👁The most mysterious star in the universe
‌
🗣Subtitle: Farsi | English | Turkish

👣Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

👁Finding planets around other stars
‌
🗣Subtitle: Farsi | English | Turkish

👣How do we find planets -- even habitable planets -- around other stars? By looking for tiny dimming as a planet passes in front of its sun, TED Fellow Lucianne Walkowicz and the Kepler mission have found some 1,200 potential new planetary systems. With new techniques, they may even find ones with the right conditions for life.

👁How radio telescopes show us unseen galaxies
‌
🗣Subtitle: Farsi | English

👣Our universe is strange, wonderful and vast, says astronomer Natasha Hurley-Walker. A spaceship can't carry you into its depths (yet) -- but a radio telescope can. In this mesmerizing talk, Hurley-Walker shows how she probes the mysteries of the universe using special technology that reveals light spectrums we can't see.

👁How to take a picture of a black hole
‌
🗣Subtitle: Farsi | English | Turkish

👣At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.

👁Inside the black hole image that made history
🗣Subtitle: Farsi | English | Turkish

👣At the center of a galaxy more than 55 million light-years away, there's a supermassive black hole with the mass of several billion suns. And now, for the first time ever, we can see it. Astrophysicist Sheperd Doeleman, head of the Event Horizon Telescope collaboration, speaks with TED's Chris Anderson about the iconic, first-ever image of a black hole -- and the epic, worldwide effort involved in capturing it.

👁What it takes to launch a telescope
🗣Subtitle: Farsi | English | Turkish

👣TED Fellow and astronomer Erika Hamden leads the team building FIREBall, a telescope that hangs from a giant balloon at the very edge of space and looks for clues about how stars are created. She takes us inside the roller-coaster, decade-long journey to get the telescope from an idea into orbit -- and shows how failure is inevitable when you're pushing the limits of knowledge.

👁How does your smartphone know your location?
🧠Wilton L. Virgo
🗣Subtitle: 🇬🇧English | 🇹🇷Turkish

👣GPS location apps on a smartphone can be very handy when mapping a travel route or finding nearby events. But how does your smartphone know where you are? Wilton L. Virgo explains how the answer lies 12,000 miles over your head, in an orbiting satellite that keeps time to the beat of an atomic clock powered by quantum mechanics. [Directed by Nick Hilditch, narrated by Addison Anderson].
