Op-Amp Challenge: Interactive Analog LED Wave Array

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, …read more Continue reading Op-Amp Challenge: Interactive Analog LED Wave Array

Astronomers witness an apocalypse from across the galaxy

Astronomers have witnessed an apocalypse from across the galaxy, as a planet crashed into its host star. It’s an event that’s long been assumed to happen in many star systems – including our own someday – but this is the first time it’s ever been seen … Continue reading Astronomers witness an apocalypse from across the galaxy

Astronomers spot nearest star-destroying black hole

Astronomers have detected a supermassive black hole ripping a passing star to shreds. Not only was this cataclysm closer to Earth than ever seen before, but its location and light emissions were unusual, hinting at a large unseen population of these ev… Continue reading Astronomers spot nearest star-destroying black hole

Intensity of stars is related to the planet-creating dust they produce

Some stars produce dust. But unlike the stuff underneath your TV cabinet, this dust plays a major part in the total luminosity of a galaxy. In a new study, scientists have used long-term observational data to see how interstellar dust correlates with a… Continue reading Intensity of stars is related to the planet-creating dust they produce

Lit-up tumors give surgeons new precision in cancer surgery

Light-guided cancer surgery has been in development for some time with varying degrees of success, from light therapy to glow-in-the-dark tumors and the development of compounds that can illuminate tumors.Continue ReadingCategory: Medical, ScienceTags:… Continue reading Lit-up tumors give surgeons new precision in cancer surgery

Pair of invisible stars found locked in tight 17-hour orbit

Astronomers have discovered a bizarre star system containing two ultra-cool dwarf stars that are so close together they orbit each other in less than a day. Oh, and they’re invisible to the human eye.Continue ReadingCategory: Space, ScienceTags: Astron… Continue reading Pair of invisible stars found locked in tight 17-hour orbit
