Astronomers publish new sky map detecting hundreds of thousands of previously unknown galaxies
Published on 19. Februar 2019
An international team of more than 200 astronomers from 18 countries has
published the first phase of a major new radio sky survey at
unprecedented sensitivity using the Low Frequency Array (LOFAR)
telescope. The survey reveals hundreds of thousands of previously
undetected galaxies, shedding new light on many research areas including
the physics of black holes and how clusters of galaxies evolve. A
special issue of the scientific journal Astronomy & Astrophysics is
dedicated to the first twenty-six research papers describing the survey
and its first results.[Weiterlesen]

The Algae’s Third Eye
Published on 18. Februar 2019
Scientists at the Universities of Würzburg and Bielefeld in Germany have
discovered an unusual new light sensor in green algae. The sensor
triggers a reaction that is similar to one in the human eye.
Just like land plants, algae use sunlight as an energy source. Many green algae actively move in the water; they can swim to the light or move away from it. For light perception they use special sensors (photoreceptors).[Weiterlesen]
