A Search For Mid-IR Bands Of Amino Acids In The Perseus Molecular Cloud
Amino acids are building-blocks of proteins, basic constituents of all organisms and essential to life on Earth.
NASA Scientists Study Life Origins By Simulating a Cosmic Evolution
Amino acids make up millions of proteins that drive the chemical gears of life, including essential bodily functions in animals.
PHANGS-JWST First Results: Variations in PAH Fraction as a Function of ISM Phase and Metallicity
We present maps tracing the fraction of dust in the form of polycyclic aromatic hydrocarbons (PAHs) in IC 5332, NGC 628, NGC 1365, and NGC 7496 from JWST/MIRI observations.
Nanotech Away Missions: Picogram-scale Probes To Explore Nearby Stars
In a forward-looking article, George Church, PhD, from Harvard University and the Wyss Institute, proposes the use of picogram to nanogram-scale probes that can land, replicate, and produce a communications […]
PHANGS-JWST First Results: Tracing the Diffuse ISM with JWST Imaging of Polycyclic Aromatic Hydrocarbon Emission in Nearby Galaxies
JWST observations of polycyclic aromatic hydrocarbon (PAH) emission provide some of the deepest and highest resolution views of the cold interstellar medium (ISM) in nearby galaxies.
Discovery Of Interstellar NC4NH+: Dicyanopolyynes Are Indeed Abundant In Space
The previous detection of two species related to the non polar molecule cyanogen (NCCN), its protonated form (NCCNH+) and one metastable isomer (CNCN), in cold dense clouds supported the hypothesis […]
Laboratory Rotational Spectroscopy And Astronomical Search Of Ethynyl Substituted Naphthalene
The recent interstellar detection of cyanonaphthalenes bring interest in related aromatic molecular species that could be present in similar astronomical environments.
Rotational Spectra of Interstellar N- and CN-PAHs: Pyrene and Coronene
The detection of benzonitrile (C6H5CN), 1- and 2-cyano-naphthalene (C10H7CN) in the cold, dark molecular cloud TMC-1 at centimetre (cm) wavelengths has opened up prospects for the detection of other N- […]
Polyaromatic Hydrocarbons with an Imperfect Aromatic System as Catalysts of Interstellar H2 Formation
Although H2 is the simplest and the most abundant molecule in the Universe, its formation in the interstellar medium, especially in the photodissociation regions is far from being fully understood.
