This Proba image shows the region around Samoylov Island, located within the Lena River Delta on the Laptev Sea coast of Northern Siberia. The small pear-shaped island of Samoylov in the lower middle of the image is one of the Delta’s more than 1 500 individual islands.
The Lena Delta, covering an area of about 32 000 square kilometres, is a haven for Arctic wildlife that transforms for five months each summer from frozen tundra to fertile wetlands. The Delta is located at the end of the 4400-km-long course of the Lena River, one of the longest rivers in the world. It is an important breeding ground for many migratory birds and supports diverse populations of fish and several marine mammals.
The largest Delta in the Arctic, the Lena Delta is a complex landscape that has evolved over thousands of years. The Holocene (the geological era extending back from the present to the last 10 000 years) Delta incorporates parts of an older accumulation plain, dating as far back as the mid-to-late Pleistocene Era. Samoylov Island is located in the central southern part of the Lena Delta, close to the Delta apex. Covering an area of 1200 hectares, it is representative of the active and the Holocene part of the Delta, estimated to back about 7000 years.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
