The Obama Administration recently allocated money for high-speed train projects across the nation. Here at HuffPost Green, we think high speed rail is totally awesome, and we hope to see many great rail projects across the country. The definition of high-speed rail varies across the world, with the US Federal Railroad Administration defining it as a train that exceeds speeds of 110 mph, while other countries set the standard much higher. Many places in the world are way ahead of us on rail projects, but they certainly give us something to aspire to. Take a look at some of the world's most popular high-speed trains, and let us know which you like best!

Precursors of Life-Enabling Molecules in Orion Nebula
The Herschel Space Observatory has revealed the chemical fingerprints of potential life-enabling organic molecules in the Orion Nebula, a nearby stellar nursery in our Milky Way galaxy. The European Space Agency leads the Herschel mission with important participation from NASA.
This detailed-spectrum, obtained with the Heterodyne Instrument for the Far Infrared (HIFI) - one of Herschel's three innovative instruments - demonstrates the gold mine of information that Herschel-HIFI will provide on how organic molecules form in space.
