Vintage illustration astronomy and celestial map by Joseph (James) Moxon (1627-1691). Star chart featuring a world planisphere and celestial sphere - both are surrounded by scenes from the Old and New Testaments including vignettes of the Creation, the Garden of Eden, the Deluge, Moses, the Crucifixion and angels observing the Holy City. Created circa 1691 -1699.

Joseph Moxon was a hydrographer to Charles II, was an English printer of mathematical books and maps, a maker of globes and mathematical instruments, and mathematical lexicographer. Joseph Moxin produced the first English language dictionary devoted to mathematics. In November 1678 he became the first tradesman to be elected as a Fellow of the Royal Society.

Lockheed Martin claims “technological breakthrough” in compact fusion

Science Focus

original post »
Lockheed Martin's promo video for its fusion project.

Reuters is reporting that defense contractor Lockheed Martin claims it has made a technological breakthrough that places us on the doorstep of affordable fusion energy. Supposedly, the breakthrough will result in compact fusion reactors before a decade is out.

But the Lockheed Martin press release that coincides with the coverage says little of the sort. There, the company simply states that after initial work in the area, it expects to be able to build a prototype in five years. If everything goes well, the design could "be developed and deployed in as little as ten years." The "if" in the last sentence, however, is a big one.

The hype also seems to have been designed to leverage a technical article in Aviation Week that goes into some of the details about how Lockheed Martin is structuring its design. The general concept is similar to a Tokamak, in that it involves magnetic confinement of a plasma rather than hitting a small target with massive amounts of laser power. But the shape of the container is different and, according to the company's researchers, more efficient. However, the Aviation Week report also notes, "The team acknowledges that the project is in its earliest stages, and many key challenges remain before a viable prototype can be built."

Wreath Nebula in our awesome Milky Way Sticker

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


tagged with: envelope sealers, star forming activity, wnmwbpt, interstellar gas clouds, milky way, wreath nebula, awesome astronomy images, metallic elements, new born stars, galaxies, dust clouds, star nurseries, young hot stars

Galaxies, Stars and Nebulae series A gorgeous outer space picture featuring the Wreath Nebula, located in our Milky way near the boundary between the constellations of Perseus and Taurus.
Tiny particles of dust, glowing warmly in the energy being radiated by the new-born star are similar to those in the composition of our Earthly smog. The red cloud is cooler than its environs and likely comprises more metallic elements as well.

Melotte 15 in the Heart

more »
Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. About 1.5 million years young, the cluster stars are toward the right in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 30 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Wider field images reveal that IC 1805's simpler, overall outline suggests its popular name - The Heart Nebula. IC 1805 is located about 7,500 light years away toward the boastful constellation Cassiopeia.

Explosion first evidence of a hydrogen-deficient supernova progenitor

more »

A new model is the first characterization of the progenitor for a hydrogen-deficient supernova. The model predicts that a bright hot star, which is the binary companion to an exploding object, remains after the explosion.Their findings have important implications for the evolution of massive stars.

The Crab Nebula from the Hubble Space Telescope Cover For The iPad Mini

Here's a great iPad case from Zazzle featuring a Hubble-related design. Maybe you'd like to see your name on it? Click to personalize and see what it's like!


tagged with: nebula, crab, space, astronomy, hubble, crab nebula, hubble telescope, outer space

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.
