LIGO Observatory near Livingston LA Operational Again

The Laser Interferometer Gravitational-Wave Observatory is made up of two detectors, this one in Livingston, La., and one near Hanford, Wash. The detectors use giant arms in the shape of an "L" to measure tiny ripples in the fabric of the universe. Credit: Caltech/MIT/LIGO Lab

After Three Years of Upgrades, LIGO is Fully Operational Again
Have you noticed a lack of gravitational wave announcements the past couple of years? Well, now it is time to get ready for an onslaught, as the Laser Interferometric Gravitational-Wave Observatory (LIGO) starts a new 20-month observation run today, May 24th after a 3-year hiatus.
LIGO has been offline for the last three years, getting some serious new upgrades. One upgrade, called “quantum squeezing,” reduces detector noise to improve its ability to sense gravitational waves.
Astronomers expect this upgrade could double the sensitivity of LIGO. This will allow black hole mergers to be seen more clearly, and it could also allow LIGO to see mergers that are fainter or farther away. Or, perhaps it could even detect new kinds of mergers that have never been seen before.

That’s when my headaches came back.

very cool

Now they find a DSLD neighborhood has been built right in their sightline and a fight is going to start because some Karen and Kyle want to uplight their crepe myrtles with 5000w floods.

Dear LIGO:
Sleep lightly
Ascension be comin’ for you

I got to work on it when it was first constructed. 2.5 mile from the center station to the end of the detector array both runs 90degrees from each other.

He's joking but there are DSLD cookie cutter neighborhoods just a stones throw away from LIGO

so? LOL
they are detecting gravitational waves from millions of light years away
Karen ain’t in the way

Oh I thought you actually believed that someone plopped down a mcmansion between their lasers

Livingston is listed as one few spots in America where you supposedly still can see the Milky Way fairly well (& regularly) considering 95% of nation is polluted with eletric lighting at night. It happens to be a lot closer & accessible than prime desolate spots like Death Valley, Ca and other West Coast deserts.
I've been wanting to go visit Livingston since I've sadly only seen the Milky Way twice in my life as a life-long city-boy. Can anybody near Livingston confirm regular Milky Way sightings?

Skies in Livingston Parish may be more clear skies than those of Baton Rouge or New Orleans, but there are several nearby areas with much less light pollution.
On the light pollution Bortle scale, most of LP would be a Bortle 4 or 5 which is "moderate," and on cloudless nights the Milky Way is visible although not with much detail. North of Baton Rouge, southeast to southwest of Natchez the skies are a Bortle 3 in which the Milky Way and some galaxies and nebulae are very prominent.

Well yeah, LIGO doesn't have human eyes. It sees things differently than we do. I'm sure the real pictures are out there. They just aren't interesting at all to the everyday person. Idiots would be lining up to say "all that tax money for that?!?"
