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 …
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 …
