摘要

描述
English: The NASA/ESA Hubble Space Telescope has captured this image of dwarf irregular galaxy Holmberg II. The galaxy is dominated by huge bubbles of glowing gas, which are sites of ongoing star formation. As high-mass stars form in dense regions of gas and dust they expel strong stellar winds that blow away the surrounding material. The cavities are also blown clear of gas by the shock waves produced in supernovae, the violent explosions that mark the end of the lives of massive stars.

This image is a JPEG version of the original TIFF image at File: Irregular galaxy Holmberg II (captured by the Hubble Space Telescope).tif.

This JPEG version should be used when displaying the file from Commons, as the MediaWiki software is unable to create a thumbnail or preview of the original TIFF file, because it is larger than 1000 megapixels. However, any edits to the image should be based on the original TIFF version in order to prevent generation loss, and both versions should be updated. Do not make edits based on this version.
