Joint research led by Michiko Fujii of the University of Tokyo has unveiled a possible formation mechanism for intermediate-mass black holes (IMBHs) in globular clusters. These clusters, which can contain tens of thousands to millions of tightly packed stars, have long been suspected to host IMBHs, but direct theoretical evidence has been lacking until now. … Read more
Embarking on a journey to the edge of the universe is an awe-inspiring concept that captures the imagination and curiosity of humanity. While our current technology limits our physical exploration to the confines of our solar system, the realms beyond hold mysteries and wonders waiting to be discovered. Our journey begins on Earth, our home … Read more
A team of astronomers led by the University of Victoria and Yale University has detected an ancient star system traveling around our galaxy named Ursa Major III / UNIONS 1 (UMa3/U1)—the faintest and lowest-mass Milky Way satellite ever discovered, and possibly one of the most dark matter-dominated systems known. The team conducted the study from … Read more
Looking deep into space and time, two teams using the NASA/ESA/CSA James Webb Space Telescope have studied the exceptionally luminous galaxy GN-z11, which existed when our 13.8 billion-year-old universe was only about 430 million years old. Delivering on its promise to transform our understanding of the early universe, the James Webb Space Telescope is probing … Read more
Utilizing the powerful capabilities of NASA’s Chandra X-ray spacecraft, astronomers have conducted a thorough investigation of a potential super-star cluster, designated HSO BMHERICC J72.971176-69.391112, affectionately known as H72.97−69.39. Their recent observations have unveiled a remarkable discovery: the presence of diffuse hot gas enveloping this intriguing cluster, as detailed in a paper published on the pre-print … Read more
Astronomers have discovered one of the most powerful eruptions from a black hole ever recorded. 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. This discovery was made in the system known as SDSS J1531+3414 (SDSS J1531 … Read more
