Comet Encounter Previous Broadcasts

KQED 9: Wed, Jun 18, 2014 -- 10:00 PM

Comets have fascinated, even terrified us for thousands of years. Traditionally seen as harbingers of doom, they can influence some people even to this day. For scientists though, comets are a great opportunity. This year a particularly massive chunk of ice and rock is hurtling our way, an object that will fascinate billions and should create the space show of the century. Right now Comet ISON, somewhere between one and 10 kilometers in diameter, is just beyond the orbit of Jupiter. As it races past us toward the sun it should develop a tail that will light up the skies brighter than a full moon. Then the comet will slingshot around the back of the sun and could emerge brighter than ever, treating the entire northern hemisphere to an unforgettable sight. It could even be visible in daylight. Simultaneously astronomers will be able to glean vital clues on the origins of our solar system. In this program, scientists all over the world follow a once-in-a-lifetime event and shoot breath-taking images of the sun-grazer comet, spewing its essence into the void. But there is jeopardy too; the comet could evaporate completely or the sun's massive gravity could tear it apart. If the latter happens it will produce a so-called "string of pearls," several much smaller comets arching right across the night sky.

    • KQED Plus OTA ? Optimistically planned maintenance: Fri 12/05 mid-morning

      (DT54.1 thru 54.5) Assuming that the weather and road conditions permit, we plan to do a bit of maintenance on our KQEH transmitter the morning of Friday 12/05… hopefully 10am-11am-ish, but could be a bit later. Most of the work should not affect the outgoing signal, but there will need to be a cable swap […]

    • Mon 11/03/14: Work on KQED Plus tower (DT54)

      Another station needs to do maintenance on its equipment on the tower on Monument Peak, requiring that we switch our DT54 Over the Air signal from the main antenna to the auxiliary when the work starts, then back to the main antenna at the conclusion. These switches should cause momentary outages only, and most receivers […]
