Name: __________________________ Date: __________________

Read the story

NASA shared Hubble images of gravitational lenses on November 12. Gravity bends light from distant galaxies, making arcs in the images.

Hubble shows individual lenses in detail. The Roman telescope can cover a wider area to find more of them.
