The Medialuna Nebula, cataloged as NGC 6888, also called Crescent Nebula or Caldwell 27, is an emission nebula in the constellation of the Swan, located 6º southwest of the star Sadr γ Cygni. The image is of the astrophotographer Sara Wager and collected in its web SwagAstro. It is at a distance of the Earth of about 4700 light-years, within our galaxy, the Milky Way.

ESO lately released a photo of the newly-discovered galaxy SMM J2135-0102, which was found when astronomers were observing a massive galaxy cluster with the Atacama Pathfinder Experiment telescope. The galaxy is so distant that we see it as it was 10 billion years ago, and it is the brightest very distant galaxy ever seen at submillimetre wavelengths. Astronomers estimate that SMM J2135-0102 is producing stars at a rate that is equivalent to about 250 suns per year.

The Cosmic Spare Tire (IC 5148) is a beautiful planetary nebula located some 3000 light-years away in the constellation of Grus (The Crane). The nebula has a diameter of a couple of light-years, and it is still growing at over 50 kilometres per second — one of the fastest expanding planetary nebulae known.
