NASA Goes All the Way to Saturn, Takes a Stunning Selfie

That little blue dot floating in the black is every single one of us. Photo: NASA/JPL-Caltech/Space Science Institute

Last week we told you to smile wide, because a camera far, far, far away was about to take your portrait. From orbit around the gas giant Saturn, some 898 million miles from Earth, the Cassini space probe turned and took this photo. We’re that tiny blue dot, drifting in the black between Saturn’s rings and the blue smear at the bottom. (This smear, says Carolyn Porco, the head of the imaging team for Cassini, is Saturn’s E ring, a band produced by the geysers of Saturn’s moon Enceladus.)

This photo is just a sneak preview of what’s to come, says NASA. The full Saturn-Earth photo was taken as 33 individual frames, and this is just one of them. But, it’s the one that has Earth.

The snap is only humanity’s third such photo from the outer solar system. Unlike most tourists, NASA doesn’t travel to distant places just to spend the whole time taking photos of itself. One of the earlier snaps was also taken by Cassini, back in 2006. The one before that was by Voyager 1 way back in 1990—the famous Pale Blue Dot.

E.U. bans another bee-killing insecticide

This sort of bee behavior is safer in Europe than it is in America.

Bees of America, please don’t take this the wrong way, but it might be time to buzz off to Europe.

The European Union will limit the use of yet another bee-endangering insecticide, part of its efforts to protect pollinators from agricultural poisons.

The use of fipronil, a nerve agent produced by German company BASF and widely applied by farmers to kill insect pests, will be outlawed on corn and sunflower seeds and fields across Europe. From Reuters:

The restrictions take effect from Dec. 31 but seeds which have already been treated can be sown until the end of February 2014.

The ban follows similar EU curbs imposed in April on three of the world’s most widely used pesticides, known as neonicotinoids, and reflects growing concern in Europe over a recent plunge in the population of honeybees critical to crop pollination and production.

A scientific assessment from the EU’s food safety watchdog EFSA said in May that fipronil posed an “acute risk to honeybees when used as a seed treatment for maize”.

Fipronil, mainly sold under the Regent brand name in Europe, may still be used on seeds sown in greenhouses, or leeks, shallots, onions and other vegetables that are harvested before they flower, posing a low risk to foraging bees.

The U.K. and the U.S. have both been reluctant to restrict sales of pesticides that pose a threat to bees, but the U.K. is bound by the European Union’s recent bans and restrictions, while the U.S., of course, is not. Beekeepers and environmentalists in the U.S. are currently suing the EPA in an effort to institute similar bans here. From The Guardian:

Bees and other pollinators are essential in the growing of three-quarters of the world’s crops, but have seen serious declines in recent decades due to habitat loss, disease and pesticide use. In Tuesday’s vote, only the UK, Slovakia and the Czech Republic abstained and only Spain — the biggest user of fipronil — and Romania voted against. The UK was also one of eight of the 27 EU member states that unsuccessfully opposed the EC neonicotinoid ban.

“The UK abstained from the vote as there were concerns that the proposals were not based on sound scientific evidence,” said a [spokeswoman for the Department for Environment, Food and Rural Affairs]. “Fipronil is not used in any authorised pesticide in the UK so this ruling will have little impact [here].”

Paul de Zylva, of Friends of the Earth, welcomed the “leadership” of the European commission but added: “Yet again the UK’s pesticide testing regime has proven to be unfit for purpose. It’s disappointing to see the UK government abstaining from another cut and dried opportunity to protect bees.”

To the bees of America: Bon voyage.

Seeking To Save The Environment? Adhere To These Green Energy Suggestions

Making your own home more eco-friendly is a wonderful solution to help decrease your bills, whilst helping the planet. The information in this article will assist you to discover how to implement green energy solutions at your house, without the need to spend an arm and a leg on setting up.

Trees can come in handy when trying to save energy in your home. Place them in both your front and backyard when possible. This will assist to shade your home, and therefore it will not get so hot. Also, you may not have to use your air conditioning as much.

You can take full advantage of solar power without investing in high-priced installation. Focusing on window placement, insulation and landscaping will do. Clear away any trees which cast a shadow on your home, add more windows if a room is too dark and add insulation in the walls to retain the solar heat.

Start small. Even when you do not have the resources for a large-scale green energy project, you may still find things you can do. For example, solar chargers for small electronics typically only need the device to be set near a window for a few hours. Do not overlook the strength of a small initial step..

Plant trees around your home. The trees will help provide shading for you home and so will help keep your home cooler in the summer time. It will not require as much air cooling to keep it at your desired temperature. Since trees lose leaves in the winter months, they will still allow the sun to come in and help heat your home during the winter season.

Talk with your electricity company about receiving your electric power from a renewable source. Many urban centers get some of their power from hydroelectric, geothermal, solar, or wind powered plants. Typically, the electric company can merely apply a certain amount of your utility bill to renewable energy without you having to make any other changes..

If your exhaust fans are more than five years old, think about changing them with newer more efficient models. Every year you must check out each exhaust fan in your house for damage and change the filter. A damaged exhaust fan utilizes more energy and replacing the filter permits the fan to function more efficiently.

If you aren’t using something, turn it off. Any rooms in the home that are empty should not have any gadgets or lights left on. Use a power strip so that you can turn off all of your electronics at the same time, instead of letting power be wasted in standby mode.

As you can see, green energy technology isn’t so difficult to implement. Try out some of the tips you just read in your home today, so that you can begin saving energy. Not only will you be doing the earth a big favor, but you’ll save money on your electricity bills.

One more way to get greener is to purchase voluntary carbon credit. If you are not clear about voluntary carbon credit, visit the website.
