Molecular hydrogen is the most abundant molecule in the universe. It is the first one to form
and survive photo-dissociation in tenuous environments. Its formation involves catalytic …

Our Sun and planetary system were born about 4.5 billion years ago. How did this happen,
and what is the nature of our heritage from these early times? This review tries to address …

Water is a fundamental molecule in the universe. On Earth, water exists in all three phases:
gas, liquid, and solid (ice). Liquid water facilitates many chemical reactions as a solvent …

The cross-disciplinary field of astrochemistry exists to understand the formation, destruction,
and survival of molecules in astrophysical environments. Molecules in space are …

Since we intend to review experimental and theoretical studies of physicochemical
processes occurring on cosmic dust grains in very cold regions in space, we start with a brief …

Molecular absorption and emission bands dominate the visible, infrared, and submillimeter
spectra of most objects with associated gas. These observations reveal a surprisingly rich …

Ice mantles play a crucial role in sha** the astrochemical inventory of molecules during
star and planet formation. Small-scale molecular processes have a profound impact on large …

Quantum mechanical tunneling of atoms is increasingly found to play an important role in
many chemical transformations. Experimentally, atom tunneling can be indirectly detected …

In the denser and colder (≤ 20 K) regions of the interstellar medium (ISM), near-infrared
observations have revealed the presence of submicron-sized dust grains covered by several …

It was in 'The Magellanic Cloud'(1955)–a science fiction novel by Stanislaw Lem–that
engineers travelling to another star noticed that their spacecraft for unknown reasons …
