@stellarmorticia Beautiful photo! Too bad there’s so much dust on the lens.

Oh, wait! Are those the sturs (sp?) I’ve heard so much about?

I’ve lived Chicago too long.

Hope you’re loving those nights!

For anyone still on whatever this platform is now, our paper on land use and light emission as observed from a high altitude balloon mission is now available! You can access it here: https://t.co/8O9XDT4qMf

Is stargazing a financial luxury?

@JenniferYuen1 @StBrianAerial And low flying planes!

[Ken Walczak @KWalzar]

How?! How is this not illegal? This car was a block away and this is the light it cast in our house. And I live on the 2nd floor! @StBrianAerial

@darkskychi Talk went great! Over 100 people there to hear about the importance of natural nights, the Palos UNSP and how to address light pollution for all of us animals. We may have some new @darkskychi recruits!

[ISS Above @ISSAboveYou]

Good evening @chicago! This is spectacular you (*) at 7:22pm tonight when the @Space_Station passed you by 260 miles above.

@RestoringDrknss Did you know that light pollution is limiting our ability to detect potentially hazardous asteroids? https://t.co/BDhH8WLOg7 If ground based observatories can’t see them coming we’re no better than dinosaurs. Turn down the lights and protect the planet!

Amazing talk with stunning visuals at today’s #AGU22 plenary by @BabakTafreshi Let’s hope it inspired more researchers to consider #ALAN as an environmental issue.

[Ken Walczak @KWalzar]

@TheCosmicRey @theAGU Me too!

@ActeLum @JohnBarentine @MayorFrey Oops, Austin is on the right. The georeferencing was me.

[Ken Walczak @KWalzar]

@ActeLum @JohnBarentine @MayorFrey On the left is the city of Oak Park and the Chicago neighborhood of Austin on the left. The crime data is from https://t.co/jLhigCIR17 and https://t.co/pDubIXYNkJ

[Ken Walczak @KWalzar]

@JohnBarentine @MayorFrey Is lighting the solution to crime or a panacea? Here is an unedited 2016 ISS image of two neighborhoods in and next to Chicago and the number of reported crimes that year.

[Dr. John Barentine FRAS @JohnBarentine]

Also, @MayorFrey: your statement that "criminals fear a well-lit street" is unfounded in fact. I can show you plenty of studies to the contrary.

If you're interested in learning what street lighting actually *can* do for communities, have someone on your staff contact me.

[Human Spaceflight @esaspaceflight]

Can you spot the difference? 🧐
These images were taken by European astronauts from the International @Space_Station 10 years apart, 400 km above #Earth.
They are the best source for scientists to map #LightPollution.

The rare time Chicago streetlights aren’t a significant contributor to light pollution 🙄

[Ken Walczak @KWalzar]

@JohnBarentine Are you thinking about a legal definition? If so the word “artificial” needs a lot of clarification. “ALAN” does not distinguish between useful or polluting light. Also the light on a microwave display is artificial, light, at night per the words. So… yes.

[Ken Walczak @KWalzar]

@remiboucher @JohnBarentine @USherbrooke Yay! Congrats and welcome to the UNSP family.

[Ken Walczak @KWalzar]

@skyglowberlin Mission accomplished. I’m teased!

[Ken Walczak @KWalzar]

My appearance on the @RestoringDrknss podcast just dropped. What can we learn from observing LP from the stratosphere? How can we get the lighting industry on board? (A nod to @skyglowberlin for inspiring many aspects of our work @AdlerPlanet) https://t.co/K2GZjYyXQ6
