The Colliding Spiral Galaxies of Arp 274

The colliding galaxies of Arp 274 spans about 200,000 light years across and lies about 400 million light years away toward the constellation of Virgo.

Two galaxies are squaring off in Virgo and here are the latest pictures. When two galaxies collide, the stars that compose them usually do not. This is because galaxies are mostly empty space and, however bright, stars only take up only a small fraction of that space. But during the collision, one galaxy can rip the other apart gravitationally, and dust and gas common to both galaxies does collide. If the two galaxies merge, black holes that likely resided in each galaxy center may eventually merge. Because the distances are so large, the whole thing takes place in slow motion -- over hundreds of millions of years. Besides the two large spiral galaxies, a smaller third galaxy is visible on the far left of the above image of Arp 274, also known as NGC 5679. Arp 274 spans about 200,000 light years across and lies about 400 million light years away toward the constellation of Virgo. Credit: NASA, ESA, M.

A spiral galaxy filling the view. Its disk holds many bright red spots where stars are forming, dark reddish threads of dust that obscure light, and bluish glowing areas that hold concentrations of older stars. It has a large, glowing yellow oval area at the center, from which two spiral arms wind through the galaxy’s disk. One side of the disk appears rounded (bottom of the image) while the opposite side appears somewhat squared-off (top of the image).

A Hubble Space Telescope Imaging Spectrograph (STIS) coronagraph image of quasar 3C 273. It looks the same as the WFPC2 image, but in shades of blue. A black circle (labeled “core light blocked”) blocks the glare of the quasar. Blue-colored filamentary material is visible near the black hole. The extragalactic jet is still visible.

The image is divided horizontally by an undulating line between a cloudscape forming a nebula along the bottom portion and a comparatively clear upper portion. Speckled across both portions is a starfield, showing innumerable stars of many sizes. The smallest of these are small, distant, and faint points of light. The largest of these appear larger, closer, brighter, and more fully resolved with 8-point diffraction spikes. The upper portion of the image is blueish, and has wispy translucent cloud-like streaks rising from the nebula below. The orangish cloudy formation in the bottom half varies in density and ranges from translucent to opaque. The stars vary in color, the majority of which have a blue or orange hue. The cloud-like structure of the nebula contains ridges, peaks, and valleys – an appearance very similar to a mountain range. Three long diffraction spikes from the top right edge of the image suggest the presence of a large star just out of view.
