A white dwarf starlocated approximately 1,700 light-years away from Earthwas observed to be shrinking while continuing to steal stellar material from its companion star. Known as RX J0648.0–4418, this star is part of a unique binary system involving HD 49798, a helium-burning hot subdwarf star. The white dwarf is rapidly spinning, completing one rotation roughly … Read more
A centuries-old supernova in the constellation Cassiopeia has been illuminated by the James Webb Space Telescope (Jwst), unveiling intricate interstellar structures around 11,000 light-years away. The telescope’s infrared capabilities captured glowing gas and dust in the aftermath of the supernova’s explosion, offering astronomers a rare glimpse into the otherwise hidden dynamics of interstellar material. The … Read more
A strange and ancient supernova remnant, located roughly 6,500 light-years away from Earth, has been puzzling scientists. The remnant, known as Pa 30, surrounds a zombie star cloaked in sulfur filaments stretching across three light-years. Skywatchers first documented the explosion in 1181, but its spiky filaments and structure have only recently been studied in detail. … Read more
The mystery surrounding the Hubble tension has intensified following new findings indicating that the Coma Cluster of galaxies is 38 million light-years closer than predicted by standard cosmological models. The Hubble tension refers to a persistent discrepancy between the universe’s expansion rate as measured in the modern era and the rate predicted based on observations … Read more
T Corona Borealis is a binary star system in the Northern Crown constellation which is being monitored closely by astronomers worldwide for signs of a rare stellar eruption. The system consists of a white dwarf and a red giant orbiting each other with the white dwarf pulling material from its companion. The gradual accumulation of … Read more

A neutrino with an energy level never observed before has been detected in the depths of the Mediterranean Sea. The subatomic particlemeasuring an estimated 220 quadrillion electron volts, was recorded by a detector within the Cubic Kilometre Neutrino Telescope (KM3NeT). This discovery marks a significant milestone, as it surpasses previous neutrino detections by nearly 100 … Read more
Less than a year since Japan’s X-Ray Imaging and Spectroscopy Mission (XRISM) launched, it has delivered its first results, uncovering crucial information about black holes and supernova remnants. XRISM is a collaborative effort between the Japan Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA). Its observations have revealed the structure, movement, and temperature … Read more
Researchers unveiled a groundbreaking explanation for the mysterious zebra-like radiation pattern observed from the Crab Pulsar, a neutron star located 6,000 light-years away in the centre of the Crab Nebula. The pulsar, which emerged from a supernova recorded in 1054, has intrigued scientists with its unique high-frequency emission, distinct from other pulsars observed to date. … Read more
