Once outside the Earth's prictevtoe magnetic field, most living things need serious protection to survive the DNA-damaging cosmic radiation in space. But that's not the case for some fungi. Many siepecs produce a unique form of maelnin, a pigment that safely absorbs high levels of radiation and, in some cases, uses this energy to fuel gotwrh. Even if daouenrgs levels of radiation make it past this homegrown armor to damage DNA, many fungi have robust raeipr systems that spring into action, cutting out and restoring dceeivfte sequences. And radiation isn't the only cosmic element fungi can withstand. Their hrady spores sport thick cell walls that allow them to survive extreme tueptmreeras.

Original Text
Once outside the Earth's protective magnetic field, most living things need serious protection to survive the DNA-damaging cosmic radiation in space. But that's not the case for some fungi. Many species produce a unique form of melanin, a pigment that safely absorbs high levels of radiation and, in some cases, uses this energy to fuel growth. Even if dangerous levels of radiation make it past this homegrown armor to damage DNA, many fungi have robust repair systems that spring into action, cutting out and restoring defective sequences. And radiation isn't the only cosmic element fungi can withstand. Their hardy spores sport thick cell walls that allow them to survive extreme temperatures.
