Hubble Images Become Tactile 3-D Experience for the Blind
Three-dimensional printers are transforming the business, medical, and consumer landscape by creating a vast variety of objects, including airplane parts, football cleats, lamps, jewelry, and even artificial human bones.
Great Observatories Team Up to Discover Ultra-Bright Young Galaxies
NASA's Hubble Space Telescope and Spitzer Space Telescope joined forces to discover and characterize four unusually bright galaxies as they appeared more than 13 billion years ago, just 500 million years after the big bang. Although Hubble has previously identified galaxies at this early epoch, astronomers were surprised to find objects that are about 10 to 20 times more luminous than anything seen previously.
Hubble Unveils a Deep Sea of Small and Faint Early Galaxies
Scientists have long suspected there must be a hidden population of small, faint galaxies that were responsible during the universe's early years for producing a majority of stars now present in the cosmos. At last Hubble has found them in the deepest ultraviolet-light exposures made of the early universe. This underlying population is 100 times more abundant in the universe than their more massive cousins that were detected previously.
