I hope you see things that startle you. I hope you feel things you never felt before. I hope you meet people with a different point of view. I hope you live a life you`re proud of, and if you find that you`re not, I hope you find the strength to start all over again.

Why Do Some Galactic Unions Lead to Doom?

Three images from our Spitzer Space Telescope show pairs of galaxies on the cusp of cosmic consolidations. Though the galaxies appear separate now, gravity is pulling them together, and soon they will combine to form new, merged galaxies. Some merged galaxies will experience billions of years of growth. For others, however, the merger will kick off processes that eventually halt star formation, dooming the galaxies.

Only a few percent of galaxies in the nearby universe are merging, but galaxy mergers were more common between 6 billion and 10 billion years ago, and these processes profoundly shaped our modern galactic landscape. Scientists study nearby galaxy mergers and use them as local laboratories for that earlier period in the universe’s history. The survey has focused on 200 nearby objects, including many galaxies in various stages of merging.

Merging galaxies in the nearby universe appear especially bright to infrared observatories like Spitzer. In these images, different colors correspond to different wavelengths of infrared light, which are not visible to the human eye. Blue corresponds to 3.6 microns, and green corresponds to 4.5 microns - both strongly emitted by stars. Red corresponds to 8.0 microns, a wavelength mostly emitted by dust.
