Galaxy Cluster Unveiling
The Chandra X-ray Observatory and the James Webb Space Telescope have made significant contributions to the study of galaxy clusters, unveiling hidden
cosmic activities. Through the use of X-ray mapping, Chandra exposed the invisible engines that drive these clusters. These engines, usually hidden from view, play a vital role in their formation and evolution. Simultaneously, Chandra's color-coded X-ray views provided insights into the hidden cosmic activity within galaxy clusters, offering a more nuanced understanding of these expansive structures. This has helped unveil interactions between galaxies and the impact of supermassive black holes located at their centers.
Supernova: The Oldest
The James Webb Space Telescope (JWST) has confirmed the existence of the oldest supernova ever witnessed. The supernova, linked to the gamma-ray burst GRB 250314A, offers invaluable data for understanding the universe's early stages. The detection of this event supports the idea that the universe, in its infancy, was home to frequent stellar explosions. Astronomers used the telescope to study light from the event, allowing them to determine its age and the type of star that had exploded. This discovery is a landmark finding in the study of early cosmology, offering insights into the elements created in early star formation.
Black Hole Interactions
Euclid's observations have revealed that galaxy mergers can trigger the activation of supermassive black holes. The data suggests that when galaxies collide, the resulting gravitational interactions can cause these black holes to become active, feeding on surrounding matter and releasing tremendous amounts of energy. Furthermore, scientists have observed a star's wobbling orbit around a black hole, confirming Einstein's frame-dragging theory, a prediction made over a century ago. This provides powerful evidence of how massive objects warp space-time. These findings contribute to the understanding of black hole dynamics and their influence on galaxies.
