Can you visit LIGO in Louisiana?
LIGO in Livingston Louisiana offers field trips on a daily basis Tuesday – Friday. LIGO’s Science Education Center is a unique field trip opportunity that allows students to interact with scientists and engineers doing real science, and to experience hands on science through our interactive exhibit hall.
Where are the LIGO detectors located?
The two primary research centers are located at the California Institute of Technology (Caltech) in Pasadena, California, and the Massachusetts Institute of Technology (MIT) in Cambridge, Massachusetts. The detector sites in Hanford and Livingston are home to the interferometers that make LIGO an “observatory”.
Why is LIGO in Louisiana?
Such vibrations can drown out the telltale signals of gravitational waves in a sea of noise, just as light pollution drowns out the fragile light of distant stars. In the end, the desert of eastern Washington, and the forests of Louisiana were chosen as the locations of LIGO’s two detectors.
How many detections has LIGO?
Observations are made in “runs”. As of December 2019, LIGO has made 3 runs, and made 50 detections of gravitational waves. Maintenance and upgrades of the detectors are made between runs….LIGO.

Why is LIGO important?
As an antenna able to detect vibrations in the ‘medium’ of space-time, LIGO is akin to a human ear able to detect vibrations in a medium like air or water. LIGO has removed a veil of mystery on the Universe and in so doing, has ushered in exciting new research in physics, astronomy, and astrophysics.
How much did LIGO cost?
LIGO has cost American taxpayers about $1.1 billion. That is how much the National Science Foundation has spent on the project over the past 40 years, according to the Times.
Where is the Virgo interferometer?
Pisa, Italy
Located outside of Pisa, Italy, Virgo is gravitational wave interferometer with arms 3 km long (LIGO’s are 4 km long). Virgo is funded by the European Gravitational Observatory (EGO), a collaboration of the Italian and French governments.
What can LIGO detect?
Though its mission is to detect gravitational waves from some of the most violent and energetic processes in the Universe, the data LIGO collects may have far-reaching effects on many areas of physics including gravitation, relativity, astrophysics, cosmology, particle physics, and nuclear physics.
What does LIGO stand for?
PSU LIGO: LIGO stands for Laser Interferometer Gravitational-wave Observatory.
How many gravitational waves have been detected date?
In all, the observation network has now observed 50 gravitational-wave events (see ‘Cosmic clashes’). Most of the events are mergers of two black holes. The detectors have also caught sight of a handful of collisions between two neutron stars and at least one merger of one neutron star and one black hole.
What is LIGO looking for?
It is the world’s largest gravitational wave observatory and a marvel of precision engineering. Comprising two enormous laser interferometers located 3000 kilometers apart, LIGO exploits the physical properties of light and of space itself to detect and understand the origins of gravitational waves (GW).
