This is a ground-based telescopic photo of the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. The galaxy is one of several select targets of a new initiative with NASA's Hubble Space Telescope called ULLYSES (UV Legacy Library of Young Stars as Essential Standards). The program is looking at over 300 stars to build an ultraviolet-light catalog for capturing the diversity of stars, from young to old. The program's goal is to give astronomers a much better understanding of the birth of stars and how this relates to everything from planets to the formation and evolution of galaxies. The LMC contains hot, massive, blue stars similar to the primitive composition of early galaxies, so astronomers can gain insights into how their outflows may have influenced early galaxy evolution billions of years ago. The target stars are from Hubble archival observations (yellow circles) and new observations (blue circles) under the ULLYSES program.

| About The Object | |
|---|---|
| Object Name | A name or catalog number that astronomers use to identify an astronomical object. |
| Object Description | The type of astronomical object. |
| R.A. Position | Right ascension – analogous to longitude – is one component of an object's position. |
| Dec. Position | Declination – analogous to latitude – is one component of an object's position. |
| Constellation | One of 88 recognized regions of the celestial sphere in which the object appears. |
| Distance | The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs. |
| Dimensions | The physical size of the object or the apparent angle it subtends on the sky. |
| About The Data | |
| Data Description |
|
| Instrument | The science instrument used to produce the data. |
| Exposure Dates | The date(s) that the telescope made its observations and the total exposure time. |
| Filters | The camera filters that were used in the science observations. |
| About The Image | |
