A Confused Galactic V

NASA/ESA Hubble

Check out a galactic-sized “flying V in this image of interacting galaxies IC 2184 from NASA’s Hubble Space Telescope.

Explore the two nearly edge-on galaxies as they begin their billion-year-long dance. What shapes or stories do you see in the image? Leave a note in the comments below.

IC 2184 is really two galaxies. Even though space is huge, galaxies graze each other all the time. Gravity is strong with both galaxies. As the galaxies interact, stars, gas and dust are flung out into space forming long tidal tails. Look close for two faint tails. Usually these tails arc far into space but they look straight in this image because we are looking at them from the edge. The tails are arcing toward or away from us.

Also look for bright, fireworks regions. Gravity not only flings stars outward but also it can smash gas and dust. The bright blue and pink bursts are hot regions where new stars are forming, similar to regions in our galaxy such as the Orion Nebula or the Carina Nebula. These areas glow brightly enough that they show up as bright blobs of light in large telescopes.

IC 2184 is found about 160 million light-years from Earth toward the faint constellation Camelopardalis, the Giraffe.
