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 …
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 …
