This zoom into VY Canis Majoris is a combination of Hubble imaging and an artist's impression. The left panel is a multicolor Hubble image of the huge nebula of material cast off by the hypergiant star. This nebula is approximately a trillion miles across. The middle panel is a close-up Hubble view of the region around the star. This image reveals close-in knots, arcs, and filaments of material ejected from the star as it goes through its violent process of casting off material into space. VY Canis Majoris is not seen in this view, but the tiny red square marks the location of the hypergiant, and represents the diameter of the solar system out to the orbit of Neptune, which is 5.5 billion miles across. The final panel is an artist's impression of the hypergiant star with vast convection cells and undergoing violent ejections. VY Canis Majoris is so large that if it replaced the Sun, the star would extend for hundreds of millions of miles, to between the orbits of Jupiter and Saturn.

| About The Data | |
| Data Description | The Hubble image was created from HST data from proposals: (R. Humphreys) |
| Instrument | WFPC2 |
| Exposure Dates | 22 March 1999, 13 June 2005 |
| Filters | F410M, F547M, F656N, F1042M |
| About The Image | |
| Color Info | These images are a composite of separate exposures acquired by the WFPC2 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: F410M Green: F547M Orange: F656N Red: F1042M |
