Chandra Science Highlight. NGC 2841: Galactic Chimneys Turn Up the Heat. Rapid outflows of gas from giant stars, and supernova explosions in the disk of a galaxy create huge shells or bubbles of hot gas that expand rapidly and rise above the disk like plumes of smoke from a chimney.

  1. Chandra Science Highlight NGC 2841: Galactic Chimneys Turn Up the Heat • Rapid outflows of gas from giant stars, and supernova explosions in the disk of a galaxy create huge shells or bubbles of hot gas that expand rapidly and rise above the disk like plumes of smoke from a chimney. • Chandra’s image of NGC 2841 provides direct evidence for this process, which pumps energy into the thin gaseous halo that surrounds the galaxy. • Galactic chimneys also spread hot, metal enriched gas away from the disk of the galaxy into the halo. This X-ray/optical composite image of the large spiral galaxy NGC 2841 shows multimillion degree gas (blue/X-ray) rising above the disk of stars and cooler gas (gray/optical).    Credit: X-ray: NASA/CXC/U.
