NGC 3175 can be seen slicing across the frame in this Hubble image, with its mix of bright patches of glowing gas, dark lanes of dust, bright core, and whirling, pinwheeling arms coming together to paint a beautiful celestial scene. This image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / D. Rosario et al.

This composite image shows the surroundings of a supermassive black hole that is triggering star formation across the longest distance ever seen; as hot gas swirls around the black hole, it emits large amounts of X-rays that Chandra detects; the black hole is also the source of radio-wave emission from a jet of high-energy particles -- previously detected by scientists with the VLA -- that stretches about a million light-years.

This Hubble image shows the face-on spiral galaxy NGC 5468. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3).

NGC 6240 harbors three supermassive black holes at its core: the northern black hole (N) is active and was known before; the zoomed-in new high-spatial resolution image shows that the southern component consists of two supermassive black holes (S1 and S2); the green color indicates the distribution of gas ionized by radiation surrounding the black holes; the red lines show the contours of the starlight from the galaxy and the length of the white bar corresponds to 1,000 light years.

This composite image shows the Orion A molecular cloud, the nearest known massive star factory, as seen by ESA’s Herschel and Planck space observatories. Located approximately 1,630 light-years away, Orion A is one of the two giant molecular clouds in the Orion molecular cloud complex. The other cloud is Orion B, which lies east of Orion’s Belt. Orion A is packed full of gas -- it contains so much material, in fact, that it would be capable of producing tens of thousands of Sun-mass stars. Different colors visible here indicate the light emitted by interstellar dust grains mixed within the gas, as observed by Herschel at far-infrared and sub-millimeter wavelengths, while the texture of faint gray bands stretching across the frame, based on Planck’s measurements of the direction of the polarized light emitted by the dust, show the orientation of the magnetic field.
