This detailed view shows the central parts of the nearby active galaxy NGC 1433. The dim blue background image, showing the central dust lanes of this galaxy, comes from the Hubble Space Telescope. The other colored structures near the middle of the image are from ALMA observations. ALMA is the Atacama Large Millimeter/sub-millimeter Array, an astronomical interferometer of radio telescopes in the Atacama desert of northern Chile.

NGC 604 is region of star formation inside the Triangulum Galaxy, an estimated 2.7 million light-years away. It’s huge, roughly 1,520 light-years across which makes it over 40 times the size of the visible portion of the Orion Nebula near us in the Milky Way. It’s also incredibly bright. If it were as close to us as the Orion Nebula, it would outshine Venus.

NGC 2985 is a spiral galaxy in the constellation Ursa Major. It’s about 70 million light-years from Earth and measures roughly 95,000 light years across, slightly smaller than the Milky Way.

Messier 2 or M2 (aka NGC 7089) is a globular cluster in the constellation Aquarius. It’s one of the larger globular clusters known—rich, compact, and significantly elliptical—containing over 150,000 stars. It’s one of the oldest globulars in our galaxy, around 13 billion years old. This Hubble image shows the core of the cluster.
