Easy astronomy? Deep, profound, cool stuff with no pain? That’s this weekend. On the evenings of January 26, 27, and 28, look up at the sky. The Moon will be surrounded by over a half dozen bright stars.

Of the ten first magnitude stars in the heavens, eight of them will surround the Moon.  So let’s have some fun with this. 

  • Look all around the Moon at those bright stars. First look for color. It’ll take just a few seconds to see that they’re not all white. They’re pastels. So happens, there are no green stars in the universe. But there are light blue and orange stars galore, and this weekend a bunch of those surround the Moon.
  • The colors tell tales. The bluish ones are the hottest and youngest. The orange ones are the coolest in the temperature sense.
  • You’ll notice that the star directly below the Moon, meaning the lowest down of all the stars, is also the very brightest. This blue gem is the famous Dog Star—Sirius. It also happens to be the very closest star we can ever see from the US, Europe, or Canada without a telescope.
  • The orange star to the right of the moon on Saturday is Aldebaran in Taurus the Bull.
  • The orange star to the lower right of the moon Sunday night is Betelgeuse in Orion.

But why are they all concentrated in this one area? Look around the rest of the sky and there is no other place that has such a bunch of bright stars gathered together like this.

he reason is that right behind the Moon this weekend is the nearest spiral arm of our galaxy, the Orion arm. It’s a place where there is enough free hydrogen gas that new star formation is active. The center of all this starbirth is Orion, below the Moon.

So it’s all very majestic. And lovely. And it sure takes our minds away from events in Washington. Whoops, sorry I said that.

For the next sky event, see my column on the January 31 Full Perigee Moon Eclipse—what’s being called a “Super Blue Blood Moon Eclipse.”

Thank you for this awesome info!

I enjoy this blog and always appreciate your insight. I learn so much from this blog. In regards to your comment "it sure takes our minds away from events in Washington." Don't be sorry. I agree.

I really enjoy this blog - I

I really enjoy this blog - I learn so much and get to share this knowledge with my family - a nice break away from technology to look at the night sky together.
Your statement about Washington wasn't inappropriate at all - keep doing what you're doing. If some readers get offended, they may just be insecure and petty by nature. Chill out y'all and have fun with what you're learning from Bob :)


Love your blog Bob! Thank you for continually sharing your astronomic wisdom with us.
It is treasured and appreciated. This is our universe. This is YOUR column. Say what you like. You didn't beat anybody down with an "opinion," you made a statement, a warranted one at that.
I think we can all look to the skies and take stock in the fact that no matter what, the stars will still shine.

Political statements

Leave out your political opinions. I, for one, think our current administration is doing a superb job. You said that what’s going on with the moon and stars will keep our minds off of what’s going on in Washington. Just leave out comments, like that. I enjoy all the info I get from this publication, but political opinions are not needed...
