Through a series of theoretical calculations and supercomputer simulations, astrophysicists have determined that new stars form by gravitational collapse rather than the widely held belief that they come from the buildup of unbound gas.
NASA's Hubble Space Telescope image shows a panoramic portrait of a vast, sculpted landscape of gas and dust where thousands of stars are being born. This fertile star-forming region, called the 30 Doradus Nebula, has a sparkling stellar centerpiece: the most spectacular cluster of massive stars in our cosmic neighborhood of about 25 galaxies.
