For #WorldOceanMonth, we dove in on the etymology of the words and how NASA’s view helps us better understand the huge and the tiny wanderers. Video Description: 00:00 A woman with brown and purple hair, wearing a black shirt, talks in front of a backdrop with illustrations of several planets. The word wanderers is spelled phonetically over her head. 00:05 She holds her hands out and an illustration of a telescope appears in one and an illustration of a microscope in the other. 00:13 The word planetes spelled phonetically in the Greek alphabet appears above her head. 00:15 A close-up of half of the Sun, with a tiny Mercury transiting it, looking like a fast-moving black spot. 00:19 Fade to a top-down view of the orbits of Mercury and Venus, with parts of the orbits of Earth and Mars zipping in and out of frame. Each orbit is labeled. The planets move at different speeds, sometimes passing each other. 00:26 Back to the woman talking. 00:27 Montage of microscope view of plankton, which are various shapes and shades of green and brown, floating around in water. 00:34 Animation of a cross-section of ocean water. About halfway down, the water transitions from light blue and sunlit to darker blue without light. In the upper half, animated plankton float. As the animation progresses, the lit section of the ocean shrinks up, and the plankton move closer to the surface. 00:40 Back to the woman talking. 00:42 Video of Ingenuity helicopter taking off from the surface of Mars, which is a reddish beige. 00:43 Animation of a spacecraft nearing Venus, which wipes to an ultraviolet view. 00:45 Animation of the TESS spacecraft against a starry backdrop. 00:47 Back to the woman talking. 00:48 Animation of the PACE spacecraft, with Earth’s atmosphere in the background. 00:51 Back to the woman talking. #NASA #Space #Planets #SolarSystem #Ocean #OceanMonth #Plankton」6月29日 23時33分
