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). Four filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.

NGC 4631 is seen edge-on, with its disk of stars shown in pink; the filaments, shown in green and blue, extend beyond the disk into the galaxy’s extended halo; green indicates filaments with their magnetic field pointing roughly toward us and blue with the field pointing away; this phenomenon, with the field alternating in direction, has never before been seen in the halo of a galaxy. This VLA image shows a companion galaxy -- a small elliptical galaxy called NGC 4627 -- just above NGC 4631.

A series of false-color images capturing the repeated flaking of red clouds from the Great Red Spot in the Spring of 2019. In the earliest image, the flaking is predominant on the east side of the giant red vortex. The flake then breaks off from the Great Red Spot, but a new flake starts to detach in the fifth image.

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.
