TED 研究會員，凱莉·紐金特是小行星搜尋科學家團隊的一員，他們致力於發現和編錄我們最為古老和為數最多的宇宙鄰居。我們為什麼要密切觀測小行星呢？在這段簡短和充滿事實的演講中，紐金特闡釋了，小行星驚人的撞擊如何塑造著我們星球的命運，以及在適當的時間找到小行星，其意義不亞於拯救地球上的生命。

小行星尋者歷險記

Asteroids are relics from the birth of our solar system, some older than the continents or life on Earth. Scientists have cataloged over 13,000 near-Earth asteroids, tracking their orbits with remarkable precision, even predicting paths years in advance to within tens of kilometers. While a small asteroid exploded over Chelyabinsk, Russia just three years ago, a much larger one wiped out the dinosaurs 66 million years ago. By mapping these cosmic neighbors, humanity can prevent future catastrophic impacts before they happen.
