This experiment investigates how different colors, surfaces, and materials affect an object's ability to absorb and radiate
On the other hand, if the galaxies are nearby, the abundant dust would radiate
large amounts of infrared radiation, and the telescope "should be able to measure how much dust they contain," says Koekemoer.
In the past, they have assumed that a gamma-ray burst radiates
energy equally in all directions and that the amount recorded near Earth represents but a tiny fraction of the total energy.
New computer simulations suggest that the missing baryons are indeed present but remain hidden from view because they radiate
at wavelengths notoriously difficult to detect.
At temperatures above a few hundred kelvins, molecular hydrogen, which is abundant in the clouds, radiates
most of the heat away.
Because the electrons readily turn their energy into light, the disk radiates
away nearly all of its heat before the gas disappears into the black hole.
When gas from the visible star transfers onto the disk extremely slowly, it grows as hot as 1 trillion kelvins but radiates
Water vapor efficiently radiates
heat away and may play a key role in hastening star formation, Kessler says.
Gas recently struck by the wave generally radiates
at a higher temperature, while gas farther behind the wave glows cooler.
The astronomers found that at a wavelength of 1 mm, this body radiates
much more strongly than expected.
Some have conjectured tha most of the low-energy (250-electron-volt) background pervading the Milky Way radiates
from a cavity of extremely hot gas, or plasma, within a region close to the solar system.
