SN 2021lwz: Understanding an Unusual Stellar Explosion Discovery and Initial Mystery On May 10, 2021, astronomers detected a supernova called SN 2021lwz at a distance of approximately 900 million light-years from Earth. What made this event remarkable was its unusual behavior: it combined characteristics of different supernova types in ways that didn't fit established classifications, prompting an in-depth investigation. Why This Supernova Matters Supernovae are among the most energetic events in the universe, marking the violent deaths of massive stars. They help astronomers understandAdvertised on -
Nuclear star clusters are dense and compact stellar systems, with sizes of a few parsecs, found at the centers of many galaxies. Their formation is thought to be closely connected to the assembly history of their host galaxies, and astronomers think that these clusters contain important clues about how galaxies formed and evolved over cosmic time. Recent studies suggest that different formation pathways may operate in late- and early-type galaxies, but the dominant mechanisms and their dependence on galaxy morphology remain unclear. While most observational studies have focused on early-typeAdvertised on -
The Instituto de Astrofísica de Canarias (IAC), through the European UNDARK project and together with CERN, has brought together international experts in cosmology, astrophysics and theoretical physics to analyse some of the discrepancies that are challenging our current understanding of the Universe. The aim is to determine whether they arise from effects in the observations that are not yet fully understood, or whether they conceal unknown physical phenomena still waiting to be discovered. We know more about the Universe than at any other time in history, and we can measure some of itsAdvertised on
