IC 2220, the amazing jug-shaped nebula


Toby Jug Nebula or Butterfly Nebula is an example of a reflection nebula, also known as IC 2220, is located about 1200 light-years from Earth in the Southern constellation of Carina. Toby Jug Nebula is a cloud of gas and dust brightly lit by the middlemost star, titled HD 65750.

This name was given by two astronomers, David Allen and Paul Murdin, and by an astrophotographer, David Malin.

The Butterfly Nebula is another name given to this cosmic object, due to similarity in appearance to a butterfly in flight.
Basically, “Butterfly Nebula” is a type of reflection nebula with a bipolar structure, produced as a result of loss of rocks from HD 65750 in an earlier phase of this evolving star. The name “Toby Jug Nebula” was coined for this object because of its shape similar to an old English Toby Jug which is a drinking vessel.
In Chile, a telescope has snapped remarkably new images of an ethereal nebula with a rarely seen structure and a curious resemblance to an English toby jug. This detailed view shows the characteristic arcing structure of the nebula, which, faithful its name, does indeed look a little like an English jug with a handle.

Wednesday, 9th October, the European Southern Observatory presented the new captured image to showcase shining arcs of the IC 2220, nicknamed the Toby Jug Nebula or Butterfly Nebula, as discovered by the ESO’s Very Large Telescope. The most productive ground-based astronomical observatory in the world is the European Southern Observatory. The organization is supported by Austria, Czech Republic, France, Denmark, Belgium, Italy, Germany, the Netherlands, Spain, Switzerland, Portugal and Brazil and by the United Kingdom.

Images from the video tour of this fascinating nebula were used by the scientists to show the nearly symmetrical butterfly-like structure nearly a light-year wide. ESO officials said that this structure is rare and is created by a short-lived phase of the star (HD 65750), considered the nebula’s heart. Also, ESO officials explained that the cloud of gas and dust illuminated by the central star HD 65750 is what is known as a reflection nebula.
Many scientists argue that the dust consists of simple and heat-resistant elements such as calcium oxide and titanium dioxide and other elements such as carbon and silicon dioxide. In the present case, elaborated studies shown that the silicone dioxide (silica) reflects the stars light.
When a star has drained a big amount of its hydrogen red giants are formed, resulting in the death of the star meaning the culmination of the astral development.
ESO representatives affirmed that even if that star was at a superior phase of life than our Sun, it is actually a lot younger than many other stars and planets from the universe, being approximately 50 million years old. The bigger the mass of the star, the bigger the consumption of its fuel will be. Stars with a lower mass will run down their fuel more slowly than large-sized stars. The estimated age of the Sun is approximately 4.6 billion years old. Billions of years from now, probably the Sun will become a red giant.
