Biggest explosions in the universe powered by strongest magnets

more »
Observations have for the first time demonstrated a link between a very long-lasting burst of gamma rays and an unusually bright supernova explosion. The results show that the supernova was not driven by radioactive decay, as expected, but was instead powered by the decaying super-strong magnetic fields around an exotic object called a magnetar.

A cool way to form 2-D conducting polymers using ice

more »
Chemists have discovered an innovative method to form two-dimensional polyaniline (PANI) nanosheets using ice as a hard template. The product, called PANI-ICE, is reported to have distinctly outstanding electrical properties of low resistivity and high conductivity. PANI-ICE nanosheets show high electronic current flows twice as high as that of graphene and over 40 times higher conductivity of PANI materials produced by existing established synthetic procedures.

Biggest explosions in the universe powered by strongest magnets

Observations from ESO's La Silla and Paranal Observatories in Chile have for the first time demonstrated a link between a very long-lasting burst of gamma rays and an unusually bright supernova explosion. The results show that the supernova was not driven by radioactive decay, as expected, but was instead powered by the decaying super-strong magnetic fields around an exotic object called a magnetar. The results will appear in the journal Nature on July 9, 2015.

Searing sun seen in X-rays

more »
X-rays light up the surface of our Sun in a bouquet of colors in this new image. The high-energy X-rays seen by NuSTAR are shown in blue, while green represents lower-energy X-rays from the X-ray Telescope instrument on the Hinode spacecraft, named after the Japanese word for sunrise.

A black hole under the gravitational lens

more »
Turbulent processes take place close to supermassive black holes, which lurk in the centers of nearly all galaxies. They swallow up matter flowing in from the outside while at the same time producing so-called gas jets which shoot out into space in two opposite directions. Researchers have now succeeded in localizing the origin of the high-energy gamma radiation in such a jet: it apparently originates very close to the black hole. This discovery was made possible by a micro-gravitational lens effect that occurs by chance and selectively amplifies the light from different regions close to the black hole like a magnifying glass. An unusual observation method uncovers processes near the event horizon of a distant, massive monster.

Magnetic storms and green skies on St Patrick’s Day: No problems for power grid

more »
On Saint Patrick’s Day (17 March) the northern lights danced a lively green jig across the skies of Ireland and Britain. The source of these magnetic storms was not just one but two huge eruptions of electrically charged material from the Sun, which traveled through space at millions of kilometers an hour, colliding with the Earth’s magnetic field.

The Active Cigar Galaxy - Messier 82 Square Sticker

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


tagged with: stars, galaxies, outer space, envelope sealers, agmet, galaxies and stars, hubble, chandra, messier 82, cigar galaxy, active galaxies

Galaxies, Stars and Nebulae series

Composite of images of the active galaxy Messier 82 from the three Great Observatories: Hubble Space Telescope, Chandra X-Ray Observatory, and Spitzer Space Telescope. X-ray data recorded by Chandra appears here in blue, infrared light recorded by Spitzer appears in red. Hubble's observation of hydrogen emission appears in orange. Hubble's bluest observation appears in yellow-green.

Ultra-thin, all-inorganic molecular nanowires successfully compounded

more »
The development of metal oxide-based molecular wires is important for fundamental research and potential practical applications. However, examples of these materials are rare. Researchers from Hokkaido University, Kanagawa University, Hiroshima University and Japan Synchrotron Radiation Research Institute/SPring-8, Japan, successfully created ultrathin all-inorganic molecular nanowires, composed of a repeating hexagonal molecular unit made of Mo and Te; the diameters of these wires were only 1.2 nm.

The dark side of galactic radio jets

more »
Cosmic microwave radiation points to invisible 'dark matter', marking the spot where jets of material travel at near light speed, according to an international team of astronomers. Lead author Rupert Allison of Oxford University presented their results yesterday (6 July) at the National Astronomy Meeting in Venue Cymru, Llandudno, Wales.

Eyeing up Earth-like planets

more »
Almost 2000 exoplanets have been discovered to date, ranging from rocky Earth-like planets to hot-Jupiters, and orbiting every type of star. But how many of these distant worlds are habitable? Today’s technology means that we currently have very little information about what exoplanets are like beyond their presence, size and distance from star. With the launch of the James Webb Space Telescope we may have our first glimpses into atmospheres of Earth-like exoplanets.
