LIGO Expands Its Reach Across Universe in Search for Gravitational Waves





LIGO’s extended reach across the universe with the recent update to Advanced LIGO detectors – one in Hanford, Washington, and the other in Livingston, Louisiana. Prior to its upgrade, LIGO was able to detect gravitational waves from 40 to 10,000 Hz, but since aLIGO came online, the interferometers have been able to detect waves down to a frequency of just 10 Hz, thereby greatly extending LIGO's reach.




“The effect we are trying to measure is so tiny that it takes something like LIGO to measure it," says David Reitze, LIGO laboratory executive director. “It’s mindboggling." He goes on to say, “We have been deaf, but now we can hear them. We now expect to hear things we never expected as we open a new window of astronomy. This was a scientific Moon shot, and we did it, we landed on the Moon."
