Galaxy Centaurus A

Observed in 1998

This dramatic image captures a turbulent firestorm of star birth along a nearly edge-on dust disk girdling the nearby active galaxy Centaurus A. Brilliant clusters of young, blue stars blaze along the edge of the dark dust lane, marking regions where dense clouds of gas and dust are collapsing to form new stellar generations. Centaurus A is one of the closest radio galaxies to Earth and represents the aftermath of a cosmic collision between an elliptical galaxy and a smaller spiral galaxy millions of years ago. The merger left behind this distinctive warped dust lane cutting across the galaxy's center, creating ideal conditions for intense star formation. The galaxy also harbors a supermassive black hole at its core that powers powerful jets of particles extending far into intergalactic space, making Centaurus A a fascinating laboratory for studying both galactic mergers and active galactic nuclei.
