Physics Education Improves When Students Make Their Own Computer Models Jul 3, 2009
In this model they were asked to incorporate variables such as temperature and outgoing thermal radiation. These variables have the following causality: the higher the temperature, the higher the outgoing radiation. (Science Daily)
Life May Extend Planet's 'Life': Billion-year Life Extension For Earth Also Doubles Odds Of Finding Life On Other Planets Jun 16, 2009
Although the planet's greenhouse gases chiefly water vapor, carbon dioxide, and methane have become the villain in global warming scenarios, they're crucial for a habitable world, because they act as an insulating blanket in the atmosphere that absorbs and radiates thermal radiation, keeping the surface comfortably warm. As the sun has matured over the past 4. (Science Daily)
NRL part of multi-national team that launches Herschel Space Observatory May 15, 2009
For objects that are much colder than room temperature, such as the outer planets or interstellar ice and dust, the peak of this thermal radiation shifts from the mid-infrared peak at room temperature, into the far-infrared / terahertz range. Herschel's telescope and instruments are designed to detect and characterize the "cool" Universe. (EurekAlert! -- Business News)
The tiniest incandescent lamp May 5, 2009
His law assumes that thermal radiation released from a black body a perfect absorber and radiator of energy will be as disordered, or as random, as possible. For instance, a hot incandescent lamp gives off many photons of different colours which together make up make white light. (Harper's Magazine)
Astronomers discover 'new planet' Feb 17, 2008
Follow-up studies by the Tanagra Observatory have measured the thermal radiation coming from Sedna to determine how hot it is, and therefore provide some estimate of its size. Researchers believe that Sedna's surface temperature is about -240 degrees Celsius (-400 degrees Fahrenheit). (BBC News)
Supercomputers Offer New Explanation Of Tunguska Disaster Dec 20, 2007
This causes stronger blast waves and thermal radiation pulses at the surface than would be predicted by an explosion limited to the height at which the blast was initiated. Our understanding was oversimplified, says Boslough, We no longer have to make the same simplifying assumptions, because present-day supercomputers allow us to do things with high resolution in 3-D. Everything gets clearer as you look at things with more refined tools. (Science Daily)
Heritage Foundation: A License to Fight Crime More... Oct 20, 2007
In contrast, the Supreme Court struck down the use of thermal imaging devices in Kyllo, in part, because the devices could read thermal radiation that the human senses couldn t detect from public streets. Today, license-plate recognition software is used in airport parking lots, as access control monitors to restricted areas, in tollbooths on toll roads, at border-control areas, for traffic enforcement at intersections, and to assist city administrators in controlling municipal traffic loads.

Taming Tiny, Unruly Waves For Nano Optics Oct 11, 2007
The Georgia Tech research team set out to study evanescent waves in nanoscale radiation energy transfer (between two very close surfaces at different temperatures by means of thermal radiation) ... Understanding the behavior of such waves is critical to the design of many devices that use nanotechnology, including near-field thermophotovoltaic systems, nanoscale imaging based on thermal radiation scanning tunneling microscopy and scanning photon-tunneling microscopy, said Zhang.

Astronomers May Have Solved Information Loss Paradox To Find Black Holes Do Not Form Jun 22, 2007
The question that the physicists set out to solve is: what happens once something collapses into a black hole" If all information about the collapsing matter is lost, it defies the laws of quantum physics. Yet, in current thinking, once the matter goes over the event horizon and forms a black hole, all information about it is lost. "If you define the black hole as some place where you can lose objects, then there is no such thing because the black hole evaporates before anything is seen to fall... (Science Daily)
Case researchers may have solved Jun 21, 2007
The mass shrinks in size, but it never gets to collapse inside an event horizon due to evidence of pre-Hawking radiation, a non-thermal radiation that allows information of the nature of what is collapsing to be recovered far from the collapsing mass. "Non-thermal radiation can carry information in it unlike thermal radiation. This means that an outside observer watching some object collapse receives non-thermal radiation back and may be able to reconstruct all the information in the initial... (EurekAlert!)
The Threats of Nuclear Aspirations Jun 6, 2007
On the other hand, it must be told that nuclear weapons, as Yearley points out, are highly destructive in four main ways- blast; heat or thermal radiation; nuclear radiation and electro-magnetic pulse, which could ignite Climate Change and spark environmental consequences. Radioactive materials are potentially very harmful. (Ghana Web, Ghana)
Venus Express' Infrared Camera Goes Filming May 12, 2007
This is more convenient since at shorter wavelengths, the difference between the thermal radiation emitted on the day and night sides is too high to observe both regions simultaneously without blinding some channels of the camera. It is comparable to looking at bright, sun-illuminated snow and at a dark sky without having to change your glasses, said Giuseppe Piccioni, VIRTIS co-Principal Investigator. (Science Daily)
Radiant barrier can save on cooling bills May 1, 2007
All materials give off some energy through thermal radiation. The amount of energy they give off depends upon the temperature of the material and one of the properties you listed above, "emissivity." Simply, emissivity is the amount of radiation a material will emit. (Atlanta Journal-Constitution -- Home & Garden)
From one campus to another Apr 24, 2007
Sanchez and Sorenson, members of the Virginia Tech class of 2002, met at the university while participating in a thermal radiation project. They married in Blacksburg, Va. (Fresno Bee -- Local)
County's 'Shelter in place' policy neglects critical human factors considered elsewhere Apr 22, 2007
Thus, if you cannot see the flames, the thermal radiation cannot see or burn you. The wall of your house blocks the line of sight. (North County Times)
Search For Extrasolar Planets And Extraterrestrial Life Improved With Darwin's Frictionless Optics Apr 14, 2007
Darwin's ODLs are uniquely engineered to operate at cryogenic temperatures to avoid self-interference from the satellites' own thermal radiation. This is mandatory as Darwin will conduct observations at mid-infrared wavelengths, where the planet-to-starlight brightness ratio is relaxed compared to that in visible wavelengths, and where life-related marker chemicals such as water, ozone and carbon dioxide can be detected.

Life And Death Of A Photon 'Filmed' For The First Time Apr 3, 2007
A photon from the residual thermal radiation bounces back and forth over a billion times between the mirrors, which are placed 2 ... The photon comes from the residual thermal radiation which surrounds the cavity ... By observing such jumps over a period of several hours, the researchers directly confirmed the statistical properties of thermal radiation laid down a century ago by Planck and Einstein.

New Security Scanner Sees Through Clothes, But With Modesty Mar 28, 2007
Instead of bouncing x-rays off an object to create an image, the sensor Helist described simply absorbs natural thermal radiation. The device is sensitive to terahertz frequencies electromagnetic radiation from between the infrared spectrum and radio spectrum. (National Geographic)
Will Discovery Help Repel Asteroids Headed for Earth? Mar 3, 2007
The result is unbalanced thermal radiation that produces a small acceleration ... An ounce of force, caused by slight variations in thermal radiation, caused the Asteroid Golevka to shift its orbital path by almost 10 miles in 12 years. (Yahoo News -- Meteors and Asteroids)
