A Hubble bubble! This enormous bubble seen by our Hubble Space Telescope is being blown into space by a super-hot, massive star. Spanning 7 light-years across, this Bubble Nebula was chosen to mark the 26th anniversary of the launch of Hubble into Earth orbit.

A mere 15 million light-years away, the Southern Pinwheel galaxy is ablaze with star formation. A mosaic of Hubble Space Telescope images reveals dark spiral dust lanes lined with clusters of young stars lighting up pink clouds of hydrogen gas. Hundreds of thousands of bright blue stars shine where the gas has been cleared out by stellar winds. Older stars appear yellow or orange, because the young blue stars have already burned out.
