Galaxies outside the Milky Way
Astronomers have found a spiral galaxy that may be spinning to the beat of a different cosmic drummer.

Pictures from the NASA/ESA Hubble Space Telescope helped astronomers determine that the galaxy may be spinning clockwise by showing which side of the galaxy is closer to Earth.

Beckwith (STScI), & the Hubble Heritage Team (STScI/AURA) ... the Hubble Space Telescope imaged the nearby photogenic spiral M51 in infrared light to highlight the dust that traces the dense gas that best forms stars. To further isolate the dust, much of the optical light from stars has also been digitally removed...
