OPIC ESCO S WEN P. SCO AND STEr J. HE SCI, , ST ESA SA, NA IC A star is born: Molecular Cloud M16, imaged by the Hubble Space Telescope, is the birthplace of many new stars. IEW Defining the Hot, Turbulent Regions of Space X-rays from Chandra and optical data from Hubble form this image of a spiral galaxy (right) and an elliptical galaxy (left), which collided some 430 million light-years from Earth. AS A/ CX C/ M IT/ ST SC I In space, x-rays are found in areas of strong magnetic fields, extreme gravity, very high temperatures (millions of degrees), and explosive forces. Since its launch in 1999, the Chandra X-ray Telescope has helped astronomers understand how galaxies formed from the Big Bang, estimate the age of the universe, and determine whether the universe will expand forever—or collapse. (The science points to perpetual expansion.) With power equivalent to a human’s ability to read a stop sign from 12 miles away, Chandra has produced valuable studies of supernovae remnants and black holes. In fact, Chandra can detect electromagnetic energy from particles up to the second before they fall into a black hole. Chandra’s scientific mission is expected to continue for at least another decade. N imagine 21
