    Thank you for that, Ricardo. That was awesome… Carl was the greatest “teacher” and promoter of astronomy and astrophysics. I remember being fascinated by his documentaries at an early age. It was he who I first saw explaining the Theory of Relativity and it stuck with me. 🙂

    Thanks, once again.
