Since the galaxies that make up NGC 7469 are both almost face-on when viewed from Earth, it's easier to identify the areas where a black hole may exist. A powerful accreting supermassive black hole, surrounded by a ring of young stars, lives at the heart of the galaxy in the upper right. High-resolution infrared imagery from the James Webb Space Telescope is required to determine if the stars form differently around a central supermassive black hole compared to star formation farther out in the galaxy's arms. Webb will also help researchers trace the gas outflows, which will help pinpoint where and how the interstellar medium is affected, which subsequently drives or quenches star formation.

| About The Data | |
| Data Description | The HST observations include those from the Program (A. Evans). |
| Instrument | ACS/WFC |
| Exposure Dates | June 11, 2002, Exposure Time: 33 minutes |
| Filters | F435W, F814W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the ACS instrument on the Hubble Space Telescope. Several filters were used to sample narrow wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Blue: F435W Red: F814W |
| 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. |
