Hubble Reveals Backwards Galaxy

Article written: 7 Feb , 2002

The latest image released from the Hubble Space Telescope shows a spiral galaxy that seems to be rotating in the wrong direction. Astronomers expected that galaxy NGC 4622, located 111 million light-years away in the constellation Centaurus, should rotate counter-clockwise but it actually goes clockwise. It’s believed that the galaxy consumed a smaller companion galaxy recently which helped reverse its spin.

    “Helped reverse its spin!” Hmm . . . can’t help wondering how much energy was required for the reversal.
