PSR J0922+0638 Pulsar Keeps Glitching Every 550 Days, Scientists Are Intrigued
PSR J0922+0638, an ultradense neutron star, shows puzzling rotational glitches every 550 days. Using 22 years of radio data, scientists detected both abrupt and slow changes in its spin. These may be linked to magnetic field cycles or superfluid dynamics deep inside the star. However, the exact cause remains a mystery, demanding continued long-term...

Scientists Say Dark Matter Could Turn Failed Stars Into ‘Dark Dwarfs’
Astronomers suggest that brown dwarfs—dim, failed stars—could transform into “dark dwarfs” by capturing dark matter in their cores. When dark matter particles annihilate, they release heat, potentially lighting up these stars. Physicist Jeremy Sakstein and researchers like Jillian Paulin and Rebecca Leane support this idea, which could help...

Astronomers Capture First-Ever Image of a Dead Star That Exploded Twice in Rare Supernova Event
Astronomers have captured the first-ever image of a white dwarf star undergoing a rare double-detonation supernova. Using the Very Large Telescope, the team revealed that such explosions can occur without a star reaching the Chandrasekhar limit. The findings, published in Nature Astronomy, could reshape existing theories about stellar death and imp...

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...

NASA’s Chandra Spots Unexpectedly Strong Jet from Distant Black Hole at Cosmic Noon
NASA’s Chandra telescope has spotted two powerful black hole jets from over 11.6 billion light-years away. Detected during the universe’s cosmic noon, these jets reveal rare high-speed behaviour boosted by Big Bang remnants. The findings, which factor in relativistic effects, shed new light on early black hole growth and will be published in Th...

Astronomers Discover Most Powerful Cosmic Explosions Since the Big Bang
Astronomers have discovered extreme nuclear transients — rare and powerful explosions caused by stars being torn apart by supermassive black holes. These events, brighter and longer-lasting than supernovae, were observed using data from Gaia and ZTF. As the most energetic cosmic outbursts since the Big Bang, they offer valuable insights into blac...

3 'City-Killer' Asteroids Could Strike Earth In Weeks, Say Scientists
The study highlights the threat posed by three space rocks-named 2020 SB, 524522, and 2002 CL1-which currently share an orbit with Venus.

Quantum Tech Could Finally Let Astronomers Snap Direct Images of Earth-Like Exoplanets
Astronomers are harnessing quantum mechanics to build a coronagraph that could directly image Earth-like exoplanets previously obscured by stellar glare. By sorting light waves at the photon level, the device bypasses traditional diffraction limits, revealing faint planetary signals. This breakthrough may redefine how scientists explore distant wor...

New Study Confirms TeV Halos Are Common in Middle-Aged Pulsars
A recent study by researchers from the U.S. and Mexico using data from the HAWC Observatory has confirmed that TeV halos are a universal feature of middle-aged pulsars. These extended regions of gamma-ray emission are significantly larger than pulsar wind nebulae and may help identify otherwise undetectable pulsars. The findings challenge existing ...

New Study Sets Stronger Mass Limit on Ultralight Bosonic Dark Matter
A groundbreaking study has set a new lower bound on the mass of ultralight bosonic dark matter particles—2.2 × 10⁻²¹ eV. Using stellar motion data from the dwarf galaxy Leo II and advanced computational models, the team ruled out lighter masses that cannot form observed structures. This challenges the popular fuzzy dark matter theory and pav...

Astronomers Discover Teleios, A Supernova Remnant with Perfect Symmetry
A newly discovered supernova remnant named “Teleios,” meaning “perfect” in Greek, is astonishing scientists with its rare circular symmetry. Detected using data from ASKAP’s Evolutionary Map of the Universe, Teleios (G305.4–2.2) could be located 7,170 or 25,100 light years away. With a steep spectral index and low surface brightness, it...

Hydrogen Gas Cloud Might Help Solve the Mystery of Missing Non-Dark Matter of the Universe
Ionized Hydrogen gas cloud is believed to have the missing matter of the universe, said scientists. This discovery, conducted by DESI, changed the perspective of black hole theory and is believed to switch on and off at its duty cycle. The scientists will further use new measurements in the existing models of the Universe.

Watch: Missing Half Of Universe's Visible Matter Found Hiding In Intergalactic Space
Scientists have located the missing half of the Universe's visible matter as vast clouds of ionized hydrogen in intergalactic space, confirming it through novel techniques and survey programs showing the material is further from galactic cores than p

JWST Captures Unseen Details of Exoplanets in HR 8799 and 51 Eridani Systems
The James Webb Space Telescope (JWST) has captured groundbreaking images of exoplanets in the HR 8799 and 51 Eridani systems. By modifying its coronagraphs, astronomers allowed more starlight to pass through, revealing clearer planetary details. The study, published in The Astrophysical Journal Letters, highlights the first successful detection of ...

New Dark Matter Hypothesis Suggests Ionisation Clue in Milky Way’s Core
Researchers propose that an overlooked dark matter candidate may explain unusual ionisation levels in the Milky Way’s Central Molecular Zone (CMZ). This theory suggests that lightweight, self-annihilating dark matter particles could be producing electrons and positrons, influencing cosmic chemistry. The findings challenge conventional views, offe...
