This four-panel graphic zooms into the Hubble Space Telescope view of the galactic core. The first panel shows a wide view of the Milky Way in visible light. The second panel, which zooms into the boxed area in the first panel, shows interstellar dust obscuring much of the view of the core. The third panel zooms in yet again, but the view shifts to infrared light that penetrates the dust and exposes the core. Finally, the fourth panel is a close-up of the galactic core as seen in infrared by the Hubble Space Telescope. The locator mark in the middle designates the galaxy's nucleus, which is home to a central, supermassive black hole.

| 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. |
