We have our heads in the clouds🌤️ 🛰️This view of the Earth’s horizon as the Sun sets over the Pacific Ocean was taken by crew members aboard the International Space Station (ISS) in 2003. 🌩️ Visible in this image are the anvil tops of thunderclouds. The flat anvil tops form because when updrafts rise through the lowest layer of the atmosphere, they hit the layer above, known as the stratosphere, without penetrating it. These updrafts usually flatten wide and spread under the stratosphere, but some of them are intense enough to punch through the stratosphere. Known as overshoot tops, these can indicate where strong thunderstorms – sometimes hail or tornadoes – usually occur. ⏰Things happen fast when you’re aboard the space station! How much time does it take for the ISS to orbit the Earth? ⬇️ Give us your best guess in the comments below! ⬇️ Credit: NASA #TBT #InternationalSpaceStation #NASA #Horizon #cloudnine #atmosphere
