Surprises from Kepler's supernova

According to the latest observations of NASA's Chandra telescope, the supernova observed for the first time in 1604 by Kepler was not only more powerful, but might have also occurred at a greater distance, than previously thought. Astronomers have long studied the Kepler supernova remnant and tried to determine exactly what happened when the star exploded to create it. New analysis of a long observation from NASA's Chandra X-ray Observatory is providing more clues.

MISTRAL, a wind of change in the SRT observations

May 29, 2025

MISTRAL, a wind of change in the SRT observations MISTRAL is a new-generation receiver for observations at millimeter wavelengths, built as part of the recent project to upgrade the Sardinia Radio Telescope for the study of the high-frequency radio universe. The main features of this instrument are the very high number of detectors cooled to temperatures close to absolute zero and a dedicated cold optical system, which allow for extremely sharp images. MISTRAL made its “first light” by observing three different celestial objects: the Orion Nebula, the radio lobes of the supermassive black hole in the galaxy M87, and the supernova remnant Cassiopeia A. These images represent the first scientific observations at 90 GHz ever obtained using the SRT

Unlocking the secrets of the first Quasars: how they defy the laws of Physics to grow

Nov 20, 2024

Unlocking the secrets of the first Quasars: how they defy the laws of Physics to grow New evidence has been discovered explaining how supermassive black holes formed in the first billion years of the Universe's life. The study, conducted by INAF researchers, analyses 21 distant quasars and reveals that these objects are in a phase of extremely rapid accretion. This provides valuable insights into their formation and evolution, together with that of their host galaxies
