Skylight: more than meets the eye

What our eyes miss in the sky – stargazing beyond the visible light spectrum

Even if you’re able to escape light pollution on a clear night, your view of the Milky Way is still obscured by the Earth’s atmosphere and, of course, limited to the visible light spectrum. Modern telescopes have transformed our understanding of the cosmos not only through their unprecedented deep-space views, but also because they’re able to detect electromagnetic frequencies outside of what we can see with our eyes, occasionally while orbiting beyond Earth’s atmosphere. This revealing video from the American Museum of Natural History guides us through celestial views at several electromagnetic frequencies, demonstrating how specialised telescopes reach beyond the visible spectrum to help demystify the observable Universe.

‘Every morning I look forward to seeing what’s in your email and there isn’t a day that goes by without reading or watching something you guys have published.

It’s like an oasis of sanity in a world gone mad.’

Jack D, USA, Friend of Aeon

‘Aeon is hands down my favourite publication to write for. Deadlines long enough to do the work justice, the best editorial input I’ve encountered and compensation which is respectful of writers’ time.’
