With the aid of a $5 million grant from NASA<\/abbr>, a University of Hawaiʻi<\/span> at Mānoa<\/a> team of astronomers is developing ATLAS<\/abbr> (Asteroid Terrestrial-Impact Last Alert System) to identify dangerous asteroids before their final plunge to Earth.<\/p>\n

The Institute for Astronomy’s<\/a> team is on track to build and operate an asteroid detection system that will patrol the visible sky twice a night looking for faint objects moving through space. Astronomers expect the system to be fully operational by the end of 2015.<\/p>\n

The team predicts the system will offer a one-week warning for a 50-yard diameter asteroid or “city killer” and three weeks for a 150 yard-diameter “county killer.”<\/p>\n

“That’s enough time to evacuate the area of people, take measures to protect buildings and other infrastructure, and be alert to a tsunami danger generated by ocean impacts,” said 糖心视频<\/abbr> Mānoa astronomer and ATLAS<\/abbr> project head John Tonry<\/strong>.<\/p>\n

ATLAS<\/abbr> will complement the Institute for Astronomy’s Pan-STARRS project, a system that searches for large “killer asteroids” years, decades and even centuries before impact with Earth. Whereas Pan-STARRS takes a month to complete one sweep of the sky in a deep but narrow survey, ATLAS<\/abbr> will search the sky in a closer and wider path to help identify the smaller asteroids that hit Earth much more frequently.<\/p>\n

As well as searching for asteroids, ATLAS<\/abbr> will also look for dwarf planets, supernova explosions and flashes of light that occur when a star is gobbled up by a supermassive black hole in a distant galaxy.<\/p>\n
