Physicists Cool Microscopic Drum to Near Absolute Zero

Physicists Cool Microscopic Drum to Near Absolute Zero

According to a paper recently published in Nature, researchers at the National Institute of Standards and Technology (NIST) have cooled a vibrating drum to an unprecedented one-fifth of a quantum of energy, approaching the previously perceived limit of absolute zero (1). Scientists use temperature to measure the thermal motion of […]

Supermassive Black Hole Found in the Middle of Nowhere

Supermassive Black Hole Found in the Middle of Nowhere

Astronomers at UC Berkeley have discovered a supermassive black hole in an unusual location. The black hole is approximately seventeen billion times more massive than the sun and was found in a relatively empty region of the galaxy NGC 1600 (1). Black holes are essentially regions of space with such […]

 
 

A journey to the center of the sun

A journey to the center of the sun

The Sun provides the Earth with the heat and lighting necessary for life (1). Despite years of astronomical study, however, this yellow dwarf center of our solar system remains shrouded – both literally and figuratively (1). In fact, the naked human eye cannot even look at the surface of the […]

 
 

The inner core: a mystery right below our noses

The inner core: a mystery right below our noses

Journey to the Center of the Earth While many fictional tales have been written about worlds beneath our familiar soils, research regarding the core of the Earth has only begun to scratch the surface. With temperatures around 6,000 K and pressures above 330 GPa, the inner core is an inhospitable […]
