A star formation laboratory

Galaxy NGC 4214, pictured here in an image from the NASA/ESA Hubble Space Telescope’s newest camera, is an ideal location to study star formation and evolution. Dominating much of the galaxy is a huge glowing cloud of hydrogen gas in which new stars are being born. A heart-shaped hollow — possibly galaxy NGC 4214’s most eye-catching feature — can be seen at the centre of this. Inside this cavity lies a large cluster of massive, young stars ranging in temperature from 10 000 to 50 000 degrees Celsius. Their strong stellar winds are responsible for the creation of this bubble. These features have the effect of stemming any further star formation due to the subsequent lack of gas.
