Unexpected Rotational Motion Detected in Ultra-Diffuse Galaxies of Hydra Cluster
Astronomers studying ultra-diffuse galaxies (UDGs) in the Hydra cluster have observed unexpected rotational movement in nearly half of the 30 galaxies examined. Spectroscopic data from the LEWIS programme, using the MUSE instrument on the Very Large Telescope, suggests that gravitational interactions with larger galaxies may influence their formati...

JWST Identifies Cooling Gas in Phoenix Cluster, Unlocking Star Formation Process
The James Webb Space Telescope has detected the missing cooling gas in the Phoenix Cluster, a galaxy cluster located 5.8 billion light-years away. Researchers used the Mid-Infrared Instrument (MIRI) to identify gas at around 540,000 degrees Fahrenheit trapped in cavities within the cluster. This discovery resolves a long-standing mystery of how sta...

Webb Telescope Unveils Hidden Process Behind Star Formation in Phoenix Cluster
NASA’s James Webb Space Telescope has uncovered the missing link in star formation within the Phoenix galaxy cluster. By mapping intermediate-temperature gas, researchers identified a crucial phase of cooling that was previously undetected. This discovery explains why the cluster’s supermassive black hole does not fully prevent star formation, ...

Gravitational Waves Reveal Black Hole Ancestry Through Spin Analysis
A study published in Physical Review Letters explores how gravitational waves reveal the ancestry of black holes. By examining 69 black hole mergers, researchers found that spin shifts indicate repeated collisions in dense star clusters. This insight supports models suggesting black holes grow through sequential mergers. Observatories like LIGO and...

Researchers Spot Unusual, Overmassive Globular Clusters in Ultra-Diffuse Galaxy FCC 224
A new study has uncovered an unexpected globular cluster system in FCC 224, an ultra-diffuse galaxy located in the Fornax cluster. Using data from the Hubble Space Telescope and the Keck Cosmic Web Imager, researchers found that FCC 224 hosts luminous, overmassive globular clusters with unusual properties. The galaxy’s star clusters exhibit narro...

Invisible Boson Stars Could Hold the Key to Dark Matter's Mysteries
Boson stars, invisible celestial objects theorised to form from axions, are now at the centre of dark matter research. Axions, light and wave-like bosons, may cluster under gravity, forming these mysterious entities. Unlike normal stars, boson stars neither emit light nor interact with regular matter in observable ways. With sizes ranging from smal...

Webb Telescope Tracks Formation and Expansion of Carbon-Rich Dust Shells in Star System
As per the latest report by NASA, the system consists of two stars in an elongated orbit. When these stars come closest, their stellar winds collide, compressing material and forming carbon-rich dust. As reported in an official press release by NASA, Emma Lieb, a doctoral student at the University of Denver and the study's lead author, noted that t...

NASA’s Hubble Observes Rare Blue Lurker Star with Unusual Evolution in M67 Cluster
NASA’s Hubble Space Telescope has identified a rare stellar phenomenon called the “blue lurker” in the M67 star cluster. Located 2,800 light-years away, this star is part of a triple-star system and has an unusual evolutionary history. The blue lurker’s accelerated spin, taking just four days, contrasts with the typical rotation of Sun-like...

Search for Elusive Missing Link Black Holes Continues as Omega Centauri Observation Turns Out to Be a Dud
The suspected intermediate-mass black hole in Omega Centauri has been reclassified as a cluster of stellar-mass black holes, according to a recent study. Unusual star movements within the dense cluster were explained using pulsar data, providing new insights into its core dynamics. This discovery reshapes theories about the elusive intermediate-mas...

New Study Challenges Presence of Intermediate-Mass Black Hole in Omega Centauri
Research published in Astronomy & Astrophysics revises earlier claims of an intermediate-mass black hole in Omega Centauri. Observed stellar velocities in the dense star cluster are now attributed to stellar-mass black holes. Pulsar data enabled scientists to refine their methods for detecting gravitational fields, offering deeper insights into the...

James Webb and Chandra Capture Images of Star Clusters in Distant Galaxies
NASA’s James Webb Space Telescope and Chandra X-ray Observatory have unveiled stunning new images of two star clusters in the Small Magellanic Cloud. NGC 602, located approximately 200,000 light-years from Earth, showcases active star formation, with dust clouds and ionised gas revealing unique stellar birth conditions. Meanwhile, NGC 2264 featur...

SpaceX Launches Two SES Communication Satellites on December 17 with Successful Recovery
On December 17, SpaceX successfully launched two communication satellites for SES, marking the second mission of the day. The O3b mPOWER 7 and 8 satellites were deployed into medium Earth orbit (MEO) approximately 5,000 miles above Earth. The Falcon 9 rocket’s first stage successfully returned to Earth after launch, landing on the Just Read the I...

Webb Telescope Confirms Planet-Forming Disks Last Longer in Early Universe
The James Webb Space Telescope has revealed that planet-forming disks around stars in the early universe lasted far longer than previously believed. By studying NGC 346, a star cluster in the Small Magellanic Cloud, Webb observed disks surviving for 20–30 million years, challenging current models. This discovery suggests that low-metal environmen...
