The distribution of ionized hydrogen (known by astronomers as H II from old spectroscopic terminology) in the parts of the Galactic interstellar medium visible from the Earth's northern hemisphere as observed with the Wisconsin Hα Mapper (Haffner et al.
The Physics and Chemistry of the Interstellar Medium
An annotated illustration of the interstellar medium. The solar gravity lens marks the point where a conceptual spacecraft in interstellar space could use our sun as a gigantic lens, allowing zoomed-in close-ups of planets orbiting other stars.
Puppis A Supernova Remnant : Driven by the explosion of a massive star, supernova remnant Puppis A is blasting into the surrounding interstellar medium about light-years away. At that distance, this colorful telescopic field based on broadband.
