Editor's Note: This article focuses on data from Weber Science Advances, which have not yet been peer reviewed. Here, Interdisciplinary scientist Roger Windhorst and his team discuss their observations.
" By combining data from NASA 's James Webb Space Telescope and Hubble Space Telescope, we get something unexpected! Webb's new data allows us to track the light emitted by the bright white elliptical galaxy on the left, pass through the curved spiral galaxy on the right, and identify the effects of interstellar dust in the spiral galaxy. This VV Images of 191 galaxy pairs include near-infrared light from Weber, as well as ultraviolet and visible light from Hubble .

"Weber's Near infrared data also shows us more details of the longer, extremely dusty spiral arms of the galaxy, making these spiral arms appear to overlap the central bump of the bright white elliptical galaxy on the left. Although the two prospective galaxies are relatively close astronomy, they do not actively interact with each other.
"VV 191 is the latest member of a handful of galaxies, which can help researchers like us directly compare the properties of galaxy dust. This goal is to pick out the Galaxy Zoo citizen science volunteers from nearly 2,000 overlapping pairs of galaxies.
"It is important to understand the position of dust in galaxies, because dust changes the brightness and color that appears in galaxy images. Dust particles are partly responsible for the formation of new stars and planets, so we have been seeking to determine their existence for further research.


Above the white elliptical galaxy on the left, a faint red arc appears in the illustration at 10 o'clock. This is a very distant galaxy and its appearance is distorted. Its light is bent by the gravity of the elliptical foreground galaxy. Plus, its appearance is replicated. The stretched red arc will bend into a point when it reappears at 4 o'clock. In this image, green, yellow and red are assigned to Webb's near-infrared data captured at 0.9, 1.5 and 3.56 microns (F090W, F150W and F356W, respectively). Blue is assigned to two Hubble filters, UV data at 0.34 microns (F336W) and visible light data at 0.61 microns (F606W).

"This image contains a second discovery that is more easily overlooked. Check the white elliptical galaxy on the left. A faint red arc appears in the illustration at the 10 o'clock position. It is a very distant galaxy whose light is bent by the gravity of the elliptical foreground galaxy--its appearance is replicated. The stretched red arc will bend into a point when it reappears at 4 o'clock. The images of these lens galaxies are too dark and red to be recognized in Hubble data, but they cannot be mistaken in Webber's near-infrared images.The simulated gravitational lenses like this help us reconstruct the mass of a single star, and how much dark matter is at the core of this galaxy.
"Like many Weber images, this VV 191 image shows an additional galaxy that is getting deeper and deeper in the background. The two irregular spirals in the upper left corner of the elliptical galaxy have similar apparent dimensions, but the colors are very different. One is likely to be dusty, and the other is very far away, but we – or other astronomers – need to get what is called a spectrum to tell which is which.”
