00:00NASA just hit 6,000 exoplanets discovered.
00:03But there's one planet we still haven't found.
00:05A true twin of Earth.
00:07It took just 30 years for NASA to uncover 6,000 worlds beyond our solar system.
00:11Three years ago, that number was only 5,000.
00:14Now, the discoveries are exploding.
00:17From gas giants like Jupiter to mysterious lava-covered orbs.
00:21Each one expands our idea of what's possible.
00:24Some even zip through space at over a million miles per hour.
00:27The milestone was announced near the anniversary of the first exoplanet discovered around a sun-like star, 51 Pegasi b, found in 1995.
00:36But unlike that discovery, this 6,000th world doesn't have a name.
00:40Why? Because planets are added constantly, and no single one holds the title.
00:45Right now, over 8,000 more planets are waiting to be confirmed.
00:49One of the newest, KMT-2023 BLG-1896Lb, a Neptune-like planet 16 times heavier than Earth.
00:57NASA's TESS and retired Kepler telescopes have led most of these discoveries.
01:02And with every planet added, we get closer to answering a haunting question.
01:07Are we alone?
01:08Because out of all 6,007 exoplanets, we still haven't found another Earth.
01:13At least, not yet.
01:14At least, not yet.
