Galaxy cluster SDSS J1531+3414 X-ray: NASA/CXC/SAO/O. Omoruyi et al.; Optical: NASA/ESA/STScI/G. Tremblay et al.; Radio: ASTRON/LOFAR; Image Processing: NASA/CXC/SAO/N. Wolk Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded in the system known as SDSS J1531+3414 (SDSS J1531 for short). As explained in our press release, this mega-explosion billions of years ago may help explain the formation of a striking pattern of star clusters around two massive galaxies, resembling “beads on a string.” SDSS J1531 is a massive galaxy cluster containing hundreds of individual galaxies and huge reservoirs of hot gas and dark…

NeRD

January 29, 2024 / Earth Science Rahul Ramachandran (ST11) wrote his American Geophysical Union (AGU)  Leptoukh lecture as an essay titled “From petabytes to Insights: Tackling Earth Science’s Scaling Problem ”. While Ramachandran was unable to present at AGU, the essay was published on NASA EarthData website (https://www.earthdata.nasa.gov/learn/articles/2023-leptoukh-lecture-essay). The essay addresses the challenge of scaling in Earth science due to increasing data volumes. Ramachandran discusses the integration of Artificial Intelligence into informatics as a potential solution to these challenges. He reflects on his journey in informatics and emphasizes the importance of managing…

Telescopes Show the Milky Way’s Black Hole is Ready for a Kick

NeRD

NASA/CXC/M.Weiss This artist’s illustration depicts the findings of a new study about the supermassive black hole at the center of our galaxy called Sagittarius A* (abbreviated as Sgr A*). As reported in our latest press release, this result found that Sgr A* is spinning so quickly that it is warping spacetime — that is, time and the three dimensions of space — so that it can look more like a football. These results were made with NASA’s Chandra X-ray Observatory and the NSF’s Karl G. Jansky Very Large Array (VLA). A team of researchers applied a new…
