Springtime for Toxics

Springtime for Toxics

          Springtime for Toxics By Paul Krugman Here’s what I wanted for Christmas: something that would make us both healthier and richer. And since I was just making a wish, why not ask that Americans get smarter, too? Surprise: I got my wish, in the form of new Environmental Protection Agency standards on mercury and air toxics for power plants. These rules are long overdue: we were supposed to start regulating mercury more than 20 years ... Full Story

Sky Tonight—May 6, Mercury at greatest morning elongation May 7

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org Mercury, the solar system’s innermost planet, reaches its greatest western elongation from the sun on Saturday, May 7. Because Mercury is farthest west of the sun at present, this world now rises into the morning sky before sunrise – but how much before depends on where you live on the globe. The farther north you live, the closer Mercury rises to sunrise. The farther south you live, the greater the ... Full Story

MESSENGER at Mercury Credit: NASA/JHU APL/CIW Explanation: On March 17, the MESSENGER spacecraft became the first to orbit Mercury, the solar system's innermost planet. This is its first processed color image since entering Mercury orbit. Larger, denser, and with almost twice the surface gravity of Earth's moon, Mercury still looks moon-like at first glance. But in this view its terrain shows light blue and brown areas near craters and long bright rays of material streaking the ... Full Story

Sky Tonight—Tuesday, March 22, Mercury farthest from sunset glare

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org Mercury, the solar system’s innermost planet, never strays far from the sun and into Earth’s nighttime sky. Today, however, this world reaches its greatest elongation east of the sun at 7 p.m. Mountain Daylight Time. Mercury swings to the end of its tether, at 19 degrees east of the sun. (For reference, your fist at an arm’s length approximates 10 degrees of sky.) Nineteen degrees east of the sun is ... Full Story

Sky Tonight—March 21, As Mercury sets, zodiacal light shines faintly in western sky

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org After the sun sets, you can see the elusive planet Mercury – and the even more elusive zodiacal light – in the western sky. For those living in the northern hemisphere, this next week presents the best chance in all of 2011 to see Mercury, the solar system’s innermost planet. Meanwhile, if you have a very dark sky, the zodiacal light can be seen in the west about an hour after sunset through March and ... Full Story

CU-Boulder space scientists ready for orbital

  NASA’s MESSENGER mission, launched in 2004, is slated to slide into Mercury’s orbit March 17 after a harrowing 4.7 billion mile journey that involved 15 loops around the sun and will bring relief and renewed excitement to the University of Colorado Boulder team that designed and a built an $8.7 million instrument onboard. “In 2004, this milestone seemed like it was a long, long way away,” said Senior Research Associate William McClintock, a mission co-investigator from ...

Sky Tonight—March 16, Smallest and largest planets in conjunction

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org The planets Mercury and Jupiter meet up for a conjunction today. Conjunction means that these two worlds stand north and south of one another in right ascension. (Right ascension on the sky’s dome is the equivalent of longitude here on Earth.) Mercury swings north of Jupiter at 17 hours Universal Time (12:00 noon Central Daylight Time) on March 16. In the Americas, this conjunction takes place during ... Full Story

Sky Tonight—March 15, Jupiter is your guide to Mercury in mid-March 2011

Courtesy of EarthSky A Clear Voice for Science Visit EarthSky at www.EarthSky.org If you can find the blazing planet Jupiter in your western sky after sunset, you are virtually assured of seeing Mercury, the solar system’s innermost planet. As long as your western horizon is free of obstruction – like houses, trees, or cloud cover – Mercury should be yours tonight. Remember to start your search soon after sunset, because these two worlds will set about 80 minutes after sundown ... Full Story
