Using Lasers To Shut Down Street Lights And Get Better Space Photos

Feb 20, 2015 by Udi Tirosh 36 Comments

One of the biggest obstacles of taking good astronomical photos is light pollution, this is why almost every tip article on night photos has a tip about getting away from the city. But what if you want to take photos in your driveway? In that case, street lights will most probably kill each and every one of your photos.

Astronaut Don Pettit (previously) has a neat little trick he uses to shut down that annoying street light he has just outside his driveway. He points a laser at the street light sensor which tricks the street light into thinking that it is still day outside and preserve energy by shutting down.

Jellyfish Stinging In Microscopic Slo-Mo Shows They Don’t Rub Against You, They Use Syringes

Have you been to the beach in the last few years? If so was the only thing you could think about was “Please don’t let that jellyfish touch me! Please don’t let that jellyfish touch me! Please don’t let that jellyfish touch me!”. And was that because of those slimy tentacles that smear venomous pain-inducing mucus on you?

I had those thoughts too. But it turns out that if you actually take a strong microscope coupled with a 2,200 fps Phantom Miro camera you see that it is not the slime that hurts you, it is millions of small syringes that extend from the jellyfish and inject venom into your skin.
