Description This collection of images show gas swirling around the same galaxy in several different ways. Taken together, these snapshots create a time-lapse projection. The top row shows the density of gas in the galaxy at a given time: in these panels, the brightest areas show where gas is most densely concentrated. In the middle row, gas shoots out of the galaxy in the bright areas and plummets toward the center of galaxy in the darkest areas. The bottom row shows temperature: the brighter the area, the hotter the gas. Models like these help astrophysicists understand the chaotic, explosive, ever-changing lives of evolving galaxies.
These images stem from cutting-edge research on campus, winning our annual Scientific Images Contest which goes on display in galleries across Chicago.
Through partnerships with schools and community groups, we train Northwestern researchers to share their expertise and creativity in a community centered way. Sales from these images goes to support our education and outreach activities, connecting researchers to the wider community.
