  • Fraser Cain is one of the best astronomical journalists around. He knows enough to ask the questions that get interesting responses from scientists to us interested laypeople.

    Thank you Fraser, for giving us astronomy content during the summer!!
  • Oort cloud and interstellar comets are amazing. Nice. Give us back our 9th planet.
  • @ilkoderez601
    This was a really good interview. I learned a lot. Thank you!
  • I'm going to have to save this for tomorrow! Looking forward to it. Thank you Frasier.

    Thanks to both Frasier and Dr. David for a very educational and interesting topic.
  • @glennscott8622
    Fantastic! The “stuff” between us and Proxima is my favorite topic in astronomy.

    Given the proximity of star formation in stellar nurseries it's not unreasonable to think many stars have overlapping envelopes of influence. Frost lines be damned when we're talking about double, triple stars, stellar nurseries, supernova. Too much energy and too many wildcards. How close would oh say Alpha Centauri's double star system have to be to shed an Oumuamua sized object or even a Triton sized object. Is it possible we're swapping them now at 4 LY? Do these envelops grow exponentially with star mass or does it scale linearly?
