Plantations of nanorods on carpets of graphene capture the Sun's energy

more »
The Sun can be a better chemist, thanks to zinc oxide nanorod arrays grown on a graphene substrate and 'decorated' with dots of cadmium sulphide. In the presence of solar radiation, this combination of zero and one-dimensional semiconductor structures with two-dimensional graphene is a great catalyst for many chemical reactions.

Hydra emerges from the shadows

more »
Since its discovery in 2005, Pluto's moon Hydra has been known only as a fuzzy dot of uncertain shape, size, and reflectivity. Imaging obtained during New Horizons' historic transit of the Pluto-Charon system and transmitted to Earth early this morning has definitively resolved these fundamental properties of Pluto's outermost moon.

From mountains to moons: Multiple discoveries from NASA’s New Horizons Pluto mission

more »
Icy mountains on Pluto and a new, crisp view of its largest moon, Charon, are among the several discoveries announced Wednesday by the NASA's New Horizons team, just one day after the spacecraft's first ever Pluto flyby.

Jupiter twin discovered around solar twin

more »
So far, exoplanet surveys have been most sensitive to planetary systems that are populated in their inner regions by massive planets, down to a few times the mass of the Earth. This contrasts with our Solar System, where there are small rocky planets in the inner regions and gas giants like Jupiter farther out.

We have liftoff! 3D-printed, soft-bodied robot makes explosive jumps

Science Focus

original post »

Today's issue of Science describes a new robot that has so many cool features it was hard to cram them all into the headline. It's made with a 3D printer, which is used to create gradients between flexible and hard material. It carries its own fuel, enough for dozens of hops to new locations. And it moves by pointing itself in the right direction, then setting off a butane explosion underneath itself.

Flexible or soft-bodied robots are inspired in part by biology, where squishy creatures regularly outperform our most carefully engineered robots. Why is that? The authors of the new paper have a simple explanation: "One of the reasons biological systems often outperform engineered systems is that in nature, which employs self-organization for fabrication, added structural complexity comes at a minimal cost."

But, they argue, 3D printing has the potential to change that calculus. With the right printer, it's possible to create hardware that mixes several materials, each with distinctive properties. And those distinctive properties turned out to be needed for the design they were working on.

Tadpole Nebula, Auriga Constellation Star Sticker

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


tagged with: envelope sealers, star forming activity, awesome astronomy images, tnitac, tadpole nebula, auriga constellation, new born stars, hot young stars, star nursery, dust clouds, interstellar gas clouds

Galaxies, Stars and Nebulae series An awesome outer space picture featuring the Tadpole Nebula, a star forming hub located about 12000 light years away in the Auriga constellation.
This nebula is brimming with new-born stars, many as young as only a million years of age. It's called the Tadpole nebula because the masses of hot, young stars are blasting out ultraviolet radiation that has etched the gas into two tadpole-shaped pillars, called Sim 129 and130, the yellow forms that seem to be swimming away from the three red stars close to the centre of the picture.

Jupiter twin discovered around solar twin

more »
Astronomers have used the ESO 3.6-metre telescope to identify a planet just like Jupiter orbiting at the same distance from a Sun-like star, HIP 11915. According to current theories, the formation of Jupiter-mass planets plays an important role in shaping the architecture of planetary systems. The existence of a Jupiter-mass planet in a Jupiter-like orbit around a Sun-like star opens the possibility that the system of planets may be similar to our own Solar System.

NASA's New Horizons 'phones home' safe after Pluto flyby

more »
NASA's New Horizons spacecraft phoned home just before 9 p.m. EDT Tuesday to tell the mission team and the world it had accomplished the historic first-ever flyby of Pluto. The preprogrammed "phone call" ended a very suspenseful 21-hour waiting period. New Horizons had been instructed to spend the day gathering the maximum amount of data, and not communicating with Earth until it was beyond the Pluto system.
