The Hubble telescope took a picture of the twin galaxies NGC 4496A and NGC 4496B.

Both galaxies are in the constellation Virgo. Judging by the image, NGC 4496A and NGC 4496B appear to be very close to each other, but the objects are actually far away.

NGC 4496A is located at a distance of 47 million light years from Earth. Supernova SN 1960F type Ia has exploded in the galaxy. Its peak apparent magnitude was 11.6. And NGC 4496B is 212 million light years away. Therefore, objects cannot interact.

They are nearby only because of a random alignment – with it you can study the distribution of dust in galaxies. Galactic dust looks beautiful in photographs – it can be seen in this image as dark curls located in NGC 4496A and NGC 4496B.

But dust also makes it difficult for astronomers to observe, it absorbs starlight and makes stars dimmer. Astronomers measure how starlight from background galaxies affects dust in intermediate galaxies. Next, they plot the location of the dust on the map. This data helps researchers to calibrate observation devices.
