A study by the Instituto de Astrofísica de Canarias (IAC), led by researchers Nushkia Chamba, Ignacio Trujillo and Johan H. Knapen, reveals that the enigmatic ultra-diffuse galaxies, very low-luminosity and low-density star galaxies, are similar in size to dwarf galaxies. The results, which are published in the journal Astronomy & Astrophysics, provide new clues about the number and type of galaxies in our Universe and about the nature of dark matter.

A scientific team, led by the Max Planck Institute for Quantum Optics, with participation from the Instituto de Astrofísica de Canarias, confirms the high degree of precision of the new calibration system known as a “laser frequency comb” which could be the key to the detection of planets like the Earth. The study is published in the journal Nature Astronomy.
