Research led by an astronomer at the Max Planck Institute for Radio Astronomy verifies the theory regarding the color of quasar accretion disks. These disks were predicted to be blue, but due to emissions from dust clouds surrounding the disk ...

Research carried out at the Max Planck Institute for Radio Astronomy has shown there has been practically no variation in the proton-electron mass ratio over the last six billion years. The research was based on studying the spectra of light ...

Many galaxies have super-massive black holes at their core, which expel powerful jets of particles at nearly the speed of light. Using the National Radio Astronomy Observatory’s very long baseline array, scientists recently confirmed the leading theory, according to which ...
