| About The Object | |
|---|---|
| Object Name | Question Mark Galaxy in MACS J0417.5-1154 |
| Object Description | Gravitationally lensed galaxy in galaxy cluster |
| R.A. Position | 04:17:34.6 |
| Dec. Position | -11:54:32 |
| Constellation | Eridanus |
| Distance | 4.65 billion light-years (z=0.441) |
| About The Data | |
| Data Description | The Hubble image was created with data from proposals (A. Linden), (D. Coe), and (M. Bradac). The Webb image was created with data from proposal: (C. Willott); Image Processing: Joseph DePasquale (STScI) |
| Instrument | Hubble: ACS; Webb: NIRCam |
| Filters | Hubble: F606W, F435W, F814W; Webb: F090W, F150W, F444W |
| About The Image | |
| Color Info | The Hubble image is a composite of separate exposures acquired by the ACS instrument on the Hubble Space Telescope. Several filters were used to sample various 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, Green=F606W, Red= F814W. Likewise, the Webb image is a composite of separate exposures acquired by the NIRCam instrument. 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: F090W Green: F150W Red: F444W |
| 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 | |
| Color Info | A brief description of the methods used to convert telescope data into the color image being presented. |
| Compass and Scale Image | An astronomical image with a scale that shows how large an object is on the sky, a compass that shows how the object is oriented on the sky, and the filters with which the image was made. |
