachian terrains. As a result, one of the primary aims of upcoming missions to Mars is to search for signs of ancient life. Here we report on laboratory-scaled microbially assisted chemolithoautotrophic biotransformation of the Noachian Martian breccia Northwest Africa (NWA) 7034 composed of ancient (~4.5 Gyr old) crustal materials from Mars. Nanoanalytical hyperspectral analysis provides clues for the trafficking and distribution of meteorite inorganic constituents in the microbial cell. We decipher biomineralization patterns associated with the biotransformation and reveal microbial nanometer-sized lithologies located inside the cell and on its outer surface layer. These investigations provide an opportunity to trace the putative bioalteration processes of the Martian crust and to assess the potential biogenicity of Martian materials.
