Twinkle-twinkle little star…
Yup, you guessed it. A star does twinkle, so one that is a
solid, unmoving light is a planet. However, planets don’t shine. Take Venus for
example. It’s commonly known as the evening star, but if you really pay
attention, Venus is just a brilliant pinpoint in the twilight. It glows and
shines like that because the sun is shining on it.
Do you know how to tell if a star is close to Earth or if
it’s going away from us?
Well, if you can’t it’s similar to the Doppler Effect (No,
not Sheldon in his Halloween costume!). A star moving away from Earth will have
a red glow about it, and a star moving toward us will have a blue tone.
If you’re a writer, watch the stars for inspiration. If
you’re a reader, just imagine the worlds out there waiting to be discovered.
Great info to know! And yes, there is so much inspiration from the sky. :)
ReplyDeleteI love watching the night sky...although one of my favorite effects is much closer to home--the Aurora Borealiis!
ReplyDeleteMy step-father is a amateur astronomer and told me that one about the red and blue stars, but I had forgotten. Thank you for the reminder. :)
