Record gamma ray burst traced to dusty massive host galaxy
Tuesday, 09 December 2025 03:08
Gamma ray bursts rank among the most energetic explosions known, usually flashing and fading within seconds or minutes, but on 2 July 2025 astronomers detected GRB 250702B, a source that produced repeated bursts for over seven hours and now stands as the longest gamma ray burst yet observed. Space based observatories, including NASAs Fermi Gamma ray Space Telescope, first recorded the gamma rays Gravitational lens time delays refine Hubble constant

Astronomers are testing a new way to measure how fast the universe is expanding by using time delays in gravitationally lensed images of distant quasars, in an effort to clarify the long-standing tension between different measurements of the Hubble constant.
The expansion rate of the universe, known as the Hubble constant, describes how quickly galaxies recede as a function of distance, wi Nova images capture complex stellar blast behavior

An international group of astronomers led by Texas Tech University assistant professor Elias Aydi published a paper titled Multiple outflows and delayed ejections revealed by early imaging of novae in Nature Astronomy on Dec. 5. The team used interferometry with the Center for High Angular Resolution Astronomy (CHARA) Array in California, combining light from multiple telescopes to obtain the hi New island of inversion found in proton neutron symmetric molybdenum nuclei

For decades, nuclear physicists have known that so called islands of inversion mark regions of the nuclear chart where standard shell structure breaks down and magic numbers vanish in favor of strongly deformed shapes. In earlier work these islands were identified mainly in neutron rich isotopes such as beryllium 12 with N = 8, magnesium 32 with N = 20, and chromium 64 with N = 40, all distant f AI advances robot navigation on the International Space Station

Imagine a robot about the size of a toaster floating through the tight corridors of the International Space Station, quietly moving supplies or checking for leaks - all without an astronaut at the controls. Such technology could free up valuable time for astronauts and open new opportunities for robotics-based exploration. That sci-fi vision is coming closer to reality now that Stanford research RISTRETTO spectrograph cleared for Proxima b atmospheric hunt

The RISTRETTO project at the University of Geneva has reached a key stage, with several core elements of its high-precision spectrograph now prototyped and tested for observations of the nearby exoplanet Proxima b. The instrument is designed to study the faint reflected light of this Earth-sized planet, which orbits Proxima Centauri at a temperature compatible with liquid water but remains outsh Pentagon weighs consolidation of DIU tech portfolio

The Minoans were a sophisticated Bronze Age civilization (c. 3100–1100 BC) on Crete and widely regarded as Europe’s earliest advanced culture. They are best known for their impressive palace complexes, most notably Knossos, and for their far-reaching maritime trade, which most likely relied on celestial navigation and a detailed understanding of the constellations. The Minoans recognised a hidden order in the natural world: a force to be respected, yet also harnessed for human benefit. Their era, the Age of Bronze, marked a pivotal moment in the development of human society.
