A new infrared image of NGC 2392 shows a bubble of ionized gas, rings, and comet-like dust clumps around the hot core of a dying star. The nebula is expected to dissipate within about 10,000 years.

The image shows an unusual combination of blue light from hot young stars with red emission regions from ionized gas, suggesting a burst of star formation likely triggered by a recent gravitational interaction.
The image shows the tilted spiral galaxy NGC 1559 as seen by the James B. Space Telescope. The galaxy contains a clear central region with a distinctive open pattern in the loose spiral arms. NGC 1559 is located about 35 million light-years away in the little-seen southern constellation Reticulum. Credit: ESA/Webb, NASA & CSA, A. Leroy, J. Lee and the PHANGS team.
