CLOSE-UP OF "PROPLYDS" IN ORION
A Hubble Space Telescope view of a small portion of the Orion
Nebula reveals five young stars. Four of the stars are
surrounded by gas and dust trapped as the stars formed, but were
left in orbit about the star. These are possibly protoplanetary
disks, or "proplyds," that might evolve on to agglomerate
planets. The proplyds which are closest to the hottest stars of
the parent star cluster are seen as bright objects, while the
object farthest from the hottest stars is seen as a dark object.
The field of view is only 0.14 light-years across.
The Orion Nebula star-birth region is 1,500 light-years away, in
the direction of the constellation Orion the Hunter.
The image was taken on 29 December 1993 with the HST's Wide
Field and Planetary Camera 2.
