Each One the Size of Texas

An image of the Sun with the highest spatial resolution ever has been taken by the Daniel K Inouye Solar Telescope. Shown above is the full field image, which is displayed in false colour and shows infrared light at 789 nm wavelength.

The granular structures in the image are convection cells, which are each about the size of the US state of Texas. Hot plasma from inside the Sun bubbles up in the bright centres of the cells. It then cools by radiating its heat and falls back into the Sun in the gaps between the cells – which are dark because they are cooler.  ---  PhysicsWorld
