Photo: The clearest picture of Mercury ever taken.

 

 

  This colorful view of Mercury was produced by using images from the color base map imaging campaign during MESSENGER’s primary mission. These colors are not what Mercury would look like to the human eye, but rather the colors enhance the chemical, mineralogical, and physical differences between the rocks that make up Mercury’s surface. “

May 2013 Guide To The Five Visible Planets

 

 

Planetary trio bedecks western sky after sunset May 25.

 

” Venus and Jupiter are both now visible after sunset. Venus is buried in deep twilight in mid-May but will become more visible as the month passes. Later in May, the planet Mercury will climb up out of the glare of sunset, to appear low in the west at dusk. In the last week of May, Jupiter, Venus and Mercury will form a spectacular planetary trio. Meanwhile, Saturn – shines noticeably bright in the May 2013 evening sky all month long. And Mars is officially in the morning sky in May 2013, but not visible, having passed behind the sun from Earth last month.”

 

 

 

Planetary Alignment Peaks With Celestial Show This Weekend

 

 

 

” Venus and Jupiter, the two brightest planets in the sky this month, will be joined by tiny Mercury for a rare celestial show this weekend.

Typically, Venus, the second-closest planet to the sun, and Jupiter, which orbits beyond Mars, are tens of millions of miles apart. But they have been cycling together while moving ever closer to each other this month, joined by the innermost planet Mercury.

The celestial show peaks on Sunday when the trio will appear as a bright triangle of light in the western sky beginning about 30 minutes after sunset.

Triple conjunctions are relatively rare, according to NASA. The last one was in May 2011 and the next one will not occur until October 2015.”

 

 

 

 

 

 

 

 

Mercury Contains Water Ice At Its Poles

 ” It may be the closest planet to the Sun, but even Mercury has water ice. A lot in fact—as much as 100 billion to 1 trillion tons, according to a trio of studies published today by scientists working with NASA’s MESSENGER orbiter. The findings, out today in the journal Science, are the first to give strong evidence of water in Mercury’s polar regions, following decades of speculation. “

What You Need To Know About The Lightbulb Law

 

 

 

 

Here Is Popular Mechanics Fawning Take On The Subject … 

 

 

 ” These changes in the law are going to demand that we change the way we think about lightbulbs. We’re accustomed to a lightbulb being a minor expense, but the upfront cost of an energy-efficient one is much higher. Some might cost $30 or more per bulb.

CFLs represent the best value for consumers, as they use one-fourth the power of a comparable incandescent lightbulb and last up to 10 times longer. As a result, each CFL will save the consumer at least $30 in the form of lower electricity costs over the life of the bulb. ”

 

But There Is More To CFLs Than Energy Savings …

 

 

 

 

Are Compact Fluorescent Lightbulbs Dangerous?

 

” Compact fluorescent lightbulbs contain a minuscule amount of mercury, and you can’t safely ignore potential contact with it .

Lightbulbs break all the time. So why would a single broken bulb in a Maine household trigger the state’s Department of Environmental Protection to refer the homeowner to a decontaminator?

The answer lies in the type of bulb that broke—a compact fluorescent lightbulb—and what was inside that bulb. Compact fluorescents, like their tubular fluorescent precursors, contain a small amount of mercury—typically around five milligrams. Mercury is essential to a fluorescent bulb’s ability to emit light; no other element has proved as efficient.

As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children. That’s why officials have curtailed or banned its use in applications from thermometers to automotive and thermostat switches. ”
