WR 140.  This object is a binary star which exhibits very clear episodic dust formation due to colliding winds caused by the interaction of the binary pair. The observation of WR140 was part of an Early Release Science Program of the James Webb Space Telescope. The science paper on this paper by Lau etal 2022 is published in Nature. The image shows clearly the successive rings of dust - 17 in total. Dust ring production occurs every 7.93 years.

The top image on the left is the JWST MIRI image of WR140. False colors were assigned to the observations taken with the F770W, F1500W, and F2100W filters that correspond to blue, green, and red, respectivelyin the image.

The second image is a cleaned image produced by Dr R. Hurt of Caltech. The image has been cleaned of surrounding stellar images not connected to WR140, and the point spread function of JWST has been removed to clarify the structure of the dust shells surrounding the object. This image was used to create the tactile 3D print.

VV 191 Galaxy Pair

VV191 image and 3D print

VV191.  Two telescopes, NASA’s James Webb Space Telescope and NASA’s Hubble Space Telescope were used to image the VV 191 pair of galaxies. The data include near-infrared light from Webb, and ultraviolet and visible light from Hubble. The data show the light from the bright eliptical galaxy at the left and the structure of the spiral arms and dust lanes in the gaalaxy to the right. This observation was described on the NASA Webb Blog on October 5, 2022.

The second image image illustrates the Hubble + Webb image and its 3D tactile print.
