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 …
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 …
