Cold, dusty discs of debris have been clearly detected around stars in other planets - harboring Solar Systems for the first time as revealed by NASA's Spitzer Space Telescope.  The finding raises questions about why the discs were found around some stars and not others.

The heavenly bodies of our Solar System are thought to have begun as a disc of gas and thus about 4 billion years ago.  As the planet and other large bodies gradually united, they swept up dust along their orbit, clearing a space around the Sun. The Sun also thinned out the original disc by sucking in dust or blowing it into space on the Solar Wind.

The new type of disc began to take shape as large objects occasionally smashed into each other and kicked up new clouds of dust. This debris disc is thought to be fed by collisions in the Kuiper Belt, a band of icy bodies beyond the orbit of Neptune. Such debris discs had been seen around a number of stars, but none of these stars were observed to have planets.

Now, a team led by Charles Beichman at NASA's yet propulsion laboratory in Pasadena, California, has used Spitzer to search for the faint infrared glow of dust around 26 stars already known to host planets. "Prior to these observations, we really did not know of any systems that harbored both planets and discs other than our own Solar System," Alycia Weinderger, an Astronomer of at the Carnegie Institution of Washington.

"The fact that until now, Astronomers had discovered 130, or so known extra Solar planets without seeing debris discs around any of them is like knowing you formed a house but not being able to find the construction materials," she said.

Since this theory matches with the Two Big BangTheory, we contacted Dr. Raj Baldev to elaborate how the large discs of gas and dust retain more dust as they evolved? 
 
He explained that the Supernova Mini Balls helped create the formation of the Universe in the beginning before developing into large Supernovae.  The Supernovae are dying stars, they are of different sizes: giant, large, medium, small and tiny.  The giant Supernova can carry even the mass of about 10 million times more than the Sun. (The mass of the Sun is 3,33,000 times more than the Earth).

"The explosions of giant Supernovae that threw their Supernova remnants carrying both dust and iron also formed Solar System. It   helped form different planets and stars. The surplus particles around them were sucked by the gravity of stars or planets after their formations.

"Those Supernovae, he explained, carried the property of dust, iron and neutrons; the dust normally remain floating around the planets and stars in the form of gas of discs and dust. The dust is sucked by the gravity and the property of neutron particles normally remains undisturbed. The neutrons form their independent structure, which is composed of 10-15 miles in radius.

"A neutron star explodes only under gravity and it contains total neutrons. The neutron particles are very heavy and normally they float around whether they are stars or planets. They are so heavy that a spoonful of neutrons carries billions of tons of weight. The dust is absorbed and the neutron particles remain floating where they are unable to form their own independent make-up," Dr. Raj Baldev said.

The latest finding of the astronomers and NASA match with the theory of the Two Big Bangs Theory in terms of icy era and formation of the Universe through Supernovae stars..
