What is Roman Space Telescope?

Short answer: The Roman Space Telescope launched in August 2026. It will take further observations of strong gravitational lenses. Hubble Space Telescope captured a cosmic sampler of targets for Roman

What is Gravitational Lensing?

Gravitational lensing occurs when the gravity of a massive foreground object bends and magnifies the light from a background object.

Hubble's Role

Hubble Space Telescope has captured a cosmic sampler of targets for the Roman Space Telescope. Astronomers will use Hubble observations to construct lens models and determine the mass of foreground galaxies.

Detecting Dark Matter

The Hubble images will help detect small imperfections in gravitationally lensed galaxy arcs that indicate the presence of small clumps of dark matter. The cold dark matter theory predicts the existence of many small dark matter clumps.

What do we know, and what is still open?

What is confirmed: The Roman Space Telescope launched in August 2026 and will take further observations of strong gravitational lenses.

What is still open: The presence of small clumps of dark matter is still a topic of research and observation.
