...smallest known exoplanet—a planet orbiting a star other than the Sun—announced Tuesday by European astronomers. The new planet, Gliese 581 e, is 1.9 times the size of Earth and 80 times smaller than the first exoplanet, which was discovered in 1995. The solar system where the planet was found is 20.5 light years away and can be found in the constellation Libra. Members of the CFA, which has played a major role in the search for exoplanets, heralded the discovery as momentous. “This discovery can be compared to what happened...
According to Pearson, there could be a rich and diverse ecosystem that thrives beneath the glaciers. She even suggested that there could perhaps be life on other icy planets in the solar system; below the Martian ice caps or in the ice-covered oceans of Europa, a moon of Jupiter...
When we think of green buildings, we tend to think of new ones--the kind of high-tech, solar-paneled masterpieces that make the covers of architecture magazines. But the U.S. has more than 100 million existing homes, and it would be incredibly wasteful (not to mention totally unrealistic) to tear them all down and replace them with greener versions. An enormous amount of energy and resources went into the construction of those dwellings. And it would take an average of 65 years for the reduced carbon emissions from a new energy-efficient home to make up for the resources...
...meantime, you can make small changes to begin greening your home. You don't need solar panels or rooftop wind turbines. You just need a good caulking gun. Start by thinking of your house as a submarine, and plug the leaks in your walls, doors and windows. Be sure to insulate the attic and the basement, since up to 20% of energy costs can come from heat loss in those spaces. A home energy audit is also a good idea; energysavers.gov details how to do one yourself as well as how to go about hiring a professional. So be like...
Harvard has also recently put up wind turbines on the roof of the Holyoke Center and solar panels on some University-owned buildings...
