The skies of the Canaries

The skies observe from the Canaries the most energetic pulsar light ever seen.

The emission was detected in the pulsar Crab Nebula. Researchers at the Institute of Space Studies of Catalonia (IEEC) and the Institute of Cosmos Sciences have observed the light with most energy ever seen emitted from a pulsar. The discovery was published in the journal Astronomy and Astrophysics.

The observation was carried out from the observatory MAGIC (Major Atmospheric Gammaray Imaging Cherenkov) of La Palma, where they have discovered the most energetic pulse radiation ever detected, emitted from a stellar object, the Crab pulsar.

These unexpected observations of high-energy photons question the knowledge of these tiny stars and open new challenges for particle acceleration in extreme environments.

The Crab pulsar is a tiny neutron star, about 10 kilometres in diameter, with a rotation of 30 times per second that behaves like a huge magnet and creates extremely large electric and magnetic fields around it.

It also creates a beam of light coming out of its poles and that we receive whenever its rotation crosses our line of sight, such as a lighthouse, but with energies of far greater magnitude than the visible light. The energy of this radiation is comparable to that created in the Large Hadron Collider at CERN.
