NASA shares pic of 'dancing galaxies' 100 million light-yrs away from Earth

American space agency NASA has shared a picture captured by the Hubble telescope which shows "the delicate dance between two interacting galaxies". NASA said the galaxies are located over 100 million light-years away from Earth, adding, "Astronomers think that collisions between spiral galaxies like this can lead to the formation of another type of galaxy, known as elliptical galaxies."
