• Erratum: Detection of amino acetonitrile in Sgr B2(N) (2008, methodology): “Amino acids were successfully produced in the laboratory by UV-photolysis of ice mixtures mimicking the mantles of insterstellar grains (Bernstein et al. 2002; Muñoz Caro et al. 2002).”
• Experimental evidence for glycolaldehyde and ethylene glycol formation by surface hydrogenation of CO molecules under dense molecular cloud conditions (2015, methodology): “This discovery has motivated many of the ice chemistry studies that were performed in the following decades, with two key papers published by Bernstein et al. (2002) and Munoz-Caro, Meierhenrich & Schutte (2002).”
• Back to the Moon: The scientific rationale for resuming lunar surface exploration (2012, background): “…may be important for producing organic molecules in the icy mantles of interstellar dust grains, and on the surfaces of outer Solar System satellites and comets (e.g. Bernstein et al., 2002; Elsila et al., 2007), but the lunar poles are much more accessible than any of these other locations.”
• Increased complexity in interstellar chemistry: detection and chemical modeling of ethyl formate and n-propyl cyanide in Sagittarius B2(N) (2009, background): “…molecules are “complex” for astronomers, not for biologists! acids, as well as their racemic distributions3, uggest that they, or at least their direct precursors, have an interstellar origin (see, e.g., Ehrenfreund et al. 2001; Bernstein et al. 2002; Elsilaet al. 2007, and references therein).”
• Cometary glycine detected in samples returned by Stardust (2009, background): “Methylamine has been observed in the ISM (Ehrenfreund and Charnley 2000).”
• Complex organic molecules in protoplanetary disks (2013, background): “…glycine (and other simple amino acids) under interstellar conditions have been proposed including via Strecker synthesis (see, e.g., Peltzer et al. 1984), UV-irradiated ice mantles (see,e.g., Bernstein et al. 2002; Muñoz Caro et al. 2002), and gas-phase chemistry (see, e.g, Blagojevic et al. 2003).”
• A THREE-PHASE CHEMICAL MODEL OF HOT CORES: THE FORMATION OF GLYCINE (2013, background): “Experiments by Bernstein et al. (2002) and Muñoz Caro et al. (2002) showedthat UV irradiation of interstellar ice analogs containing H2O, CH3OH, CO, CO2, NH3 and/or HCN could produce significant quantities of amino acids, including glycine.”

• Mechanisms of Amino Acid Formation in Interstellar Ice Analogs (2007, methodology): “This observation is in agreement with previous labo ratory experiments in which amino acids have been made from several different ice compositions (Bernstein et al. 2002; Muñoz Caro et al. 2002; Holtom et al. 2005).”
• Interstellar Ice: The Infrared Space Observatory Legacy (2004, background): “…searches have focused on the gas phase (see Snyder 1997 for a review), but recent work has emphasized the possibility that they might be a minor constituent of ices that have been subjected to UV INTERSTELLAR ICE 61No. 1, 2004 photolysis (Bernstein et al. 2002; Munoz Caro et al. 2002; Woon 2002).”
• A Combined Experimental and Theoretical Study on the Formation of the Amino Acid Glycine (NH2CH2COOH) and Its Isomer (CH3NHCOOH) in Extraterrestrial Ices (2005, background): “Bernstein et al. (2002) and Ehrenfreund et al. (2001) demonstrated that, using unpolarized ultraviolet radiation of an astrophysical ice analog, the amino acids serine and alanine can be produced in a racemic mixture.”
• NON-RACEMIC AMINO ACID PRODUCTION BY ULTRAVIOLET IRRADIATION OF ACHIRAL INTERSTELLAR ICE ANALOGS WITH CIRCULARLY POLARIZED LIGHT (2011, result): “…up to 16 different amino acids has been reported in one experiment including achiral (glycine, sarcosine, β-alanine) and chiral amino acids (alanine, serine, aspartic acid, etc.; Muñoz Caro et al. 2002), and confirmed in several other similar experiments (Bernstein et al. 2002; Nuevo et al. 2008).”
• The Galactic Center: The Largest Oxygen-bearing Organic Molecule Repository (2007, background): “Several COMs, REQUENA-TORRES ET AL.358 Vol. 672 such as the simpler amino acids, can be formed in the solid phase from H2O, CH3OH, NH3, and CO or HCN ices affected by photochemistry (Dworkin et al. 2001; Bernstein et al. 2002).”
• UV-photoprocessing of interstellar ice analogs: New infrared spectroscopic results (2003, background): “Large organic compounds are produced either by ice photoprocessing (Agarwal et al. 1985; Briggs et al. 1992; Bernstein et al. 1995, 2002; Muñoz Caro et al. 2002, 2003) or by ion bombardment (e.g. Strazzulla & Baratta 1992; Kobayashi et al. 1995; Kaiser & Roessler 1998; Cottin et al. 2001).”
