Hubble Spies One-Sided Spiral - NASA Science
The Hubble Space Telescope imaged the spiral galaxy NGC 4654, which displays an asymmetric shape caused by ram pressure stripping and gravitational forces.
Why it matters
Understanding how gas moves and collapses to form stars helps astronomers determine how galaxies evolve over time.
The details
- NGC 4654 is located 72 million light-years away in the Virgo Cluster.
- A fly-by interaction with galaxy NGC 4639 occurred approximately 500 million years ago.
- The galaxy forms nearly two Suns' worth of new stars every year.
