This Hubble image shows Abell 209, a galaxy cluster located about 2.8 billion light-years away in the constellation of Cetus. The color image includes both optical and infrared observations from Hubble’s Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). Twelve 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 / M. Postman / P. Kelly.

The Event Horizon Telescope Collaboration released new images of M87* from observations taken in April 2018, one year after the first observations in April 2017. The new observations reveal a familiar, bright ring of emission, the same size as as first observed. The brightest part of the ring has shifted by about 30º, to a 5 o’clock position, relative to the 2017 image. Image credit: EHT Collaboration.

Two spiral galaxies, NGC 6040 and NGC 6039, are merging together at the right side of this Hubble image. NGC 6039 is seen face-on and is circular in shape. NGC 6040 seems to lie in front of the first one. In the lower-left corner, cut off by the frame, the elliptical galaxy NGC 6041 -- a central member of the galaxy cluster that Arp 122 resides in -- appears as light radiating from a point. The color image was made from separate exposures taken in the visible and infrared regions of the spectrum with Hubble’s Advanced Camera for Surveys (ACS) and the Dark Energy Camera, which is mounted on NSF’s Víctor M. Blanco 4-m telescope at Cerro Tololo Inter-American Observatory in Chile. Four 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 / J. Dalcanton / Dark Energy Survey / DOE / FNAL / DECam / CTIO / NOIRLab / NSF / AURA / L. Shatz.

This Hubble image shows various distant galaxies in the constellation of Cetus: most of the galaxies are very small, but there are a few larger galaxies and some stars where detail can be made out; in the center there is an elliptical galaxy with a brightly glowing core and a broad disk; a reddish, warped ring of light, thicker at one side, surrounds its core; a small galaxy intersects the ring as a bright dot.

Schematic representation of the tilted accretion disk model. The black hole spin axis is assumed to be straight up and down in this illustration. The jet direction points almost perpendicular to the disk plane. The misalignment between the black hole spin axis and disk rotation axis triggers the precession of the disk and jet.
