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

 

Don’t miss the Geminid Meteor Shower this Friday night! Here’s how, where and when to view

The annual Geminid Meteor Shower peaks this weekend, and we’ve got some tips for stargazers hoping to catch it.

The New Moon falls on Thursday, Dec. 13 this year, which should guarantee us nice, dark night for viewing. The Geminid Meteor shower peaks every December and is one of the best, most reliable showers, producing an average of 100 meteors per hour.

Says HMNS Astronomer James Wooten: “The Geminids are unique among meteor showers because they are associated not with a comet but with an asteroid, 3200 Phaethon. This means that with Geminids, we see significant activity much earlier in the night than with other showers.”

That means instead of having to wait until the wee morning hours to see this beautiful shower, meteors will start radiating from the constellation Gemini as early as 9 or 10 p.m., although the shower will likely peak just before dawn.

As with all showers, the Geminid Meteor Shower will be best viewed away from city light pollution. The George Observatory will be open Friday night and into Saturday morning for observation. For directions to The George, located just an hour south of Houston, click here. Entry to Brazos Bend State Park is $7 per person; free for kids under 12. You don’t need any special equipment for viewing, just a chair, blankets and maybe some hot apple cider.

If you observe the meteor shower and are able to capture some great photos, share them with our Flickr group or by using the hashtag #hmnsgeminid on Twitter and Instagram. If Facebook’s your thing, post your photos on our wall, or tag us, and we’ll compile a credited album of everyone’s shots!

Save the Date, Save Energy, Help Save the Planet!

Turn off your lights and unplug anything you can this Saturday night, March 28, 2009, from 8:30 to 9:30 p.m.  You’ll be joining over one billion people, in over 2,800 cities and towns in 84 countries, who have chosen to conserve energy during the international “Earth Hour” celebration.  This is the first time Houston will officially participate. 

One hour without electricity doesn’t seem like much, but if enough people turn off their lights and appliances, etc., huge amounts of energy can be saved.  Hopefully this brief participation will make all of us think a bit more about how we use (and misuse) this finite resource and will inspire us to take further actions.  For more information, visit www.earthhour.org or www.earthhourus.org

If you can see this, then you might need a Flash Player upgrade or you need to install Flash Player if it's missing. Get Flash Player from Adobe.

Then, on April 24, turn out your lights again for the 2nd annual “Lights Out Houston” program.  Although this program primarily targets Houston businesses, all of us can participate.  Last year the electricity saved was enough to power 4,600 average Texas homes for a year!  Check out http://www.houston.org/lights-out-houston/ to learn more and to see a list of businesses/corporations that participated in 2008.  If your company is not on the list, encourage the powers that be where you work to join this worthy effort! 

And be sure to get outside to gaze up at the stars during these “lights out” events!  Without all the “light pollution” of a normally-lit night in the greater Houston area, you should be able to see a lot more stars and constellations!   Lots more at www.darksky.organd www.starrynightlights.com/lpIndex.html
