It's time to go to Hawaii—at least, if you're MOSFIRE, a new near-infrared spectrometer that's now on its way to the W. M. Keck Observatory, atop Mauna Kea. But the powerful new instrument, six feet in diameter, about a dozen feet in length, and weighing in at 4,500 pounds—10,000 if you include the mount and packing crate—isn't going there to surf. MOSFIRE will be the newest weapon in the Keck's arsenal to survey the cosmos, helping astronomers learn about star formation, galaxy formation, and the early universe.
