The gas mass of protoplanetary disks, and the gas-to-dust ratio, are two key elements driving the evolution of these disks and the formation of planetary system.

Carbonaceous chondrites are a class of meteorite known for having a high content of water and organics.

Our solar system, and other planetary systems, started as a disk of microscopic dust, gas, and ice around the young Sun. The amazing diversity of objects in the solar system today - the planets, moons, asteroids, and comets - was made from this primitive dust.

Astronomers have long held that water -- two hydrogen atoms and an oxygen atom -- was a relative latecomer to the universe. They believed that any element heavier than helium had to have been formed in the cores of stars and not by the Big Bang itself.

DNA is synonymous with life, but where did it originate? One way to answer this question is to try to recreate the conditions that formed DNA's molecular precursors.

Hydrocarbon organic material, as found in the interstellar medium, exists in complex mixtures of aromatic and aliphatic forms.

How soon after the Big Bang could water have existed? Not right away, because water molecules contain oxygen and oxygen had to be formed in the first stars.

Methyl acetate (CH_3COOCH_3) has been recently observed by IRAM 30 m radio telescope in Orion though the presence of its deuterated isotopomers is yet to be confirmed.

Searching for Interstellar Adenine

It is long debated if pre-biotic molecules are indeed present in the interstellar medium. Despite substantial works pointing to their existence, pre-biotic molecules are yet to be discovered with a complete confidence.

For the first time, astronomers have detected the presence of complex organic molecules, the building blocks of life, in a protoplanetary disk surrounding a young star, indicating that the conditions that spawned our Earth and Sun are not unique in the universe.
