This graphic shows the wider context of the Bubble Nebula. The National Optical Astronomy Observatory (NOAO) image (left) by Travis Rector has been rotated and cropped to be north-up and closer to the orientation of the Hubble Space Telescope image (right). In addition to the inner bubble seen in the Hubble image, the wider view shows a large cloud complex, including two larger shells surrounding the massive star near the center.

|---|---|
| Object Name | Bubble Nebula, NGC 7635 |
| Object Description | Emission nebula, O 6.5 Star |
| R.A. Position | 23h 20m 48.3s |
| Dec. Position | 61° 12' 6.12" |
| Distance | 7,100 light-years (2,100 parsecs) |
| About The Data | |
| Data Description | The Hubble data were provided by the HST proposal taken by the Hubble Heritage Team: Z. Levay, R. Avila, C. Christian, L. Frattare, J. Green, J. Mack, C. Martlin, S. Meyett, M. Mutchler, and S. Porter (STScI/AURA), and K. Noll (NASA/GSFC). |
| Instrument | NOAO (left) and HST>WFC3/UVIS (right) |
| Exposure Dates | February 25/26, 2016, Exposure Time: 3.5 hours (HST) |
| Filters | HST: F502N ([O III]), F656N (H-alpha), and F658N ([N II]) |
| About The Image | |
| Color Info | The Hubble image (right) is a composite of separate exposures acquired by the WFC3/UVIS instrument. Several filters were used to sample various wavelengths. 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: F502N ([O III]) Green: F656N (H-alpha) Red: F658N ([N II]) |

| 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. |
