Would it surprise you to hear the solar eclipses repeat?
Now, I know we can’t go back in time to see past eclipses, and once the date of an eclipse—say, March 7, 1970—has passed, that date will never come again. It’s simple reality, and we’re all aware of time’s passing.
But as you’ll soon realize through these astronomy posts, astronomy is full of repeating cycles. And one of those is the saros cycle, or simply the “saros.” It’s an eclipse prediction cycle, and after every one, the same eclipse occurs again.
But how? Continue reading
There can be no doubt that solar and lunar eclipses are some of the most fascinating sights for the “naked” eye. (And I say “naked” under the assumption that you know never to look directly at the sun without approved protection!)
Unless it’s during totality. Then you can take those glasses off.
But what I mean is, solar and lunar eclipses don’t require telescopes or binoculars to be seen. You don’t need to use any special equipment. You just need your eyes, and in the case of a solar eclipse, some form of protection—like solar glasses.
You may have noticed that when a solar eclipse comes up—or even a lunar eclipse—it’s all the rage. Suddenly, the media is swamped with safety warnings and calendar countdowns to the big event.
The United States just about lost its mind over the solar eclipse of August 21, 2017. And I have a feeling the next total solar eclipse to pass over the US, in seven years, will be just as dramatic.
But you might also be wondering…how do we know when these incredible sights are going to happen? Continue reading

The total solar eclipse is an incredible phenomenon, one that I hope to see myself someday.
It isn’t often that an astronomical event occurs of such magnitude that people of all walks of life from all around the globe are drawn to one measly 65-mile wide strip of land, to crowd in like sardines as they watch the world change around them.
What’s important to realize about a total solar eclipse, versus just an annular one, is that it’s a people event.
Scientists do take this opportunity to study the sun’s corona, an outer layer of gases that’s usually too faint to be seen. But in general, this is an event for crowds to enjoy.
And enjoy it they do. I have never known another event of astronomical significance to populate the web and turn heads like a total solar eclipse.
But what happens during a solar eclipse? What can you expect to see, and how can you protect your eyes from the sun’s damaging rays? Continue reading
An annular solar eclipse is…an interesting sight, to say the least.
(I sincerely hope the photographer didn’t fry his camera taking this picture. Enough light from the sun is still reaching us to fry your retina, or damage your optics…)
The annular eclipse is not to be confused with an annual eclipse. When my dad first got excited about it back in 2012, preparing us for the spectacular sight of a solar eclipse in May, I wondered why the heck we hadn’t done this every year before.
The fact is, I’d never heard the word “annular,” so I thought Dad was just wrong.
But in reality, “annular” means something very different from “annual.” Continue reading
Have you ever heard of the blood moon?
It’s named for its red appearance. Sometimes it’s even mistaken for Mars, as in the case of the “Mars hoax” back in 2002. It was claimed then that Mars would look as large as the full moon on August 27.
In truth, Mars will never appear as large as the full moon to the naked eye (a fancy way of saying that you’re not looking through a telescope or binoculars). What really happened was that the moon passed through the Earth’s shadow.
Wait a second. The Earth has a shadow? And it’s red? Continue reading
