Light Pollution Threatens Global Observatories, Jeopardising Deep-Sky Astronomy
Light pollution is brightening skies over observatories at an alarming rate, with artificial light growing by up to 10% each year. Astronomers caution that this glow, intensified by widespread LED use and urban expansion, is threatening the ability of telescopes to detect faint cosmic objects and diminishing humanity’s shared right to experience ...

Dark Dwarfs: New Star-Like Objects May Reveal Nature of Dark Matter
Scientists have proposed a new class of stellar objects called “dark dwarfs,” sub-stellar bodies that may glow faintly from the energy released by annihilating dark matter particles. Found near the galaxy’s core, these objects could hold crucial clues about the elusive nature of dark matter. Powered not by fusion but by WIMP-like particles, d...

Most Distant Mini-Halo Discovered in Galaxy Cluster 10 Billion Light-Years Away
Astronomers have uncovered the most distant mini-halo ever detected, located around the galaxy cluster SpARCS1049, a staggering 10 billion light-years from Earth. Using the LOFAR radio telescope network, which spans eight European countries, researchers detected a faint, diffuse glow—evidence of a giant cloud of high-energy particles and magnetic...

Scientists Discover Your Brain Secretly Glows And It Could Reveal What You're Thinking
A new study led by Canadian researchers suggests the human brain emits a faint glow that varies with activity.

Astronomers Spot Nearly Perfect Supernova Remnant of Unknown Size and Distance
Astronomers have spotted a nearly perfect spherical supernova remnant named Telios on the Milky Way’s outskirts. With its low brightness and unknown distance, Telios defies standard models of cosmic remnants and may signal a rare Type Ia supernova. Its symmetry makes it one of the most intriguing galactic remnants ever recorded.

Living Things Emit A 'Ghostly Glow' That Vanishes When We Die, Scientists Claim
The existence of this faint glow might be debatable, but scientists at the University of Calgary have come up with a study explaining the phenomenon.

Astronomers Discover Closest Known Molecular Cloud to Earth
Astronomers have discovered Eos, a massive, crescent-shaped molecular cloud only 300 light-years from Earth, making it the closest known cloud of its kind. Unlike most molecular clouds, Eos contains little carbon monoxide, which is typically used to detect such formations. Instead, it was found by tracking the faint glow of hydrogen. Shaped by cosm...

NASA Shares Images Of Uranus' Glowing Rings, "Faint And Diffuse" Feature
The very faint and diffuse Zeta ring, which is closest to the planet and appears reddish brown in the new images, is visible for the first time.

Astronomers Discover Cosmic Cloud Bigger Than Milky Way Galaxy
A team of astronomers has discovered a huge cloud of hot, faintly glowing gas in space that is bigger than the Milky Way galaxy. They said that the cosmic gas cloud, the first of its kind, may have stripped from a galaxy. What they found most surprising was that the cloud has remained clumped together for hundreds of millions of years without dissi...
