Spiral Galaxy NGC 1672 | NASA Chandra & Webb (X-ray & Infrared View)

NGC 1672 is a spiral galaxy, but one that astronomers categorize as a “barred” spiral. In regions close to their centers, the arms of barred spiral galaxies are mostly in a straight band of stars across the center that encloses the core, as opposed to other spirals that have arms that twist all the way to their core. The Chandra data reveals compact objects like neutron stars or black holes pulling material from companion stars as well as the remnants of exploded stars. Additional data from Hubble (optical light) helps fill out the spiral arms with dust and gas, while Webb data shows dust and gas in the galaxy’s spiral arms.

Image Description: Shown face on, this spiral galaxy has two major arms curving away from the bright swirling light at its core. One arm extends to our lower left with a gentle upward curve. The other extends to our upper right with a curve reminiscent of a question mark. Both arms have a cloudy, silver blue quality, and are dotted with bright white and purple stars of varying sizes. In this galaxy, categorized as a "barred" spiral, the arms do not appear to reach the bright core. The space around the bright pinkish core is a swirl of murky, pale silver cloud.
