China has successfully launched a space telescope to study some of the most energetic events in the Universe. Lifting off in December 10th 2020 from the Xichang Satellite Launch Center, the Gravitational wave high-energy Electromagnetic Counterpart All-sky Monitor (GECAM, also Read More …

Some of the most stunning views of our sky occur at sunset, when sunlight pierces the clouds, creating a mixture of bright and dark rays formed by the clouds’ shadows and the beams of light scattered by the atmosphere. Astronomers Read More …

A blazar is an active galactic nucleus (AGN) with a relativistic jet (a jet composed of ionized matter traveling at nearly the speed of light) directed very nearly towards the observer. Relativistic beaming of electromagnetic radiation from the jet makes Read More …

Extraordinarily long threads of hot gas known as intergalactic filaments connect and surround galaxies and galaxy clusters throughout the cosmos — and scientists just discovered the longest one yet. The intergalactic filaments make up a cosmic web that stretches across Read More …

#AthenaNuggets 48 deals with Supermassive Black Holes (SMBHs) present in Active Galactic Nucleus (AGN). Its X-ray emission is a unique feature and enables to pierce the inner regions close to the SMBHs. Supermassive black holes are ubiquitous in the center Read More …

The first all-sky survey performed by the eROSITA X-ray telescope on-board the Spektrum-Roentgen-Gamma (SRG) observatory has revealed a large hourglass-shaped structure in the Milky Way. In particular, astronomers have spotted a pair of enormous bubbles of plasma extending above and Read More …

By studying a sample of distant galaxies, whose light comes to us from an era when the Universe was only three billion years old, a team of researchers led by Giustina Vietri of the National Institute of Astrophysics has followed Read More …

The planetarium documentary “The Hot and Energetic Universe” presents with the use of Immersive Visualizations and real images the achievements of the modern astronomy, the most advanced terrestrial and orbital observatories, the basic principles electromagnetic radiation and the natural phenomena Read More …

An international team of astronomers has conducted simultaneous radio and X-ray observations of the magnetar 1E 1547.0–5408 during its period of enhanced activity. In result, new X-ray and radio bursts were detected from this source. The finding is reported in Read More …

A new study using data from NASA’s Chandra X-ray Observatory and Hubble Space Telescope gives new insight into an important question: how habitable are planets that orbit the most common type of stars in the Galaxy? The target of the Read More …

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 …
