The nuclear age turns 70 today

Science Focus

original post »

Seventy years ago this morning, the world fully entered the nuclear age with the detonation of the first atomic bomb in Alamogordo, New Mexico. The bomb was the product of the Manhattan Project, a top-secret research program tasked with developing a bomb more powerful than any that had come before. The test, called Trinity, happened at 5:30am local time and yielded an explosion equivalent to 20,000 tons of TNT (20kT).

The Manhattan Project, and the earlier UK effort, Tube Alloys, stemmed from pre-World War II physics research that revealed the huge amounts of energy that could be liberated from the fission of uranium atom nuclei, assuming a self-sustaining chain reaction could be started. The bomb used in the Trinity test, called Gadget, used high explosives to compress plutonium into a critical mass. It was the same design used in the bombing of Nagasaki on August 9, 1945; the bomb used on Hiroshima three days earlier was a cruder design.

The first 109 miliseconds of the Trinity test. If these images fill you with a morbid fascination, we highly recommend the book 100 Suns.

Robert Oppenheimer, a physicist chosen to lead the bomb's development, greeted the appearance of a second sun over the desert of New Mexico with a quote from a Hindu scripture, the Bhagavad Gita: "Now I am become Death, the destroyer of worlds."

Name, Cats Eye Nebula, Eye of God outer space Gift Wrap Paper

Get your out-of-this-world gift wrap here! Perfect for Christmas gifts for anyone who is fascinated by what the universe holds in store for us!


tagged with: nebulae, hubble chandra images, cats eye nebula, dying star, red giant evolution, outer space, galaxy stars, tcenebnch, deep space astronomy, eye of god, stellar evolution, nasa

Galaxies, Stars and Nebulae series A gorgeous design featuring a composite image of the Cat's Eye nebula from NASA's Chandra X-ray Observatory and the Hubble Space Telescope.
This famous nebula represents a phase of stellar evolution after a star like our Sun runs out of fuel. In this phase, a star becomes an expanding red giant and sheds some of its outer layers, eventually leaving behind a hot core that collapses to form a dense white dwarf star. A fast wind emanating from the hot core rams into the ejected atmosphere, pushes it outward, and creates the graceful filamentary structures.

Celestial Bauble, Nebula N90 and Pulsar SXP1062 Wrapping Paper

Get your out-of-this-world gift wrap here! Perfect for Christmas gifts for anyone who is fascinated by what the universe holds in store for us!


tagged with: sculptured gas clouds, hot young stars, star galaxies, outer space picture, supernova remnant, star factory, small magellanic cloud, smc, celestial bauble, hrbstslr sxp1062, star incubator

Galaxies, Stars and Nebulae series: In this composite image, X-rays from Chandra and XMM-Newton have been colored blue and optical data from the Cerro Tololo Inter-American Observatory in Chile are colored red and green. The flowering shape is a star factory and the bright blue star is the pulsar, known as SXP 1062. Astronomers are interested in SXP 1062 because it's spinning unusually slowly - about once every 18 minutes. (In contrast, some pulsars are found to revolve up to 1000 times per second)

Merging Galaxies - The Antennae Galaxies Square Sticker

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


tagged with: envelope sealer, stretch frame, awesome astronomy images, super star clusters, agmcssc, antennae galaxies, merging galaxies, star cluster formation, best hubble photos, ngc4038 ngc4039, dust clouds, new born stars

Galaxies, Stars and Nebulae series A stunning outer space picture featuring two merging galaxies, known as the Antennae Galaxies - NGC4038 and NGC4039. As these galaxies hurtle through each other, billions of new stars are forced to precipitate out of the gas and dust clouds by the bunching and heating that's caused by the massive gravitic interactions. These tend to occur in clusters, the brightest and most condensed of them being known as super star clusters.
