Meteors and Milky Way over Mount Ranier : Despite appearances, the sky is not falling. Two weeks ago, however, tiny bits of comet dust were. Featured here is the Perseids meteor shower as captured over Mt. Rainier, Washington, USA. The image was created from a two-hour time lapse video, snaring over 20 meteors, including one that brightened dramatically on the image left. Although each meteor train typically lasts less than a second, the camera was able to capture their color progressions as they disintegrated in the Earths atmosphere. Here an initial green tint may be indicative of small amounts of glowing magnesium atoms that were knocked off the meteor by atoms in the Earths atmosphere. To cap things off, the central band of our Milky Way Galaxy was simultaneously photographed rising straight up behind the snow-covered peak of Mt. Rainier. Another good meteor shower is expected in mid-November when debris from a different comet intersects Earth as the Leonids. via NASA
Here is a blue Tritium stick sealed in another glass vial secured in silver tone “window” setting. Tritium sticks will glow for 10 to 15 years without the need of “charging” like regular glow in the dark pigment powders. It is currently used in high-end watches, keyrings and gun sights - anything that needs to be seen at night. I decided to go with silver tone components because it complements the blow glow. Just as important as the Tritium is the mechanical looking part it’s hanging from. I was attempting to evoke a geared mechanical pulley assemblage with components found in the hardware store mixed with traditional jewellery findings.
I make in the steampunk genre but I wouldn’t classified as steampunk. To me it’s futuristic with an alien artefact feel to it. If you are interested in buying this you can find it on ebay here.
Simeis 147: Supernova Remnant : Its easy to get lost following the intricate strands of the Spaghetti Nebula. A supernova remnant cataloged as Simeis 147 and Sh2-240, the glowing gas filaments cover nearly 3 degrees 6 full moons on the sky. Thats about 150 light-years at the stellar debris clouds estimated distance of 3,000 light-years. This sharp composite includes image data taken through a narrow-band filter to highlight emission from hydrogen atoms tracing the shocked, glowing gas. The supernova remnant has an estimated age of about 40,000 years, meaning light from the massive stellar explosion first reached Earth about 40,000 years ago. But the expanding remnant is not the only aftermath. The cosmic catastrophe also left behind a spinning neutron star or pulsar, all that remains of the original stars core. via NASA
For some reason this reminds me of the old visible petrol pump. This was meant to be housed under a glass dome but the design ended up being too tall for it to fit. So here it is as a pendant. You can see I’ve included a tiny “gauge” including a tiny watch hand. I recently started using hand UV glue which I’ve used to seal the dial. The core is green Tritium with a fine wire spring sealed inside a second glass vial. Tritium glows continuously for 10 to 12 years. Unlike conventional glow in the dark, it doesn’t require “charging” from another light source. The core sits on a heavy solid brass bead. It’s on a brass faceted cut chain that is 22 ½ inches long with a lobster claw clasp. The pendant is 1 ½ inches high and ½ an inch wide.

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 scattered 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 15 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.
Some part of our being knows this is where we came from. We long to return. And we can. Because the cosmos is also within us. We’re made of star stuff. We are a way for the cosmos to know itself. ~ Carl Sagan
Photograph caption dated May 5, 1955 reads, “Early risers were a bit disappointed this morning when they went to roof of a downtown Los Angeles building to see the flash from the big atomic blast in Nevada. Because of heavy layer of clouds between here and there, they saw only a faint glimmer. Blast was at 5:10 a.m.”

In this article, we will be discussing Genesect, the legendary steel bug pokemon. Team Plasma revived Genesect from a fossil, and decided the only way to make this prehistoric bug pokemon cooler was to strap a giant laser cannon to its back. When different drives are equipped, the cannon attached to its back can fire a variety of different types and colors of lasers. For example, the burn drive fires a red laser that is fire-type, and the Shock Drive fires a yellow laser that does electric-type damage. Different colors are created by different wavelengths of light, but how does a laser work?
In basic chemistry, you know that electrons orbit the nucleus of an atom in specific shells, or energy levels. When you give an electron energy, typically by absorbing a photon, the electron will jump from a lower shell to an higher shell, called an excited state. If you excite it with too much energy, the electron leaves the atom entirely. But if the electron is still bound to the atom, it will eventually de-excite and go back to ground state. To do this, it must release some of its excess energy, which it does by creating a photon. The amount of energy that it gives off determines the wavelength, and therefore color, of the light. Purple photons have higher energy than red photons.
This is the same atomic process that glow in the dark toys and many other things use to emit light. What makes lasers different is that this light is then focused. A typical laser consists of several parts: a flash lamp, a medium to excite, a reflector, and an output coupler. The medium determines the color of light. For example, many green lasers use Helium-Neon gas as the medium to produce green light. The first ever laser used ruby, and emitted red light. This is where Genesect’s drives come in. Different drives produce different colors and types of attack, so therefore the different drives represent different mediums.
(From top to bottom: InGaAlP (first two), HeNe, DPSS, and InGaN (bottom two) lasers)
The flash lamp is used to give the medium the initial energy it needs, exciting the electrons inside the medium. The electrons will release photons through the emission process discussed above, and that will start a chain reaction, causing other photons of the exact same properties (same direction, wavelength, frequency, photon energy, polarization) to be emitted while the flash lamp is being pulsed. More and more photons team up together in this way, amplifying the total signal.

The reflector and the output coupler are on opposite sides of the laser. The reflector, as you might have guessed, simply reflects the photons towards the output coupler. Every single photon reflects off of the reflector: it is 100% reflective. The output coupler is what focuses the beam itself. It is not as reflective, and only allows a portion of the photons to be escape in one direction: a beam. The photons that do not escape bounce back to the reflector, and keep going back and forth until they do manage to escape in the right direction allowed by the output coupler, creating a single focused beam of light.
Lasers have tons of applications, including surgery, dentistry, targeting and radar systems, astronomy, laser printers, acne treatment, fingerprint scanners, thermometers, and metal cutting. Metal-cutting lasers actually heat up and melt the metal in a very focused line, to cut it.
Larger destructive weaponized lasers like Genesect’s canon are largely still in development, but they work in similar ways. However, instead of a steady beam of laser, it emits in very fast pulses. The repetitive rapid change between laser and no laser, heat and cool, evaporation and expansion creates a shockwave throughout the target, ultimately damaging them.
Genesect’s laser canon excites electrons in different mediums that emit light, depending on which drive is installed. The light is then reflected and bounced around inside the canon, allowing the light to escape in only one direction, creating a damaging beam.
This is a strong masculine design - something that I want to do more of for my steampunk brothers. It will also appeal to those who like apocalyptic/atomic punk genres with that unusual silver tone pendulum alluding to the motifs of that era.
