Short Flash from Enormous Explosion Solves Cosmic Mystery
Credit: Derek Fox/Penn State University Hubble Space Telescope image of the sky surrounding the afterglow and host galaxy of the HETE short burst of July 9, 2005. The circle indicates the region of sky that HETE saw the burst from; according to the HETE team we would find the burst within this region. The box, inset, indicates where the X-ray and optical afterglow of the burst was ultimately found. The colors indicate the intensity of red light (814 nm) as seen by the Advanced Camera for Surveys instrument

Trumpler 14: Bright Young Stars Mix It Up
Credit: NASA/CXC/Penn State/L.Townsley et al. Chandra's image of the star cluster Trumpler 14 shows about 1,600 stars and a diffuse glow from hot multimillion-degree X-ray-producing gas. The cluster has one of the hightest concentrations of massive, luminous stars in the Galaxy. Located on the edge of a giant molecular cloud, it is part of the Carina Complex which contains at least 8 star clusters.

New Microprinting Technique Improves Nanoscale Fabrication
A demonstration of microdisplacement printing, in which a weakly bound film is displaced by contact stamping with molecules that bind more strongly to the substrate. This process leaves a patterned film with regions of strongly bound molecules (where the weakly bound molecules were displaced) and regions of the remaining weakly bound molecules.
Brain Scientists Offer Insight Into Vision

Scientists Measure How Deep "Deep Impact" Was, With X-rays
False-color image of Comet Tempel 1 taken on 1 July 2005 with the Swift Ultraviolet Optical Telescope. The picture was formed from images taken separately through V, B, U, and Ultraviolet filters and corrected for the comet's motion before being combined. As a result, the background stars appear as a series of images in different colours.
