Rather, it dramatically bends and comes back to its original position, forming a circular orbit. But at a critical distance, a light beam no longer spirals into the black hole. Nothing that comes too close can escape, not even light. To their surprise, such coherent eddies turned out to be mathematically equivalent to black holes.īlack holes are objects in space with a mass so great that they attract everything that comes within a certain distance of them. Haller and Beron-Vera were able to restore order in this chaos by isolating coherent water islands from a sequence of satellite observations.
The rotating and drifting fluid motion appears chaotic to the observer both inside and outside an eddy. The challenge in finding such eddies is to pinpoint coherent water islands in a turbulent ocean. In a paper just published in the Journal of Fluid Mechanics, they develop a new mathematical technique to find water-transporting eddies with coherent boundaries. George Haller, Professor of Nonlinear Dynamics at ETH Zurich, and Francisco Beron-Vera, Research Professor of Oceanography at the University of Miami, have now come up with a solution to this problem.
However, scientists have been unable to quantify this impact so far, because the exact boundaries of these swirling water bodies have remained undetectable. Intriguingly, this could moderate the negative impact of melting sea ice in a warming climate. Their number is reportedly on the rise in the Southern Ocean, increasing the northward transport of warm and salty water. However, our climate is also influenced by huge eddies of over 150 kilometres in diameter that rotate and drift across the ocean. It is only 1.5 kilometers (0.24 km²) long, has a triangular appearance and rises up to 5 meters above sea level.Īpparently, the strange black color on the island is due to the poor resolution of the satellite image that some users attribute to rendering an error where the program probably assumed that the trees were sea.The mild winters experienced in Northern Europe are thanks to the Gulf Stream, which makes up part of those ocean currents spanning the globe that impact on the climate. It was discovered in 1820 by the Russian explorer Fabian Gottlieb von Bellingshausen, who named the island after his ship (“Восток” which means “East” in Russian). An uninhabited coral island in the central Pacific Ocean that is part of the Line Islands, belonging to the Republic of Kiribati. Indeed, the image of what some have confused with an alleged ‘ black hole‘in the middle of the ocean is the island of Vostok, also known as the island of Staver.
(Also: In the photos: this is what thunder and other terrestrial phenomena look like in space) “It’s a Island call Vostok which belongs to the Republic of Kiribati, what you see as black is actually a very dark green, it is a very dense forest made up of Pisonia trees, “explained one of the readers.

Other users have joked about the mysterious find, pointing out that it could be the island of the Lost series or even the pick of some giant.īut beyond these strange ideas, other people have managed to locate the island and explain what its particular appearance is due to. It wouldn’t make sense for a natural formation to be so black in some kind of atoll,” was one of the publication’s comments. “My first thought was that it was censored. (It may interest you: Diana Valencia: ‘There is no planet B, we only have this and we need to take care of it’)įor example, users indicated that it could be a place that would be censored within the platform. This image caught the attention of users of websites like Reddit, where several people began to formulate theories about what this strange event could be captured by satellite imagery.
