- EDGE-ON PROTOPLANETARY DISK IN THE ORION NEBULA
-
- Resembling an interstellar Frisbee, this is a disk of dust seen edge-on
- around a newborn star in the Orion nebula, located 1,500 light-years
- away. Because the disk is edge-on, the star is largely hidden inside,
- in this striking Hubble Space Telescope picture. The disk may be an
- embryonic planetary system in the making. Our solar system probably
- formed out of just such a disk 4.5 billion years ago. At 17 times the
- diameter of our own solar system, this disk is the largest of several
- recently discovered in the Orion nebula.
-
- The left image is a three-color composite, taken in blue, green, and
- red emission lines from glowing gas in the nebula. The right image was
- taken through a different filter, which blocks any bright spectral
- emission lines from the nebula, and hence the disk itself is less
- distinctly silhouetted against the background. However, clearly
- visible in this image are nebulosities above and below the plane of the
- disk; these betray the presence of the otherwise invisible central
- star, which cannot be seen directly due to dust in the edge-on disk.
-
- The images were taken between January 1994 and March 1995, and a study
- of their characteristics has been submitted for publication to the
- Astronomical Journal.
