Some stats as to the newsworthiness of this:

Keck II has had a laser for about 10 years.  Gemini, for probably 8.  Subaru, for 5.  Keck I, for 3.

(I was a laser spotter for Keck II from 2005-2009, and for Gemini from 2006-2008.  I joined Subaru in a different capacity, just as they were really getting their laser working.)

For years, it was a big thing to see even one laser in use, and a huge thing to see two (because then we got to make jokes about not crossing the streams).  But by 2011,  in theory, there were four functional lasers on the summit.

There was one night a couple years ago where all four were  supposed to be used.  Gemini's broke.

Also a couple years ago, Andrea Ghez - pretty much the biggest name in center-of-our-galaxy research - and her collaborators managed to get time on both Kecks, with lasers, at the same time, for the same target.

img.fark.net

So we kept waiting and hoping for a night that  everybody's laser would work.   Finally, this past weekend (night of May 17-18), all four got used at the same time - pointing at different targets.

img.fark.net

The next night (May 18-19), all four pointed at the same place at the same time.  Andrea Ghez and company were using both Kecks, and Andrea also had a program in the Gemini queue that just happened to pop up.  Shogo Nishiyama and company were using Subaru, and also happened to be aiming at the galactic center, studying different stuff.

Unfortunately, there were cirrus clouds... but the  next night (May 19-20), things cleared up for Takeshi Oka on Subaru (studying yet another aspect of the galactic center), while Andrea and her crew continued using both Kecks, and her program came up in the Gemini queue  again.

And now you know... the rest of the story of the video.

Great, now we're gonna be invaded by pissed-off aliens that we accidentally blinded.

Well, it's a darned good thing we blinded them then.

Wow.  Lasers pointing to the same place in the sky. I'm overwhelmed.

Why are we doing this?

I'm not asking from a smarmy frame, but I'd like to better understand the science behind blasting the galaxy centre with lasers?
 
2014-05-22 11:37:27 AM
Great! Now they're gonna shoot back
 
2014-05-22 11:39:56 AM
Do we have anything out in space that can photograph the intersect point, and beyond,  of those four beams?

Now just up the power and turn it into a planetary-based Death Star weapon.

No pew pew pew sound effects...

I'm disappointed.

So was the ship destroyed or not?

Put simply, they help the telescope focus better -- they help the telescope correct for distortion in the atmosphere.

My Chinook helicopter landed on the summit of Mauna Kea about three years before construction began on Keck I, and we had a snowball fight. The view is unsurpassed.

There's something awe-inspiring about that kind of precision.

The video is just begging for someone armed with After Effects to put in some laser-shooting sound and a nice explosion at the end.

Crewmannumber6: Great! Now they're gonna shoot back


Don't worry. It'll be about 56,000 years before the return shot hits us.

Was it the Gemini telescope, or some other one I'm thinking of, where they built two instruments to do interferometry with, but one broke or something, so they sent the undamaged unit to Chile'?

UNAUTHORIZED FINGER: My Chinook helicopter landed on the summit of Mauna Kea about three years before construction began on Keck I, and we had a snowball fight. The view is unsurpassed.


Lucky for you, you had a helicopter that can actually take off again with passengers after landing up there.  I think Blackhawks might manage it too, but anything else... I've heard stories of helicopters landing on the gravel pad around 13,000' ... and leaving by truck.

Yeah, we were almost as high as we were allowed without oxygen, I believe. , I think we're required to have O2 above 14,000 feet. Fortunately, with a Chinook, you can make a running take-off. Even a 10-foot roll can do the trick. It makes all the difference in the world.

I love context. Thanks. Much cooler now that I understand the serendipity of the event/
