NASA Space Telescopes See Weather Patterns in Brown Dwarf

NASA Space Telescopes See Weather Patterns in Brown Dwarf
nasa

Image by NASA Goddard Photo and Video
JANUARY 8, 2013: Astronomers using NASA’s Hubble and Spitzer space telescopes have probed the stormy atmosphere of a brown dwarf named 2MASSJ22282889-431026, creating the most detailed "weather map" yet for this class of cool, star-like orbs. The forecast shows wind-driven, planet-sized clouds enshrouding these strange worlds. Brown dwarfs form out of condensing gas, as stars do, but lack the mass to fuse atoms and produce energy. Instead, these objects, which some call failed stars, are more similar to gas planets with their complex, varied atmospheres. The new research is a stepping stone toward a better understanding not only brown dwarfs, but also of the atmospheres of planets beyond our solar system.

Hubble and Spitzer simultaneously watched the brown dwarf as its light varied in time, brightening and dimming about every 90 minutes as the body rotated. Astronomers found the timing of this change in brightness depended on whether they looked using different wavelengths of infrared light. The variations are the result of different layers or patches of material swirling around in the brown dwarf in windy storms as large as Earth itself. Spitzer and Hubble see different atmospheric layers because certain infrared wavelengths are blocked by vapors of water and methane high up, while other infrared wavelengths emerge from much deeper layers. Daniel Apai, the principal investigator of the research from the University of Arizona, Tucson, presented the results at the American Astronomical Society meeting on January 8 in Long Beach, Calif. A study describing the results, led by Esther Buenzli, also of the University of Arizona, is published in the Astrophysical Journal Letters.

The Shuttle Carrier Aircraft 747 that will piggyback Atlantis to Kennedy Space Center bathes in the light of a desert sunrise, awaiting take-off from Biggs Army Air Field at El Paso. The ferry flight is heading to Kelly Field at Lackland, near San Antonio, Texas. It should get in there at about 9:00 local time. (Yep, Texas is really so big that they need two stops to get across it.) It will refuel and then continue on to Columbus Air Force Base in Columbus, Mississippi.

Radioactive

Living with Radiation: The First Hundred Years

In the century since radioactivity was discovered, radioactive substances have been used extensively for a number of applications. Especially in the early part of the 20th century, and to a lesser extent today, a number of commonly available products have been radioactive. These include:
* luminous watch dials (radium and tritium)
* orange ceramicware (notably Fiestaware from the 40s and 50s; uranium oxide)
* smoke detectors (americium 241; in current use)
* gas camping lantern mantles (thorium; some manufacturers no longer use this)
* camera lenses (thorium)
* static eliminators for film and records (polonium 210)
* welding rods and arc lamps (thorium)
* vacuum tubes (thorium was used to increase electron emission)
A fascinating look at the proliferation of uses of radioactive materials in the last century can be found in the book “Living with Radiation: The First Hundred Years” by Paul Frame and William Kolb. It tells the story of the use of radioactive materials in consumer and commercial products in the century since radioactivity was discovered. Second edition: copyright William M. Kolb and Paul Frame, 2000. 256 pages, numerous photographs.
Depleted Uranium – Half Fuel Pellet

The nuclear fuel is slightly enriched uranium (2%) in the form of uranium dioxide. This is a chemically-stable and heat-resistant ceramic material. It is prepared in powdered form, pressed into small, 11 5 mm diameter and 15 mm long pellets and sintered in the presence of a binder. The pellet shape is adapted to an intensive, high-temperature operating mode. For example, the pellets have hemispherical indentations, in order to reduce the fuel column’s thermal expansion and thermo-mechanical interaction with the cladding. One uranium nuclear fuel pellet the size of the tip of a little finger is equivalent to the energy provided by 1,780 pounds of coal; or 149 gallons of oil, as much oil as fits in three 50 gallon drums; or 17,000 cubic feet of natural gas. The energy is released inside the reactor through fission—the splitting of uranium atoms in a chain reaction. In the nuclear plant, the heat energy produced boils water into steam, which drives a turbine generator to produce electricity. Used nuclear fuel cannot explode and does not burn. Even when new, nuclear fuel is too weak to explode. Uranium mined from the ground is less than 1 percent fissionable and must be enriched to 4 percent in order to be used in a nuclear reactor. The uranium would have to be 20 to 90 percent enriched to be used as a weapon. Also, nuclear fuel does not burn when used in a nuclear reactor. In fact, it is not flammable.
With my Inspector Alert, I measure, at the surface of the pellet (α+β+γ) ≅ 201.0 μSv/h
Radioactive 14mm Vaseline Marbles + Jar

14mm (9/16″) yellow \ green Vaseline glass marbles in a nuke jar. The jar comes with 25 crackled and 25 non-crackled marbles. In normal light they seem to have a very high gloss and will have a slight glow in sun light but under black light (UV) they glow bright green. These will also register on a Geiger counter, though with a low reading of upto 200 CPM (50 CPM to 125CPM on average).
Radioactive Vaseline Marbles, Holders and Fragments

With my Inspector Alert, I measure, at the surface of the glass (α+β+γ) ≅ 5.67 μSv/h
URANIUM VASELINE GLASS PERFUME ANTIQUE BOTTLE

With my Inspector Alert, I measure, at the surface of the glass (α+β+γ) ≅ 2.57 μSv/h

With my Inspector Alert, I measure, at the top of the glass (α+β+γ) ≅ 11.51 μSv/h
Fiestaware Plates

The uranium-containing red glaze of these plates was used from 1936 to 1943. It was discontinued from 1944 to 1958 due to a shortage of uranium caused by demand from the U.S. Government to build reactors and bombs. It was produced again from 1959 to 1969. The uranium that was used during this last period was supposedly “de-enriched” by removal of the fissionable isotope, Uranium 235.
With my Inspector Alert, I measure (α+β+γ) ≅ 122.6 μSv/h
Fiestaware Vintage

Fiestaware vintage. The dishes include 2 vintage Fiesta red which has a minute amount of uranium and as well as the lead that was used in the old-style of glazing of the ware. Also included in this bid is a souvenir plate from the factory, which can be got only though touring the plant. Not yet received.
With my Inspector Alert, I measure (α+β+γ) ≅ 147.6 μSv/h
THORIUM LANTERN MANTLE

Since thorium is radioactive and produces a radioactive gas, radon-220, as one of its decay products, there are concerns about the safety of thorium mantles. Some nuclear safety agencies make recommendations about their use. A study in 1981 estimated that the dose from using a thorium mantle every weekend for a year would be 0.3-0.6 millirems, tiny in comparison to the normal annual dose of a few hundred millirems, although a person ingesting an entire mantle would receive a comparable dose of 200 mrem. However the radioactivity is a major concern for those people involved with the manufacture of mantles and with contamination of soil around some former factory sites. All of these issues have meant that alternatives, usually yttrium or sometimes zirconium, are used in some countries although they are either more expensive or less efficient.
With my Inspector Alert, I measure, at the surface (α+β+γ) ≅ 61.80 μSv/h

Potassium Chloride

Potassium40(K40) is a naturally-occurring radionuclide. Wherever there is potassium, there is potassium40. If there is enough potassium, the K40 can be detectable with a simple survey instrument. Half-life: 1.28 x 109 years; Decay Mode: Beta decay (89.3%). The beta maximum energy is 1.31 MeV. Gamma Rays: 1461 keV (10.7%). Daily intake of potassium element: 3.3 grams. Amount of potassium element in body: 140 grams (1.5 pCi/g or 55 Bq/kg of body weight). Typical K40 activity in body: 0.1 μCi; This means that there are over 200,000 atoms of K40 that decay in the body each minute! Typical K40 activity in soil: 10 to 20 pCi/g. Dose from Potassium40: The dose to a typical member of the population is approximately 15-20 mrem/year due to the K40 in the body and 10 mrem/year due to the gamma rays emitted by K40 in the environment (primarily the soil). The human body maintains relatively tight homeostatic control over potassium levels. This means that the consumption of foods containing large amounts of potassium will not increase the body’s potassium content. As such, eating foods like bananas does not increase your annual radiation dose.
With my Inspector Alert, I measure (α+β+γ) ≅ 1.67 μSv/h
Fire Smoke Detectors (Am-241)

The vital ingredient of these household smoke detectors is a very small quantity (<35 kBq) of americium-241 (Am-241). This element was discovered in 1945 during the Manhattan Project in USA. The first sample of americium was produced by bombarding plutonium with neutrons in a nuclear reactor at the University of Chicago. Americium is a silvery metal, which tarnishes slowly in air and is soluble in acid. Its atomic number is 95. Its most stable isotope, Am-243, has a half-life of over 7500 years, although Am-241, with a half-life of 432 years, was the first isotope to be isolated. Americium oxide, AmO2, was first offered for sale by the US Atomic Energy Commission in 1962 and the price of US$ 1500 per gram has remained virtually unchanged since. One gram of americium oxide provides enough active material for more than 5000 household smoke detectors. Betalight Tritium Torch The Betalight is a self-illuminated unit with a wide range of uses is compact, robust and has an in-service life of over ten years. Illuminates without affecting night vision. A glass capsule internally phosphor-coated and filled with H3 tritium gas, activates the phosphor to emit light. With my Inspector Alert, I measure (β+γ) ≅ 8.43 μSv/h NiTE Tritium Glowrings and vials Nite Glowrings are laser sealed borosillicate glass vials which are internally coated with phosphor injected with gas which then reacts with the phosphor to create a cold energy which produces a low level light source with no filaments or heat dissipation and no risk of fire or explosion. They are unaffected by water, oil and most corrosive materials and require no external power source or exposure to light, remaining fail-safe and maintainance free. Nite Glowrings lights are also used in many other applications such as in the dials and hands of wrist watches, LCD display panels, level bubbles and directional signage. With my Inspector Alert, I measure (β+γ) ≅ 30.01 μSv/h UZI-001-R Protector, H3 TRITIUM DIVER Watch Movement: High Quality Swiss Component Movement. Crown: Screw Down. Case Diameter: 44mm. Water Resistance: 200 Meters (660 Feet). Crystal: Hardened Mineral Crystal. ILLUMINATION: 7 TRITIUM VIALS (SUPER BRIGHT!!! 25 milicuries of TRITIUM per vial – maximum allowed by US law). At 12: Two Red Vials. At 3, 6 ,9: Green Vials. H/M Hands: Green Vials. DATE Display at 4:30 TRASER H3 P6500 NAVIGATOR Military specs TRITIUM Watch Traser watches are the easiest in the world to read in low light conditions and even in total darkness. Thanks to its research, the Swiss Company MB-Microtec Ag has succeeded in manufacturing a self-activated light source that is 100 times brighter than any previously available. The light-emitting devices require no battery power or any other form of charging, and never need servicing or maintenance. Traser watches are equipped with a tritium light source. These tiny airtight vials are sealed under high pressure, and are resistant to water, oil and the most corrosive materials. A minute quantity of tritium lights up the dye. These merits have made traser-watches an absolute must in the emergency, safety and protection sectors as well as in the armed forces, but are also ideal for fans of adventure and sport. H3 TRASER are top quality Swiss watches, extremely robust and reliable. Chosen by the worlds elite military units, including the SAS, SBS, US Navy Seal Teams, H3 watches have proven themselves on active duty throughout the world.

The “LIQUIDATORS” is a collective name for Soviet firefighters, military, search & rescue, police, emergency situation ministry, civil defense personal and many other ordinary heroes – all participants in The Clean Up OPERATION of CHERNOBYL NUCLEAR POWER STATION DISASTER. In Russian exactly it says: “The participant of liquidation of consequences of failure on an atomic power station” [Uchastnik Likvidatzii Posledstviy Avarii na AES]. Len.VO abbreviation on the top means Leningrad Military District. “CHERNOBYL” in Russian below. Soviet Red Star and Red Banner Communist Symbols and miniature of the Lenin Order Award. Well-made heavy brass, hand-enameled bright deep colors. CHERNOBIL NUCLEAR DISASTER LIQUIDATION PARTICIPANT The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel and without proper regard for safety. The resulting steam explosion and fire released about five percent of the radioactive reactor core into the atmosphere and downwind. The April 1986 disaster at the Chernobyl nuclear power plant in the Ukraine was the product of a flawed Soviet reactor design coupled with serious mistakes made by the plant operators in the context of a system where training was minimal. It was a direct consequence of Cold War isolation and the resulting lack of any safety culture. The accident destroyed the Chernobyl-4 reactor and killed 30 people, including 28 from radiation exposure. A further 209 on site were treated for acute radiation poisoning and among these, 134 cases were confirmed (all of whom recovered). Nobody off-site suffered from acute radiation effects. However, large areas of Belarus, Ukraine, Russia and beyond were contaminated in varying degrees. The Chernobyl disaster was a unique event and the only accident in the history of commercial nuclear power where radiation-related fatalities occurred. Subsequent studies in the Ukraine, Russia and Belarus were based on national registers of over 1 million people possibly affected by radiation! The power plant is located at 51°23’23″N, 30°5’58″E, near Pripyat, Ukraine, at the time part of the Soviet Union.
