Peter Van de Graaf shares some of his favorites, from the late German tenor Fritz Wunderlich to American soprano Renee Fleming.
Following the meteorite strike in Chelyabinsk, Russia, asteroid detection systems are getting more attention.
A team of astronomers at the University of Hawaii is developing Asteroid Terrestrial-Impact Last Alert System (ATLAS), with the help of a $5 million NASA grant.
Under the guidance of ATLAS project head John Tonry, the team is working to build a series of small grounded telescopes to track near earth objects or NEOs.
The B612 Foundation is a nonprofit that’s working to build a space telescope to do the same thing.
Officials with the ATLAS project think it’s possible to “provide a useful degree of warning for most impacts, meaning a day for a 30 kiloton ‘town killer’, a week for a five megaton ‘city killer’ or three weeks for a 100 megaton ‘county killer.'”
