The Eagle Nebula’s Pillars of Creation contain what looks like human faces and figures. It’s not a mystery. It’s pareidolia, the same brain mechanism that sees faces on Mars and animals in clouds. Here’s the real science behind the nebula, why JWST’s 2022 images changed everything, and why the pillars may already be destroyed.
20 rivers sustaining over 2.5 billion people are in serious trouble. Dam construction, pollution, over-extraction, and climate change are killing critical freshwater systems. Data-driven breakdown by region.
A clear introduction to types of stars, stellar classification, the H-R diagram, main sequence stars, giants, white dwarfs, neutron stars, brown dwarfs, and how stars live and die.
Not all pollution glows in the dark, but radioactive pollution is uniquely dangerous. It contaminates land, water, and air with unstable atoms that emit harmful radiation for decades or centuries. I explain what radioactive pollution actually is, where it comes from, its effects on human health and ecosystems, and what we can do to prevent it.
Carl Scheele tasted hydrogen cyanide and survived. Marie Curie’s notebooks are still radioactive, stored in lead-lined boxes. Karen Wetterhahn died from a few drops of dimethylmercury through her gloves. Here are 5 chemists who paid the ultimate price for science.
