Does a black hole fire up cold heart of the Phoenix?

Radio astronomers have detected jets of hot gas blasted out by a black hole in the galaxy at the heart of the Phoenix Galaxy Cluster, located 5.9 billion light-years away in the constellation Phoenix. This is an important ...

The age of the Earth's inner core revised

By creating conditions akin to the center of the Earth inside a laboratory chamber, researchers have improved the estimate of the age of our planet's solid inner core, putting it at 1 billion to 1.3 billion years old.

John Tyndall: the forgotten co-discoverer of climate science

It is surprising that the Irish scientist John Tyndall, born 200 years ago on August 2 1820, is not better known. This is despite the existence of the Tyndall Centre for Climate Change Research, the Tyndall National Institute ...

What makes Saturn's atmosphere so hot

The upper layers in the atmospheres of gas giants—Saturn, Jupiter, Uranus and Neptune—are hot, just like Earth's. But unlike Earth, the Sun is too far from these outer planets to account for the high temperatures. Their ...

A possible new way to cool computer chips

A team of researchers at Stanford University has developed a theoretical way to cool down heated objects. In their paper published in the journal Physical Review Letters, the group describes their study of heat radiation ...

Coating helps electronics stay cool by sweating

Mammals sweat to regulate body temperature, and researchers from Shanghai Jiao Tong University in China are exploring whether our phones could do the same. In a study published January 22 in the journal Joule, the authors ...
