Don’t fight the dark: Five simple ways to cut down on light pollution

When you visit the George Observatory, you’ll notice signs that say, “Please no white lights.” You’ll also see that all our outside lights are red. The reason we do this is to fight light pollution and create a dark-sky-friendly environment (or at least as dark as we can this close to Houston). 

Despite our best efforts, the surrounding area is slowly losing its dark skies. This is unfortunate, and not just for those of us who love to stargaze. Too much light at night is also bad for animal migrations, human sleep patterns, and even personal safety.

So what can we, as individuals, do to fight light pollution?  Here are five simple things:

1. Turn off all unused lights
Your dad was right: leaving lights on when you’re not using them is just throwing money away. So when you leave an area, make it a habit to turn the lights off.

2. Shield all outside lights
Outside lights should serve one purpose: to show you where you’re going. So why do so many people insist on lighting the underside of passing airplanes? We encourage you to invest in light shields. They will help with light pollution and save you money.

3. Don’t over-light
When installing outside fixtures, consider the best wattage for your needs. You want enough light to see where you are going — anything else isn’t helping you see . Also, your neighbors will appreciate you not flooding their bedrooms with light.

4. Avoid ornamental lighting
It’s wonderful that you’re proud of your home, but remember what we said about light pollution and crime. When you overuse ornamental light, you may feel like your house is more secure; however, you’re actually making your property a target for thieves.

5. Spread the word!
Now that you know the dangers of light pollutions, share that information with others. There are many websites that will help you and your friends protect the night sky, like the International Dark Sky Association.

Knowledge is power, and we all need to do our part to keep the stars at night big and bright deep in the heart of Texas!

To see the best dark skies in the Houston area come out to the George Observatory! From there you can see stars, galaxies planets… almost anything in space. And what’s more, we want to help you see everything out there better, so bring your telescope out for our telescope classes. The next one’s coming up this Saturday, May 3 from 5 p.m. to 7 p.m

 

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!
