Planet Hunting, Down to Earth Credit: European Southern Observatory Two teams of researchers are now competing to develop a device that could profoundly change our understanding of the universe…but you’d be forgiven if you mistook it for a vaguely menacing hair-restoration product. Called a “laser frequency comb,” these are special laser systems that rapidly emit pulses of light across a wide range of frequencies or colors. In a plot of the emitted light, each distinct frequency appears as a peak; collectively, all the frequencies resemble a fine-toothed comb. And by examining starlight through the teeth of a laser comb, astronomers could begin finding Earth-like extrasolar planets on the cheap using ground-based observatories rather than expensive space telescopes.
Massive Biometric Project Gives Millions of Indians an ID In India, hundreds of millions of impoverished people have no ID—which means no bank account, credit, insurance, or government aid.Photo: Jonathan Torgovnik; Fingerprints: Getty The courtyard, just off a busy street in a Delhi slum called Mongolpuri, is buzzing with people—men in plastic sandals arguing with one another, women in saris holding babies on their hips, skinny young guys chattering on cheap cell phones. New arrivals take up positions at the end of a long queue leading to the gated entry of a low cement building. Every so often, a worker opens the gate briefly and people elbow their way inside onto a dimly lit stairway, four or five on each step. Slowly they work their way upward to a second-story landing, where they are stopped again by a steel grille. After a long wait, a lean woman in a sequined red sari, three children in tow, has finally made it to the head of the line.
Stephen Hawking: 'There is no heaven; it's a fairy story' A belief that heaven or an afterlife awaits us is a "fairy story" for people afraid of death, Stephen Hawking has said. In a dismissal that underlines his firm rejection of religious comforts, Britain's most eminent scientist said there was nothing beyond the moment when the brain flickers for the final time. Hawking, who was diagnosed with motor neurone disease at the age of 21, shares his thoughts on death, human purpose and our chance existence in an exclusive interview with the Guardian today.
15 Beautiful & Mystical Space Photos These eerie, dark, pillar-like structures - part of the Eagle Nebula - are columns of cool, interstellar hydrogen gas and dust that serve as incubators for new stars - Hubble Space Telescope 1995. On its 100,000th orbit of planet Earth, the Hubble Space Telescope peered into a small portion of the Tarantula Nebula near the star cluster NGC 2074, unveiling its stellar nursery. The region is a firestorm of raw stellar creation, triggered perhaps by a nearby supernova. The Elegant Universe: Pt 1 The Elegant Universe: Part 3 PBS Airdate: November 4, 2003 NARRATOR: Now, on NOVA, take a thrill ride into a world stranger than science fiction, where you play the game by breaking some rules, where a new view of the universe pushes you beyond the limits of your wildest imagination.
Wiki Summarizer WikiSummarizer is a Web-based application specializing in automatic summarization of Wikipedia articles. Automatic summarization is the creation of a shortened version of a text by a computer program. The result is a summary that presents the most important points of the original text. A summary is a shorter version of the original information. It highlights the major points from the much longer article. The Incredible Beauty of the Orion Nebula Learn about the beauty of the Orion Nebula. Photo: NASA Goddard Space Flight Center The Orion Nebula is one of the brightest in the night sky and lies south of Orion’s Belt. It is 1344 (plus or minus 20) light years away and is the closest huge star formation area to earth. As such, it is the most photographed in the night sky and has taught us much about star and planetary formation.
The Most Astounding Images Of Space Astounding Images Of Space: Orion Nebula In 2006, the Hubble Space Telescope captured this incredibly intricate image of the Orion Nebula. This nebula is a celestial wonder just south of Orion’s Belt and holds the title of the most photographed feature of the night sky. What’s more, the Orion Nebula is visible to the naked eye. It’s helpful, too: the Orion Nebula has aided astronomers in studying star and planetary systems.
