HUBBLE SENDS SEASON'S GREETINGS FROM THE COSMOS TO EARTH

     Looking like a colorful holiday card, a new image from
NASA's Hubble Space Telescope reveals a vibrant green and red
nebula far from Earth.

     The image of NGC 2080, taken by Hubble's Wide Field and
Planetary Camera 2, designed and built by NASA's Jet
Propulsion Laboratory, Pasadena, Calif., is available online
at http://www.jpl.nasa.gov/images/wfpc . Images like this
help astronomers investigate star formation in nebulas.

     NGC 2080, nicknamed "The Ghost Head Nebula," is one of a
chain of star-forming regions lying south of the 30 Doradus
nebula in the Large Magellanic Cloud. 30 Doradus is the
largest star-forming complex in the local group of galaxies.
This "enhanced color" picture is composed of three narrow-
band-filter images obtained by Hubble on March 28, 2000.

     The red and blue light come from regions of hydrogen gas
heated by nearby stars. The green light on the left comes from
glowing oxygen. The energy to illuminate the green light is
supplied by a powerful stellar wind, a stream of high-speed
particles coming from a massive star just outside the image.
The central white region is a combination of all three
emissions and indicates a core of hot, massive stars in this
star-formation region. Intense emission from these stars has
carved a bowl-shaped cavity in surrounding gas.

     In the white region, the two bright areas (the "eyes of
the ghost") - named A1 (left) and A2 (right) -- are very hot,
glowing "blobs" of hydrogen and oxygen. The bubble in A1 is
produced by the hot, intense radiation and powerful stellar
wind from one massive star. A2 contains more dust and several
hidden, massive stars. The massive stars in A1 and A2 must
have formed within the last 10,000 years, since their natal
gas shrouds are not yet disrupted by the powerful radiation of
the newborn stars.

     The Space Telescope Science Institute is operated by the
Association of Universities for Research in Astronomy, Inc.,
for NASA, under contract with the Goddard Space Flight Center,
Greenbelt, Md. The Hubble Space Telescope is a project of
international co-operation between the European Space Agency
and NASA. The California Institute of Technology in Pasadena
manages JPL for NASA.
