An experiment recreates the crust of Saturn's moon Europa
more »
Water, salts and gases dissolved in the huge ocean that scientists believe could exist below Europa´s icy crust can rise to the surface generating the enigmatic geological formations associated to red-tinged materials that can be seen on this Jupiter's satellite. This is confirmed by the experiment carried out in the laboratory with water, carbon dioxide and magnesium sulfate.

You're orbiting Venus in your spaceship. As you circle the hellish planet below, there comes a moment when the Sun is shining from directly behind you, and you're looking down the length of your spaceship's shadow. What do you see?
This.

Atomically thick metal membranes
more »
For the first time researchers have shown that freestanding metal membranes consisting of a single layer of atoms can be stable under ambient conditions. The success and promise of atomically thin carbon, in which carbon atoms are arranged in a honeycomb lattice, also known as graphene has triggered enormous enthusiasm for other two dimensional materials, for example, hexagonal boron nitride and molybdenum sulphide. These materials share a common structural aspect, namely, they are layered materials that one can think of as individual atomic planes that can be pulled away from their bulk 3D structure.

Polar Ring Galaxy NGC 2685
more »
NGC 2685 is a confirmed polar ring galaxy - a rare type of galaxy with stars, gas and dust orbiting in rings perpendicular to the plane of a flat galactic disk. The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring. Still, observed properties of NGC 2685 suggest that the rotating ring structure is remarkably old and stable. In this sharp view of the peculiar system also known as Arp 336 or the Helix galaxy, the strange, perpendicular rings are easy to trace as they pass in front of the galactic disk, along with other disturbed outer structures. NGC 2685 is about 50,000 light-years across and 40 million light-years away in the constellation Ursa Major.
