In fact, the Orion Nebula, NGC 1662, and the giant molecular clouds
around Lambda ([gamma]) Orionis are all roughly the same distance from the Sun.
The most recent studies on the K-S law examined the index at sub-kpc scales [14-17], closing from the intrinsic scale of star formation, that is, giant molecular clouds
size (GMCs) .
By combining these with observations from Planck, we can now obtain a link to the large-scale structures of giant molecular clouds
," remarks Timea Csengeri from the Max Planck Institute for Radio Astronomy (MPIfR), Bonn, Germany, who led the work of combining the APEX and Planck data.
The astronomers combined data collected by the Planck space telescope to cover a larger area of the Milky Way. By combining these with observations from Planck, we can now obtain a link to the large-scale structures of giant molecular clouds
," Timea Csengeri, of the Max Planck Institute for Radio Astronomy, said in a statement.
Astronomers see the signature of water in giant molecular clouds
between the stars, in disks of material that represent newborn planetary systems, and in the atmospheres of giant planets orbiting other stars.
Computational models of stars forming within galaxies commonly zoom in on giant molecular clouds
in a volume of interstellar space tens of light-years across with a resolution (ability to distinguish details) smaller than the size of our solar system.
Other trails lead from incomprehensibly (at the time) distant radio sources to the conclusion that black holes are fact, not speculation, whilst closer to home the radio signatures of complex molecules reveal the chemistry associated with Giant Molecular Clouds
formed in the death of stars.
In some regions of the Milky Way, hydrogen and other elements gravitate together to form giant molecular clouds
. One of the nearest examples is the Orion Molecular Cloud, whose dark cloak of dust and gas spans 100 light-years in southern Orion.
Papers on giant molecular clouds
include a report of the Boston University-FCRAO Galactic Ring Survey.
The researchers found signs of the amino acid in the radio-wave region of the spectra from three giant molecular clouds
