00:00 China's Mars rover Zhurong has uncovered weird polygon structures under the surface of the red planet.
00:07 It's a mystery, hinting at the presence of water and maybe even past Martian life.
00:12 The rover spotted 16 of these polygonal wedges about 35 feet below the ground.
00:18 It did it by using ground penetrating radar.
00:21 I mean, NASA also has seen similar stuff before.
00:25 But this is the first time people have used ground penetrating radar to check it out.
00:31 Chinese scientists think these shapes might be left by freeze-thaw cycles.
00:36 You can think of it as our planet's winter and spring processes.
00:40 Experts say these shapes could be from around 3.7 to 2.9 billion years old.
00:46 That's it for today.
