According to new data from NASA's Spitzer space telescope, it appears that the process of turning a giant vortex of gases and dust into a star the size of the Earth takes much longer than scientists thought until now. The popular opinion was that it takes approximately 10 million years, but it is probably hundreds of millions of years.
The scientists thought that stars are formed when the dust in its disc-like shape begins to gather around a young star, after which some of the dust clumps grow into mountains and smash into each other, thus actually forming "embryonic stars". This process, according to popular opinion, takes about 10 million years - the blink of an eye in astronomical terms, after which a longer process of annihilation of the unusable material begins.
In any case, the new findings reveal that the "god phase" - the phase of the creation of the embryonic stars, is longer. Some of the dust rings around stars remain large and bright, even though the stars near them have already reached an "extreme" age of 100 or 200 million years.
The scientists claim that the rings could not survive for long, unless the violent collision between embryonic stars and huge rock masses was continuously renewed. Jonathan Gardner, one of the scientists who were first exposed to the findings, said: "Now we will have to rewrite the books."
