Explore the UniverseROMAN

ROMAN turns deep public astronomy archives into something a normal curious human can actually use. Point to a patch of sky, choose an object or enter coordinates, and scan what the public archives already know about that part of the universe. Right now it uses public MAST observations. As official Roman Space Telescope data arrive, the same doorway is ready to welcome them.

Now Public MAST Data

Scan existing public observations from missions and surveys already living in the Barbara A. Mikulski Archive for Space Telescopes.

Later Roman-Ready

Roman documentation says Roman data will be accessed through MAST and the Roman Research Nexus. This explorer is intended to include those data as they become publicly available.

WFI 300 Megapixels

Roman’s Wide Field Instrument is a visible-to-near-IR imager and slitless spectrometer with 18 H4RG detectors.

Public Mission For Anyone

No astronomy degree required. ROMAN is meant to make our universe feel reachable from an ordinary browser.

Universe Scanner

Use the sky viewer, choose a known object, or enter your own right ascension and declination. Then ask ROMAN to scan the public archive for observations near that position.

Search Controls

Explore the sky visually, select Use Viewer Center to copy its current position into the search controls, then scan the archive for observations nearby.

Ready. Resolve an object name, move around the sky, or scan the current coordinates.

What Am I Looking At?

Andromeda Galaxy (M31)

This is one galaxy — not our Solar System and not the whole Universe.

How to Use Roman Explorer

  1. Click anywhere in the sky.
  2. Or enter coordinates.
  3. Scan that region.
  4. Review what humanity has already observed there.

This sky viewer is powered by Aladin Lite. Pan and zoom, then use the live center of the view to search the archive. More Roman-specific views are planned as those data become available.

When you select an observation, its available products will appear here.

Explore real public astronomy data at your own pace. MAST and the official Roman documentation remain the sources to consult for deeper study.
