This is a mosaic image, one of the largest ever taken by NASA's Hubble Space Telescope of the Crab Nebula, a six-light-year-wide expanding remnant of a star's supernova explosion. Japanese and Chinese astronomers recorded this violent event nearly 1,000 years ago in 1054, as did, almost certainly, Native Americans.

Freeze! Watching alloys change from liquid to solid could lead to better metals

more »

If you put a camera in the ice machine and watched water turn into ice, the process would look simple. But the mechanism behind liquids turning to solids is actually quite complex, and understanding it better could improve design and production of metals. A recent investigation aboard the International Space Station contributed to that understanding.

Old-looking galaxy in a young universe: Astronomers find dust in the early universe

more »

Dust plays an extremely important role in the universe -- both in the formation of planets and new stars. But the earliest galaxies had no dust, only gas. Now an international team of astronomers has discovered a dust-filled galaxy from the very early universe. The discovery demonstrates that galaxies were very quickly enriched with dust particles containing elements such as carbon and oxygen, which could form planets.

Dwarf planet Ceres continues to puzzle scientists as NASA's Dawn spacecraft gets closer to being captured into orbit around the object. The latest images from Dawn, taken nearly 29,000 miles (46,000 kilometers) from Ceres, reveal that a bright spot that stands out in previous images lies close to yet another bright area.

Living on the edge: Stars found far from galaxy center

more »

Astronomers using data from NASA's Wide-field Infrared Survey Explorer, or WISE, have found a cluster of stars forming at the very edge of our Milky Way galaxy. This is the first time astronomers have found stars being born in such a remote location. Clouds of star-forming material at very high latitudes away from the galactic plane are rare and, in general, are not expected to form stars.

Images capture a multi-star system in the making

Science Focus

original post »

Many of the stars in our galaxy don't orbit alone; systems of two, three, or even more stars are common. These have provided us important windows into the Universe in general. Type-Ia supernovae, which we use to measure cosmic distances, are triggered when two orbiting stars collide. Pulsars get sped up by the gas of a companion star until they rotate every few milliseconds. And changes in a star's motion can reveal an otherwise hidden companion, such as a stellar-mass black hole.

Despite their importance, however, we haven't really learned much about the formation of multi-star systems. While it was once proposed that they formed when one star gravitationally captured a second, surveys show that groups of orbiting bodies are more common when stars are young. This suggests that these systems form together before gravitational interactions kick some of the members out of the group. The challenge with imaging their formation is that stars form very quickly in astronomical terms, taking on the order of a hundred thousand years.

Now, researchers have been able to image one of these systems in the process of formation. By looking at a star forming field in the Perseus region, they've been able to spot a single protostar that's accompanied by three additional condensing regions, all of which should reach the protostar stage within the next 40,000 years.

Light, meet matter: Single-photon quantum memory in diamond optical phonons at room temperature

more »

(Phys.org)—Photonic quantum technologies – including cryptography, enhanced measurement and information processing – face a conundrum: They require single photons, but these are difficult to create, manipulate and measure. At the same time, quantum memories enable these technologies by acting as a photonic buffer. Therefore, an ideal part of the solution would be a single-photon on-demand read/write quantum memory. To date, however, development of a practical single-photon quantum memory has been stymied by (1) the need for high efficiency, (2) the read/write lasers used introducing noise that contaminates the quantum state, and (3) decoherence of the information stored in the memory.

What if one day, your computer, TV or smart phone could process data with light waves instead of an electrical current, making those devices faster, cheaper and more sustainable through less heat and power consumption? That's just one possibility that could one day result from an international research collaboration that's exploring how to improve the performance of plasmonic devices.
