You might suggest to Dr. John to take the data to any full sky planetarium or to the Sphere in Las Vegas to display the map he creates in 3 dimensions.
Brilliant interview again Fraser, so glad you are getting these people to talk to us about the universe that helps mere mortals like me to have a better understanding of what is or might be out there.
Hello Fraser and Universe Today Team - Is it acceptable to submit a question for the Q&A show here? I understand that a white dwarf is the core of a star which has shed it's outer layer after the red giant phase. But my confusion lies in what it continues to burn. If the star had already burned all of it's fusable elements and finally carbon, what elements are allowing it to still shine? Cheers! Don Lawrence St. Croix, USVI
Stored heat. It's the exposed core that was heated to millions of degrees and is now very slowly cooling down.
