Скачать или смотреть The Coldest Place In Space (-272 °C) | Boomerang Nebula | Bose-Einstein Condensate

With a temperature of 1 K, the Boomerang Nebula is the coldest place in space. Also known as the Bow Tie Nebula, it is a protoplanetary nebula.

The nebula is believed to be a star system evolving towards the planetary nebula phase. It continues to develop due to the outflow of gas from the inner core where a star in its late stage life sheds mass and emits starlight illuminating the dust in the nebula. The gas is moving outwards at a speed of 164 km/s. This expansion results in such low temperatures.

Presence of dust grains prevents light to escape from all directions, forming a distinct hourglass shape. Alma's ability to see cold molecular clouds reveals the nebula's more elongated shape, in orange.

With a temperature of -272 °C, the Boomerang Nebula is just 1 °C above the absolute zero. It is the only object discovered in space that is colder than the CMB (Cosmic Microwave Background), which is 2.7 K.

However, even lower temperatures are obtained in the laboratory in order to create Bose-Einstein Condensates.
