Upcoming Talks

The molecular trail of life: From interstellar prebiotics to biomolecules on planets

  • Date: Dec 8, 2021
  • Time: 16:15
  • Speaker: Dr. Niels F.W. Ligterink (University of Bern)
Life as we know it revolves around molecules and a key question is "How do the first biomolecules form?". They may form in some primordial soup on planets, but perhaps their origin is older and out dates the formation of planetary systems.In this talk I will follow the molecular trail of life in space and look at two distinct snapshots. First, the Atacama Large Millimeter Array (ALMA) is used to investigate the prebiotic molecular inventories of star-forming regions. These prebiotic species are linked to the formation of biomolecules and as such can aid the emergence of life on planets and moons. This work shows that star- and planet-forming regions are teeming with a large variety of prebiotic molecules.Second, we stay near our "small, spinning fragment of Solar driftwood" and aim to detect biomolecules on nearby planets (Mars) and moons (Europe). For this we require ultra-sensitive instruments on space exploration missions. To achieve this goal, we developed the ORIGIN instrument, a Laser Desorption Mass Spectrometer that can detect large non-volatile biomolecules that may be present on planetary surfaces. Our studies with ORIGIN demonstrate that it is capable of measuring trace amounts of amino acids, PAHs, and lipids, and thus can assess the state of a primordial soup or even infer the presence of life.

Molten exoplanets as a window into the earliest Earth

  • Date: Nov 17, 2021
  • Time: 16:00
  • Speaker: Dr. Tim Lichtenberg, Department of Atmospheric, Oceanic and Planetary Physics at the University of Oxford, UK
Due to the absence of a reliable rock record from the Hadean, our understanding of the planetary environment that gave rise to life on the earliest Earth is clouded. Upcoming exoplanet surveys, however, will significantly widen our view of the distribution and variability of rocky planets and their chemical inventories, giving opportunity to test scenarios of early planetary evolution. I will describe efforts to establish a comprehensive theoretical framework to simulate the coupled evolution of solidifying planetary mantles and their outgassing atmospheres on young rocky worlds for a wide range of instellation, mass, and composition. In combination with statistical data on a population level and detailed characterisation of individual high-temperature planets, this will enable us to infer the climatic and geodynamic properties of clement, rocky worlds. I will conclude with an outlook on how inferences on the climate and geochemistry of rocky exoplanets may open the path to constraining the formation and earliest surface environment of our own planet.
