  NASA Spots Starquakes in a Red Giant Orbiting One of the Galaxy’s Quietest Black Holes

  A red giant star orbiting a quiet black hole spins faster than expected, while internal vibrations reveal it is younger than its ancient chemistry suggests. These findings hint at a past stellar merger and challenge existing models of star evolution in low-metal environments. Future observations aim to confirm its complex cosmic history.

  ESA’s Euclid Telescope Charts Over a Million Galaxies in Landmark First Data

  ESA’s Euclid space telescope has captured about 1.2 million galaxies in its first year, providing one of the most detailed wide-field surveys of the universe ever made. Covering distances up to 10 billion light-years, Euclid’s clear, expansive imaging is helping astronomers study galaxy shapes, mergers, dwarf galaxy populations, and the role of...

  Rare ‘Second-Generation’ Black Holes Detected, Proving Einstein Right Again

  Scientists have detected two unusual black hole mergers showing signs of “second-generation” origins — meaning each large black hole likely formed from an earlier merger. The gravitational-wave signals also matched Einstein’s predictions on spinning black holes, offering fresh proof of general relativity and new insights into how black hole...

  LIGO Detect Possible Second-Generation Black Holes with Extreme Spins

  LIGO-Virgo-KAGRA observatories detected two extraordinary black hole collisions in late 2024—GW241011 and GW241110. The first involved a rapidly spinning black hole, while the second revealed one rotating opposite its orbit. These findings fit predictions for second-generation black holes, born from earlier mergers within crowded star clusters. T...

  Black Hole Tears Star Apart, Sends Out Powerful Flares Six Months Later

  Astronomers detected a black hole 650 million light-years away devouring a star and then erupting twice with powerful flares months later. Observed by the Zwicky Transient Facility and tracked by ALMA and the VLA, this rare off-centre event hints at a rogue black hole cast out from its host galaxy.

  Black Hole Kicked Away? Gravitational Waves Reveal Einstein’s Ripples in Spacetime

  Astronomers have, for the first time, measured the recoil speed and direction of a newborn black hole using gravitational waves. Data from the 2019 event GW190412 revealed the remnant shot away at 50 km/s. This breakthrough shows gravitational waves can reconstruct full 3D motion, offering new ways to connect black hole mergers with light signals.

  New Black Hole Merger Gives Clearest Test of Einstein’s Relativity

  LIGO has detected GW250114, the loudest gravitational-wave signal yet, marking ten years since its first breakthrough. The event confirmed Einstein’s relativity, Hawking’s horizon theorem, and Kerr’s spinning black hole model. By capturing the merger of two 32-solar-mass black holes, scientists gained the clearest view of black hole physics, ...

  Astronomers Discover Stellar Graveyard Filled With Black Hole and Neutron Star Collisions

  Astronomers using LIGO-Virgo-KAGRA detected 128 collisions of black holes and neutron stars, including two rare mixed mergers that double previous records. These findings reveal new details of stellar evolution, refine Hubble constant estimates, and test Einstein’s relativity in extreme conditions. The cosmic “graveyard” offers fresh insight ...

  Scientists Apply Stephen Hawking's Theory to Propose Detectable ‘Black Hole Morsels’ in Space

  A new study suggests “black hole morsels” — tiny, asteroid-sized black holes from cosmic mergers — could emit detectable bursts of Hawking radiation. Observatories like HESS, HAWC, and Fermi may already hold clues. Detecting them could unlock insights into quantum gravity, unknown particles, and even hidden dimensions beyond the Standard Mo...

  Twisted Jet Confirms Most Extreme Binary Black Hole System in the Universe

  Astronomers have confirmed that the blazar OJ 287 hosts the most extreme binary black hole system ever found. Using a global radio telescope array, they captured an ultra-sharp image showing a dramatically bent jet—evidence of two supermassive black holes locked in orbit. The system’s 12-year flare cycle and jet twists match predictions of a sm...

  JWST Finds Black Hole Between Galaxy Cores, Hinting at Rare Direct Collapse Birth

  Using JWST, astronomers discovered a black hole between two galaxy cores in the Infinity Galaxy—possibly the first direct evidence of a black hole formed by gas collapse, not stellar death. This rare “heavy seed” black hole challenges standard models and could help explain how supermassive black holes appeared so soon after the Big Bang.

  Gravitational Waves Reveal Most Massive Black Hole Merger Ever Observed

  The GW231123 event marks the most massive black hole merger ever detected through gravitational waves, involving black holes of 100 and 140 solar masses. Observed by the LIGO-Virgo-KAGRA network, it challenges current black hole formation models with extreme mass and spin, suggesting a complex origin. Scientists believe its full implications may ta...

  When Two Massive Black Holes Merged And Went Flying Across Cosmos

  The researchers propose that this ejection resulted from the collision of two galaxies, causing their central black holes to merge into a larger one.
