Comet Watching for One and All

If you have a desire to look up into the night sky and watch comets go by like I do, you won't want to miss the 46P/Wirtanen comet on December 17, 2018 (when it makes its closest approach). This brilliant cosmic tourist may also be seen by the naked eye or with binoculars (this year) so everyone can try to spot it.

Check out the NASA video and description of the best hours/days and ways to view this wonderful astronomical occurrence. The next visit of the Wirtanen comet is projected to be much less impressive. So get out your coats, chairs and various gear now. Go science!

Twinkling Lights

In many countries, December is a time of twinkling lights, holiday decorations, and good cheer. Some city displays seem to challenge the night sky.

I have to admit, I love holiday lights especially the white ones. Even knowing about wavelengths, the way light travels, and all the rest of the science doesn't dim the magical feeling that a light display offers after dark.

Ever wonder how those lights would look on a large scale? A NASA-NOAA satellite gives us a much broader view of the Earth at night. Check it out.
