Washington, Oct 31: The Hubble space telescope has detected a pair of gravitationally interacting galaxies that appear to mark the number ten.
The galaxies, called Arp 147, were observed by Hubble’s Wide Field Planetary Camera 2 (WFPC2).
The left-most galaxy, or the “one” in the image, is relatively undisturbed apart from a smooth ring of starlight. It appears nearly on edge to our line of sight. The right-most galaxy, resembling a zero, exhibits a clumpy, blue ring of intense star formation.
The blue ring was most probably formed after the galaxy on the left passed through the galaxy on the right.
