356 00:12:59,720 --> 00:13:02,360 We've really only just scratched the surface. 357 00:13:02,360 --> 00:13:04,320 The universe is full of surprises. 358 00:13:04,320 --> 00:13:06,440 And with every new exoplanet we discover, 359 00:13:06,440 --> 00:13:09,040 we're learning more about the incredible diversity 360 00:13:09,040 --> 00:13:11,760 of planetary systems out there. 361 00:13:11,760 --> 00:13:14,360 It's mind-boggling to think about all the strange 362 00:13:14,360 --> 00:13:16,800 and wonderful worlds that must exist, 363 00:13:16,800 --> 00:13:19,680 each with its own unique story to tell. 364 00:13:19,680 --> 00:13:22,200 It's almost like the universe has an endless imagination 365 00:13:22,200 --> 00:13:24,000 when it comes to creating planets. 366 00:13:24,000 --> 00:13:25,920 So what other weird and wonderful planets 367 00:13:25,920 --> 00:13:28,040 are out there that we haven't talked about yet? 368 00:13:28,040 --> 00:13:30,240 Well, we've discussed planets with extreme orbits 369 00:13:30,240 --> 00:13:31,040 and temperatures. 370 00:13:31,040 --> 00:13:33,720 But what about planets with extreme compositions? 371 00:13:33,720 --> 00:13:35,280 For example, there are planets that 372 00:13:35,280 --> 00:13:38,280 are thought to be made almost entirely of diamond. 373 00:13:38,280 --> 00:13:40,880 These planets formed in systems that were rich in carbon 374 00:13:40,880 --> 00:13:43,480 and under intense pressure and heat that carbon 375 00:13:43,480 --> 00:13:45,280 crystallized into diamond. 376 00:13:45,280 --> 00:13:46,560 Planets made of diamond. 377 00:13:46,560 --> 00:13:48,760 That sounds like something out of science fiction. 378 00:13:48,760 --> 00:13:50,840 But it's a good reminder that the universe operates 379 00:13:50,840 --> 00:13:52,680 on scales of physics and chemistry 380 00:13:52,680 --> 00:13:54,920 that are hard for us to comprehend. 381 00:13:54,920 --> 00:13:57,640 What other extreme compositions have we found? 382 00:13:57,640 --> 00:14:00,400 We found planets with molten iron rain, planets 383 00:14:00,400 --> 00:14:03,600 with atmospheres so thick they'd crush us instantly, 384 00:14:03,600 --> 00:14:05,440 and planets that are darker than coal, 385 00:14:05,440 --> 00:14:08,200 absorbing almost all the light that hits them. 386 00:14:08,200 --> 00:14:11,840 We've even found planets that seem to be made mostly of water. 387 00:14:11,840 --> 00:14:14,480 Giant ocean worlds with no land in sight. 388 00:14:14,480 --> 00:14:15,960 It makes you wonder what life would 389 00:14:15,960 --> 00:14:18,920 be like on these planets if it exists at all. 390 00:14:18,920 --> 00:14:21,200 What would a creature adapted to diamond rain 391 00:14:21,200 --> 00:14:23,440 or a perpetual ocean look like? 392 00:14:23,440 --> 00:14:24,960 It's both fascinating and a little bit 393 00:14:24,960 --> 00:14:26,400 terrifying to think about. 394 00:14:26,400 --> 00:14:27,280 It is. 395 00:14:27,280 --> 00:14:28,880 And it really stretches our definition 396 00:14:28,880 --> 00:14:31,080 of what we consider habitable. 397 00:14:31,080 --> 00:14:33,240 We tend to think of life as needing conditions 398 00:14:33,240 --> 00:14:34,160 similar to Earth. 399 00:14:34,160 --> 00:14:36,200 But these anomalous planets are showing us 400 00:14:36,200 --> 00:14:39,000 that life might be far more adaptable and resilient 401 00:14:39,000 --> 00:14:40,480 than we ever imagined. 402 00:14:40,480 --> 00:14:42,280 It's a humbling reminder that we're still 403 00:14:42,280 --> 00:14:46,240 very much in the early stages of exploring our universe. 404 00:14:46,240 --> 00:14:47,920 OK, let's shift gears a bit and talk 405 00:14:47,920 --> 00:14:53,320 about a particularly intriguing class of planets, rogue 406 00:14:53,320 --> 00:14:54,320 planets. 407 00:14:54,320 --> 00:14:56,680 What are they and what makes them so anomalous? 408 00:14:56,680 --> 00:14:59,520 Rogue planets are, in a sense, cosmic orphans. 409 00:14:59,520 --> 00:15:02,200 They're planets that have been ejected from their star systems 410 00:15:02,200 --> 00:15:03,840 either through gravitational interactions 411 00:15:03,840 --> 00:15:07,000 with other planets or through some other cataclysmic event. 412 00:15:07,000 --> 00:15:09,160 They wander through interstellar space 413 00:15:09,160 --> 00:15:11,640 unbound to any star drifting through the galaxy 414 00:15:11,640 --> 00:15:13,080 like cosmic nomads. 415 00:15:13,080 --> 00:15:14,960 So they're like planetary wanderers lost 416 00:15:14,960 --> 00:15:16,320 in the vastness of space. 417 00:15:16,320 --> 00:15:17,880 It's kind of a lonely thought, isn't it? 418 00:15:17,880 --> 00:15:18,380 It is. 419 00:15:18,380 --> 00:15:21,600 But it's also a reminder of the dynamic and often chaotic 420 00:15:21,600 --> 00:15:23,960 nature of planetary systems. 421 00:15:23,960 --> 00:15:26,320 We tend to think of planets as being neatly arranged 422 00:15:26,320 --> 00:15:27,320 around their stars. 423 00:15:27,320 --> 00:15:29,160 But the reality is that planetary systems 424 00:15:29,160 --> 00:15:32,480 can be incredibly unstable with planets being ejected 425 00:15:32,480 --> 00:15:33,960 or colliding with each other. 426 00:15:33,960 --> 00:15:36,520 It makes our own solar system seem remarkably peaceful 427 00:15:36,520 --> 00:15:38,520 and stable in comparison. 428 00:15:38,520 --> 00:15:40,680 One last question about rogue planets. 429 00:15:40,680 --> 00:15:42,720 If they're not orbiting a star, are they 430 00:15:42,720 --> 00:15:44,800 just frozen, lifeless worlds? 431 00:15:44,800 --> 00:15:46,160 Not necessarily. 432 00:15:46,160 --> 00:15:47,960 While they don't receive direct sunlight, 433 00:15:47,960 --> 00:15:50,520 rogue planets can still generate internal heat 434 00:15:50,520 --> 00:15:53,640 through radioactive decay and tidal forces. 435 00:15:53,640 --> 00:15:56,720 Some scientists believe that this internal heat, combined 436 00:15:56,720 --> 00:15:59,080 with potential geothermal activity, 437 00:15:59,080 --> 00:16:02,440 could create subsurface oceans of liquid water, even 438 00:16:02,440 --> 00:16:04,680 on planets far from any star. 439 00:16:04,680 --> 00:16:07,280 So even in the darkest corners of space, 440 00:16:07,280 --> 00:16:10,760 there could be pockets of warmth and liquid water potentially 441 00:16:10,760 --> 00:16:12,360 harboring life as we don't know it. 442 00:16:12,360 --> 00:16:13,360 It's an incredible thought. 443 00:16:13,360 --> 00:16:14,080 It really is. 444 00:16:14,080 --> 00:16:15,840 And it underscores the fact that we've only 445 00:16:15,840 --> 00:16:19,440 just begun to explore the vast tapestry of planetary diversity 446 00:16:19,440 --> 00:16:20,320 out there. 447 00:16:20,320 --> 00:16:22,880 Who knows what other strange and wonderful worlds 448 00:16:22,880 --> 00:16:24,400 are waiting to be discovered? 449 00:16:24,400 --> 00:16:26,200 That's what makes astronomy so exciting. 450 00:16:26,200 --> 00:16:28,080 With every new discovery, we're expanding 451 00:16:28,080 --> 00:16:29,440 our understanding of the universe 452 00:16:29,440 --> 00:16:30,800 and our place within it. 453 00:16:30,800 --> 00:16:32,440 And that's a journey that never gets old. 454 00:16:32,440 --> 00:16:33,200 Well said. 455 00:16:33,200 --> 00:16:36,200 It's a privilege to be a part of this grand exploration. 456 00:16:36,200 --> 00:16:38,720 And we can't wait to see what other mysteries the universe 457 00:16:38,720 --> 00:16:40,720 reveals to us in the years to come. 458 00:16:40,720 --> 00:16:42,600 And to all of you listening out there, 459 00:16:42,600 --> 00:16:44,880 keep looking up at the night sky. 460 00:16:44,880 --> 00:16:47,920 You never know what wonders you might discover. 461 00:16:47,920 --> 00:16:49,800 Thanks for joining us on this deep dive 462 00:16:49,800 --> 00:16:52,200 into the most anomalous planets. 463 00:16:52,200 --> 00:16:55,480 Don't forget to follow and subscribe to Cosmos in a Pod 464 00:16:55,480 --> 00:17:15,880 and our YouTube channel for more cosmic adventures.
