XRISM uncovers a mystery in the cosmic winds of change
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed an unexpected difference between the powerful winds launching from a disc around a neutron star and those from material circling supermassive black holes. The surprisingly dense wind blowing from the stellar system challenges our understanding of how such winds form and drive change in their surroundings.

NASA begins testing PExT wideband communications system in orbit
Los Angeles CA (SPX) Sep 17, 2025
Payload commissioning has started for NASA's Polylingual Experimental Terminal (PExT), a pioneering wideband space communications technology designed to connect spacecraft with both government and commercial networks.
The demonstration rides aboard York Space Systems' Bard satellite, launched on July 23. The satellite completed its bus commissioning within four weeks, validating key system

Planet transits across starspots reveal tilted orbit in TOI-3884 system
Tokyo, Japan (SPX) Sep 17, 2025
Astronomers have mapped the architecture of the exoplanetary system TOI-3884 by capturing rare planet transits that crossed over dark starspots. Using MuSCAT3 and MuSCAT4 instruments on Las Cumbres Observatory's 2-meter telescopes, the team observed three transits in early 2024 and detected strong spot-crossing signals. The multicolor data revealed spot temperatures roughly 200 K cooler than the

Mysterious 'red dots' in early universe may be 'black hole star' atmospheres
University Park PA (SPX) Sep 17, 2025
Tiny red objects spotted by NASA's James Webb Space Telescope (JWST) are offering scientists new insights into the origins of galaxies in the universe - and may represent an entirely new class of celestial object: a black hole swallowing massive amounts of matter and spitting out light.
Using the first datasets released by the telescope in 2022, an international team of scientists includin

The 10-Point Seasonal HVAC Checklist Every Homeowner Should Follow (and Why Each Item Matters)
Los Angeles CA (SPX) Sep 17, 2025
Keeping your HVAC system healthy is one of the best ways to protect comfort, indoor air quality, and your energy bills. This seasonal 10-point checklist walks homeowners through the high-impact actions to take before heating and cooling seasons; and explains exactly why each item matters so you know which tasks you can do yourself and when to call a pro.

Reconsidering the cosmological constant
Chicago IL (SPX) Sep 17, 2025
Dark energy - the term used to describe whatever is causing the universe to expand at an increasing rate - is one of the universe's greatest mysteries. The widely accepted theory at the present moment suggests that dark energy is constant, with the energy of empty space driving cosmic acceleration. However, last year, findings from the Dark Energy Survey (DES) and Dark Energy Spectroscopic Instr

Mapping the Universe faster without sacrificing precision
Paris, France (SPX) Sep 17, 2025
Scientists face a daunting task when trying to describe the cosmic web, the immense 3D structure of galaxies, clusters, superclusters, filaments, and voids that spans the Universe. Models like the Effective Field Theory of Large-Scale Structure (EFTofLSS) combine theory and astronomical data to make statistical predictions, but they require enormous computing power.
To meet the challenge p

Alien civilizations may be far rarer than hoped study suggests
Berlin, Germany (SPX) Sep 17, 2025
New research presented at the EPSC - DPS2025 Joint Meeting in Helsinki indicates that the nearest technological civilization in the Milky Way could be about 33,000 light years from Earth, and that such a society would need to have survived at least 280,000 years - potentially millions - to coexist with us in time.
