So my wife and kids are visiting the Boston area these last couple of weeks
while I'm working, and they spent the day yesterday at the Boston Science
Center. They spent some time pondering an exhibit about the anatomy of a
supernova, and stars in general.
One part of the exhibit deals with Antares and it's structure as a red
supergiant, and the fact that its physical diameter is larger than the orbit of
the inner planets.
So as we're riding home from dinner last night, my 7 year old daughter Emily is
deep in conversation with my 8 year old Mikayla about the exhibit. Emily
mentions that if Antares were our Sun, we would all burn up because the Earth
would be INSIDE the star and it's very, very hot there.
Mikayla's response: "We wouldn't burn up. It's a dry heat."
Thought this group could appreciate that in light of recent weather in Arizona.
Cheers.
Mike
