<p>Astronomers have captured the first direct images of a forming planet still embedded in a thick disc of gas and dust surrounding a young star, just 335 light-years from earth.<br /><br /></p>.<p>Using European Southern Observatory’s Very Large Telescope in Chile, an international team of scientists studied the disc of gas and dust that surrounds the young star HD 100546, a relatively nearby neighbour located 335 light-years from earth.<br /><br />Scientists were surprised to find what seems to be a planet in the process of being formed, still embedded in the disc of material around the young star.
