Only at the Pole – the sun circles around the horizon in 24h here is a time-lapse of nearly 5 days from March 08-13, 2017. So only a few days until sunset so in the course of 360° the sun moves a bit closer to the horizon.
This animation shows a full, one year time lapse animation of surface winds from Jan 1, 2018 until Jan 1, 2019, over the North Atlantic. The data come from the National Weather Service’s GFS numerical weather model . Blue colors represent slower winds. Greens and yellows are faster winds. Streamlines show the direction of the wind in each frame of the animation.
This is one of the first 4K time lapse animations generated from earth.nullschool.net. The animation took 48 hours to render as 3,000 individual frames encoded to video.
Notice how a few hurricanes appear in July but then August is quiet, only for things to really pick up in September. Also notice how fall and winter bring massive storm systems to the upper North Atlantic (Greenland, Iceland, Ireland, the UK, Norway).
As nighttime arrives, previously obscured light sources begin to dazzle the eye. City lights sprawl across Earth’s surface. A constant glow hovers in the upper atmosphere. Beyond Earth, starlight fills in the darkness of the cosmos.
From the vantage point of space, we can get a unique view of each of these nighttime spectacles. On October 7, 2018, an astronaut aboard the International Space Station (ISS) shot this photograph while orbiting at an altitude of more than 400 kilometers (250 miles) over Australia. In this view, stars appear more numerous along the image center, where the plane of our disk-shaped Milky Way galaxy extends into space.
The oranges (above) and greens (in the video below) enveloping Earth are known as airglow—diffuse bands of light that stretch 50 to 400 miles into our atmosphere. The phenomenon typically occurs when molecules (mostly nitrogen and oxygen) are energized by ultraviolet (UV) radiation from sunlight. To release that energy, atoms in the lower atmosphere bump into each other and lose energy in the collision. But the upper atmosphere is thinner, so atoms are less likely to collide. Instead they release their energy by emitting photons. The result is colorful airglow. [leggi tutto]
Spiders are the most amazing web architects and using slow motion the Earth Unplugged team captured this Orb spider building a stunning structure. Subscribe to BBC Earth Unplugged for more amazing animal videos https://www.youtube.com/channel/UCbwp…

Si parte dall’uomo e si va verso l’infinitamente piccolo o verso l’infinitamente grande. Un modo per cercare di percepire (per quanto possible) i “due mondi” (chi usa “Flash” ha una interattività maggiore qui: The Scale of the Universe 2)
