For radio astronomers, Earth is a noisy area. Several fashionable electronics leak radio signals, which interfere with the long, faint wavelengths of gentle researched by radio observatories. And for decades, this invisible gentle pollution has pushed radio observatories deeper into so-identified as “radio tranquil zones.” This forces radio astronomers far from other folks, out to spots like the barren Atacama Desert in Chile.
But it’s not just human-created equipment that hinder faint radio signals. Natural phenomena from Earth and the solar can interfere, way too. Introducing insult to injuries, Earth’s ionosphere — exactly where solar radiation ionizes molecules in our
