JWST Spots Most Distant Supernova Ever, From 730 Million Years After Big Bang
Scientists have confirmed the most distant supernova ever observed, exploding just 730 million years after the Big Bang. Detected through a powerful gamma-ray burst and later verified by the James Webb Space Telescope, the event offers a rare glimpse of the deaths of the universe’s first stars during the era of reionisation and challenges expecta...

NASA Uses 'X-arithmetic' to Show How Black Holes Shape Galaxy Clusters
NASA's Chandra telescope has used a novel "X-arithmetic" technique to analyse X-ray data from galaxy clusters, showing how supermassive black holes influence hot gas structures and offering new insights into cosmic evolution.

X-Ray Nebula Discovery Brings Astronomers Closer to Solving Cosmic Ray Mystery
A new study has linked an unexplained LHAASO detection to a pulsar-powered X-ray nebula, confirming it as a rare PeVatron capable of accelerating particles to extreme energies. The discovery is a major step toward solving the long-standing mystery of galactic cosmic rays. Researchers are now combining X-ray, gamma-ray and neutrino observations to t...

Scientists Recreate Cosmic ‘Fireballs’ in Lab to Solve Mystery of Missing Gamma Rays
Scientists recreated cosmic plasma beams at CERN to study why certain gamma rays vanish in space. The results showed the beams remain stable, suggesting ancient intergalactic magnetic fields, not beam collapse, hide the signals. The discovery provides new insight into cosmic jets and the universe’s earliest magnetic traces.

Scientists Explore Role of Space Radiation in Powering Alien Microbial Life
A new study proposes that life may exist far from sunlight in a “radiolytic habitable zone” deep beneath the icy surfaces of Mars, Europa, and Enceladus. Cosmic rays, which can penetrate rock and ice, break water molecules apart to release hydrogen, oxygen, and energy-rich electrons. These can fuel microbes in subsurface water, much like bacter...

Scientists Recreate Cosmic Ray Physics Using Cold Atom in New Laboratory Study
Scientists have successfully recreated Fermi acceleration in a lab using ultracold atoms and movable optical barriers, simulating how cosmic rays gain energy in space. Developed by teams from Birmingham and Chicago, the mini Fermi accelerator marks a major advance in particle physics, opening doors to high-energy astrophysics studies and innovation...

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...

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 ...

The Universe’s Brightest Lights Have Surprisingly Dark and Mysterious Origins
NASA’s Fermi Gamma-ray Space Telescope has revealed that some of the universe’s brightest light sources originate near supermassive black holes in galaxy centres. These active galactic nuclei emit intense radiation, including gamma rays and X-rays, despite black holes themselves being invisible. Their powerful jets and high-energy emissions cha...

Scientists Detects Most Energetic Neutrino Ever in the Mediterranean Sea
A record-breaking neutrino with 220 quadrillion electron volts has been detected in the Mediterranean Sea. Captured by the KM3NeT deep-sea telescope, this rare cosmic event could be linked to powerful astrophysical phenomena such as black holes or supernovae. Neutrinos, nearly massless particles that rarely interact with matter, provide crucial ins...

AMS Data Reveals Charged Particle Variations in Heliosphere Over Solar Cycle
Researchers analysing AMS data aboard the ISS have identified variations in charged particles within the heliosphere over an 11-year solar cycle. Shifts in the heliospheric magnetic field impact antiproton behaviour and cosmic nuclei fluxes, revealing correlations between solar modulation and cosmic ray movement. AMS measurements provide insights i...
