Astronomers used data from the Chandra observatory to find the triggering mechanism of the most recent supernova explosion in the Milky Way.

On 17th of February, the Japanese satellite Hitomi, the most sensitive X-ray telescope, was launched. On 26th of March, space debris is spotted close to the spacecraft and the communication with the satellite is lost.

Astronomers had the opportunity to capture the very first minutes of a supernova explosion and study the early moments of two dying stars.

In June 2015, the black hole V404 Cygni showed the most luminous outburst of recent years.

Astronomers used new observations from NuStar and XMM-Newton satellites to reveal the nature of a mysterious X-ray source, located in the Galactic Center region.

The project Einstein@home gives everyone the opportunity to detect a gravitational wave.

Astronomers used the Hubble Space Telescope to determine the distance of the farthest galaxy that has ever been observed. The galaxy existed only 400 million years after the Big Band, when the Dark Ages of the Universe were just ending and before the cosmic reionization era start. This means that it belongs to the very first galaxies that formed.

A recent paper by astrophysicist Avi Loeb, of the Harvard-Smithsonian Center for Astrophysics, claims that two black holes can form out of the same dying star.

Astronomers discovered an X-ray jet that was emitted from a quasar when the universe was only 2.7 billion years old, using the Chandra X-ray Observatory. The length of the jet is at least 300,000 light years.

On February 17th the X-ray satellite ASTRO-H was launched from the Tahegashima Space Centre. ASTRO-H is capable of observing with unprecedented accuracy the physical mechanisms produced by high-energy phenomena, like supernova explosions and black holes.

The X-ray XMM-Newton space telescope in October 12th, 2021 completed its 4000th orbit around the Earth with a billion kilometers travelled so far! XMM-Newton is an European Space Agency X-ray satellite launched in December 10th of 1999. The mission was 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 …
