A shot of the moon with a reddish hue, during a lunar eclipse.

On Wednesday, Jan. 31, early risers will have the opportunity to see a celestial trifecta: a blue supermoon coinciding with a total lunar eclipse. The moon will be closer to the earth and brighter than usual as the eclipse nears, and it will also be the second full moon of the month. Astronomer Andrew Fraknoi joins Forum to talk about this rare lunar event. He’ll also share some other exciting dispatches from the cosmos about the origin of gold in the universe, and “burping” black holes.

Guests:

Andrew Fraknoi, professor of astronomy, Osher Lifelong Learning Institute, San Francisco State University; professor emeritus, Astronomy Program, Foothill College

Rare ‘Super Blue’ Lunar Eclipse Comes Wednesday Morning 30 January,2018Michael Krasny

    Few facts about our Moon, 1) The Moon was created when a planet the size of the planet Mars collided with Earth some billions ago. 2) The Moon was formed from the debris that circled Earth After the collision 3) At it’s early history the Moon circled planet Earth at much closer distance about 20 thousands miles, less than 10% of the current distance, at that time Earth day was about 6 hours. 4) The Moon has been receding from Earth since it’s formation to it’s current distance of about 23Nefertiti8.9 thousands miles and during this process Earth day became gradually longer to it’s current value 23 hours, 56 minutes, and 4.1 seconds

    Every atom in the whole universe including those in your own body with the exception of hydrogen were made during stars life cycle, lighter elements are made in smaller stars like our Sun, atoms heavier than iron are made during the supernova explosion of stars that are much more massive than the Sun, Gold and some other heavier elements some times are made in the collision of two neutron stars………We are really made out of star dust.

      Or nuclear waste, depending how you think about it!

  • EIDALM

    Whether it is the runaway global warming, explosion of human population, as well as having reckless insane leaders across the World. I am more and more strong believer in Fermi paradox………

  • Noelle

    it’s during the wee hours of the morning, OK for nightowls, I suppose.

  • Vern

    Can the astronomer please tell us what color the moon would have been if not blue 3 billion years ago when the earth atmosphere had 10-100 times more carbon dioxide ?

  • Robert Thomas

    Our best understanding right now is that not only do we have the collision of pairs of heavy star cinders (neutron stars) to thank for our gold and platinum and uranium and so on, but also at least two elements of the periodic table absolutely required for human life,

    molybdenum (42) and
    iodine (53).

    A pretty up-to-date periodic table depicting this can be found here (courtesy Prof Jennifer Johnson, Ohio State University):

    Nothing about what time the eclipse starts … I mean, OK, I know the internet sucks compared to the radio, but to get the real scoop I’d better switch over to *AM* radio, FM’s apparently too modern and sucky … KGO here we come (I’ve actually been to the transmitter site and it’s great, 100+ years and going strong).
