Astrophysicists first discovered alcohol around young stars

A group of scientists working with radio telescopes in the Chilean Observatory ALMA (Atacama Large Millimeter/submillimeter Array) for the first time in the history of the observation of the “newborn stars discovered in the protoplanetary disk of one of them, methyl alcohol, or methanol. This discovery provides a new look at chemical processes associated with star formation, the researchers said.

Protoplanetary disk, as you can guess from its name, is a disk of dense gas around a newly formed star, from which later needs to be formed of the planet. The star TW Hydra, next to which the methanol is, in the cosmic sense, very close to the Solar system at a distance of only about 170 light years from her. This is the first case of detection so complicated organic molecules in such conditions.

Because methanol is a necessary component for the emergence of more complex amino acids, its presence in the protoplanetary disk, according to scientists, to bring science to the answer to the question, how on the planet, rotating around one or another young star that could support life.

The results of their research experts presented on the pages of the scientific publication Astrophysical Journal.

Recently I learned about another very curious discovery made with a telescope ALMA. Professionals working with this telescope, failed to establish the presence of ionized oxygen in the previously discovered galaxy SXDF-NB1006-2, at a distance of 13 billion light-years from our planet. Reportedly, this discovery will allow better understanding of the history of the early Universe — in particular, to learn more about how the elements heavier than lithium, and there was a process called reionization.
