THE NANCY GRACE ROMAN SPACE TELESCOPE: THE NEXT GREAT OBSERVATORY

Take a mirror the size of Hubble's. Give it a view one hundred times wider. Name it after the
woman who made Hubble possible. That's the Roman Space Telescope.

THE MOTHER OF HUBBLE

Nancy Grace Roman was NASA's first chief astronomer, and in the 1960s and 70s she fought the long institutional battle that turned the idea of a large space telescope into a funded program.

Colleagues called her the Mother of Hubble. Now a telescope carries her name.

A WIDER EYE

Roman's 2.4-meter mirror matches Hubble's — but its field of view is roughly 100 times larger.

Where Hubble takes portraits, Roman takes panoramas: each image covering a swath of sky that would take Hubble hundreds of exposures to stitch together.

THE MISSIONS

Roman is built to attack two of the biggest open questions in astronomy: the nature of dark energy, and the census of planets around other stars — including a microlensing survey expected to find thousands of new worlds.

It also carries a coronagraph to test technology for directly imaging exoplanets.

WHAT COMES NEXT

Roman is the next flagship in the line that runs from Hubble through Webb.

The universe is about to get a much wider window.

HUBBLE SHOWED US HOW DEEP THE UNIVERSE GOES. ROMAN WILL SHOW US HOW WIDE.
