Hubble sees 'Comet Galaxy' being ripped apart by galaxy cluster 1-3 EPISODE

1. The NASA/ESA Hubble Space Telescope, in collaboration with several other ground- and space-based telescopes, has captured a galaxy being ripped apart by a galaxy cluster's gravitational field and harsh environment. The finding sheds light on the mysterious process by which gas-rich spiral-shaped galaxies might evolve into gas-poor irregular- or elliptical-shaped galaxies over billions of years. 2. Hubble has delivered an unrivalled snapshot of the nearby barred spiral galaxy NGC 1672. This remarkable image provides a high-definition view of the galaxy's large bar, its fields of star-forming clouds and its dark bands of interstellar dust. 3. New Hubble observations of the massive globular cluster NGC 2808 provide evidence that it has three generations of stars instead of one as current theories predict.
