    Lisa Nip How humans could evolve to survive in space

    If we hope to one day leave Earth and explore the universe, our bodies are going to have to get a lot better at surviving the harsh conditions of space. Using synthetic biology, Lisa Nip hopes to harness special powers from microbes on Earth — such as the ability to withstand radiation — to make humans more fit for exploring space. "We're approaching a time during which we'll have the capacity to decide our own genetic destiny," Nip says. "Augmenting the human body with new abilities is no longer a question of how, but of when."

    Carter Emmart A 3D atlas of the universe

    For the last 12 years, Carter Emmart has been coordinating the efforts of scientists, artists and programmers to build a complete 3D visualization of our known universe. He demos this stunning tour and explains how it's being shared with facilities around the world.

    Fred Jansen How to land on a comet

    As manager of the Rosetta mission, Fred Jansen was responsible for the successful 2014 landing of a probe on the comet known as 67P/Churyumov-Gerasimenko. In this fascinating and funny talk, Jansen reveals some of the intricate calculations that went into landing the Philae probe on a comet 500 million kilometers from Earth — and shares some incredible photographs taken along the way.

    Sara Seager The search for planets beyond our solar system

    Every star we see in the sky has at least one planet orbiting it, says astronomer Sara Seager. So what do we know about these exoplanets, and how can we find out more? Seager introduces her favorite set of exoplanets and shows new technology that can help collect information about them — and even help us look for exoplanets with life.

    Carolyn Porco This is Saturn

    Planetary scientist Carolyn Porco shows images from the Cassini voyage to Saturn, focusing on its largest moon, Titan, and on frozen Enceladus, which seems to shoot jets of ice.

    Aomawa Shields How we'll find life on other planets

    Astronomer Aomawa Shields searches for clues that life might exist elsewhere in the universe by examining the atmospheres of distant exoplanets. When she isn't exploring the heavens, the classically trained actor (and TED Fellow) looks for ways to engage young women in the sciences using theater, writing and visual art. "Maybe one day they'll join the ranks of astronomers who are full of contradictions," she says, "and use their backgrounds to discover, once and for all, that we are truly not alone in the universe."

    Angelo Vermeulen How to go to space, without having to go to space

    "We will start inhabiting outer space," says Angelo Vermeulen, crew commander of a NASA-funded Mars simulation. "It might take 50 years or it might take 500 years, but it's going to happen." In this charming talk, the TED Senior Fellow describes some of his official work to make sure humans are prepared for life in deep space ... and shares a fascinating art project in which he challenged people worldwide to design homes we might live in there.
