Incredible Composites Blend Data from NASA's Chandra, Webb, and Hubble
NGC 346
The first image focuses on NGC 346, a star cluster in the Small Magellanic Cloud. The nearby galaxy is about 200,000 light-years from Earth and is a popular target for astronomers.
“Webb shows plumes and arcs of gas and dust that stars and planets use as source material during their formation. The purple cloud on the left seen with Chandra is the remains of a supernova explosion from a massive star,” NASA explains.
NGC 1672
NGC 1672 is a beautiful spiral galaxy that astronomers consider a “barred” spiral. A bright central region is surrounded by arms and smaller bright stars.
“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,” writes NASA.
