This is because warm instruments create radiant "noise" that overwhelms the faint celestial radiation.

Two years earlier, radio antennas had detected the faint radiation left over from the Big Bang itself.

Passive equipment works by detecting the faint infrared radiation naturally emitted by almost all objects.

We walked around the room and I noticed that, like every object in Summerland, the books, too, emitted a faint yet visible radiation.

There was only herself-which she could bear-and Eathen's faint radiations.

Yes, he could see the faint radiation of the warheads.

But if she had entered the dome, a very faint radiation would still cling to her.

Well, it may be that the faint radiation from the hot mud causes ionization in the surrounding air.

The faint thermal radiation should make some black holes theoretically detectable, though observations so far draw a blank.

"Upon that same line, but now at constant velocity, there is still a very faint radiation, of a pattern I have never seen before."
