A team of U.S. cosmologists using the BICEP2 telescope at the South Pole announced this week that they have discovered the first direct evidence of the rapid inflation of the universe at the dawn of time, thanks in part to technology developed and built by the National Institute of Standards and Technology (NIST).

Photos of the Day: Introducing supersonic passenger planes

March 18, 2014 9:23 am | by NASA | News | Comments

The level of concern over sonic boom annoyance became so significant that the Federal Aviation Administration prohibited domestic civil supersonic flight over land in 1973. This prohibition helped quiet the skies and reduce potential impacts on the environment. However, it also dashed hopes of introducing supersonic overland passenger service within U.S. airspace during the Concorde era.
