Astronomers have detected a double (or a binary as it is called) star system that it is flip-flopping between two alter egos using NASA’s Chandra X-ray Observatory and the National Science Foundation’s Karl F. Jansky Very Large Array (VLA). This Read More …

An artistic view of a star tearing apart by a black hole. Image credit: NASA. Astronomers solved the mystery and found the perpetrator, an intermediate-mass black hole that was caught in action tearing apart a star that just happened to Read More …

Source: NASA / CXC / University of Cambridge / C. Reynolds et al. The “Theory of everything” is a big idea that all forces, particles and interactions in Universe connect with each other under the same framework of physics with Read More …

Scientists have detected an ancient super-massive black hole with the name PSO J030947.49+271757.31. Its distance was calculated 13 billion light-years from Earth making it officially the most distant blazar ever observed with a relativistic jet pointing directly toward Earth. The Read More …

Scientists, while studying a very distant cluster of galaxies, have discovered the biggest explosion ever seen in the Universe since the Big Bang! The energy released from this explosion is five times larger than the previous record holder, which occurred Read More …

ESA’s XMM-Newton X-ray observatory has used, for the first time, the reverberating echoes of X-ray radiation in order to map the dynamic behaviour and surroundings of a black hole (BH). This emission is the result of the infalling material into Read More …

Astronomers reported an X-ray detection of star formation in a highly magnified, strongly lensed galaxy. The system is a low-mass, low-metallicity starburst with increased X-ray emission and is an infant galaxy! Specifically, it was formed when our universe was less Read More …

Like every year, the winners of the Nobel Prize in Physics were announced for their contributions to science. The benchmark for 2019 was the broader field of Astrophysics, as Nobel shared with three scientists for their contributions to Astronomy and Read More …

One of the most important space missions was launched from the Baikonur cosmodrome on 13 July 2019 (14:31 CEST). The launch was, initially, scheduled for June 21st, however it was postponed three times due to technical issues of the “Proton Read More …

ALMA image of the disk of cool hydrogen gas flowing around Sagittarius A*. The colours represent the motion of the gas relative to Earth: the red portion is moving away and the blue colour represents gas moving toward Earth. Credit: Read More …

Astronomers have measured motions within a remarkable cosmic structure for the first time using NASA’s Chandra X-ray Observatory. The data show a blast wave and debris from an exploded star moving away from the explosion site and colliding with a Read More …

Astrophysicists have used computer simulations to show that in deep in space, tsunami-like structures may form on much bigger scales than here on Earth, from gas escaping the gravitational pull of a supermassive black hole. In fact, the mysterious environment Read More …

Published on Nature Communications the work led by Samuele Ronchini, PhD student at GSSI and INFN associate, together with INAF, which sheds new light on cooling processes happening in jets of Gamma-Ray Bursts. What are the processes that determine the Read More …

After the discovery of quasars (QSO), in the mid-1960s the X-ray astronomy started and was important to understand better the nature and the properties of the Active Galactic Nuclei (AGN), as the X-ray emission seemed to occur in the majority Read More …

A new panorama from NASA’s Chandra X-ray Observatory and the MeerKAT radio telescope provides a stunning view of the center of our Milky Way galaxy. It also reveals threads of superheated gas and magnetic fields, which are weaving a tapestry Read More …

The Athena (Advanced Telescope for High ENergy Astrophysics) mission is the second long-range space mission (L2) of the long term program “Cosmic Vision” of the European Space Agency (ESA). This mission is dedicated to the scientific theme “The hot and Read More …

Black holes are divided, based on their mass, into supermassive black holes (SMBHs) with masses more than 1 million Suns together that reside in the centre of the galaxies and stellar black holes with masses up to 20 times the Read More …
