Astronomers Detect the Faint Glow of Stars in Between Galaxies

Not all stars are members of galaxies. Some stars exist in the space between galaxies, though they didn’t form there. They’re called intra-group stars, and astronomers study them by observing their light, called intra-group light (IGL.) They’re challenging to observe because their light is extremely faint and overpowered by the light of nearby galaxies. Astronomers … Read more

Encalife Lightsabers review: Push the button and let it glow

Not as clumsy or random as a blaster; an elegant weapon for a more civilized age. That’s right, we’re checking out some lightsabers today that have been sent over to use from Encalife, a company probably better known for its star projectors and telescopes, but now they’re entering the Kyber crystal game it seems. Replica … Read more

Soft devices, powered by ‘stressed’ algae, glow in the dark when squished or stretched

Nature Communications (2022). DOI: 10.1038/s41467-022-31705-6″ width=”800″ height=”530″/> Schematic of the working principle and potential applications of the biohybrid mechanoluminescence. In the light phase, the soft biohybrid robot integrated with dinoflagellate culture solution is charged with sunlight for photosynthesis to produce oxygen, providing energy for the organism. In the dark phase, the mechanically induced bioluminescence of … Read more

A surging glow in a distant galaxy could change the way we look at black holes

Physicists embark on a hunt for a long-sought quantum glow

According to a prediction known as the Unruh effect, Millenium Falcon pilots would more likely see a warm glow as they jump to hyperspace. Credit: Christine Daniloff, MIT For “Star Wars” fans, the streaking stars seen from the cockpit of the Millennium Falcon as it jumps to hyperspace is a canonical image. But what would … Read more
