  Boomerang Nebula
A bipolar reflection nebula that lies about 5,000 light-years away in the constellation Centaurus.
The symmetric cloud appears to have been created by a high-speed wind of gas and dust blowing from an aging asymptotic giant branch (AGB) star at a speed of 164 km/s.
The ultracool Boomerang shines with light from the central star reflected by dust and is believed to be evolving rapidly, on a timescale of about 1,000 years, to the planetary nebula stage.

The Boomerang nebula, also called the bowtie nebula since the Hubble space telescope revealed more detail, located 5,000 light-years from Earth,in the constellation Centaurus, is at 1 kelvin the coldest place known outside a laboratory.
It is formed from the outflow of gas from a star at its core.
The gas is moving outwards at a speed of about 600,000 km/h and expanding rapidly as it moves out into space.

 Great Moments in Science - Coldest Place in the Universe 2
The Boomerang Nebula first revealed itself in 1979, during a survey of the Southern Sky, when it was categorized as a "peculiar" object.
Nebula comes from the early days of astronomy, and it means that the object that you're looking at is not a little point like a planet or a star, but a big fuzzy object like a cloud (or nebula).
But with the Boomerang Nebula, you've got a lot more stuff coming out, and at a much higher speed (half a million kilometers per hour), and its been doing it long enough to get it really cold.

 Boomerang Nebula Comes Back—to Plasma
The Boomerang Nebula exhibits the bipolar symmetry that has become typical of planetary nebulae: two cones or, often, bubbles of material radiate away from the central star (which is often a double star).
In most nebulae, the plasma is sufficiently dense and excited to emit light.
We are able to see the nebula because dust particles reflect light from the central star.

A boomerang is a curved, usually wooden, device which is thrown.
Note that the word "boomerang" automatically implies it is returning; a hunting, or throwing, stick is a different thing, andthe two terms should not be used interchangeably.
Originally Nibula was a general name for any extended astronomical object, including galaxies beyond the Milky Way (some examples of the older usage survive; for example, the Andromeda Galaxy is sometimes referred to as the AndromedaNebula).

NGC 3242 is such a planetary nebula, with the stellar remnant white dwarf star visible at the centre.
Planetary nebulae in general are not at all related to planets, but instead are created at the end of a sun-like star's life as its outer layers expand into space while the star's core shrinks to become a white dwarf.
While the planetary nebula phase is thought to last for around 10,000 years, astronomers estimate the age of the outer filamentary portions of this halo to be 50,000 to 90,000 years.

It could be that the star is surrounded by a disk of dust, so only the top and bottom material can escape, or a powerful magnetic field is shaping it as it escapes.
The Hubble Space Telescope has "caught" the Boomerang Nebula in these new images taken with the Advanced Camera for Surveys.
Each lobe of the Boomerang Nebula is nearly one light-year in length, making the total length of the nebula half as long as the distance from our Sun to our nearest neighbors- the Alpha Centauri stellar system, located roughly 4 light-years away.
