More than 200 astronomers collaborated and using the Event Horizon Telescope (EHT) succeeded in taking the first picture of a supermassive black hole!!

ESA’s satellite, XMM-Newton, has recently discovered two giant channels of hot, X-ray emitting material flowing outwards from the Milky Way’s core into two enormous cosmic “bubbles”. These “bubbles” span about 50000 light years above and below the plane of our Galaxy Read More …

Astronomers used data from three X-ray satellites and found a black hole that spins at about 50% the speed of light!

Astronomers used X-ray data from NASA’s Chandra X-ray observatory and ESA’s XMM-Newton satellite as well as ultraviolet data from Sloan Digital Sky survey (SDSS) and found evidence that dark energy is getting stronger with time!!

Scientists used the Fermi telescope to measure the entire amount of starlight ever emitted! According to the measurement, the number of photons (particles of visible light) that escaped into space after being emitted by stars translates to 4×1084!! This is 4 followed by 84 zeros!!!

The X-ray group of IAASARS at NOA, organises a conference in Corfu, Greece, in 19-22 June 2019. The title of the conference is: “Supermassive Black Holes: Environment and Evolution”

Astronomers detected a Gamma Ray Burst (GRB) candidate that its gamma rays were not detected by our telescopes!!

Credit: ESO Astronomers detected flares of infrared radiation coming from Sagittarius A*, the massive object at the heart of our Galaxy, This observation confirms that Sagittarius A* is indeed a supermassive black hole (SMBH)!! The flares were detected using the Read More …

Many studies try to shed light on the origin of AGN obscuration. In a recent work, astronomers observed Cygnus-A, a radio galaxy about 750 million light-years from us that hosts a supermassive black hole (SMBH) which generates massive jets. These jets extent to about 150,000 light years. Their analysis reveals the presence of a strong magnetic field that regulates the feeding of the SMBH.
