Solar Systems in the Making? The nebular hypothesis for the origin of our Solar System has been bolstered by a variety of recent observations that look very much like star and planetary systems in various stages of formation. New Solar Systems Recent Hubble Space Telescope observations shed considerable light on the birth of stars and associated planetary systems. The following image shows regions in the Orion Nebula where solar systems may be forming. Regions in the Orion Nebula where solar systems appear to be forming The Orion Nebula is approximately 1500 light years from Earth. It is visible to the naked eye as the middle "star" in the sword of the constellation Orion. These

images were taken with the Wide Field Planetary Camera 2 of the Hubble Space Telescope (C.R. O'Dell, Rice University). Details of the images show several protoplanetary disks ( proplyds ), including a single dark disk surrounding a central star (Ref) . The lower left inset figure

Here is a HST movie (650 kB MPEG) illustrating these protoplanetary disks in the Orion Nebula (original movie source ), here is a further discussion of these planetary systems now forming in Orion. More Star-Forming Regions Many other star-forming regions are known. In addition to the Eagle Nebula discussed below, here are images and discussion of Star-forming regions in the Trapezium (the central region of the Orion Nebula). Star formation in the Lagoon Nebula , with possible evidence for tornadoes 1/2 light year in length---see adjacent image ( Source ). Star-forming region in the nebula NGC 604 (in the galaxy M33 ). In each of these examples there is strong evidence that stars are being born in the region shown in the image; presumably, at least in some of the cases, attendant solar systems are being formed also....
