Hubble Reveals How Blue Straggler Stars Stay Young in Ancient Clusters
Astronomers using the Hubble Space Telescope have uncovered new clues to the mystery of blue straggler stars—unusually hot, bright stars found in ancient globular clusters. By studying ultraviolet light from 48 clusters, scientists discovered that blue stragglers are more common in sparse clusters, supporting the idea that they form through binar...

Scientists Discover "Iron Bar" In Space That May Reveal Earth's Future
The team said they plan to do further studies to find out what exactly this iron bar is, where it came from and what it indicates

Hypothetical ‘Dark Stars’ Could Rewrite Early Cosmic History, Research Suggests
Hypothetical dark stars could explain three early universe mysteries: the abundance of supermassive black holes, dense blue monster galaxies, and compact little red dots. Powered by dark matter rather than fusion, these stars may have formed before normal stars, collapsing to create black hole seeds and influencing early galaxy observations, accord...

A Massive Black Hole Starved Pablo’s Galaxy, Ending Its Star Formation
Astronomers using the James Webb Space Telescope and ALMA have uncovered how a massive black hole shut down star formation in Pablo’s Galaxy. Powerful winds expelled gas at hundreds of kilometres per second, leaving almost no cold fuel behind. The findings suggest many early galaxies did not die explosively, but were slowly starved by their centr...

Astronomers Find ‘Mystery Engine’ Powering Massive Nebula Around a Dead Star, Challenging Physics
Astronomers have discovered a striking shockwave around the white dwarf RXJ0528+2838, a finding that contradicts existing theories. Observed using the Very Large Telescope, the structure suggests a long-lasting outflow from a system thought to be inactive. The mystery points to an unknown energy source shaping how dead stars interact with space.

Hubble Telescope Spots Starless Dark Matter Cloud Cloud 9, Opening Window Into Dark Universe
Hubble has discovered Cloud 9, a starless dark-matter cloud near galaxy M94, offering scientists a rare chance to study early galaxy formation. This failed galaxy, part of a class known as RELHICs, shows hydrogen gas but no star formation, highlighting the role of dark matter in shaping the cosmos and revealing potential hidden structures in our lo...

Hubble Telescope Discovers Cloud-9, A New Type of Astronomical Object
Cloud-9 contains no stars, making it a unique object for studying dark matter, and the cloud is composed of neutral hydrogen gas.

Astronomers Measure Mass and Distance of a Rogue Planet for the First Time in History
Astronomers have measured the mass and distance of a rogue planet for the first time. Using observations from Earth and the Gaia space telescope, the planet was found to be just under Saturn’s mass and about 10,000 light-years away. The study highlights how free-floating planets are ejected from star systems and improves understanding of planetar...

Astronomers Look to the Large Magellanic Cloud to Study How Stars Are Born
The Large Magellanic Cloud is a nearby dwarf galaxy glowing with star birth. Just 160,000 light-years away, it hosts vast nebulae like the Tarantula and historic events such as Supernova 1987A, offering astronomers a rare, close-up laboratory to study how stars form, evolve, and explode.

Astronomers Decode the Strange Behaviour of a Young Star 1,950 Light-Years Away
Astronomers have found that the young star V1180 Cassiopeiae shows a rare mix of accretion-driven brightening and dust-caused dimming. Based on nearly 25 years of observations, the study explains its long-standing variability and shows how early stellar growth is shaped by tightly linked accretion, extinction, and outflow processes.

Planet-Eating Stars Offer a Glimpse Into Earth’s Fate as the Sun Nears Its Final Stages
Astronomers studying aging Sun-like stars have found strong evidence that stars consume their closest planets as they evolve. Using data from NASA’s TESS mission, researchers observed fewer planets around older stars, suggesting worlds are destroyed over time. The findings offer a realistic preview of Earth’s fate billions of years from now.

Interstellar Comet 3I/ATLAS Nears Earth on Dec. 19, Offering Rare Insights Into Cosmic Visitors
Interstellar comet 3I/ATLAS will make its closest approach to Earth on Dec. 19. Observing the comet provides scientists a rare opportunity to study dust and gases from its icy nucleus and learn more about material forming around other stars, expanding understanding of interstellar objects while posing no threat to our planet.

Astronomers Watch a Dormant Neutron Star Reignite After a Decade of Silence
Astronomers observed a neutron star known as P13 suddenly brighten after years of inactivity. The decade-long study shows how changes in accretion can drive extreme X-ray power, offering new insight into ultraluminous X-ray sources and neutron star physics.

Scientists Study Ancient Interstellar Comet 3I/ATLAS, Seeking Clues to Early Star System Formation
Comet 3I/ATLAS, a rare interstellar visitor from beyond the solar system, is putting on a striking celestial show as it nears Earth. After passing perihelion in October, the comet brightened nearly tenfold and shifted from red to green due to glowing carbon molecules. Tracked closely by astronomers worldwide, this ancient object offers a unique opp...

JWST Detects Thick Atmosphere on Ultra-Hot Rocky Exoplanet TOI-561 b
Astronomers using the James Webb Space Telescope have discovered compelling evidence of a thick atmosphere surrounding TOI-561 b, an ultra-hot rocky exoplanet orbiting its star every 11 hours. Despite extreme radiation and molten surface conditions, the planet appears cooler than expected, suggesting heat-redistributing atmospheric winds and volati...
