I spend 2 hours a week in an infrared sauna.

I sit in an infrared sauna everyday and microwave myself. It's really detoxifying.

The future infrared space telescope will cover that area in a much more efficient manner.

If you're in a motion-capture studio, you have spherical, reflective markers, which are picked up by cameras that emit infrared - it reflects it, and then the cameras pick up the data.

In the late 1960s, red and the low green LEDs and the infrared semiconductor lasers had already been developed, but there was no prospect of practical blue light emitters, even in the '70s.

The Next Generation Space Telescope, which will be located much further away from the Earth than the Hubble Space Telescope presently is, will also explore the infrared part of the spectrum.

Archaeologists have used aerial photographs to map archaeological sites since the 1920s, while the use of infrared photography started in the 1960s, and satellite imagery was first used in the 1970s.

For example, some stars put out large amounts of energy in the infrared part of the spectrum, so that this can produce a different relative magnitude rating than using light energy from the middle of the spectrum.

The next innovation, Sensavision, will be like a Walkman attached to your forehead. You won't actually have your head wired because infrared wires will send signals to you. In 2007 Mick Jagger will be on stage, and when Mick feels heat, you'll feel heat.

Archaeologists use datasets from NASA and commercial satellites, processing the information using various off-the-shelf computer programs. These datasets allow us to see beyond the visible part of the light spectrum into the near, middle, and far infrared.

In terms of what I wanted to do before I got into politics, I was a businessman. I ran a company that makes and sells infrared night vision military technology and solar technology, so I wanted to grow that company and pursue groundbreaking technology in each of those areas.

The bottom line is that finding orphan planets - small, faint, and located who-knows-where - is not for the faint of heart. The task is comparable to observing a match flame at the distance of Pluto. The WISE satellite, a hi-tech, space-based infrared telescope especially suited for such work, has found only a few.

At 3-D Imax theaters, audiences have shown they are willing to pay a premium to wear headgear fitted with liquid-crystal lenses synchronized via infrared signals with the movie projector, which runs at twice the normal frame rate. These movie viewers plumb new depths in depth perception - they experience extreme realism.

Everything we know about the universe is studied by using telescopes or other instruments that look at visible light, infrared, ultraviolet or X-ray - different wavelengths of electromagnetic interactions. Only 4 percent of what's in the universe gives off electromagnetic radiation, so we don't have any handle on the rest.

One of the reasons NEOWISE is so valuable is that it sees the sky in the thermal infrared. That means that instead of seeing the sunlight that asteroids reflect, NEOWISE sees the heat that they emit. This is a vital capability, since some asteroids are as dark as coal and can be difficult or impossible to spot with other telescopes.
