| Hubble's Cosmic Origins Spectrograph. | Spectroscopes or spectrographs are absolutely essential in that toolbox of astronomical tools that are so important for research. They produce ugly pictures. But they are the nuts and bolts of physical science. They put the physics in astrophysics.
If you look out across the universe today and you start seeing this inhomogeneous web-like structure with filaments, places where filaments come together, looks just like a big three-dimensional spider web, tracing all those filaments is the light of ordinary stars and galaxies.

| Hubble COS Instrument | The Cosmic Origins Spectrograph (COS) is designed to study the large-scale structure of the universe and how galaxies, stars and planets formed and evolved. It will help determine how elements needed for life such as carbon and iron first formed and how their abundances have increased over the lifetime of the universe.
As a spectrograph, COS wont capture the majestic visual images that Hubble is known for, but rather it will perform spectroscopy, the science of breaking up light into its individual components. Any object that absorbs or emits light can be studied with a spectrograph to determine its temperature, density, chemical composition and velocity.
A primary science objective for COS is to measure the structure and composition of the ordinary matter that is concentrated in what scientists call the cosmic web—long, narrow filaments of galaxies and intergalactic gas separated by huge voids. The cosmic web is shaped by the gravity of the mysterious, underlying cold dark matter, while ordinary matter serves as a luminous tracery of the filaments. COS will use scores of faint distant quasars as cosmic flashlights, whose beams of light have passed through the cosmic web. Absorption of this light by material in the web will reveal the characteristic spectral fingerprints of that material. This will allow Hubble observers to deduce its composition and its specific location in space.
COS has two channels, the Far Ultraviolet (FUV) channel covering wavelengths from 115 to 177 nm, and the Near Ultraviolet (NUV) channel, covering 175-300 nm. Ultraviolet light, the type of radiation that causes sunburn, is more energetic than visible, optical light; and near UV refers to the part of the UV spectrum closer to the visible, just beyond the color violet.
The light-sensing detectors of both channels are designed around thin micro-channel plates comprising thousands of tiny curved glass tubes, all aligned in the same direction. Simply described, incoming photons of light ultimately induce showers of electrons to be emitted from the walls of these tubes. The electron showers are accelerated, captured, and counted in electronic circuitry immediately behind the micro-channel plates.
A key feature of COS—the one which makes it unique among Hubble spectrographs—is its maximized efficiency, or throughput. Each bounce of a light beam off an optical surface within an instrument takes some of the light away from the beam, reducing the throughput. This is a problem that is especially acute in the UV, and the COS FUV channel was designed specifically to minimize the number of light bounces. The incoming FUV beam makes one bounce off a selectable light-dispersing grating, and goes directly to the detector. An additional advantage within COS is the very low level of scattered light produced by its light-dispersing gratings.
If astronauts are able to complete the on-orbit repair of the Space Telescope Imaging Spectrograph (STIS) aboard Hubble, it will highly complement the COS. The all purpose STIS, installed in 1997 during Servicing Mission 2, suffered an electronics failure in 2004 and is currently in safe hold. By design, the COS does not duplicate all of STISs capabilities. Possessing more than 30 times the sensitivity of STIS for FUV observations of faint objects such as distant quasars, COS will enable key scientific programs which would not be possible using STIS. On the other hand, COS is best suited to observing point sources of light such as stars and quasars, while STIS has the unique ability to observe the spectrum of light across spatially extended objects such as galaxies and nebulae. Should STIS be repaired, the two spectrographs working in tandem will provide astronomers with a full set of spectroscopic tools for astrophysical research.
COS will be installed in the instrument bay currently occupied by COSTAR, the set of corrector mirrors on deployable arms that provided corrected light beams to the first generation of Hubble instruments after SM1 in 1993. Astronauts will store the no longer needed COSTAR instrument aboard the shuttle for its return to Earth. |  |

| Stellar Data on Enceladus' Plume | New structure, density and composition measurements of Enceladus' water plume were obtained when the Cassini spacecraft's Ultraviolet Imaging Spectrograph observed the star zeta Orionis pass behind the plume Oct. 24, 2007, as seen in this animation.
Changes in the starlight as it dimmed while passing through the plume allowed the spectrograph to identify the plume's physical and chemical composition. The spectrograph detected four high-density gas streams composed of water vapor. The density of the water vapor is twice that of the broad plume of gas that surrounds each jet.
This measurement confirms the theoretical analysis performed prior to the flyby that showed it was safe for Cassini to fly very closely past Enceladus, even through part of the plume, during the March 12, 2008 flyby.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency to study Saturn and it's moons. |  |
| Lena's face in sound | http://photosounder.com
In this video we use Photosounder to 'embed' an image into sound, and then use the program Spectrogram 16 to reveal the image as it is contained in that sound.
To reproduce this, set the Frequency scale knob to LINEAR (1.00), choose your frequency range and tweak the Time resolution knob to choose the duration of the resulting sound. Note that the largest you make the sound duration be the nicer and less noisy the resulting image will be. You can then use any other spectrograph program to reveal the image. |  |
| "The Presence" | "The Presence" is an icon frequently appearing in many forms of media surrounding Nine Inch Nails' new album, "Year Zero."
When you play the LEAKED VERSION of "My Violent Heart" or the ALBUM VERSION of "The Warning" through a spectrograph, the static at the very end of the song produces an image of The Presence.
For those interested, this is how I was able to see The Presence myself:
1. Open WinAmp, load the LEAKED VERSION of "My Violent Heart" or the ALBUM VERSION of "The Warning," whichever is applicable (see above).
2. Right-click on WinAmp.
3. In the menu that appears, select "Visualization," then select "Select plug-in..." The Visualization Plug-ins menu should appear.
4. Left-click "Nullsoft Tiny Fullscreen (v2.08) [vis_nsfs.dll]."
5. Under "Plug-in Module" towards the bottom of the screen, select "Sexy Scrolling Voiceprint" from the drop-down menu.
6. Play the song (you can do it without having to close the "Visualization Plug-in" menu).
7. As the song is playing, click "Start" in the "Visualization Plug-In" menu.
8. The Presence will appear during the static at the END of the song.
How does this work? The spectrograph is, in a nutshell, the visual representation of low to high frequency sounds. The louder the sound, the brighter the visual representation. In most spectrographs, the highest frequencies are at the top of the screen, the lowest are at the bottom. Everything in between is high (top) to low (bottom).
For instance, a hi-hat sound will appear mostly from the middle to near the top of the screen. A bass drum sound will be more towards the bottom of the screen.
The image of The Presence is produced in a very creative fashion. Low to high levels of noise frequency (what your ear hears as "static") paint the entire screen with many, many bright colors. You'll notice that there's a brief break between two hits of static. This is the "arm" of The Presence. Since there is no sound during this time, the spectrograph produces no visuals. Thusly, it looks like a dark "arm" of The Presence.
The break of the lower-frequency noises is much more difficult to hear, especially since it begins as much of the high-frequency static remains. However, during the higher-frequency break, you can actually hear two of the low frequency hits.
The fingers are produced by cutting off low-frequency noises several times in the same manner as the arm is created by cutting off high frequency noise. Each cut-off of low-frequency noise produces a "finger" of The Presence. There is debate as to how many fingers The Presence actually has. This video proves there ARE actually five, not four.
As the "break" in higher-frequency noise cuts out (drawing The Presence's "arm"), you can hear a couple very low frequency static hits if you listen very, very closely.
Aphex Twin's "Windowlicker" is another song that produces an image when played through a spectrograph. However, the image will only appear while using the CD or a very high quality MP3. Lower quality recordings do not produce the image. |  |

| Exploring Physics Across the Universe | The Cosmic Origins Spectrograph (COS) is a new instrument developed for the Hubble Space Telescope planned for installation during the next shuttle mission to the Hubble (SM4) in 2008. It is designed for high throughput, medium resolution (R=20,000) spectroscopy of point sources, allowing the efficient observation of numerous faint extragalactic and galactic ultraviolet (1150-3000 A) targets. The primary science objectives of the mission are the study of the origins of large-scale structure in the universe, the formation and evolution of galaxies, and the origin of stellar and planetary systems and the cold interstellar medium. The instrument has been designed with maximum effective area as the primary constraint, and will provide more than an order of magnitude gain in sensitivity over previous HST instruments in this wavelength region. |  |

| Acid Glitch | A quick experiment with converting image to audio, trying to understand the techniques used on Aphex Twins 'Equation' and Venetian Snares' 'Look'. Admittedly it sounds terrible but it was interesting to see how certain effects altered the image.
The main effects used were Re-Trigger and Tape Stop. The Tape Stop effect managed to make the image appear to 'melt' at the end as the pitch of the sample decreased. The frequency scale was set to logarithmic, but I found that linear in most cases worked even better.
The screen capture does stutter but it was recording at its highest quality and that was the best result so suggestions for quality Screen Capture software are welcome. |  |

| God does not Exist | http://www.strike-the-root.com/71/molyneux/molyneux1.html
Existence is a relatively simple concept -- it is defined as that which consists of either matter or energy. Therefore if a god exists, it must be composed of either matter or energy.
The opposite must also be true. If a god is not composed of matter or energy, then that god, by definition, does not exist. Thus to argue that a god exist, despite a total absence of matter or energy, is to argue, existence equals non-existence, which is a complete contradiction.
If a god exists, then physical evidence is really the only methodology by which we can ascertain that a god exists. Of course, this does not require direct physical evidence -- we cannot perceive black holes directly, but we know that they exist due to the effects of their gravity wells on surrounding matter, as well as the flashes of energy that are released as captured matter crosses the event horizon. But since "existence" is defined as that which is composed of matter or energy, the proof of existence must be some evidence of that matter or energy.
Evidence is defined as that which impacts our physical senses in some manner, either directly, or through some translating device such as a spectrograph or an oscilloscope. Since our sensory organs are designed to perceive the effects of matter and energy, it is through the evidence of the senses that we can determine the existence or nonexistence of things.
If I argue that something exists, but then claim there is no way to detect it, my argument contradicts itself. Let's say I tell a deaf man that I hear a deep, loud sound coming from a speaker. If he lays his hand on it and feels no vibrations, he has every right to be skeptical. If I say that this loud sound does not have vibrations, he may then pull out his trusty microphone or other sound wave detector. If this instrument detects no sound in the vicinity, can I still tell him that this loud sound is occurring? At some point, if my definition of "loud sound" basically boils down to "that which is the opposite of any evidence that a loud sound is occurring," then clearly my approach to truth needs a little work.
This approach helps clarify the truth value of the proposition that a god does not exist. If a god exists, then sensual evidence of some sort is required to determine the existence of that god. If a god is not made up of matter or energy, then that god does not exist, since that which is not composed of matter or energy -- does not exist.
If a god is made up of matter and energy, then it is subject to physical laws. Since it is bound by physical laws, miracles are impossible, because miracles are, by definition, violations of physical laws. Likewise, a god cannot be all knowing and all-powerful, since both attributes would violate the basic tenets of physical laws. All knowing would require instantaneous knowledge of all matter, past, present and future, which is clearly impossible, while all powerful would require the ability to break the bounds of physical laws, which brings us back to the realm of nonexistence.
If a god is subject to physical laws, then praying to a god makes about as much sense as worshiping a black hole, begging the Sun to grant you favors, or circumcising your son to appease the moon. If a god is not subject to physical laws, then the concept of a god is synonymous with the concept of non-existence.
Why is there such resistance to the fact that a god does not exist? Many people redefine "God" within their own minds as "a potential form of matter or energy that has not been discovered yet," or "that which could exist in an alternate universe," or something to that effect.
However, either a criterion for determining truth exists, or it does not. If such a criterion exists, then it must be objective, and based on the evidence of the senses and reason, which precludes the existence of any deities. If no such criterion exists, then both everything and nothing is true, and agnosticism, atheism, superstition, religion and the belief of the flying spaghetti monster are all equally valid.
If an objective criterion for truth exists, then it cannot logically be applied according to whim, or only in situations that feel emotionally comfortable. Through this logical method we can determine no god exists.
Actions are more important than beliefs. |  |

| NEAR - Near Earth Asteroid Rendezvous | The Near Earth Asteroid Rendezvous - Shoemaker (NEAR Shoemaker), renamed after its launch in honor of planetary scientist Eugene M. Shoemaker, is a robotic space probe designed to study the near-Earth asteroid Eros from close orbit over a period of a year. The primary scientific objective of NEAR was to return data on the bulk properties, composition, mineralogy, morphology, internal mass distribution and magnetic field of Eros. Secondary objectives include studies of regolith properties, interactions with the solar wind, possible current activity as indicated by dust or gas, and the asteroid spin state. This data will be used to help understand the characteristics of asteroids in general, their relationship to meteorites and comets, and the conditions in the early solar system. To accomplish these goals, the spacecraft was equipped with an X-ray/gamma ray spectrometer, a near-infrared imaging spectrograph, a multi-spectral camera fitted with a CCD imaging detector, a laser rangefinder, and a magnetometer. A radio science experiment was also performed using the NEAR tracking system to estimate the gravity field of the asteroid. The total mass of the instruments was 56 kg, and they required 81 W power. |  |

| Cigar Galaxy Up In Smoke | This movie compares a visible-light view of the "Cigar galaxy" to an infrared view from NASA's Spitzer Space Telescope of the same galaxy. The movie begins with the visible image of the galaxy looking cool as a cucumber, then fades into the infrared image, revealing a smokin' hot "cigar."
The visible-light picture of the Cigar galaxy, also called Messier 82, shows only a bar of light against a dark patch of space. Longer exposures of the galaxy (not pictured here) have revealed cone-shaped clouds of hot gas above and below the galaxy's plane. It took Spitzer's three sensitive instruments to show that the galaxy is also surrounded by a huge, hidden halo of smoky dust (red in infrared image).
The infrared image above was taken by Spitzer's infrared array camera. The dust particles (red) are being blown out into space by the galaxy's hot stars (blue).
Spitzer's infrared spectrograph told astronomers that the dust contains a carbon-containing compound, called polycyclic aromatic hydrocarbon. This smelly molecule can be found on Earth in tailpipes, barbecue pits and other places where combustion reactions have occurred.
Messier 82 is located about 12 million light-years away in the Ursa Major constellation. It is viewed from its side, or edge on, so it appears as a thin cigar-shaped bar. The galaxy is termed a starburst because its core is a fiery hotbed of stellar birth. A larger nearby galaxy, called Messier 81, is gravitationally interacting with Messier 82, prodding it into producing the new stars.
The infrared picture was taken as a part of the Spitzer Infrared Nearby Galaxy Survey. Blue indicates infrared light of 3.6 microns, green corresponds to 4.5 microns, and red to 5.8 and 8.0 microns. The contribution from starlight (measured at 3.6 microns) has been subtracted from the 5.8- and 8-micron images to enhance the visibility of the dust features.
The visible-light picture is from the National Optical Astronomy Observatory, Tucson, Ariz.

| Icy Organics in Planet-Forming Discs | Using the Spitzer Space Telescope, astronomers are probing the chemistry of circumstellar discs, the dusty discs that surround stars, to understand the first moments in planetary life. Spitzer has turned its ultra-sensitive infrared spectrograph instrument toward five young stars in the constellation Taurus. These stars are still surrounded by thick, dusty discs -- relics of the gravitational collapse that formed them only a few million years ago. The five discs have similar chemistry, indicating dusty material rich in silicates and organic compounds, as well as both water and carbon dioxide ices. Despite their similarities, there are also intriguing differences between the discs that may hold important clues about the evolution of stars and their young planetary systems.
In this animation, we focus on the disc of a young star. Light from the star is almost completely blocked by the thick dust and is seen only when it scatters off dust and gas above the disc plane. Delving in closer, we observe that the disc is composed of countless tiny grains of dust, some of which, according to Spitzer observations, have crystal structures. These dust grains may serve as the first building blocks of new planets, accreting into larger and larger bodies, as time progresses.
As a few of these crystals fill our view, a strange metamorphosis takes place. Ice, already known to be present in these discs, begins to condense onto the surface of the crystals. Over time, the grains become larger, icier and more spherical. These chemical and physical changes in the dust grains may explain the differing spectral characteristics of the discs, and may also serve as a marker of the age and evolutionary stage of protoplanetary, or planet-forming, discs. |  |
