Lonely galaxy 'lost in space'

more »
Although the Universe may seem spacious most galaxies are clumped together in groups or clusters and a neighbor is never far away. But this galaxy, known as NGC 6503, has found itself in a lonely position, shown here at the edge of a strangely empty patch of space called the Local Void.

New boron compounds for organic light-emitting diodes

more »
A new class of organic luminescent materials have been developed through the targeted introduction of boron atoms into the molecular structures. The compounds feature an intensive blue fluorescence and are therefore of interest for use in organic light-emitting diodes.

MIT’s cheetah robot can now autonomously detect and jump over hurdles

Science Focus

original post »

MIT's biomimetic robotics lab, which last year developed a free-running untethered cheetah robot capable of bounding along at 10mph, has now created a new version—Cheetah 2—that can autonomously jump over hurdles.

These aren't just token hurdles, either: the current version of the robot can clear obstacles that are up to 45 centimetres (18 inches) tall, while maintaining a steady speed of 5mph (8kph). 45 centimetres is about half the height of the robot.

While untethered jumping is already quite an achievement for a biomimetic robot, the way in which Cheetah 2 does it is even more impressive. There isn't a human pushing a "jump" button; Cheetah 2 is autonomous. Using on-board LIDAR, the robot can detect obstacles, estimate the distance to the object and how tall it is, and then adjust its stride so that it's perfectly placed to jump over.

A celestial butterfly emerges from its dusty chrysalis

more »
Some of the sharpest images ever made with ESO's Very Large Telescope have, for the first time, revealed what appears to be an ageing star giving birth to a butterfly-like planetary nebula. These observations of the red giant star L2 Puppis, from the ZIMPOL mode of the newly installed SPHERE instrument, also clearly showed a close stellar companion.

Lonely Galaxy 'Lost in Space'


Get larger image formats

This magnificent spiral galaxy is at the edge of what astronomers call the Local Void. The Local Void is a huge volume of space that is at least 150 million light-years across that doesn't seen to contain anything much. There are no obvious galaxies. This void is simply part of the structure of the universe where matter grows clumpy over time so that galaxies form clusters and chains, which are separated by regions mostly devoid of galaxies. This results in sort of a "soap bubble" structure on large scales. The galaxy, as photographed by NASA's Hubble Space Telescope, is especially colorful where bright red patches of gas can be seen scattered through its spiral arms. Bright blue regions contain newly forming stars. Dark brown dust lanes snake across the galaxy's bright arms and center, giving it a mottled appearance.

Milky Way Galaxy - Our Beautiful Neighborhood Poster

Here's a great poster featuring a beautiful image from deep space

Milky Way Galaxy - Our Beautiful Neighborhood In this spectacular image, observations using infrared light and X-ray light see through the obscuring dust and reveal the intense activity near the galactic core. Note that the center of the galaxy is located within the bright white region to the right of and just below the middle of the image. The swirling core of our galaxy harbors hundreds of thousands of stars that cannot be seen in visible light. These stars heat the nearby gas and dust. These dusty clouds glow in infrared light and reveal their often dramatic shapes. Some of these clouds harbor stellar nurseries that are forming new generations of stars. Like the downtown of a large city, the center of our galaxy is a crowded, active, and vibrant place. The galactic center is marked by the bright patch in the lower right. Along the left side are large arcs of warm gas that have been heated by clusters of bright massive stars. Winds and radiation from these stars create the complex structures seen in the gas throughout the image.This sweeping panorama is one of the sharpest infrared pictures ever made of the galactic center region. Hundreds of small dots show emission from material around black holes and other dense stellar objects. A supermassive black hole -- some four million times more massive than the Sun -- resides within the bright region in the lower right. The diffuse X-ray light comes from gas heated to millions of degrees by outflows from the supermassive black hole, winds from giant stars, and stellar explosions. This central region is the most energetic place in our galaxy.
