Nitrogen transformations in microbial mats: Implications for microbial evolution on Earth and the search for life elsewhere Oksana Coban NASA Ames Research Center Microbial mats are thought to have originated around 3.7 billion years ago in the areas around submarine hydrothermal vents, which also believed to exist on Europa, Enceladus and earlier on Mars.  They […]

Aerosols in Planetary Atmospheres Peter Gao NASA Ames / UCB Abstract: The formation of aerosols – condensation clouds and photochemical hazes, for example – are common place in the atmospheres of Solar System planets, from the sulfuric acid clouds of Venus to the organic hazes of Pluto. Recent observations have shown that aerosols may be […]

The Anatomy of the Blue Dragon: Changes in Lava Flow Morphology and Physical Properties Observed in an Open Channel Lava Flow as a Planetary Analogue

Alexander Sehlke NPP Fellowship/USRA The transition of lava flows from smooth pahoehoe to rough `a`a is commonly documented for Hawaiian lavas, and is governed by the rheological conditions of the lava. The rheology of the lava itself depends on the physical properties, such as temperature, density, and crystallinity, and therefore should also apply to any […]

The Geologic Record of Lakes on Mars Timothy A. Goudge (Postdoctoral Fellow)The University of Texas at Austin Decades of planetary exploration have revealed widespread evidence for ancient aqueous activity on Mars, including deeply incised valleys, paleolake basins, and secondary alteration minerals. Lake basins on Earth provide some of the most detailed records of past aqueous […]

The Titan Haze Simulation experiment on COSmIC: investigating Titan’s atmospheric chemistry at low temperature Sciamma O’Brien, Ella M. (NASA Ames Research Center)  Titan is the largest satellite of Saturn and is the only object in the outer solar system with a dense (1.5 bar at the surface) atmosphere. In Titan’s atmosphere, mainly composed of nitrogen […]

Imprints of forming giant planets — hydrodynamic simulations and observations of circumplanetary disks Judit Szulágyi (ETH Zurich)   Recently, younger and younger planets were detected, often still embedded in gaseous circumstellar disks. In this evolutionary phase, giant planets are still surrounded by their own disk: the circumplanetary disk. Even though there is no direct observation […]

Tectonics on Pluto’s moon Charon On May 1st 2017, Icarus journal published a special issue focusing on science results of the New Horizons flyby of the Pluto system in July 2015. Several Ames-based researchers have published first-author studies within this issue. One such study is the investigation of the variety of extensional tectonic features that […]
