Scientists have combined data from two powerful telescopes to illuminate the dust in a distant galaxy pair.
After two images we shared last week showed how scientific knowledge can be increased by tools like the Hubble Space Telescope and the James Webb Space Telescope imaging the same target separately, this week sees a project in which data from the two telescopes has been brought together.
Hubble observes primarily in the visible light and ultraviolet portions of the electromagnetic spectrum, while Webb looks at the infrared range which is beyond human vision. In pairing up data from both telescopes, researchers used Hubble data for bluish tones in the image and Webb data to pick up on the dust features.
That included some surprising findings, like a red smudge to the northwest position of the left-hand galaxy. That smudge is actually another extremely distant galaxy, which has been magnified and distorted in a phenomenon called gravitational lensing. You can even just about see its reflection as a dot at the southeast position relative to the foreground galaxy.
