NASA : Hubble Eyes Golden Rings of Star Formation
Hubble Eyes Golden Rings of Star Formation
Taking center stage in this new NASA/ESA Hubble Space Telescope image is a
galaxy known as NGC 3081, set against an assortment of glittering galaxies in
the distance. Located in the constellation of Hydra (The Sea Serpent), NGC 3081
is located over 86 million light-years from us. It is known as a type II Seyfert
galaxy, characterized by its dazzling nucleus.
NGC 3081 is seen here nearly face-on. Compared to other spiral galaxies, it
looks a little different. The galaxy's barred spiral center is surrounded by a
bright loop known as a resonance ring. This ring is full of bright clusters and
bursts of new star formation, and frames the supermassive black hole thought to
be lurking within NGC 3081 — which glows brightly as it hungrily gobbles up
These rings form in particular locations known as resonances, where
gravitational effects throughout a galaxy cause gas to pile up and accumulate in
certain positions. These can be caused by the presence of a "bar" within the
galaxy, as with NGC 3081, or by interactions with other nearby objects. It is
not unusual for rings like this to be seen in barred galaxies, as the bars are
very effective at gathering gas into these resonance regions, causing pile-ups
which lead to active and very well-organized star formation.
Hubble snapped this magnificent face-on image of the galaxy using the Wide
Field Planetary Camera 2. This image is made up of a combination of ultraviolet,
optical, and infrared observations, allowing distinctive features of the galaxy
to be observed across a wide range of wavelengths.
