Comet dust: Planet Mercury's 'invisible paint'

more »

Scientists have long puzzled over the planet Mercury's excessively dark surface. New research suggests that carbon from passing comets could be the planet's mystery darkening agent.

Nickel oxide films enhance solar-driven splitting of water

Science Focus

original post »

As a society, we have seen a tremendous increase in sustainable technology over the last decade. From recycling, to LEDs, to LEED Certified buildings, and to battery-powered cars, clear progress has been made. Today, scientists continue to push boundaries on sustainable technology, shaping public policy and the future in the process.

One area of active research is sustainable solar-produced fuels. Researchers are developing artificial photosynthetic systems that are designed to replicate the natural process of photosynthesis, which harnesses solar energy to convert water and carbon dioxide into oxygen and sugars. These systems, both natural and synthetic, involve chemically converting water into oxygen gas and hydrogen gas.

Usually, our water-splitting processes rely on electrolysis—running electricity through water to trigger a reaction that splits it. In order to carry out this process using solar energy, systems require stable, light-absorbing electrodes. Unfortunately, the solution conditions required to carryout water electrolysis often cause electrodes to degrade, which has hampered progress toward developing efficient, stable artificial photosynthetic systems.

Quantum computers could greatly accelerate machine learning

more »

(Phys.org)—For the first time, physicists have performed machine learning on a photonic quantum computer, demonstrating that quantum computers may be able to exponentially speed up the rate at which certain machine learning tasks are performed—in some cases, reducing the time from hundreds of thousands of years to mere seconds. The new method takes advantage of quantum entanglement, in which two or more objects are so strongly related that paradoxical effects often arise since a measurement on one object instantaneously affects the other. Here, quantum entanglement provides a very fast way to classify vectors into one of two categories, a task that is at the core of machine learning.

Monogram Carina Nebula - Breathtaking Universe Stickers

Here's a great sheet of stickers featuring a beautiful image from deep space

Galaxies, Stars and Nebulae series

A gorgeous set of oval stickers showing the area surrounding the stellar cluster NGC 2467, located in the southern constellation of Puppis ("The Stern"). With an age of a few million years at most, it is a very active stellar nursery, where new stars are born continuously from large clouds of dust and gas.

The image, looking like a colourful cosmic ghost or a gigantic celestial Mandrill, contains the open clusters Haffner 18 (centre) and Haffner 19 (middle right: it is located inside the smaller pink region - the lower eye of the Mandrill), as well as vast areas of ionised gas.

The bright star at the centre of the largest pink region on the bottom of the image is HD 64315, a massive young star that is helping shaping the structure of the whole nebular region.

Earthlike 'Star Wars' tatooines may be common

more »

Luke Skywalker’s home in “Star Wars” is the desert planet Tatooine, with twin sunsets because it orbits two stars. So far, only uninhabitable gas-giant planets have been identified circling such binary stars, and many researchers believe rocky planets cannot form there. Now, mathematical simulations show that Earthlike, solid planets such as Tatooine likely exist and may be widespread.
