A rare and spectacular head-on collision
Légende
A rare and spectacular head-on collision between two galaxies appears in this Hubble telescope picture of the Cartwheel Galaxy / located 500 million light-years from Earth in the constellation Sculptor. The striking ring-like feature is a direct result of a smaller intruder galaxy — possibly one of two objects to the right of the ring — that careened through the core [close-up image at lower left] of the host galaxy. Like a rock tossed into a lake / the collision sent a ripple of energy into space / plowing gas and dust in front of it.
