NOTE: Most of the High Level Science Products are unavailable while
unscheduled maintenance is being performed. They will be incrementally
restored over the course of this week. We apologize for any inconvenience.
The Mikulski Archive for Space Telescopes (MAST) is a NASA funded project to
support and provide to the astronomical community a
variety of astronomical data archives,
with the primary focus on scientifically related data
sets in the optical, ultraviolet, and near-infrared parts of the spectrum.
MAST is located at the Space Telescope Science Institute (STScI).
Names of objects are passed to a name resolver that associates known object names with sky coordinates. A wide variety of catalog
and common names can be resolved to known objects. Coordinates may be given in a variety of formats; right ascensions must be positive
and southern declinations require a leading negative sign. Examples of valid names and coordinate formats are given below. A search radius
may be specified by appending "r=" and the radius in arcseconds, arcminutes, or degrees (e.g. "r=.2d", "r=5m", "r=1s").
Objects from standard catalogs such as Messier and NGC will be resolved
Antennae, Eta Carinae
Common names often work
Variable star names often work
Star catalogs with coordinate symbols
Other catalogs with coordinate and decimal symbols
All-sky catalogs with coordinate symbols
All-sky satellite catalogs with restricted symbols
