Soap Bubble In Space?
Not soap, of course, but material ejected from a supernova in the Large Magellanic Cloud (LMC), a small galaxy about 160 000 light-years from Earth visbile from our Southern Hemisphere. The bubble-shaped shroud of gas is 23 light-years across and is expanding at more than 3000 miles/second!
A slam from a shockwave like the one at the edge of this may have caused the dust around here to condense into our Sun and planets.
This is three combined images, one from Hubble’s Advanced Camera for Surveys observed with a filter that isolates light from the glowing hydrogen seen in the expanding shell, one with visible-light images of the surrounding star field that were imaged with Hubble’s Wide Field Camera 3 and archival X-ray observations taken by NASA’s Chandra X-ray Observatory.
