180514 KZSB SBAU radio hour 2nd Tues BaronH JW CM TW TT BM

00:00.000 music: GatoB Europa jazz saz.  Baron intros, June8 potluck, JW-dying to join right then, B-no custom calendars, so generic from ?  CM-Sky & Telescope.  TW-article S&T how detecting 1st galaxies.  B-Hubble deep field, 1 million seconds of exposure. TT-took a few months.  TW-13.4B light is so faint, so use Lyman cut-off of H, image shift of spectrum, 92.1nm UV, image above and below, since Universe expanding, you can watch the cutoff shift into the infrared.  James Webb Tele will be better.  B-light photon leaves a star, 1B stars in a galaxy, so only one star seen?  TW-no the ensemble of light from all the stars in the galaxy.  JW-Milky Way looks like cloud, light is combined.  CM-TimC says ultra deep field was 2 million seconds.  B-how stay aligned to take photo?  BM-reaction wheel torque.  CM-Hubble can point N/S without having earth in the way.  B-Hubble still op?  JW-until funding runs out or breaks.CM-should boost then pick up for Smithsonian someday.  music: summertime 1609, Galileo used telescope for very first time.

11:23.937 music: long road getting from there to here.  B-SBAU hour.  goes by fast.  Last Friday Sean Kelly gave great speech, long, had to hold questions, food would be more important.  TW-SEan talked about magnetism.  B-which is bigger mag field, ac or dc?  BM-relates to peak current  Beta/h amperes going thru coil.  B-Edison vs Telsa ac, Edison electrocute elephant to show danger of ac. JW-public did not like that demo.  BM-dc tends to throw you off.  ac field two directions.  JW-lightning transients go both directions.  B-why not spike onlyin one direction?  JW-fast videos can showthe action due to air breaking down at high voltages.  TW-when at grad student at Uof Arizona, they study that there due to monsoons in Tucson area.  Dr. Kriter's riders to see lightning events.  B-Neptune has even stronger.  TT-lightning rods?  Mark Twain story of adding more and more.  BM-cloud to cloud lightning.  CM-static on radio.  BM-ac +/- 5kHz of 1290KHz.  JW-dc current seems more of nature oddity.  electric eels....JW-evil thots.  music: i became a star of gas..

21:22.469 music:  as a space ship flies tho the endless space...stumbles onto a black hole embrace...B-TW classes finished 4 labs, 65 students.  TT-planetarium shows, 5th graders, 100k yrs across Milky Way text message.  BM-tours of Arlington theatre organ, SBTOS.org. Hal Conklin. B-take bus to Calif Sci Center w/ SBAU club in August.  TT-satellites, Imax CM-aircraft TT-rose garden. $30 bus fee. space shuttle costs.  BM-King Tut exhibit.  near USC.  B-took son to see wrestling, fake, but son loved it.  Exposition park.  B-tar pits? BM-bubbling. JW-bones, things float up.  B-outreaches?  CM-2nd Sat at Museum, etc.  TT-what in night sky?  CM-Jupiter, Venus.  Telescope workshop Broder building.  B-much done in 1.5 hrs?  JW-sure. cheering TimC on 8"  music: Gato Europa.

31:17.837  music:  Star Trek Enterprise tv show music.  B-bees in space?  BM-Beehive cluster, groups of three CM-1100 ly away.  BM-binary star stable, triple less stable over time.  B-alpha Centauri?  CM-two like sun, one red dwarf orbiting others.  B-Proxima like earth?  CM-star barf may cook planet.  JW-globular clusters, planets can be passed around.  B-about every 100yrs, get novas.  not in Globs?  CM-yes it happens, makes blue stragglers.  JW-25K yrs a star will come within 1 ly of our sun, may disturb Oort field of comets.  BM-may be more black holes in universe than stars.  TT-black hole could pass thru sun w/o us knowing.  JW-thru earth...tiny one.  Kip Thorne helped with Interstellar movie.  JW-time passes slowly in black hole field.  B-worm hole is due to black hole?  TW-often found in apples.  Music: Galileo telescope

39:46.712 music:  Gato-Europa.  B-Santa Barbara Astronomical Unit club.  2nd/4th mondays radio show.  B-Webb delayed to 2020.  CM-close pass 2am 300ft across asteroid.  mag 12.  B-gravity assist.  does that happen to passing asteroids?  CM-could be faster or slower after passing.  B-how to program a satellite to go to planets?  JW-all the physics needed to direct by Newton BM-and Kepler.  B-nudge could be way off.  BM-one ft per year over 100k yrs.  JW-course corrections can be done.  BM-thrusters.  B-Voyager 1/2 in Kuiper belt, where going? CM-Aldeberian.  B-how to get near sun?  JW-  B-solar sail?  CM-trouble expanding sails.
