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 …
