By Leonidas Papadopoulos, on September 28th, 2015 An X-ray view (at the bottom) of the region around Sgr A*, the supermassive black hole at the center of the Milky Way galaxy, taken with NASA’s Chandra X-ray Observatory. The analysis of archival observations from Chandra and other orbiting X-ray telescopes has revealed that Sgr A* has increased its X-ray flaring by […]

An artist’s impression of a supermassive black hole. Astronomers believe that such objects lie at the centers of most galaxies in the Universe. A recent study, which was undertaken with the help of the Event Horizon Telescope, has provided new indirect evidence that indeed this is the case. Image Credit: ESO/L. Calçada

By Leonidas Papadopoulos, on May 2nd, 2015 The breathtaking image of the Hubble eXtreme Deep Field, which was created from data that had been collected with the Hubble Space Telescope in 2003 and 2004. In order for the image to be created, the space telescope pointed towards a small patch of the sky for a total of 50 days, while […]

By Leonidas Papadopoulos, on January 9th, 2015 A composite image of the area around the supermassive black hole at the center of the Milky Way, known as Sagittarius A* (Sgr A*), taken with NASA’s Chandra X-ray space telescope. The colors in the main image represent medium, and high-energy X-rays as red, green, and blue respectively. The inset box shows a […]
