This is Scientific Americans 60-Second Science. I am Adam Hinterthuer. Got a minute? Earlier this month, NASA announced that an MIT Physics professor will lead a team of scientists on a new mission. The objective: build a giant radio telescope on the
UV Rays Strip Small Galaxies of Star Stuff紫外线辐射会阻止小星系形成 The sun spews out ultraviolet radiationthat's why you put on sunscreen. But the sun isn't the only UV-producing celestial body. Stars and supermassive black holes produ
Recently, some researchers in Australia were excited about messages from a distant galaxy. But it turns out that the signals were from a completely different source. The scientists at Parkes Observatory in Australia specialize in radio bursts- short

Is anyone out there? For over 40 years scientists have been searching for extraterrestrial intelligence, but theyve found nothing. Now the new Allen Telescope Array, a string of 350 radio telescopes, is being built 300 miles north of San Francisco a

Radio telescopes are not enough, says SETI scientist Art Chimes | Washington, DC 16 April 2010 When the search for extra-terrestrial life began a half-century ago, it was assumed that technological civilizations would broadcast more and more signals
There was now a pressing challenge to understand how black holes in their surrounding galaxies. To be so intertwined.,professor Andy Fabian in the Cambridge University is one astronomer who began to look. Like the ripples, they travel out from his

Deciding where to place a Wi-Fi router at home to minimise signal blackspots is a fine art. But a physicist has attempted to tackle the problem by mathematically working out the optimum position for a router. He studied how walls and reflections affe
