The Boomerang Nebula is the coldest location in the known universe at roughly 2 degrees colder than empty space! This nebula is the result of the death of a red giant star, and the extreme temperature is caused by the rapid expansion of the nebula. According to thermodynamics, if you expand a gas you cool a gas (just try using one of those compressed air cans for cleaning electronics). However, according to astronomers, a single star's death could not account for a strong enough wind to create

The European Southern Observatory (ESO) released a 3 gigapixel image of Sharpless 2-54, the Eagle Nebula, and the Omega Nebula; the detail is astounding. Taken with the Very Large Telescope (VLT) located at the Paranal Observatory, Chile, the image spans roughly 2 degrees on the sky, or about 4 full moons side-by-side. One of the most iconic nebula in the sky, the Eagle Nebula is at the centre of the image.

This nebula, named Lynds' Dark Nebula (LDN) 1622 (the 1622 dark nebula catalogued by Beverly T. Lynds), is a dim and dusty cloud of gas. It is approximately 500 light years away (meaning, it takes light about 500 years to travel the distance), and about 10 light-years across (which would be about 10x bigger than our solar system). Lynds' list originally contained 1802 objects she found by visual inspection of the Palomar Observatory Sky Survey (POSS I) catalog. POSS I was a survey that imaged
