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).

Very interesting, but I don't think that exposure date is correct; HST
did not do much science that month (SM3B).

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

Are you sure? 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...
