SYDNEY, Australia — When you look up at the night sky, which constellations can you make out? Can you spot the Big Dipper? Do you see Orion’s Belt? Counting stars is pretty difficult in areas with lots of light, like major cities. A study says even in the clearest skies, you’re still seeing turbulence in the atmosphere that makes stars twinkle. Want a truly perfect view of outer space? An international research team has found the spot, but you’ll need to bundle up. It’s in Antarctica!

Stars aren’t supposed to twinkle?

According to the University of New South Wales, turbulence causes light coming from stars to bend as it reaches the Earth’s surface. That instability in the air gives stars their trademark twinkling effect.
