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 …
Scientists with the Hard X-ray Modulation Telescope (Insight-HXMT) team has performed extensive observations of the accreting X-ray pulsar GRO J1008-57 and has discovered a magnetic field of ~1 billion Tesla on the surface of the neutron star. This is the Read More …
Astronomers have detected X-rays from Uranus for the first time, using NASA’s Chandra X-ray Observatory. This result may help scientists learn more about this enigmatic ice giant planet in our Solar System. Uranus is the seventh planet from the Sun Read More …
A new project using sonification turns astronomical images from Chandra and other telescopes into sound. As the cursor moves across the images, sounds represent the position and brightness of the sources in which each telescope plays a different instrument. Previously, Read More …
Gravitational waves are invisible (yet incredibly fast) ripples in the otherwise tough, stiff fabric of spacetime. Gravitational waves travel at the speed of light and squeeze and stretch anything in their path as they pass by. Gravitational waves are fundamentally Read More …
High-Energy Astrophysics studies astronomical objects that release electromagnetic radiation at highly energetic wavelengths that is X-rays and gamma-rays. These wavelengths come from matter with very high temperatures revealing a hot and energetic Universe! AHEAD2020 (Activities in the High Energy Astrophysics Read More …
Astronomers may have found the most distant supermassive black hole with a jet detected in X-rays using NASA’s Chandra X-ray Observatory. The source of this jet is a quasar — a rapidly growing supermassive black hole — named PSO J352.4034-15.3373 Read More …
In the first all-sky survey by the eROSITA X-ray telescope onboard SRG, astronomers at the Max Planck Institute for Extraterrestrial Physics have detected the largest in terms of apparent size supernova remnant ever observed in X-rays. The supernova remnant (SNR) Read More …
The Section of Astrophysics, Astronomy and Mechanics of the Department of Physics of the National and Kapodistrian University of Athens in Greece offers a series of virtual Colloquia in Astrophysics, every Wednesday at 6pm EET. The Spring Colloquium Sessions of Read More …
The Hellenic Astronomical Society organizes its 6th Monthly Colloquium of HelAS – 9 March 2021with invited speaker Dr. Evanthia Hatziminaoglou from the European Southern Observatory (ESO) in Germany. This event will happen on Tuesday, 9 March 2021 at 18:00 Athens Read More …
Neutron stars are the ultra dense cores of massive stars that collapse and undergo a supernova explosion. This neutron star is located within the remains of a supernova — known as 1E 0102.2-7219 (E0102 for short) — in the Small Read More …
The galaxy NGC 3079, located about 67 million light years from Earth, contains two “super-bubbles”. A pair of balloon-like regions stretch out on opposite sides of the center of the galaxy: one is 4,900 light years across and the other Read More …
