connectVideoNASA can find ‘butterfly’ in the space
Beautiful photos thanks to NASA’s Spitzer Space Telescope have revealed a ‘butterfly’ – shaped nebula 1400 light years from the Sun. Officially known as W40, this red butterfly in space is a nebula, or giant cloud of gas and dust. The ‘wings’ of the butterfly are gigantic bubbles of gas is blown from the inside to the outside by massive stars.
Simultaneously with the arrival of spring and insects buzzing, flying and crawling everywhere, NASA has found a butterfly in the last place where you would think — space.
Much to the dismay of entomologists everywhere, it is not a new kind of butterfly, but a couple of huge gas clouds from 1400 light-years from the Sun. Known as Westerhout 40 (W40), the formation is in a mist, or “a giant cloud of gas and dust in space where new stars may form,” says NASA-JPL blog post.
“Besides the fact that beautiful, W40 illustrates how the formation of stars results in the destruction of the clouds, which helped create them,” the space agency added in the post. “Within giant clouds of gas and dust in space, the force of gravity pulls the material together in dense clumps. Sometimes these clumps reach a critical density that allows stars to form in their cores.”

The “wings” of W40 are made of gas, that was “ejected from a dense cluster of stars which lies between the wings in the image,” NASA continued. The color is largely responsible for the cluster of stars in the centre, and as a star matter.
In addition to W40, there is still a cluster of stars seen in the upper right part of the image, is known as Serpens South. The youngest of the two nebulae, Serpens South still has the stars embedded in the clouds, but will eventually “break out to produce bubbles such as that of the W40.”

NASA said that it is a wonderful picture came from the Spitzer Space Telescope and is a composite of four individual photos taken using the infrared camera of the space telescope.
