What is the universe made of? We only know a tiny fraction — 4 percent — of the answer. From our little corner of the cosmic map, how do we know what else is out there? Luckily, we have space messengers (otherwise known as cosmic rays) that bring us data from parts of the cosmos far beyond our reach. Veronica Bindi explains how cosmic rays transmit information about our universe from the great beyond.
"The man to my right started telling me about all the ways that the internet is degrading the English language. He brought up Facebook and he said: "to defriend, I mean is that a real word?”. I wanna pause on that question: what makes a word ‘real’?”- Anne Curzan, What makes a word “real”? TEDxUofM [x]
The Royal Observatory, Greenwich recently announced the winners of the 2014 international astronomy photography competition. These stunning pictures all received prizes, and the rest can be seen at the observatory’s annual free exhibition in England.

From the brilliant minds who brought you the Large Hadron Collider, you’ll hear talks on attempting nuclear fission in a school science lab, developing nanomaterials that interact with DNA, and much more.
The highest summit of Mount Kilimanjaro was once completely covered in ice. But since 1912, more than 80% of the mountain’s ice cover has melted, disappearing at an even faster rate in recent decades. Photographer Yann Arthus-Bertrand’s aerial photographs show how climate change has impacted the environment. He says, "It’s too late to be pessimistic — really too late. We have to be a part of the solution."
The great thing about imagining learning as cartography instead of as arbitrary hurdles you have to jump over is that you see a bit of coast line and that makes you want to see more.
At TEDxIndianapolis, John Green talks about how to inspire curiosity by explaining one of his strangest discoveries: Paper towns. He’s obsessed with paper towns, or fake towns that mapmakers use to make their maps unique (they can then sue another company for duplicating their map with the fake town). It’s a weird quirk of mapmaking, but it naturally sparks curiosity — as soon as you learn a bit, you want to know more.
Fabian Oefner is bringing art and science together. In this eye-catching series of clips, Oefner makes sound waves visible by placing colorful crystals over a speaker and filming their movement. The result is poetic and more than a little trippy.
What happens when you combine a macho Russian security guard and a whole lot of Barbie dolls?Russian artist Uldus Bakhtiozina creates portraits that challenge common stereotypes about gender and culture—all with a playful dose of irony. Her aesthetic is inspired by Victorian Era paintings, each featuring a clever modern update and a message about societal norms. These two portraits specifically explore the internal struggle of her subjects to balance their masculine and feminine sides.
