Galaxies, Stars and Nebulae series A gorgeous greetings card featuring a star forming region in Constellation Cygnus (The Swan). This Hubble image shows a dust-rich, interstellar gas cloud with a new-born star in the centre of the hour-glass shape. The glowing blue of the hydrogen in this nebula is due to the jets being emitted from the forming star as dust falls into into it and this causes the heating and turbulence of the hydrogen. The star, known as S106 IR, is reaching the end of its birth and will soon enter the much quieter period of adulthood known as the main stage.
