The extremely low operational temperature of just a tenth of a degree above absolute zero (0.1 K) has been reached on the detectors of Planck’s High Frequency Instrument (HFI). This makes the HFI ...

Temperature is a measure of the average energy of a collection of particles. (This is in contrast to kinetic energy, which is a measure of the energy carried by a single particle.) So, to answer a ...

The findings released Thursday bolster a key theory called inflation, which says the universe burst from subatomic size to its now-observable expanse in a fraction of a second. The new observations ...

I was reading about the quest for absolute zero temperature in New Scientist (18 March, p 10). Is there an equivalent maximum temperature? If so, what is it? And how could one reach it? I was reading ...

Earth may seem like a place with a lot of diversity, and in many ways, it is. Our planet is home to organisms that are smaller than the tip of a needle, while a few are the size of a building (like ...
