CTAO telescope uncovers fresh evidence for layered jet structures in historic gamma ray burst
Los Angeles CA (SPX) Jul 24, 2025 The CTAO LST Collaboration has unveiled critical insights into gamma-ray burst (GRB) jets following detailed analysis of GRB 221009A-the most luminous GRB ever observed. The results, published in The Astrophysical Journal Letters, draw from 2022 observations using the LST-1, a prototype Large-Sized Telescope stationed at the Roque de los Muchachos Observatory on the CTAO-North site in La Palma, Spain. During its commissioning phase, LST-1 identified a slight excess in gamma-ray flux while monitori ... read more |

XRISM mission maps sulfur distribution across Milky WayLos Angeles CA (SPX) Jul 24, 2025 An international research team has made the first direct measurement of sulfur in both its gas and solid forms in interstellar space, using X-ray data from the Japan-led XRISM (X-ray Imaging and Spe ... more 
Astronomers discover blazing Betelgeuse has companion starParis (AFP) July 21, 2025 Since at least the time of the ancient Egyptians, people across the world have gazed up in awe at Betelgeuse, one of the brightest stars blazing in the night sky. ... more 
Nuclear timekeeping may reveal hidden traits of dark matterLondon, UK (SPX) Jul 22, 2025 For nearly a hundred years, scientists have sought dark matter, the unseen material believed to account for 80 percent of the universe's mass. Despite extensive efforts-including particle accelerato ... more 
The secret life of neutrinosSan Diego CA (SPX) Jul 22, 2025 Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun. These elementary particles come in three known "flavors": electron, muon and ... more |

Researchers claim Earth, Milky Way are trapped in cosmic voidWashington DC (UPI) Jul 10, 2025 Fresh evidence claims that the Earth and the surrounding galaxy are suspended inside a cosmic void based on echoes from the Big Bang. ... more 
Unlocking the Secrets of Cosmic Dust with the Webb TelescopeDaytona Beach, FL (SPX) Jul 09, 2025 Cosmic dust does far more than float through space. It's the raw material from which stars, planets and possibly even life emerge. Yet astronomers have long puzzled over where this vast amount of du ... more 
Dark matter fueled dark dwarfs may populate galactic coreDurham UK (SPX) Jul 09, 2025 A newly proposed class of stellar object known as a "dark dwarf" could help illuminate the elusive nature of dark matter, according to researchers from the UK and US. These theoretical bodies may be ... more 
Crystalline grains found in space ice challenge assumptions about its structureLondon, UK (SPX) Jul 08, 2025 Ice commonly found in space is not entirely amorphous, as long believed, but instead contains nanoscale crystals, according to a new study by scientists at University College London (UCL) and the Un ... more

LHAASO reveals hidden cosmic engines in high-energy Milky Way survey
Tokyo, Japan (SPX) Jul 02, 2025 China's Large High Altitude Air Shower Observatory (LHAASO) has unveiled a detailed high-energy gamma-ray map of the Milky Way, marking a milestone in the search for the origin of cosmic rays. Through its "Mini Survey of the Milky Way," LHAASO offers the most sensitive view yet of the galaxy in teraelectronvolt (TeV) to petaelectronvolt (PeV) gamma rays. Cosmic rays, high-speed charged particles from deep space, carry clues to powerful astrophysical sources like supernova remnants, pulsar wind neb ... read more 
Cosmic clocks guide SKA Observatory through commissioning phaseSydney, Australia (SPX) Jul 02, 2025 Observations of pulsars-spinning neutron stars with immense magnetic fields-are proving vital in preparing the SKA Observatory for early science operations.
