NASA/ESA Hubble Home Telescope captured an image of two galaxies: NGC 4496A and NGC 4496B. The galaxies seem to live beside one yet any other in the constellation Virgo however maintain wide distances between them.
NGC 4496A is 47 million mild-years from Earth, whereas NGC 4496B is 212 million mild-years away. It map they need to now not interacting and easiest seem to overlap due to of enterprise alignment.
Probability galactic alignments provide astronomers a possibility to gaze the distribution of mud in these galaxies. By barely measuring how mud in the foreground galaxy impacts starlight from the background galaxy, astronomers can plan the mud in the foreground galaxy’s spiral palms.
The ensuing “mud maps” abet astronomers calibrate the whole lot from cosmological distances to the sorts of stars populating these galaxies.
