A 'shadow' cast on the faint, leftover glow of the Big Bang has revealed a giant object in the early Universe that defies our ...

A team of astronomers has detected a brown dwarf with a scorching daytime temperature of 8,000 Kelvin (13,940 degrees Fahrenheit). This means this extremely hot object is hotter than our very own Sun, ...

Say I have an IR thermal measuring gun. I point it at things, things that are hot measure hotter. Is there ever a scenario where a hot object measures as not hot? I don't mean some strange situation ...

(via Backyard Scientist) Today I put the Leidenfrost effect to the test! Im trying out a great question from somebody on my facebook page. He wanted to know if a hot object will fall faster than a ...

The laws of thermodynamics are pretty straightforward: Normally, heat from a hot object will flow to a cold one until they reach the same temperature, bringing the system to a state of equilibrium.

(Nanowerk News) Infrared cameras are the heat-sensing eyes that help drones find their targets even in the dead of night or through heavy fog. Hiding from such detectors could become much easier, ...

A cool newfound planet-like object may have started its life as hot as a star. New research shows that the object, known as WISE J0304-2705 and classified as a Y dwarf, may have begun its evolution ...

You might think that a hot object pushes atoms and molecules away due to radiation pressure. But a research team showed that for a polarizable atom, the opposite occurs: the hot object attracts it.
