Images obtained by Nasa's orbital Spitzer Space Telescope and from a ground-based European telescope showed a dusty disc closely encircling a newly-born but huge star.
It is the first direct evidence that very large stars - those with masses at least 10 times that of the Sun - are born in the same way as smaller brethren, from a disk-shaped cloud of dust and gas.
A competing theory was that massive stars were formed from smaller stars that merged.
'This is the first time we could image the inner regions of the disc around a massive young star,' said Stefan Kraus of the European Southern Observatory. 'Our observations show that formation works the same for all stars, regardless of mass.'
The astronomers looked at a large star known as IRAS 13481-6124, about 20 times the mass of the Sun, located about 10,000 light years in the constellation of Centaurus. -- AFP
