How Cosmic Winds Stop Stars From Forming

"The evidence for this is that dust filaments in the HST (Hubble Space Telescope) image look like taffy being stretched out," says Jeffrey Kenney. "We’re seeing this decoupling, clearly, for the first time." Above, Hubble Space Telescope image of a spiral galaxy in the Coma cluster. (NASA, ESA, and Roberto Colombari)

  • IN SPACE - JULY 14: In this handout provided by the National Aeronautics and Space Administration (NASA), Pluto nearly fills the frame in this image from the Long Range Reconnaissance Imager (LORRI) aboard NASA's New Horizons spacecraft, taken on July 13, 2015, when the spacecraft was 476,000 miles (768,000 kilometers) from the surface. This is the last and most detailed image sent to Earth before the spacecraft's closest approach to Pluto. New Horizons spacecraft is nearing its July 14 fly-by when it will close to a distance of about 7,800 miles (12,500 kilometers). The 1,050-pound piano sized probe, which was launched January 19, 2006 aboard an Atlas V rocket from Cape Canaveral, Florida, is traveling 30,800 mph as it approaches.
