Remarkable fluid dynamics animation of Earth’s ocean, colored by surface temperature, the best thing since NASA’s Perpetual Ocean visualization and Wattenberg + Viegas’s Windmap project

This is actually a test showing how sponges pump water through themselves for filter feeding!
They simply colored the water around them so you could easily see the process :D

Sponges will never cease to fascinate me!

Boiling lava in Marum crater

Ambrym is a large basaltic volcano with a 12-km-wide caldera. It is not only one of the most active volcanoes of Vanuatu, but also in the world. Ambrym’s caldera is a wide, impressive moon-like landscape containing an ash plain, cut by innumerable erosion gullies and containing several active craters and recent lava flows.

The caldera is believed to have formed during a major plinian eruption with dacitic pyroclastic flows about 1900 years ago. Activity after the caldera formation was concentrated around two vents that have become large complex craters called Marum and Benbow. Often, both Marum and Benbow (as well as other craters) contain small lava lakes, which occasionally erupt lava flows onto the caldera floor, or even exit the caldera through erosion gaps.

To capture close-up footage of this lava lake on the Pacific island of Vanuatu, Geoff Mackley and his colleagues had to brave excruciating heat and some rather precarious-looking abseiling.

Jupiter’s Irregular Satellites

The planet Jupiter has 67 confirmed moons. This gives it the largest retinue of moons with “reasonably secure” orbits of any planet in the Solar System. In fact, Jupiter and its moons are like a miniature solar system with the inner moons orbiting faster than the others. Eight of Jupiter’s moons are regular satellites, with prograde and nearly circular orbits that are not greatly inclined with respect to Jupiter’s equatorial plane. The remainder of Jupiter’s moons are irregular satellites, whose prograde and retrograde orbits are much farther from Jupiter and have high inclinations and eccentricities. These moons were probably captured by Jupiter from solar orbits. There are 17 recently discovered irregular satellites that have not yet been named.
