Software can do so much to make our lives easier but it can do more than just that. Virgin Atlantic is using it to not only make things easier but also to help reduce their carbon footprint in a big way. Their fuel saving software named the OSyS Fuel Efficiency System went live in July of 2012 and allows them to accurately monitor at over 300 different points on each and every flight. Being able to review their fuel use in this manner has enabled them to save money to the tune of an estimated £20 million annually but that’s not all. It also makes it possible for them to cut out 92,000 tons of carbon which will make a huge difference in the environment.

Microsoft is also taking big steps to reduce their carbon footprint by selling their software online, via web download, a decision that has shrunk the product’s carbon footprint by 88% when you compare it to the alternative which would be producing, packaging, and actually shipping a physical DVD. Not only does it reduce the environmental impact, it also saves both Microsoft and the customer money and the customer can have the item they want nearly immediately. Everybody, and the environment, wins.

When talking about the universe, it helps to have some short-hand. Not that it makes much sense either way, but saying the observed universe has a diameter of 2.48 10E26 meters makes for smoother conversation than trying to figure out how to say 248,000,000,000,000,000,000,000,000. It also helps to consider relative sizes. For instance, the diameter of the local universe is about 1/35th the diameter of the observed universe. Local is an interesting term, given the diameter represented everything within 13.1 billion light years of planet Earth.

The largest features found in the local universe are superclusters. These are composed of galaxies, clouds, and nebulae found relatively close to one another amid the vastness of space. The Milky Way is a spiral galaxy only 1.14 10E21 meters in diameter. It’s small compared to the largest known galaxy IC1101 but comparable to other nearby spiral galaxies and certainly nothing to be ashamed of.
