Largest Map of the Sky Reveals 13.7 Million HIDDEN Objects

The latest research covers 88 percent of the northern sky and includes approximately 13,000 hours of data collected over the years, providing a completely different picture of the universe. As Science Alert reports, it also includes galaxies forming strange Death Star-like shapes from supermassive black holes.

Largest Map of the Sky Reveals 13.7 Million HIDDEN Objects

TL;DR

  • The research mapped 88% of the northern sky using over 13,000 hours of data collected over a decade.
  • The LOFAR (LOw-Frequency ARray) telescope, an interferometer with 20,000 antennas across Europe, was used for the survey.
  • The project processed 18.6 petabytes of data, requiring over 20 million computer hours.
  • The resulting images provide a unique view of the universe, including galaxies with structures resembling the Death Star, likely formed by supermassive black holes.
  • LOFAR's view of the Andromeda galaxy shows radio waves generated by its central black hole and star-forming regions.
  • The data reveals how black holes shape cosmic evolution and how young stars form.
  • The processed data is now publicly available for further research.
