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, so this first version is built with that future in mind.

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

V1 keeps the interface simple on purpose. You can explore visually, capture the current center of the sky viewer, and then query the archive without needing to know the MAST API syntax yourself.

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

Cosmic Context

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 viewer is powered by Aladin Lite. In this first build, ROMAN shows the live center of the view and lets you capture it into the search form. That gives us a human-friendly pan-and-zoom sky doorway right now, while the deeper Roman-specific layers come online over time.

Archive Interpretation

What Humanity Has Seen Here

Click somewhere in the universe and ROMAN will look through the public astronomical archive.

Observation Results

After a scan, ROMAN summarizes what the public archive found near your chosen coordinates. Select any observation to explore its previews, science files, and archive products.

Explore This Observation

Choose an observation from the results table and ROMAN will inspect what it contains: viewable previews first, science files explained next, and original archive downloads kept available for advanced use.

No observation selected yet

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

ROMAN is deliberately public-facing and simple, but the data underneath are real. It is not trying to replace MAST or Roman documentation. It is trying to make the universe feel approachable.
