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. The orange filaments are the tattered remains of the star and consist mostly of hydrogen. The rapidly spinning neutron star embedded in the center of the nebula is the dynamo powering the nebula's eerie interior bluish glow. The blue light comes from electrons whirling at nearly the speed of light around magnetic field lines from the neutron star. The neutron star, like a lighthouse, ejects twin beams of radiation that appear to pulse 30 times a second due to the neutron star's rotation. A neutron star is the crushed ultra-dense core of the exploded star. The Crab Nebula derived its name from its appearance in a drawing made by Irish astronomer Lord Rosse in 1844, using a 36-inch telescope. When viewed by Hubble, as well as by large ground-based telescopes such as the European Southern Observatory's Very Large Telescope, the Crab Nebula takes on a more detailed appearance that yields clues into the spectacular demise of a star, 6,500 light-years away. The newly composed image was assembled from 24 individual Wide Field and Planetary Camera 2 exposures taken in October 1999, January 2000, and December 2000. The colors in the image indicate the different elements that were expelled during the explosion. Blue in the filaments in the outer part of the nebula represents neutral oxygen, green is singly-ionized sulfur, and red indicates doubly-ionized oxygen.

Curiosity catches a whiff of methane on Mars -- and a possibility of past life

Science Focus

original post »


NASA has revealed that a whiff of methane has been detected twice in the last couple of years at the Martian surface by the Curiosity Rover.

The source of the methane is uncertain. It is not even clear if the methane originated on Mars or arrived there by way of a meteorite that landed on the surface of the red planet, but this is the strongest evidence yet of possible life in its ancient past.

"We have full confidence that there is methane in the atmosphere of Mars," announced John Grotzinger of CalTech, a Curiosity project scientist, on December 16. "Life is one of the few hypotheses for...

NASA just e-mailed a wrench to space

Science Focus

original post »

When International Space Station Commander Barry Wilmore needed a wrench, NASA knew just what to do. They "e-mailed" him one. This is the first time an object has been designed on Earth and then transmitted to space for manufacture.

Made In Space, the California company that designed the 3D printer aboard the ISS, overheard Wilmore mentioning the need for a ratcheting socket wrench and decided to create one. Previously, if an astronaut needed a specific tool it would have to be flown up on the next mission to the ISS, which could take months.

This isn't the first 3D-printed object made in space, but it is the first created to meet the needs of an astronaut. In November astronauts aboard the ISS printed a replacement part for the recently installed 3D printer. A total of 21 objects have now been printed in space, all of which will be brought back to Earth for testing.

Apollo 11 Landing Site Panorama

more »
Have you seen a panorama from another world lately? Assembled from high-resolution scans of the original film frames, this one sweeps across the magnificent desolation of the Apollo 11 landing site on the Moon's Sea of Tranquility. Taken by Neil Armstrong looking out his window of the Eagle Lunar Module, the frame at the far left (AS11-37-5449) is the first picture taken by a person on another world. Toward the south, thruster nozzles can be seen in the foreground on the left, while at the right, the shadow of the Eagle is visible toward the west. For scale, the large, shallow crater on the right has a diameter of about 12 meters. Frames taken from the Lunar Module windows about an hour and a half after landing, before walking on the lunar surface, were intended to initially document the landing site in case an early departure was necessary.

Carina Nebula, Star Forming Gas-cloud Sculpture Stickers

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


tagged with: billowing interstellar gas clouds, cnbigc, star forming activity, carina nebula, amazing space sculpture, star nurseries, stellar winds, young hot stars, gas cloud sculpture

Galaxies, Stars and Nebulae series A beautiful space photograph featuring the 7500 light year distant Carina Nebula. This Hubble image shows rich, interstellar gas clouds feeding the formation of new stars. As a proto star forms, the gas clouds get dragged to its surface and some gets emitted as tight jets of material travelling at hundreds of miles per second. These in turn help sculpt the gas clouds into weird and grotesque shapes, some looking like strange worms, swimming through space.

tagged with: v838, monocerotis, hubble, astronomy, space, hubble space telescope, nasa, light echo

In January 2002, a dull star in an obscure constellation suddenly became 600,000 times more luminous than our Sun, temporarily making it the brightest star in our Milky Way galaxy. The mysterious star, called V838 Monocerotis, has long since faded back to obscurity. But observations by NASA&#39;s Hubble Space Telescope of a phenomenon called a "light echo" around the star have uncovered remarkable new features. These details promise to provide astronomers with a CAT-scan-like probe of the three-dimensional structure of shells of dust surrounding an aging star.

Tarantula Nebula Star Forming Gas Cloud Sculpture Star Sticker

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


tagged with: envelope sealers, tnlmcsfr, billowing interstellar gas clouds, awesome hubble images, tarantula nebula, large magellanic cloud, star forming activity, young hot stars, star nurseries, triggering star formation

Galaxies, Stars and Nebulae series An awesome mobile phone shell featuring the Tarantula Nebula of the Large Magellanic Cloud, which is the nearest galaxy to the Milky Way, our galactic home. This Hubble image shows old stars from the distant past and rich, interstellar gas clouds feeding the formation of new ones. The most massive and hottest stars are intense, high-energy radiation sources and this pushes away what remains of the gas and dust, compressing and sculpting it. As the whorls and eddies clump and stretch it, gravity takes over and the birth of the next generation of new stars is triggered.

Horsehead Nebula Room Decal

Here's a great wall decal featuring a beautiful image from deep space


tagged with: horsehead nebula, dark nebula, nebulae, space, astronomy, space exploration, universe, cosmic, milky way galaxy, outer space

A reproduction of a composite colour image of the Horsehead Nebula (also known as Barnard 33 in emission nebula IC 434) and its immediate surroundings. It's based on three exposures in the visual part of the spectrum with the FORS2 multi-mode instrument at the 8.2-m KUEYEN telescope at Paranal. The Horsehead Nebula is a dark nebula in the constellation Orion. The nebula is located just to the south of the star Alnitak, which is farthest west on Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. The nebula was first recorded in 1888 by Williamina Fleming.
