Studying these molecules
gives radio astronomers a very accurate «snapshot» of the material from which our Solar System, including Earth, was formed.
Radio waves, including the millimeter and submillimeter light that ALMA sees, are able to penetrate this dust,
giving radio astronomers a clearer picture of the dynamics and content of this hostile environment.

AUSTIN, TEXAS — A freshly reprocessed image from 27
radio telescopes has
given astronomers their largest and clearest view yet of the turbulent core of the Milky Way.
«If you have young magnetars that have just been born in supernova explosions, only a few decades old, they could be very bursty objects, have very violent youths, and that could
give rise to repeating fast
radio bursts,» says
astronomer Brian Metzger of Columbia University, who was not involved in the new study.
Without knowing these distances,
astronomers can not precisely situate any
given radio source within the galaxy to accurately reconstruct the Milky Way's morphology.
«It's really a big gift that nature has
given us,» says Alessandra Corsi, a
radio astronomer at Texas Tech University in Lubbock.
ASKAP also
gives astronomers a very large «net» with which to trawl for signals — a chunk of
radio spectrum to search through that's 300 MHz wide.
Thus were established, after World War II, the NOAO and the National
Radio Astronomy Observatory (NRAO)-- also among the first National Science Foundation (NSF) entities to be federally funded — with the aim of
giving all U.S.
astronomers access to top facilities.6 These observatories quickly adopted a so - called open skies policy (OSP), which guaranteed any researcher, U.S. or international, equal and free access to the federally funded NOAO / NRAO telescopes.
From there,
astronomers will study any electromagnetic radiation that the potential supernova is
giving off — that is, any gamma rays, x-rays, ultraviolet waves, visible light, infrared waves, microwaves and
radio waves.
Astronomers need to know how much of their astronomical data has been contaminated by
radio waves
given off by air molecules, the telescope's own electronics, and other sources of interference.
«These ALMA observations
give us new insights into how organic molecules, the building blocks of life, form and evolve in a planet - like environment,» said Anthony Remijan, an
astronomer at the National
Radio Astronomy Observatory in Charlottesville, Va., and coauthor on the paper.
