![Arp 107 (NIRCam and MIRI Image)](http://stsci-opo.org/STScI-01J748X0ZXT252FZ802FWB5608.png)
Caption
This composite image of Arp 107, created with data from the James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) reveal a wealth of information about the star-formation and how these two galaxies collided hundreds of million years ago.
The near-infrared data, shown in white, shows older stars, which shine brightly in both galaxies, as well as the tenuous bridge of gas and stars that runs between them. The vibrant background galaxies are also brightly illuminated in this wavelength.
On the other hand, MIRI data shows the young stars and star-forming regions in vibrant orange and red. Our view in the mid-infrared provides the best view of the collision point, given the noticeable gap at the top of the spiral galaxy. This collision not only began a new bout of star formation in the region, but also an endearing smile.

About The Image | |
Color Info | These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam and MIRI instruments. Several filters were used to sample wide 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: NIRCam> Blue: F090W + F150W, Green: F200W+ F277W, Red: F356W + F444W MIRI> Yellow: F770W, Orange: F1000W, Red: F1500W |

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. |
