You see the Twin Jet Nebula in brilliant colours as seen by NASA Hubble. This is not just any planetary nebula; it is a bipolar nebula.
Unlike ordinary nebulae with a single star at its centre, this nebula has two stars at its centre, making it a bipolar nebula. One of the stars is a small white dwarf, while the other is nearing the end of its life. The two stars orbit each other roughly once every 100 years. The dying star is thought to have ejected its outer layers of gas into space and instead of a sphere, it is pulled into two lobes.
Their rotation around each other causes the wings of this cosmic butterfly to take shape. Inside the wings are two faint blue blotches, fierce twin jets that stream out into space at speeds as high as one million kilometres (621,400 miles) per hour.
Image description:
Two image scrolls show two lobes of iridescent material extending outward from a central star system. The two central stars appear as a single star in a bright white glow, forming an "x" shaped disc around them. Inside these lobes flow two large jets of gas from the star system. A green colour covers the heads of the jets and then there is a peach colour in the centre where you can see the lobes, with a slight blue colour towards the tail of the jets. The darkness of space covers the rest of the image and a few stars spread out across the image.
