Euclid space telescope’s Near-Infrared instrument ready to draw a 3-D map of galaxies of the distant Universe
July 9, 2020
ESA’s Euclid mission to study more than a billion galaxies is a step closer to launch as its two instruments are now built and fully tested, including the complex near Near-Infrared Spectrometer and Photometer (NISP) instrument
Cosmic Cataclysm allows precise test of General Relativity
July 9, 2020
The detection of a gamma ray burst by the MAGIC telescopes allows to study whether the speed of light in vacuum is a constant of nature. The results, published in the journal Physical Review Letters, show that photons of different energies emitted about 4.5 billion years ago reach Earth with a time difference of less than one minute, thus putting a limit on the hypothesis that the velocity of photons depends on their energy.
CTA Prototype LST-1 Detects Very High-Energy Emission from the Crab Pulsar
June 22, 2020
The first prototype of the Large Size Telescope (LST) of the Cherenkov Telescope Network (CTA), the LST-1, has detected the Crab Pulsar, the neutron star at the centre of the Crab Nebula. This observation certifies the proper functioning of this telescope, which is currently in the commissioning phase.
GW190412: The merger of two black holes with unequal masses
April 12, 2020
The LIGO and Virgo Collaborations have observed gravitational waves produced by the inspiral and merger of two black holes. The signal, named GW190412, was produced by a coalescing BBH system with unequal masses, one component being more than 3 times heavier than the other one.
