Hubble lensing observations prepare the way for Roman science
NASA describes Hubble observations of gravitational lenses that help prepare science investigations for the Nancy Grace Roman Space Telescope.
What the record says
An October 22 image shows a foreground galaxy magnifying a more distant galaxy into an arc and a smaller reversed image. NASA explains that the distortion helps researchers estimate a lensing galaxy’s mass and investigate dark matter.
