Image 1 (IMAGE) New York University Caption Artistic Impression of the Sun’s supergranules. Supergranules transport heat near the surface of the Sun and are approximately 3 times wider than the Earth. Hot material from inside the sun rises to the surface, cools and turns over before sinking back into the interior. Scientists use sound waves to see below the surface, which appear as ripples on the surface. Credit Illustration by Melissa Weiss.
