This image of comet C/2020 F3 (NEOWISE) was taken by the Hubble Space Telescope on August 8, 2020. Hubble’s image represents the first time a comet of this brightness has been photographed at such resolution after this close of a pass by the Sun.
The two structures appearing on the left and right sides of the comet’s center are jets made up of ice sublimating from beneath the surface of the nucleus, with the resulting dust and gas being squeezed through at a high velocity. The jets emerge as cone-like structures, then are fanned out by the rotation of comet NEOWISE’s nucleus.

|---|---|
| Object Name | C/2020 F3 NEOWISE |
| Object Description | Comet |
| Distance | At the time of observations, the comet was .966 AU from Earth (183 million miles). |
| About The Data | |
| Data Description | The HST observations include those from the Program (Q. Zhang). |
| Instrument | WFC3/UVIS and ACS/WFC |
| Exposure Dates | 8 August 2020 |
| Filters | F487N, F689M, F845M, F775W |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFC3 and 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: F487N Green: F689M Red: F845M Luminosity: 775W |
| 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. |
