Do stars take birth in Galaxy? A question that makes everyone wonder. Well, it is now which was first ever discovered that the Pinwheel Galaxy is the galaxy whose spiral arms has more than 3,000 star birth regions, and has the most of any similar type of galaxies so far observed in our own Galaxy pronounced by Benjamin Pope, a NASA Sagan fellow at New York University's Center for Cosmology and Particle Physics and one of the researchers. The Pinwheel Galaxy is considered to be a face-on spiral galaxy distanced 21 million light-years away from Earth in the constellation Ursa Major.

A team of international scientists has recently discovered a new, massive start system which also challenges existing theories of how large stars eventually die. The Pinwheel belongs to a group of galaxies that are all interacting with each other gravitationally. As a result of this dance, their shapes are distorted.

In specific, into the scientists to go more in-depth detected a gamma-ray burst progenitor system -- a type of supernova that blasts out an extremely powerful and narrow jet of plasma and which is thought to occur only in distant galaxies.

The system, estimated 8,000 light years away from Earth, is adorned with a dust named "pinwheel" -- whose strangely slow motion suggests current theories on star deaths may be unfinished. The most massive stars in our universe are near end of their lives, which produce fast winds ( carries away the star's rotational energy and slow it down long before it dies.) consistently moving at more than 1,000 kilometers per second whose purpose is to carry away a large amount of star’s mass.

These massive stars are known to be found with a partner from which the fast winds of dying stars collide with its companion to produce a shock that emits at X-ray and radio frequencies and produces exotic dust patterns.

Joseph Callingham, a postdoctoral fellow at the Netherlands Institute for Radio Astronomy and lead author of the paper said that "Apep's dust pinwheel moves much slower than the wind in the system," if one of these massive stars rotate in way tearing apart and it is then, it runs out of fuel and is ready to explode as a supernova which will then collapse at the poles before the equator, producing a gamma-ray burst."

The work put into the discovery of this system “Apep," include scientists from the Netherlands Institute for Radio Astronomy, the University of Sydney, the University of Edinburgh, the University of Sheffield, and the University of New South Wales.
