Hubble Zooms in on Shrapnel from an Exploded Star
Release type: Hubble Heritage

Not long before the dawn of recorded human history, our distant ancestors would have witnessed what appeared to be a bright new star briefly blazing in the northern sky, rivaling the glow of our moon. In fact, it was the titanic detonation of a bloated star much more massive than our sun. Now, thousands of years later, the expanding remnant of that blast can be seen as the Cygnus Loop, a donut-shaped nebula that is six times the apparent diameter of the full moon. The Hubble Space Telescope was used to zoom into a small portion of that remnant, called the Veil Nebula. Hubble resolves tangled rope-like filaments of glowing gases. Supernovae enrich space with heavier elements used in the formation of future stars and planets – and possibly life.

Learn even more about the Veil Nebula in a discussion with Hubble Heritage Team scientists during the live Hubble Hangout at 3pm EDT on Thurs., Sept. 24 at http://hbbl.us/z7f .
