Record-Breaking Forbidden Black Hole Collision Might Finally Have an Explanation
Overview: A record-breaking cosmic collision Astronomers have announced a breakthrough in explaining the universe’s most massive black hole merger to date. In what scientists are framing as a potential solution to a long-standing paradox, two black holes once deemed “forbidden” by prevailing theories appear to have formed and merged in a way that defies previous…

Squashed Orbits Reveal Clues About Mysterious Black Hole Collision
New Clues About How Binary Black Holes Form In a landmark study, researchers are shedding light on the origins of a dramatic black hole merger detected by LIGO and Virgo, one of the few observations showing an unexpectedly squashed, or eccentric, orbital path just before the collision. The event, named GW200208_222617, offers a rare glimpse…

Squashed Orbits Reveal Likely Origins of Black Hole Collision
Unveiling a Rare Cosmic Collision A cataclysmic collision between two black holes has offered astronomers a rare glimpse into how such binaries form. Detected as GW200208_222617, the event exhibited detectable orbital eccentricity—an oval-shaped path that is less common by the time black holes merge. This finding adds a crucial clue to the long-standing question of…

Interstellar Comet 3I/ATLAS: Clues to Ancient Milky Way Origin
New clues from a long, cosmic journey Astronomers weighing the origins of the interstellar visitor 3I/ATLAS have sharpened their view of where it came from in the Milky Way. By tracing the comet’s path over the last 4.27 million years, researchers using Gaia data have built a narrative that the object might stem from the…

Black Hole Stars in Galaxy Cores: A New Cosmic Hint
What are black hole stars? A recent study by an international team of astronomers raises the provocative idea that some galaxy centers might host a rare class of objects termed “black hole stars.” In simple terms, these would be compact stellar configurations living in the extreme gravity near supermassive black holes at galactic cores. While…
