Cosmic Fungi explained: The strange radiation-eating organisms found at Chernobyl

The Chernobyl tragedy was one of the most dreadful tragedies of all time. It happened when a routine test at the Chernobyl Nuclear Power Plant went horribly wrong. A massive explosion ripped through Reactor 4, spewing radioactive poison across the sky. Poison clouds drifted over Europe, forcing 1,16,000 folks from their homes overnight.

It spread global fear of nukes, redeveloped safety rules, and left a 1,000-square-mile "Exclusion Zone" that's still off-limits. Animals roam free now, but radiation lingers like a ghost. But apart from animals, some bizarre adapted creatures have also developed near the site!

Back in the late 1990s, Ukrainian scientist Nelli Zhdanova ventured into Chernobyl's toxic ruins. More than ten years after the 1986 incident that killed 31 people right away and made thousands sick, she spotted black mold surviving inside Reactor 4. Cladosporium sphaerospermum and similar fungi were growing straight toward the radiation hotspots, instead of fleeing. The darkest, melanin-packed ones were found to grow in the most dangerous spots, and it wasn’t by chance.

In 2007, Ekaterina Dadachova researched deeper, coining "radiosynthesis." This is a melanin-powered process that turns ionizing radiation, millions of times stronger than sunlight, into growth energy, like photosynthesis on steroids. According to her research, fungi don't eat isotopes but convert radiation for metabolism, growing faster in extreme doses. Aaron Berliner calls them radiotrophic, using it as nutrition.

NASA shipped Cladosporium sphaerospermum to the ISS in 2018. It grew faster in orbit's radiation bath, blocking sensors beneath it. Thicker layers shielded more, hinting at "bioshields" for astronauts. No full proof that radiation drove growth, but results showed potential.

Space radiation risks cancer and more on long missions. This mold offers passive protection, as it grows on-site, skipping pricey Earth shipments. A thin biomass layer cuts exposure. Plus, in-space farming slashes resupply needs for Moon or Mars bases.

These fungi from Chernobyl could turn into ultimate waste eaters for deep space trips. Cladosporium sphaerospermum gobbles it all, munching dead organics while thriving on space radiation. It spits out useful stuff like edible biomass or even meds. No need for heavy shipments from Earth; grow it right there on the ship.
