Ask the Space Scientist
Conducted by Dr. Sten Odenwald (Astronomer)
At this NASA website, I can no longer support questions that don't have to do with the Sun, the Earth and their various interactions. But, you may visit the Astronomy Cafe for answers to over 3000 FAQs about the Solar System, Planet-X, Stars, Galaxies, Black Holes, Big Bang Cosmology, Origin of the Universe, General and Special Relativity, Space Travel, Space Physics, Careers in Astronomy, Telescopes and many other topics, too!
All answers are provided by Dr. Sten Odenwald (Raytheon STX) for the
NASA IMAGE/POETRY Education and Public Outreach program.
