Hubble Space Telescope has clicked an image that shows the Twin Jet Nebula and its knots of expanding gas in a great detail. The nebula known as PN M2-9 was discovered in 1947 by Rudolph Minkowski.

When people will see the image, they will notice sparking lobes of material expanding in outward direction from the central star system. Two massive jets of gas are present within these lobes. The gas from these jets has been coming out at the speed of more than 620,000 miles an hour.

Scientists said that the glowing and expanding jets of gas means that an old star has been witnessing the final stage of life. In this particular case, the star has taken off its outer layers owing to which the exposed core is shining the outer layers.

Astronomers said that the Twin Jet Nebula is a bipolar nebula, meaning that it has two stars. Astronomers said that the two stars in the pair have equal mass around that of the Sun. Pattern of the motion of the two central stars around each other is like a butterfly is unfolding its wings.

Last time, Hubble's Wide FieldPlanetary Camera 2 captured the image of the Twin Jet Nebula in 1997. In the new image, observations from the telescope's Space TelescopeImaging Spectrograph have also been included.

Though the Twin Jet Nebula is a planetary nebula, there are no planets involved. Astronomers said that they have seen the Twin Jet Nebula before, but not with this level of clarity that the new image shows.
