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 …
For more than two decades, astronomers have been systematically tracing mystery sources of high-energy gamma rays to their sources. One, however, remained stubborn – the brightest unidentified source of gamma rays in the Milky Way. It seemed to be coming from Read More …
The covid-19 situation suspended all the visits on site, though the visits in EGO and Virgo will be LIVE BROADCASTED from the time beeing! Stay tuned! Galileo’s telescope opened the door to the stars, EGO and Virgo opened a new Read More …
A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world. The phenomenon, known as a tidal disruption event, is the Read More …
A team of gravitational wave researchers led by the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav) report that when two black holes collide and merge, the remnant black hole “chirps” not once, but multiple times, emitting gravitational waves—intense Read More …
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2020 with one half to Roger Penrose, University of Oxford, UK, “for the discovery that black hole formation is a robust prediction of the general Read More …
An analysis of archival X-ray data from NASA’s Rossi X-Ray Timing Explorer has revealed a clear separation between the characteristics of stellar-mass black holes and neutron stars, which is a consequence of the lack of the hard surface in the Read More …
The first massive galaxy groups in the Universe are predicted to have formed when the Universe was less than 4 billions years old (redshift > 2). Baryonic physics, like stellar and active galactic nuclei (AGN) feedback in this very active Read More …
A pulsar is a highly magnetized rotating compact star (usually neutron stars but also white dwarfs) that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing Read More …
In 2020, astronomers added a new member to an exclusive family of exotic objects with the discovery of a magnetar. New observations from NASA’s Chandra X-ray Observatory help support the idea that it is also a pulsar, meaning it emits Read More …
Using data from the eROSITA X-ray telescope aboard the Spektrum-Roentgen-Gamma (SRG) observatory, astronomers have detected a previously unknown supercluster of galaxies. The newly found structure consists of eight galaxy clusters. A supercluster is a large group of smaller galaxy clusters Read More …
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 …
