Explanation: What did the first quasars look like? The nearest quasars are now known to involve supermassive black holes in the centers of active galaxies. Gas and dust that falls toward a quasar glows brightly, sometimes outglowing the entire home galaxy. The quasars that formed in the first billion years of the universe are more mysterious, though. Featured, recent data has enabled an artist's impression of an early-universe quasar as it might have been: centered on a massive black hole, surrounded by sheets of gas and an accretion disk, and expelling a powerful jet. Quasars are among the most distant objects we see and give humanity unique information about the early and intervening universe. The oldest quasars currently known are seen at just short of redshift 8 -- only 700 million years after the Big Bang -- when the universe was only a few percent of its current age.

I bought a new little 19” b&w tv back in march 76. It had the remote ‘thumb clicker’ channel changer. Worked fine for about 2 1/2 yrs. Was married by then, and when my young wife was watching it, she was constantly checking other channels at commercial break. Soon you had to use two thumbs to make it click fast and work. I think I recall taking it apart and not being able to fix it. By fall 82 the tube was gone, and wasn’t replaced. Found out how interesting reading was all over again.
