Video Demos

Static user guides can be comprehensive, but often the best way to learn a complex workflow is to watch a Portal user perform a task. The following sections provide links to narrated videos that describe both basic and advanced features of the Portal.

These videos were created some years ago, and the appearance of some Portal features has since been updated.

Search by Position

Portal searches by target name or celestial coordinates is described in the the Searching chapter, in the sub-section Basic Search.

Advanced Search

Portal searches using more detailed metadata is described in the the Searching chapter, in the sub-section Advanced Search.

Searching the Virtual Observatory

Searching the VO is also described in the section on Special Searches.

Importing and Exporting Files

The Portal interface has evolved significantly since this video was made, but it illustrates import and cross-match capabilities in more detail than in the Search a List of Targets sub-section of this Guide.

AstroView Tool

This tool is also described in the Browsing Data chapter, in the AstroView subsection.

Hubble Source Catalog Cross-match

Searching the HSC is also described in Special Searches.

Charting Tool

Read about the Chart Tool in the Data Browsing Tools section.

Spectral Viewer Tool

Read about the Spectral Viewer tool in the Data Browsing Tools section.

Download Basket

The download manager user interface is described in the Download Basket subsection.

Data Availability Notifications

You may subscribe to notifications about data availability in MAST. While this video focuses on reprocessed data from HST, notifications can be set for both HST and JWST by program ID, and may be triggered by multiple events such as: initial availability in the archive, when data become public, and when data are reprocessed for some reason.

Creating a DOI

You can use the DOI Portal to create a durable link to data obtained in the MAST Portal. In a research context, DOIs give your readers access to the exact data that were used in your analysis. This supports reproducibility in research, and is a form of acknowledgement to the observatory that produced the data.


The following tutorials illustrate how to use the Hubble Source Catalog (HSC) and the Portal for science analysis. These exercises were developed for HSC version 2, but are still useful for the current version (HSC v3.1). Some of the tutorials perform searches with the Hubble Legacy Archive interface, but the searches can be performed with the Portal just as well.
