Hubble’s NICMOS views molecular cloud OMC-1 in the Orion Nebula M42

Hi-res version of this image

Hubble’s Near Infrared Camera and Multi-Object Spectrometer (NICMOS),

an instrument newly installed during the second servicing mission done

by the crew of Space Shuttle Discovery mission STS-82, has provided a

dramatic new look at the beautiful Orion Nebula. At left, the previously

obtained WFPC2 mosaic of the Orion Nebula is

shown, and the location of the NICMOS image right is indicated.

The NICMOS image is centered on the heart of a giant molecular cloud,

OMC-1 (for Orion Molecular Cloud 1), which is not apparent in the visible

light but conspicuous in the infrared glimpsed by the new instrument.

The NICMOS image shows numerous newly formed stars, and other features

connected with the chaotic active process of star formation (the structures

in the gas). Gas is in rapid motion as stars of a large mass range are formed

in this cloud. Images like this reveal a lot of detail and will hopfully

provide a good understanding of the process of star formation.

From the STScI-PRC97-13.
