White dwarf binaries heated by intense tidal forces evolve faster than predicted
Oct 15, 2025 (SPX)
White dwarfs typically cool to about 4,000 Kelvin after billions of years, but those in short-period binaries - where two stars orbit faster than once per hour ...
Dark Matter might leave a 'fingerprint' on light, scientists say
Oct 13, 2025 (SPX)
Previously assumed to be invisible, the study, from researchers at the University of York, suggests that Dark Matter could leave faint, measurable marks on ligh...
Rice scientists use electrons to pattern light sources and wiring directly onto crystals
Oct 13, 2025 (SPX)
"The electron beam essentially works as a nanoscale pencil," said Hae Yeon Lee, an assistant professor of materials science and nanoengineering who is a corresp...
Milky Way hosts giant wave of stars revealed by Gaia
Oct 13, 2025 (SPX)
Like ripples spreading from a rock cast into water, the newly detected galactic wave shifts stars above and below the Milky Way's warped plane. The wave spans 3...
Astronomers find mystery dark object in distant universe
Oct 10, 2025 (SPX)
Because the object does not emit any light or other radiation, it was detected by the way its gravity distorts light passing through or near it-an effect called...
Astronomers detect unseen dark mass shaping distant galaxy light
Oct 10, 2025 (SPX)
"Detecting dark objects that emit no light is a formidable challenge," explained Dr. Devon Powell of the Max Planck Institute for Astrophysics (MPA) and lead au...
General purpose AI classifies transient cosmic events from just a few examples
Oct 09, 2025 (SPX)
The workflow ingests New, Reference and Difference images per candidate and outputs a real/bogus decision, a concise text rationale and an interest score for fo...
Choosing Foyer Lighting: A Guide to Illuminating Your Entryway
Oct 09, 2025 (SPX)
Start by choosing a style that suits your decor and the scale of the space. Chandeliers and pendants give presence in taller foyers, while lantern-style fixture...
Water signature detected in interstellar comet 3I ATLAS by Swift
Oct 09, 2025 (SPX)
Swift's vantage point above Earth's atmosphere enabled ultraviolet measurements that ground telescopes cannot make. The team captured the comet's faint OH glow,...
Real-time tracking of quantum uncertainty achieved using attosecond squeezed light
Oct 07, 2025 (SPX)
A team led by Dr. Mohammed Th. Hassan of the University of Arizona, with collaborators from ICFO in Spain and Ludwig-Maximilians-Universitat Munchen in Germany,...
Digital revolution brings new clarity to direct exoplanet imaging with PLACID's liquid crystal optics
Oct 07, 2025 (SPX)
Developed by researchers at the University of Bern and the University of Applied Sciences Western Switzerland in Yverdon (HEIG-VD), PLACID will join a select gr...
Cosmic constants may explain away dark matter and dark energy
Oct 06, 2025 (SPX)
Rajendra Gupta, Adjunct Professor in the Department of Physics, suggests that if the strengths of forces like gravity vary over time and across space, the resul...
Dark energy's shifting role explored through advanced supercomputer simulations
Oct 06, 2025 (SPX)
Recent findings from the Dark Energy Spectroscopic Instrument (DESI) indicate that dark energy may not be constant, suggesting a dynamic dark energy (DDE) compo...
Most powerful cosmic radio ring yet found by citizen scientists
Oct 06, 2025 (SPX)
ORCs are giant, faint rings of radio emission surrounding galaxies, visible only in radio wavelengths and composed of relativistic, magnetised plasma. First ide...
Spongy space dust reshapes understanding of star and planet formation
Oct 01, 2025 (SPX)
Professor Martin McCoustra of Heriot-Watt University, working with colleagues in Germany, Japan, the USA and Spain, helped compile decades of observational, lab...
Sharper than ever: New algorithm brings the stars into greater focus
Oct 01, 2025 (SPX)
Using algorithms that can strip away atmospheric interference, the researchers have made it possible for Earth-bound telescopes to produce some of the deepest, ...
Physicists tighten the net on elusive dark matter
Sep 30, 2025 (SPX)
"While we always hope to discover a new particle, it is important for particle physics that we are able to set bounds on what the dark matter might actually be,...
Gaia delivers first 3D fly through map of star forming regions in the Milky Way
Sep 25, 2025 (SPX)
Studying stellar birthplaces has always been challenging, since thick gas and dust obscure them from view. Gaia cannot observe these clouds directly but measure...
Rare Einstein cross with central image uncovers dark matter halo
Sep 25, 2025 (SPX)
An Einstein Cross typically forms when the gravity of foreground galaxies bends light from a background galaxy into four distinct images. The fifth central imag...
Webb maps hidden stellar nurseries in Sagittarius B2
Sep 25, 2025 (SPX)
Located a few hundred light-years from Sagittarius A*, the supermassive black hole at the galaxy's core, Sagittarius B2 contains immense reservoirs of gas and d...
