- Using Biodiesel in the Winter (JourneytoForever.org)
"Like petroleum diesel fuel, biodiesel clouds when the weather gets cold, filling with little crystals of wax that can clog the fuel filter. When it gets colder still the biodiesel gels -- sets solid and won't flow or pour." 10-04
- Structure of the Cosmos (Wikipedia.org)
"A galaxy is a large cluster of stars held together by gravity." Includes Galaxy clouds, Galaxy clusters, Galaxy filaments, Galaxy subclusters, and Galaxy superclusters. 10-04

"The Huygens probe is plunging through the orange clouds of Saturn's moon Titan, and scientists hope to soon have their first glimpse of the mysterious moon." 1-05

"This is one of the world's 10 poorest countries; life expectancy is a mere 37 years; two-thirds of the population live on less than a dollar a day; one in six adults is HIV positive, and nearly half the population of 12 million faces starvation in coming months if help doesn't arrive soon."
"That's 5 million people, which is half the population of London or New York City."
"Malawi is in deep trouble after a fourth straight season of failed rains, which made farmlands and fields bone dry. November was supposed to usher in the rainy season -- but the skies were a clear blue and no clouds are in sight."
"The majority of Malawians are subsistence farmers - and they are crying out for help." 12-05
- -12-11-05 Life Began in Space? (Scientific American)
"Louis Allamandola and his colleagues at the NASA Ames Research Center have created primitive cells of a sort—empty, two-layer membranes (see image)—from elementary chemicals, exposed to conditions like those in interstellar clouds. 'Scientists believe the molecules needed to make a cell's membrane, and thus for the origin of life, are all over space,' Allamandola says. 'This discovery implies that life could be everywhere in the universe.' " 12-05
- -01-05-06 Experiments Help Explain "Floppy" Space Molecule (Physorg.com)
"A laboratory method developed for making and analyzing cold, concentrated samples of a mysterious 'floppy' molecule thought to be abundant only in outer space has revealed new data that help explain the molecule's properties."
"The advance, described in the Jan. 6 issue of Science,* is a step toward overcoming a decades-old challenge in chemistry--explaining reactions that occur within very cold clouds among the stars, and perhaps for developing new chemical processes." 01-06
- Reflection Nebulae (Wikipedia.org)
"In astronomy, reflection nebulae are clouds of dust which are simply reflecting the light of a nearby star or stars. The nearby star or stars are not hot enough to cause ionization in the gas of the nebula like in emission nebulae but are bright enough to give sufficient scattering to make the dust visible. Thus, the frequency spectrum shown by reflection nebulae is similar to that of the illuminating stars." Also spelled "nebulas." 01-06
- Types of Nebulae (NinePlanets.org)
"Originally, the word 'nebula' referred to almost any extended astronomical object (other than planets and comets). The etymological root of 'nebula' means 'cloud'. As is usual in astronomy, the old terminology survives in modern usage in sometimes confusing ways. We sometimes use the word 'nebula' to refer to galaxies, various types of star clusters and various kinds of interstellar dust/gas clouds. More strictly speaking, the word 'nebula' should be reserved for gas and dust clouds and not for groups of stars." Also spelled "nebulas." 01-06

"European scientists released new photos of Venus’ south pole Thursday, revealing a swirling mass of sulfuric acid clouds powered by 220 mph winds." 04-06
- Rain Barrels (RainBarrelGuide.com)
"To illustrate how important and how limited a resource freshwater is in our world, consider the following. More than 70 percent of the Earth's surface is covered by water, but only 2.5% of this supply is considered fresh water. The rest is found in the form of salt water in the oceans. Of the fresh water that exists, most is locked up in glaciers and ice caps. Water can also be found in the form of clouds and humidity in the soil. That leaves us 3/10 of 1 percent found in the form of lakes, rivers and streams. Unfortunately, much of this small amount of freshwater is in danger of drying up through desertification or becoming so contaminated that it cannot be used for human consumption. Changing our habits of water use can help to abate this growing problem." 08-07

"Earlier this month, the world's first coal-fired power plant designed to capture and store carbon dioxide that it produces began operations in Spremberg [Germany]. The pilot plant has been built at a power station that, under Communist rule last century, used to belch out clouds of sulfurous smoke from burning brown coal, or lignite. 'Industrial history is being written,' says Tuomo Hatakka, chair of the European board of Vattenfall, the Swedish power company behind the new plant. Indeed, the development of carbon capture and storage (CCS) technology is seen by many experts as essential to help the world cut carbon-dioxide emissions in coal-fired power stations." 12-08
- -06-28-09 The Suns's Protection is Not Constant (NewScientist.com)
"The sun protects us from cosmic rays and dust from beyond the solar system by enveloping us in the heliosphere - a bubble of solar wind that extends past Pluto. These cosmic rays would damage the ozone layer, and interstellar dust could dim sunlight and trigger an ice age. However, when the solar system passes through very dense gas and dust clouds, the heliosphere can shrink until its edge is inside Earth's orbit." 06-09
- Gigantic Dust Cloud Threatens Food Supplies (Independent News - Lean)
"Gigantic dust clouds swirling over China are threatening the world's most populous country with the first-ever 'ecological meltdown', experts here warn."
"As the crisis continues, Mr Brown predicts, the world will soon feel the pinch. So far China has compensated for its falling harvests by eating stocks, but soon it will have to buy massive amounts of grain on world markets. He warns: 'Grain prices could double – impoverishing more people in a shorter period of time than any event in history. It would create a world food economy dominated by scarcity rather than by surpluses, as has been the case over most of the last half a century.' " Independent News is a British newspaper. 1-03
