A disc around a massive baby star (artist's impression)

Artist's impression of a dusty disc closely encircling a massive baby star. Astronomers have been able to obtain the first image of such a disc, providing direct evidence that massive stars do form in the same way as their smaller brethren — and closing an enduring debate.The flared disc extends to about 130 times the Earth–Sun distance — or astronomical units (AU) — and has a mass similar to that of the star, roughly twenty times the Sun. In addition, the inner parts of the disc are shown to be devoid of dust.
