Field Reports
Dale Andersen's Antarctica Field Report 10 December 2013 
I just got off the phone with Dale Andersen who is at Lake Obersee, Antarctica.
Astrochemistry
The Feedback of Massive Stars on Interstellar Astrochemical Processes
Astrochemistry is a discipline that studies physico-chemical processes in astrophysical environments.
Extrasolar Planets
Spectra as Windows into Exoplanet Atmospheres
Understanding a planet's atmosphere is a necessary condition for understanding not only the planet itself, but also its formation, structure, evolution, and habitability.
Paleobiology & Biosignatures
Using Dimers to Measure Biosignatures and Atmospheric Pressure for Terrestrial Exoplanets
We present a new method to probe atmospheric pressure on Earthlike planets using (O2-O2) dimers in the near-infrared.
Panspermia
Life Could Have Hitched a Ride to Outer Planet Moons
Life on Earth or Mars could have been brought to the moons of Jupiter or Saturn on rocks blasted off those planets, researchers say.
Extrasolar Planets
Terrestrial Planet Formation at Home and Abroad
We review the state of the field of terrestrial planet formation with the goal of understanding the formation of the inner Solar System and low-mass exoplanets.
Oceanic Research
Geochemical and planetary dynamical views on the origin of Earth's atmosphere and oceans
Earth's volatile elements (H, C, and N) are essential to maintaining habitable conditions for metazoans and simpler life forms.
Habitable Zones & Global Climate
Remote Life Detection Criteria, Habitable Zone Boundaries, and the Frequency of Earthlike Planets around M and Late-K Stars
The habitable zone (HZ) around a star is typically defined as the region where a rocky planet can maintain liquid water on its surface.
Astrochemistry
Influence of Galactic Cosmic Rays on Ion-Neutral Hydrocarbon Chemistry in Upper Atmospheres of Free-Floating Exoplanets
Cosmic rays may be linked to the formation of volatiles necessary for prebiotic chemistry.
Extrasolar Planets
Feasibility Studies for the Detection of O2 in an Earth-like Exoplanet
We present the results of simulations on the detectability of O2 in the atmosphere of Earth twins around nearby low mass stars using high resolution transmission spectroscopy.
Extrasolar Planets
A Search for Methane in the Atmosphere of GJ 1214b via GTC Narrow-Band Transmission Spectrophotometry
We present narrow-band photometric measurements of the exoplanet GJ 1214b using the 10.4 m Gran Telescopio Canarias (GTC) and the OSIRIS instrument.
