Our #HubbleTopImage features the heavyweight of the Leo Triplet 💪⁠ ⁠ Messier 66 has an unusual anatomy, with asymmetric spiral arms and an apparently displaced core. This is unusual; most often, dense waves of gas, dust, and newly born stars wind about the galaxy's centre in a symmetric way. Astronomers believe that Messier 66's once orderly shape has been distorted by the gravitational pull of its two neighbours.⁠ ⁠ The Leo Triplet of interacting spiral galaxies is part of the larger Messier 66 group. Messier 66 wins out in size over its fellow triplets — it is about 100,000 light-years across!⁠ ⁠ For more information check the link in bio.⁠ ⁠ 📷 NASA, ESA, and the Hubble Heritage (STScI/AURA)-ESA/Hubble Collaboration.
