Jedidah Isler: How I fell in love with quasars, blazars and our incredible universe

04:19 minutes · Filmed Mar 2015 · Posted Apr 2015 · TED2015

Jedidah Isler first fell in love with the night sky as a little girl. Now she’s an astrophysicist who studies supermassive hyperactive black holes: quasars. In this short talk, she takes us trillions of kilometers from Earth to introduce us to these objects that can be 10 billion times the mass of the sun — and which shoot powerful jet streams of particles in our direction.

A 50-foot-long carnivore who hunted its prey in rivers 97 million years ago, the spinosaurus is a "dragon from deep time." Paleontologist Nizar Ibrahim and his crew found new fossils, hidden in cliffs of the Moroccan Sahara desert, that are helping us learn more about the first swimming dinosaur -- who might also be the largest carnivorous dinosaur of all.

As kids, we all get advice from parents and teachers that seems strange, even confusing.

Quote of the Week

As an astrophysicist, I have the awesome privilege of studying some of the most exotic objects in our universe: supermassive, hyperactive black holes. Weighing one to 10 billion times the mass of our own sun, these galactic black holes are devouring material at a rate of upwards of 1,000 times more than your 'average' supermassive black hole."

Nonetheless, the hedge fund manager and philanthropist is concerned that a laser focus on profits is, as he puts it, "threatening the very underpinnings of society." In this thoughtful, passionate talk, he outlines his planned counter-offensive, which centers on the concept of "justness." Watch »

While we like to imagine little green men on Mars, it’s far more likely that life on other planets will be microbial. Planetary scientist Nathalie Cabrol takes us inside the search for microbes on Mars, starting in the remote lakes of the Andes mountains. This extreme environment — with its thin atmosphere and scorched land — approximates the surface of Mars about 3.5 billion years ago. How microbes adapt to survive here may just show us where to look on Mars. Watch »
