The eROSITA telescope has provided a new, sharp view of hot and energetic processes across the Universe. Over the course of 182 days, the eROSITA X-ray telescope onboard SRG has completed its first full sweep of the sky. This new Read More …
As most people stayed at home due to the coronavirus pandemic, we have prepared some educational presentations for children with ages below 14 to dive in-depth into astronomy topics. These series of presentations include videos, interactive games and a lot Read More …
In #AthenaNuggets 40, Jorge Sanz talks about the relationship between the emission of X-rays by a star and its exoplanets. The role of the X-rays is fundamental to understand the phenomena of erosion in exoplanet’s atmospheres. The sensitivity of Athena Read More …
Using the Wisconsin H-Alpha Mapper telescope, astronomers have for the first time measured the Fermi Bubbles in the visible light spectrum. The Fermi Bubbles are two enormous outflows of high-energy gas that emanate from the Milky Way and the finding Read More …
A new visualization, “Galactic Center VR,” features simulations of material streaming toward the Milky Way’s supermassive black hole, Sagittarius A*. Experience the last 500 years of cosmic evolution in this area in a free virtual reality program. This free program Read More …
The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed. X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number Read More …
#AthenaNuggets 42 proposes the study of quasars as new cosmic tracers. These astronomical objects will allow the measurement of the expansion rate of the Universe up to z~10, i.e., when the Universe was less than 500 million years old. The role Read More …
Ultraluminous X-ray sources (ULXs), the most extreme among binary stars, can aid us to face the following question: how many black holes managed to grow up to 10 billion Solar masses in less than a billion years after the Big Read More …
The first confirmed heartbeat of a supermassive black hole is still going strong more than ten years after first being observed. X-ray satellite observations spotted the repeated beat after its signal had been blocked by our Sun for a number Read More …
Astronomers have found a pair of objects that have been added to a strange object discovered in 2018 that combined to constitute a new class of cosmic explosions. The new type of explosion shares some of the characteristics with supernova Read More …
Half of all the calcium in the universe—including the very calcium in our teeth and bones—was created in the last gasp of dying stars. Called “calcium-rich supernovae,” these stellar explosions are so rare that astrophysicists have struggled to find and Read More …
A team from the Astronomical Observatory of the University of Valencia has managed to observe the black hole of the active galaxy PKS1830-211 right during the most violent gamma-ray energy event ever registered in that source. Scientists have discovered very Read More …
A galaxy cluster is demonstrating what can happen when a supermassive black hole stops being active. SpARCS104922.6+564032.5 (SpARCS1049 for short) is a galaxy cluster located 9.9 billion light years away from Earth. Galaxy clusters contain hundreds or thousands of galaxies Read More …
By reviving a technique capable of combining specialized gamma-ray telescopes to one giant virtual instrument, scientists have measured the diameters of individual stars hundreds of light-years away. The team used the four VERITAS telescopes (Very Energetic Radiation Imaging Telescope Array Read More …
It seems the universe has an odd sense of humor. While a crown-encrusted virus has run roughshod over the world, another entirely different corona about 100 million light years from Earth has mysteriously disappeared. For the first time, astronomers at Read More …
A team of researchers has identified a group of black holes that had previously been mistaken for a different kind of black hole, as described in the latest press release of Chandra X-ray Observatory. This discovery has important implications for Read More …
A research team led by scientists from Cardiff University says it is closer to understanding how a supermassive black hole (SMBH) was born thanks to a new technique that allowed them to zoom in on one of these. enigmatic cosmic Read More …
Astronomers have found one of the most massive black holes yet discovered, one that is gargantuan by even astronomical standards. Known as J2157, the enormous black hole weighs in at 34 billion times the mass of the Sun and is Read More …
By detecting an X-ray flare from a very young star using NASA’s Chandra X-ray Observatory, researchers have reset the timeline for when stars like the sun start blasting high-energy radiation into space, as reported in our latest press release. This Read More …
Astronomers have discovered the second-most distant quasar ever found using three Maunakea Observatories in Hawai’i: W. M. Keck Observatory, the international Gemini Observatory, a Program of NSF’s NOIRLab, and the University of Hawai’i-owned United Kingdom Infrared Telescope (UKIRT). It is Read More …
