8 00:00:21,180 --> 00:00:24,940 We're in for a wild ride like that again, because the sun is ramping up and we're right 9 00:00:24,940 --> 00:00:26,480 in the middle of it. 10 00:00:26,480 --> 00:00:29,560 Welcome to Cosmos in a pod this space and astronomy series. 11 00:00:29,560 --> 00:00:32,000 Please like, comment, share and subscribe. 12 00:00:32,000 --> 00:00:37,600 We're diving deep today into the solar maximum, this crazy period of intense solar activity 13 00:00:37,600 --> 00:00:39,760 that happens every 11 years. 14 00:00:39,760 --> 00:00:43,640 What's fascinating here is that it's all tied to the sun's magnetic field. 15 00:00:43,640 --> 00:00:47,720 It flips every 11 years, kind of like a giant cosmic magnet turning itself over, and that 16 00:00:47,720 --> 00:00:50,080 flip triggers a surge in activity. 17 00:00:50,080 --> 00:00:54,640 We're in solar cycle 25 right now, and it's been a real humdinger, even stronger than 18 00:00:54,640 --> 00:00:55,920 scientists initially predicted. 19 00:00:55,920 --> 00:00:59,040 So it's not just some distant cosmic light show. 20 00:00:59,040 --> 00:01:02,300 What happens on the sun directly affects us here on Earth. 21 00:01:02,300 --> 00:01:04,600 But how exactly does this solar cycle work? 22 00:01:04,600 --> 00:01:07,840 Think of it like a heartbeat, a rhythmic pulse of energy. 23 00:01:07,840 --> 00:01:13,000 The sun goes through periods of high activity with lots of sunspots, solar flares and coronal 24 00:01:13,000 --> 00:01:18,600 mass ejections, which are these massive bursts of plasma and magnetic field. 25 00:01:18,600 --> 00:01:22,160 Then it settles down into a quieter period before ramping up again. 26 00:01:22,160 --> 00:01:26,720 And that whole cycle from quiet to wild and back again takes about 11 years. 27 00:01:26,720 --> 00:01:30,440 And right now we're in the peak of that wild phase, the solar maximum, right? 28 00:01:30,440 --> 00:01:31,440 Exactly. 29 00:01:31,440 --> 00:01:36,240 NASA officially declared the solar maximum's arrival back in October 2024. 30 00:01:36,240 --> 00:01:40,480 And I remember reading about that gigantic sunspot active region 3364. 31 00:01:40,480 --> 00:01:43,800 It was like 17 times the size of Earth. 32 00:01:43,800 --> 00:01:48,220 That thing was spitting out solar flares like crazy, causing geomagnetic storms and those 33 00:01:48,220 --> 00:01:50,200 incredible auroras we talked about earlier. 34 00:01:50,200 --> 00:01:51,400 It was quite a sight. 35 00:01:51,400 --> 00:01:54,560 But those beautiful auroras are just one side of the coin. 36 00:01:54,560 --> 00:01:58,120 These solar storms can pack a real punch when it comes to our technology. 37 00:01:58,120 --> 00:02:00,800 Yeah, I mean, we're so reliant on technology these days. 38 00:02:00,800 --> 00:02:02,640 GPS satellites, power grids. 39 00:02:02,640 --> 00:02:06,200 It's almost like we've built this fragile world and now the sun is reminding us just 40 00:02:06,200 --> 00:02:07,760 how vulnerable it all is. 41 00:02:07,760 --> 00:02:08,760 You're absolutely right. 42 00:02:08,760 --> 00:02:13,440 Disrupted communications, power grid failures, even damage to satellites. 43 00:02:13,440 --> 00:02:17,980 These are all very real possibilities during intense solar activity. 44 00:02:17,980 --> 00:02:19,860 And we've seen it happen before, haven't we? 45 00:02:19,860 --> 00:02:21,560 Like with the Carrington event you mentioned earlier. 46 00:02:21,560 --> 00:02:23,840 That was back in 1859, right? 47 00:02:23,840 --> 00:02:26,560 Where telegraph systems go in haywire all over the place. 48 00:02:26,560 --> 00:02:27,560 Absolutely. 49 00:02:27,560 --> 00:02:29,360 Telegraph operators were getting shocked. 50 00:02:29,360 --> 00:02:31,260 Telegraph paper was catching fire. 51 00:02:31,260 --> 00:02:34,000 And auroras were visible as far south as the Caribbean. 52 00:02:34,000 --> 00:02:39,320 It was a global event and it showed us just how powerful the sun can be. 53 00:02:39,320 --> 00:02:40,320 That's incredible. 54 00:02:40,320 --> 00:02:41,600 But it wasn't just a one-off event, right? 55 00:02:41,600 --> 00:02:46,320 I mean, haven't there been other instances where solar storms have messed with our technology? 56 00:02:46,320 --> 00:02:47,400 Oh, definitely. 57 00:02:47,400 --> 00:02:50,320 Take the New York Railroad storm in 1921, for example. 58 00:02:50,320 --> 00:02:54,680 It caused widespread disruption to telegraph and telephone systems, even sparking fires 59 00:02:54,680 --> 00:02:56,720 and some railroad signal equipment. 60 00:02:56,720 --> 00:03:01,360 And then more recently in 1989, we had the Quebec blackout, where a solar storm triggered 61 00:03:01,360 --> 00:03:05,400 a major power outage, leaving millions of people in the dark for hours. 62 00:03:05,400 --> 00:03:11,460 Those events really drive home how dependent we are on our technology and how vulnerable 63 00:03:11,460 --> 00:03:12,720 it is to these solar outbursts. 64 00:03:12,720 --> 00:03:17,360 I mean, if a solar storm could cause that much chaos back then, what could it do to 65 00:03:17,360 --> 00:03:19,880 our super connected world today? 66 00:03:19,880 --> 00:03:21,040 That's the big question, isn't it? 67 00:03:21,040 --> 00:03:25,520 And it's one we need to be seriously thinking about because the stakes are much higher now. 68 00:03:25,520 --> 00:03:31,400 Just imagine a widespread internet outage or GPS systems going down or a major power 69 00:03:31,400 --> 00:03:32,660 grid failure. 70 00:03:32,660 --> 00:03:35,380 The consequences would be immense. 71 00:03:35,380 --> 00:03:37,680 It is a sobering thought, isn't it? 72 00:03:37,680 --> 00:03:43,960 Our world runs on this delicate web of interconnected systems and a powerful solar storm could disrupt 73 00:03:43,960 --> 00:03:47,160 that web in ways we can't even fully anticipate. 74 00:03:47,160 --> 00:03:48,160 Exactly. 75 00:03:48,160 --> 00:03:49,160 And it's not just about inconvenience. 76 00:03:49,160 --> 00:03:53,360 We're talking about potential disruptions to emergency services, financial systems, 77 00:03:53,360 --> 00:03:54,920 transportation networks. 78 00:03:54,920 --> 00:03:56,760 The ripple effects could be enormous. 79 00:03:56,760 --> 00:03:58,240 You're hitting on a crucial point there. 80 00:03:58,240 --> 00:03:59,560 The impact wouldn't just be technological. 81 00:03:59,560 --> 00:04:02,660 It would be deeply societal and economic as well. 82 00:04:02,660 --> 00:04:03,700 So what can we do about it? 83 00:04:03,700 --> 00:04:07,140 Are we just sitting ducks waiting for the next big solar storm to hit? 84 00:04:07,140 --> 00:04:08,140 Not at all. 85 00:04:08,140 --> 00:04:10,520 The good news is that we're not starting from scratch. 86 00:04:10,520 --> 00:04:14,920 We've learned a lot from past events and we're actively working on ways to protect ourselves. 87 00:04:14,920 --> 00:04:17,120 OK, so what's being done? 88 00:04:17,120 --> 00:04:20,920 What are some of the strategies to mitigate the risks from these solar storms? 89 00:04:20,920 --> 00:04:25,440 Well, for one, we're getting much better at monitoring and predicting space weather. 90 00:04:25,440 --> 00:04:28,600 Think of it like terrestrial weather forecasting. 91 00:04:28,600 --> 00:04:33,000 But instead of tracking rain clouds and wind patterns, we're tracking solar flares and 92 00:04:33,000 --> 00:04:34,840 coronal mass ejections. 93 00:04:34,840 --> 00:04:40,060 So we're keeping a closer eye on the sun, trying to anticipate these outbursts. 94 00:04:40,060 --> 00:04:41,880 Are we getting any better at it? 95 00:04:41,880 --> 00:04:42,880 Absolutely. 96 00:04:42,880 --> 00:04:47,000 Scientists are constantly refining their models, using data from satellites and ground-based 97 00:04:47,000 --> 00:04:51,480 observatories to improve the accuracy of space weather forecasts. 98 00:04:51,480 --> 00:04:55,040 The goal is to give us as much warning as possible so we can take steps to protect our 99 00:04:55,040 --> 00:04:56,040 critical infrastructure. 100 00:04:56,040 --> 00:04:57,040 That makes sense. 101 00:04:57,040 --> 00:04:58,760 But what about the technology itself? 102 00:04:58,760 --> 00:05:01,960 Can we make it more resilient to these solar storms? 103 00:05:01,960 --> 00:05:04,160 That's another key area of focus. 104 00:05:04,160 --> 00:05:09,360 We're designing more robust satellites, hardening power grids against surges, and developing 105 00:05:09,360 --> 00:05:15,180 backup systems to ensure critical services can stay online, even during disruptions. 106 00:05:15,180 --> 00:05:18,160 So tougher satellites, more resilient power grids. 107 00:05:18,160 --> 00:05:20,160 What does that look like in practice? 108 00:05:20,160 --> 00:05:21,640 Think of it this way. 109 00:05:21,640 --> 00:05:26,320 Imagine a satellite with extra shielding to protect its sensitive electronics from the 110 00:05:26,320 --> 00:05:32,440 radiation blast of a solar flare or a power grid with strategically placed capacitors. 111 00:05:32,440 --> 00:05:37,600 That can absorb the excess energy from a geomagnetic storm, preventing widespread blackouts. 112 00:05:37,600 --> 00:05:40,880 These are just some examples of the innovations happening right now. 113 00:05:40,880 --> 00:05:41,880 That's really encouraging. 114 00:05:41,880 --> 00:05:45,920 It looks like we're taking this threat seriously and making real progress in safeguarding our 115 00:05:45,920 --> 00:05:47,200 technology. 116 00:05:47,200 --> 00:05:50,800 But all of this focus on protecting things here on Earth makes me think about the bigger 117 00:05:50,800 --> 00:05:51,800 picture. 118 00:05:51,800 --> 00:05:53,280 What about space exploration?
