The latest image from this magnificent telescope shows the spiral galaxy NGC 5086. Scientists call it “stripe” because its hallmark is the bright band that runs through its center.
What is hidden under the veil?
Conventional photography will record a cloud of dust in this place, hiding cosmic secrets. So the telescope took advantage of the ability to record electromagnetic waves outside the spectrum seen by humans. The photo below was created thanks to combining two images – one was registered by MIRI (Mid-Infrared Instrument), the second by NIRCam (Near Infrared Camera). From the perspective of an Earthling, these instruments can be said to register heat rather than image. It is also worth bearing in mind that the pictures have already been colored on Earth.

The above image shows a galaxy 20 million light years from Earth. From our perspective, it is in the constellation of Virgo (Virgo). By being able to peer behind the veil of cold dust, scientists can observe a unique process – the birth of a star. In fact, even a few, because “currently” (I remind you that electromagnetic waves from this area have been rushing to us for about 20 million years) more than one is forming there.
It is also worth looking at the individual images from which an impressive photo was created. The one recorded by MIRI (above) beautifully shows the structure of the galaxy and the “bubbles”, i.e. young stars. NIRCam (below) captured an impressive band of older stars.
