(ESA/Hubble)  Hubble image of NGC 1073

The NASA/ESA Hubble Space Telescope has taken a picture of the barred spiral galaxy NGC 1073, which is found in the constellation of Cetus (The Sea Monster). Our own galaxy, the Milky Way, is thought to be a similar barred spiral, and the study of galaxies such as NGC 1073 can help astronomers learn more about our celestial home.

This rich wide-field view captures not only the edge-on galaxy NGC 1055 at the centre but also the bright galaxy NGC 1068 (also known as Messier 77, it is an active galaxy with a huge black hole at its centre) to its lower-left, the fainter galaxy NGC 1032 to the upper right and the barred spiral galaxy NGC 1073 to the upper left. In addition, much closer to home, the bright naked-eye blue star Delta Ceti appears at the right of centre. This picture was created from images in the Digitized Sky Survey 2.

NGC 1073

NGC 1073 is a barred spiral galaxy located towards the constellation Cetus, the Sea Monster. The classification of “barred spiral” comes from the bar-like structure in the center of the galaxy, a trait shared by our own Milky Way and many other spiral galaxies.

The bars are thought to be created by gravitational density waves gathering material to the center of the galaxy, fueling new star formation and possibly feeding supermassive black holes. Astronomers have noticed that bars tend to appear in older galaxies rather than younger galaxies, suggesting that the bar may demonstrate a transition in galactic evolution.

NGC 1073

NGC 1073 is a barred spiral galaxy located about 55 million light years away towards the constellation Cetus, the Sea Monster. The galaxy is about 80,000 light years across. In this image, three quasars are circled, as well as X-ray source IXO 5. The quasars, incredibly bright objects thought to be created from matter falling in to supermassive black holes, are actually located in galaxies billions of light years behind NGC 1073.

Many spiral galaxies, our own Milky Way included, form bar-like structures. These are believed to originate from gas funneled into the center of the galaxy by gravitational density waves. This can serve to provide material for new stars, as well as feed supermassive black holes present in almost every galaxy. It is also thought that the bar structure is a sign of a galaxy’s age, as the form is more often seen in older galaxies.
