via crookedindifference:In 1996, scientists took a huge risk when they pointed the Hubble telescope to an inky field that they believed to be void of stars and planets. As images from Hubble are in constant demand, the worry was that devoting so much time to a black space would prove futile. Once the photons finally registered, though, that leap of faith proved fruitful: light from over three thousand galaxies illuminated the image. A few years and missions later, Hubble’s glimpse into what is known as the deep field has revealed that we are just one tiny part of a vast system comprising 100 billion galaxies.
There are moments and experiences that you remember forever. They are signposts that paint a new road ahead of us, and tweak our rear-view mirror so that we may never see the past the same way again. Our lives are full of them: First loves, births, deaths, that one best meal.
Experiencing the Hubble Ultra Deep Field is one of those moments. Take a sec and truly internalize what you’re seeing. When you stare into an empty piece of the universe and find it overflowing with galaxies just like our own, and not like our own at all, stretching to the beginning of time itself … if you are alive in the least bit, you are forever changed.
We are time travelers all.
How to defend Earth from asteroids - Phil Plait
What’s six miles wide and can end civilization in an instant? An asteroid — and there are lots of them out there. With humor and great visuals, Phil Plait enthralls the TEDxBoulder audience with all the ways asteroids can kill, and what we must do to avoid them. (Filmed at TEDxBoulder.)

Fantastic Fungi and the Forest Floor
Louie Schwartzberg is perhaps the finest time-lapse nature photographer working today. He’s behind the stunning bee footage that made a quick appearance in my YouTube video about how they see flowers in UV.
Here he talks to mycologist Paul Stamets about the importance of fungi to forest health. When you see a mushroom, you’re looking at the tip of an iceberg, the tiny fruit of an underground fungal web that can stretch over 2,200 acres and live for more than 2,000 years!!
Louie Schwartzberg’s films are available in an iOS app now, for free.
