#atozchallenge: Pulsar

pulsar =
pulsating radio + star

 

First thing I thought of when I saw the whole thing spelled out was “Video killed the radio star”…

But seriously…

A pulsar is a rapidly-spinning neutron star (the core of a collapsed star) that beams electromagnetic radiation out along its magnetic axis. They appear to pulsate because the beam is directional and only visible when it flashes by, kind of like a lighthouse. This video from The History Channel goes into much more detail.

The Pulsar is also an auto model by Nissan.

Which do you think of when you hear “pulsar,” the star or the car?

  1. Pulsar. I think it was one of those words that I read around in the past. Made as much sense of it within the context of what I was reading and moved on. This reminds me that I ought to use the dictionary sometimes. However, it’s hard if you’re reading something really interesting to stop and look up a word…

  2. Hubby plays the Video killed the Radio Star all the time. I think it’s a funny tune personally. Love the bit of education on a pulsar too. I didn’t know that. Have a great day! hugs.
