GLIMPSE Proper Archive: Galactic Center Stellar Motions Over a Decade

Over the last decade, the GLIMPSE Proper project re-imaged about 43 square degrees of the Galactic center to measure the proper motions of millions of sources within 5 degrees of the Galactic center. The dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Analyze stellar proper motions based on multi-epoch imaging of the Galactic center.
• Model the gravitational potential and mass distribution based on the motions of millions of sources.
• Identify unusual stellar trajectories or high-velocity stars based on proper motion measurements.
• Study the structure and dynamics of the Milky Way's central region based on a decade of observations.

Strengths

• Covers a significant area of about 43 square degrees around the Galactic center.
• Tracks millions of sources over a temporal baseline of about a decade.
• Data originates from the authoritative source, the National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in BIN and HTML formats, which may require specialized tools for analysis.
