No Intermediate-Mass Black Hole for Omega Centauri?

  From - Sky & Telescope By - Arielle Frommer Editted by - Amal Udawatta The iconic globular cluster Omega Centauri globular cluster. home to some 10 million stars. ESO / INAF-VST / OmegaCAM; Acknowledgement: A. Grado, L. Limatola / INAF-Capodimonte Observatory Last month, astronomers discovered a giant black hole in Omega Centauri. But it might contain a swarm of stellar-mass black holes instead. A new study has revealed that the Milky Way’s largest globular cluster, where astronomers recently reported the discovery of a central intermediate-mass black hole, may in fact contain thousands of stellar-mass black holes instead. Around 17,000 light-years away in the constellation Centaurus, Omega Centauri is unique among globular clusters. With its large mass and complex stellar dynamics, astronomers think it originated as an dwarf galaxy that was swallowed by the Milky Way long ago. The discovery of an  intermediate-mass black hole  (IMBH) at its center was an  exciting result , publi

'Screaming Woman' mummy suffered a painful death in ancient Egypt, virtual autopsy finds

From - Live Science By-  Kristel Tjandra Edited by - Amal Udawatta   A 3,500-year-old mummy dubbed the 'Screaming Woman' was found in an Egyptian tomb. A virtual autopsy of the mummy showed that her organs were still intact and well preserved.   (Image credit: Sahar Saleem) An ancient Egyptian woman died in so much pain, her muscles instantaneously locked up — freezing her final scream in place for 3,500 years, an analysis of the mummy, dubbed the "Screaming Woman," reveals.  The researchers also found that the woman had been embalmed in expensive imported substances and had all of her organs inside her body, suggesting a unique way of preservation. The researchers revealed their findings in a new study published Friday (Aug. 2) in the journal  Frontiers in Medicine . "Mummification in  ancient Egypt  is still full of secrets," study co-author  Sahar Saleem , a mummy radiologist at Kasr Al Ainy Hospital of Cairo University, told Live Science in an email. Int
