HUBBLE PEERS INSIDE A CELESTIAL GEODE (STScI-PRC04-26)
EMBARGOED UNTIL: 9:00 am (EDT) August 12, 2004
PHOTO NO.: STScI-PRC04-26 HUBBLE PEERS INSIDE A CELESTIAL GEODE In this unusual image, NASA’s Hubble Space Telescope captures a rare view of the celestial equivalent of a geode -- a gas cavity carved by the stellar wind and intense ultraviolet radiation from a hot young star. Real geodes are baseball-sized, hollow rocks that start out as bubbles in volcanic or sedimentary rock. Only when these inconspicuous round rocks are split in half by a geologist, do we get a chance to appreciate the inside of the rock cavity that is lined with crystals. In the case of Hubble's 35 light-year diameter "celestial geode" the transparency of its bubble-like cavity of interstellar gas and dust reveals the treasures of its interior. This image of the N44F interstellar bubble was taken with Hubble's Wide Field Planetary Camera 2 in March 2002, using filters that isolate light emitted by sulfur (shown in blue, a 1,200-second exposure) and hydrogen gas (shown in red, a 1,000-second exposure).

The archive lists the images as taken on 25 March 2002, two weeks after SM3B and apparently during the mild recommissioning for WFPC2. Bill Keel |

I can't find any reference to the LMC during that month apart from a STIS (sigh) observation. Looking up the proposal ID (6698) states 25 March 2000, which is confirmed by daily report #2588. |

I seem to have had a senior moment - so fixated on the day of month that I flat missed the year. 2000 it was... Bill Keel |
