Aomawa Shields is a woman of “contradictions.” An astronomer and astrobiologist, she searches for exoplanets where life might exist by using computer models to calculate the kind of atmosphere they’d need to support it. And she’s also a classically trained actor, who — through her organization Rising Stargirls — teaches astronomy to middle school girls of color using theater, writing and visual art to […]
“Are we alone? Is there life out there?” asks Sara Seager on the stage in Session 4 of TED2015. “These questions have been around for thousands of years since the days of the Greek philosophers. I’m here to tell you just how close we are getting.” Seager is a professor at MIT who has been referred […]
When Justin Dowd worked as a food runner at a restaurant, he would sometimes doodle on the chalkboard in the kitchen. He had no idea that this skill — coupled with his ability to explain physics — would one day win him a trip to space. The science writer and animator who created the TED-Ed lesson “Could comets […]
Scientific research is generating far more data than the average researcher can get through. Meanwhile, modern computing has yet to catch up with the superior discernment of the human eye. The solution? Enlist the help of citizen scientists. British astronomer and web developer Robert Simpson is part of the online platform Zooniverse, which lets more than one […]
Astronomer Andrew Connolly begins by telling us that in 1781, English composer, technologist and composer Sir William Herschel noticed something unusual, a little bit of data that was wrong. This was the discovery of a new planet, Uranus. (“A name that has entertained countelss generations of children.”) Just last week NASA announced 517 new planets, almost doubled […]
“The universe is teeming with planets,” and Jeremy Kasdin, an astronomer at Princeton University, wants to see them. Not in the way they’ve been detected so far, but directly. He wants to build a space telescope that will image a planet around another star and tell if it harbors life. There is probably one per star […]
In a surprise talk tonight, Allan Adams took the stage to explain a remarkable discovery announced just yesterday. And since he’s here and is amazing, Randall Munroe of xkcd illustrated the talk. As Adams tells us, if you look into the night sky, you see stars … and if you look further, you see more stars. […]
Physicist Brian Green promises he will tell the audience at TED 2014 the whole history of the universe in four minutes. “Forgive me,” he says, “if I leave out a detail here or there.” He does it with two metaphors. One from the beginning till now, and another from now till the end. The universe […]
Nigerian astronomer Johnson Urama wants to promote the future of astronomy in Africa by looking deep into history. With his African Cultural Astronomy Project, he is gathering the lost ancient astronomical traditions and stories of indigenous Africa, hoping to show modern Africans that the science of the skies is relevant to their past, present and future. […]
On July 20, 1969, Neil Armstrong became the first human to walk on the moon. Moon Day is held every July 20 to commemorate this momentous feat. 43 years later, humanity is still looking to the sky, mesmerized by lunar bodies. However, it is not just Earth’s moon we’re studying anymore. With better satellites and […]
Today may go down in history as The Day the Earth Smiled. Or, at least, that is what TED speaker Carolyn Porco (watch her talk) is hoping. Today from 9:27 to 9:42 pm GMT, the Cassini spaceship — an unmanned ship studying Saturn — will be taking a photograph of Saturn and its ring system. And […]
Huddle around the radio, all. TED Radio Hour’s second season is under way and episode two, “Peering into Space” premieres today. Host Guy Raz says that this episode may even be his favorite created so far. In an interview with the TED Blog, he said, “It totally changed my world … I think people who […]
Honor Harger isn’t your typical artist. Or your typical astronomer. At the TEDSalon London Spring 2011, Harger shared how she brings these two seemingly unrelated disciplines together — the study of sound and the study of space — to record the songs of planets, moons and quasars. Her talk is called “A history of the universe in […]
TED playlists are collections of talks around a topic, built for you in a thoughtful sequence to illuminate ideas in context. This weekend, three new playlists are available: “Ancient clues,” “Planes, trains and automobiles” and “Are we alone in the universe?” Ancient clues Five fascinating talks by archaeologists and evolutionary biologists about humanity’s beginnings and […]
Astronomer Jill Tarter wants us all to ask the question, “Are we alone?” As director of the SETI Institute (it stands for the Search for Extraterrestrial Intelligence), Tarter is dedicated to seeking the answer, as well as to imparting upon one and all the importance of the search. In 2009, Tarter was awarded the prestigious […]
