This is my current little project I’ve got going on, I have a huge list of scientists of various disciplines I’m slowly getting through and putting up on my Redbubble store. When I’ve finished my list I’ll start making sets to sell, but for now they are just available individually on tshirts.

Hunter Cole - Artist and Geneticist

Cole grows the bacteria in a liquid culture, and then uses the culture as her paint, applying it to a gelatinous augur in a petri dish, as if the augur were a canvas. When applied, the culture is clear, but over a 24 hour period it slowly begins to glow, becoming more visible. For the two weeks following the culture’s application, as the bacteria grows and dies, the drawing changes.

Big Dipper and Magic Telescope

Stars of the constellation Ursa Major (the Big bear) form the familiar dipper-like asterism in the northern sky as photographed from the Roque de los Muchachos Observatory on the Canary island of La Palma.

The starry night sky is reflected from one of a pair of 17 meter diameter, multi-mirrored MAGIC telescopes. The MAGIC (Major Atmospheric Gamma Imaging Cherenkov) telescope is intended to observe gamma rays indirectly by detecting brief flashes of optical light, called -Cherenkov light. — Babak Tafreshi

Damn spaceplasma that’s how you doing it nowadays? Just straight up deleting my url off the posts on my blog so it can source back to you?

Stay classy, brother. Fixed up the source if you don’t mind.

Our Night Sky When We Collide With Andromeda

In the photos above in order:

— Present day
— 2 Billion years from now the of the approaching Andromeda galaxy is noticeably larger
— 3.75 Billion years, Andromeda fills the field of view
— 3.85 Billion years, the sky is ablaze with new star formation
— 3.9 Billion years, star formation continues
— 4 Billion years, Milky Way is warped and Andromeda is tidally stretched
— 5.1 Billion years, cores of both galaxies appear as a pair of globes
— 7 Billion years, the cores have merged, the bright core dominates the night sky

Here is an animation of the collision

In around 4 billion years our galaxy, The Milky Way, will collide with our neighbor galaxy Andromeda or M31. You might think this will be a catastrophic event for everything in the galaxy including our solar system but in reality most of the solar systems will simply pass by each other. However, given the new galactic center and the new mass pulling everything towards it and tossing it around, the orbits of those solar systems will be changed.

The massive Andromeda galaxy is about 120,000 light years across while our galaxy is 100,000 light years across. Given their size, the speed that we our hurdling towards each other is relatively small at 250,000 miles per hour.

Antimatter and Fusion Drives Could Power Future Spaceships

Nuclear fusion reactions sparked by beams of antimatter could be propelling ultra-fast spaceships on long journeys before the end of the century, researchers say.

A fusion-powered spacecraft could reach Jupiter within four months, potentially opening up parts of the outer solar system to manned exploration, according to a 2010 NASA report.

A number of hurdles would have to be overcome—particularly in the production and storage of antimatter—to make the technology feasible, but some experts imagine it could be ready to go in a half-century or so.

It’s “probably not a 40-year technology, but 50, 60? Quite possible, and something that would have a significant impact on exploration by changing the mass-power-finance calculus when planning,” Jason Hay, a senior aerospace technology analyst for consulting firm The Tauri Group, said during an Aug. 29 presentation with NASA’s Future In-Space Operations working group.

The power of fusion

The fuel for such a fusion-driven spaceship would likely consist of many small pellets containing deuterium and tritium—heavy isotopes of hydrogen that harbor one or two neutrons, respectively, in their nuclei. (The common hydrogen atom has no neutrons.)

Inside each pellet, this fuel would be surrounded by another material, perhaps uranium. A beam of antiprotons—the antimatter equivalent of protons, sporting a net electrical charge of minus-1 rather than plus-1—would be directed at the pellets.

When the antiprotons slammed into uranium nuclei, they would annihilate, generating high-energy fission products that ignite fusion reactions in the fuel.

Such reactions—for example, deuterium and tritium nuclei merging to create one helium-4 atom and one neutron—throw off huge amounts of energy that could be harnessed to propel a spacecraft in several different ways.

“The energy from these reactions could be used to heat a propellant or provide thrust through magnetic confinement and a magnetic nozzle,” states the 2010 report, called “Technology Frontiers: Breakthrough Capabilities for Space Exploration,” which NASA produced with the help of The Tauri Group and other experts.

The basic idea is not new: Project Daedalus, a study conducted by the British Interplanetary Society in the 1970s, proposed using a fusion rocket to power an interstellar spacecraft. Daedalus’ fusion reactions would be sparked by electron beams rather than antiproton beams, however.

Nuclear Propulsion Through Direct Conversion of Fusion Energy

The future of manned space exploration and development of space depends critically on the creation of a vastly more efficient propulsion architecture for in-space transportation.

Nuclear-powered rockets can provide the large energy density gain required. A small scale, low cost path to fusion-based propulsion is to be investigated. It is accomplished by employing the propellant to compress and heat a magnetized plasma to fusion conditions, and thereby channel the fusion energy released into heating only the propellant.

Passage of the hot propellant through a magnetic nozzle rapidly converts this thermal energy into both directed (propulsive) energy and electrical energy.
