Astronomers Find Relic From a Galaxy That Once Consumed a Smaller One

News 18  

Astronomers at the Netherlands Research School for Astronomy have found that a globular cluster NGC 2005, a spherical collection of stars tightly bound by gravity in the Large Magellanic Cloud, a smaller neighbouring galaxy to the Milky Way, is actually a relic of the merger of a smaller galaxy into the LMC. The globular cluster, which is located some 750 light-years away from the LMC’s centre and contains about 200,000 stars, contains less silicon, zinc, calcium and copper than the other ten clusters, indicating that the cluster was not formed during the formation of the galaxy but acquired from a neighbouring smaller galaxy during a merger. During the merger, small stars of the galaxy were pulled apart and scattered while the big central globular cluster NGC 2005 survived the merger finding its new home in LMC. Our Milky Way has 150 known globular clusters which are older than open star clusters and stretch our galaxy’s age back to 13.5 billion years.

Webb captures Sombrero galaxy that hides black hole the size of 9 billion suns

India Today  

Nasa's James Webb Space Telescope has captured a stunning new image of the Sombrero galaxy, revealing unexpected details and challenging previous observations. The mid-infrared view, taken by Webb's MIRI, transforms the galaxy's appearance from its familiar hat-like shape to something resembling an archery target. In this new perspective, the Sombrero galaxy's typically bright core appears dim, unveiling a smooth inner …

Hubble uncovers cosmic collision: When a galaxy grazed the Milky Way

India Today  

In a groundbreaking discovery, NASA's Hubble Space Telescope has unveiled the remarkable survival story of the Large Magellanic Cloud, one of the Milky Way's closest galactic neighbours. This artist's concept illustrates the Large Magellanic Cloud's encounter with the Milky Way galaxy's gaseous halo. The LMC's close passage to the Milky Way has resulted in a phenomenon called ram-pressure stripping. The …

Swarm of smaller black holes found in NGC 6397 where lone, massive one was thought to exist

Firstpost  

Astronomers have discovered a concentration of smaller black holes lurking at the heart of the globular cluster NGC 6397 instead of a single massive black hole. While all globular clusters are fairly ‘old’ from an astronomical point of view, the NGC 6397 is peculiar – researchers think it may be almost as old as the universe itself. Surprisingly to the …
