This Chandra X-Ray Observatory image of the young star cluster NGC 346
highlights a heart-shaped cloud of 8 million-degree Celsius gas in the central
region. Evidence from radio, optical and ultraviolet telescopes suggests that
the hot cloud, which is about 100 light years across, is the remnant of a
supernova explosion that occurred thousands of years ago.
The progenitor could have been a companion of the massive young star that is
responsible for the bright X-ray source at the top center of the image. This
young star, HD 5980, one of the most massive known, has been observed to undergo
dramatic eruptions during the last decade. An alternative model for the origin
of the hot cloud is that eruptions of HD 5980 long ago produced the cloud of hot
gas, in a manner similar to the gas cloud observed around the massive star Eta
Carinae. Future observations will be needed to decide between the alternatives.
Until then, the nature of the heart in the darkness will remain mysterious.
