Mystery of weird green lasers over Hawaii has now been solved

A series of green laser beams descending from the sky appeared over the islands of Hawaii back on January 28th.
The phenomenon first came to light when footage recorded by a camera at an observatory atop Hawaii's tallest peak was published on social media.

At the time, Japanese scientists at the National Astronomical Observatory of Japan (NAOJ) believed that the laser beams were being produced by NASA's orbiting ICESat-2 satellite which is used to monitor the levels of sea ice in connection with global warming.

Earlier this month, however, NASA scientist Dr. Martino, Anthony J - who has worked on the probe - played down this suggestion, instead implying that the lasers must have come from something else.
"His colleagues, Dr. Alvaro Ivanoff et al., did a simulation of the trajectory of satellites that have a similar instrument and found a most likely candidate as the ACDL instrument by the Chinese Daqi-1/AEMS satellite," the Japanese scientists wrote.

"We really appreciate their efforts in the identification of the light. We are sorry about our confusion related to this event and its potential impact on the ICESat-2 team."

Having launched in April last year, China's Daqi-1 satellite performs a very similar function to NASA's satellite and uses LIDAR (which utilizes lasers) to monitor global carbon and pollution levels.

You can check out the footage captured of the lasers below.

Thanks for the dissertation and yes, I certainly spelled the word incorrectly. Sincerely thank you for the constructive criticism and the correction thanks to you I now know what that bloody acronym stands for now!!! Oh, and by the way, I didn't mean to say laser, I mean to say Maser (Microwave amplification by stimulated emission of radiation)

I thought they've been saying it was from a Chinese satellite unless I am mistaken.

One of many articles. Lasers from Chinese satellites.

When I were a lad our school's physics teacher clearly didn't know that.  A whole generation of south-Notts yobs still think it means Light And Sound Emitting Radiation.  I think he got most of his knowledge from Star Wars. It was cool when we bashed the chalkboard dusters to illuminate the beams' ruby paths.  We probably actually learned quite a lot about diffraction 'n' stuff, even if we did have to add the sound effects ourselves.  Pee-ow!

So if it's just lasers from satellites then why are they not observable EVERYWHERE, ALL THE TIME, then it would be common knowledge and when they show up in Hawaii everyone knows what it is, cuz they're everywhere, right. Or do they only make measurements in Hawaii then?
