Hubble and Chandra Unveil Mysteries Concerning Dark Matter

From HubbleSite: “This collage shows images of six different galaxy clusters taken with NASA’s Hubble Space Telescope and Chandra X-ray Observatory. The clusters were observed in a study of how dark matter in clusters of galaxies behaves when the clusters collide. Seventy-two large cluster collisions were studied in total. Using visible-light images from Hubble, […]

Hubble Shows Evidence of Large Underground Ocean on Ganymede

From HubbleSite: “NASA’s Hubble Space Telescope observed a pair of auroral belts encircling the Jovian moon Ganymede. The belts were observed in ultraviolet light by the Space Telescope Imaging Spectrograph and are colored blue in this illustration. They are overlaid on a visible-light image of Ganymede taken by NASA’s Galileo orbiter. The locations of […]

Fifteen years ago, next week, Shuttle Discovery rocketed into orbit on a mission to dramatically service and repair the Hubble Space Telescope (HST). In doing so, the […]

Rough Cosmic Waters: Chandra X-ray Observatory Reveals 'Turbulent' Effect of Black Holes

From NASA: “Chandra observations of the Perseus and Virgo galaxy clusters suggest turbulence may be preventing hot gas there from cooling, addressing a long-standing question of galaxy clusters do not form large numbers of stars.” Image Credit: NASA/CXC/Stanford/I. Zhuravleva et al

This week, NASA announced that the Chandra X-ray Observatory, now in its 15th […]

Integral Component of Webb Space Telescope Undergoes, Survives 'Deep Freeze' Testing

From NASA: “The view from inside NASA Goddard’s Thermal Vacuum Chamber shows the JWST [James Webb Space Telescope] heart being lowered by crane in preparation of weeks of space environment testing.” An essential component of the James Webb Space Telescope has just completed and survived vacuum testing in extremely cold conditions.
