A total eclipse over Houston: What color was last night’s ‘blood Moon’?

I hope you saw the eclipse last night and didn’t lose too much sleep. The weather was perfect and the Moon performed as predicted. The press excitedly dubbed it a ‘blood Moon,’ but we didn’t know what color the Moon would actually be.

Here’s the Moon entering eclipse and fully in the Earth’s shadow (taken from my front yard). Is it a ‘blood Moon’ after all? You be the judge.

These photos were taken by my husband, Gary Young. (I was the frozen assistant.) We used a Takahashi FCT-76 telescope and a Canon 60D camera to capture the photos.

It was a spectacular eclipse, with Mars nearby to the right and Saturn off to the left. Both planets were very bright and easy to identify. The star near the Moon (and just off the field of these images) was Spica in the constellation Virgo.

Stay up late for a great cosmic show: The first eclipse of April 2014 is tonight!

Don’t forget: there’s a lunar eclipse tonight! The eclipse will begin shortly before midnight and continue until 4:30 in the morning on April 15. You’ll be able to see the eclipse from just about everywhere in Houston, but especially well at the George Observatory, where you can watch through telescopes away from city lights.

We’ve been getting a lot of people asking, “What exactly is a lunar eclipse?” Well, a lunar eclipse is when the Moon passes into the Earth’s shadow, or umbra. For this to happen, the Sun, Earth, and Moon have to be perfectly aligned.

For those who have never seen an eclipse, it is quite breathtaking. The Moon will start out full. As it rises, it will reach the edge of the umbra shortly before midnight, where it will begin to disappear. As the Moon continues to rise, it will slowly be engulfed by the Earth’s shadow. Then, as it sets, the Moon will slowly reappear until it is full again (roughly around 4:30 in the morning).

Since this a total eclipse, it can be viewed anywhere in the world that is facing away from the Sun. You can sit outside, even in the city, and view the eclipse yourself.

However, the George Observatory will be open all night to the public tonight. For $5 per person, you can enjoy our three large telescopes. Then, once the eclipse begins, relax on our deck and watch the eclipse with our astronomers. Besides the Moon, Mars will also be visible (we’ve just passed opposition, so tonight’s a really a great chance to see the red planet, as it’s much brighter than usual).

Want to know more about the Moon while you gaze up at it tonight? This great video from Live Science goes through the history of the formation of the Moon and how it got some of its most famous features!

The ‘blood moon’ in Houston: Stay up late at the George for a stunning celestial show

A total eclipse of the Moon will occur very early Tuesday morning, April 15. Houstonians will be able to see the whole event, which begins just before 1 a.m. You’ll be able to see the evening’s cosmic events unfold even under city lights, but if you’d like a more detailed (and dare I say captivating) look at the eclipse, the George Observatory will be open all night long!

Lunar eclipses occur when the full Moon moves into the Earth’s shadow. The first part of the Earth’s shadow that the Moon will encounter is the penumbra. The penumbral shadow’s faintness means that sharp-eyed observers will notice only a slight dimming of the Moon between 11:55 p.m. on Monday night and 12:58 a.m. Tuesday. The Moon moves into the darkest part of the earth’s shadow, the umbra, at 12:58 a.m., and will be totally eclipsed by 2:06 a.m.

The Moon’s brightness during a total eclipse depends on the amount of dust particles in the atmosphere. A large amount of dust from a volcanic eruption, for example, can make the totally eclipsed Moon almost invisible.

With little dust in our atmosphere, the Moon glows reddish-orange during totality.

This is because only the Sun’s red light comes through the Earth’s atmosphere and falls on the Moon even while it is in the Earth’s shadow. As the diagram shows, the Moon will pass through the southern part of the shadow, for about 78 minutes of totality. As a result, the northern limb, closer to the center of Earth’s shadow, will appear darker.

We’ll see our next total lunar eclipse in Houston just before dawn on October 8, 2014 (the second of four occurring between 2014 and 2015!).
