United States.- The National Aeronautics and Space Administration, better known as NASA for its acronym in English, revealed unpublished images of the constellation Orion, where “baby stars” are observed.
Tens of baby stars Enveloped in dust are revealed in this infrared image of the star-forming region NGC 2174, seen by NASA’s Spitzer Space Telescope.
Some of the clouds in the region resemble a monkey’s face in visible light images, hence the nebula’s nickname: “Monkey Head.”
However, in infrared images like this, the monkey disappears. This is because different clouds are highlighted in infrared and visible light images.

Found at the northern end of the constellation Orion, NGC 2174 is about 6,400 light years away. The dust plumes, slightly to the right of the center of the image, are being carved out of the dust by radiation and stellar winds from the hottest young stars recently born in the area.
Stars are born in Orion
Spitzer’s infrared view gives us a preview of the next star clusters that will be born in the next few millennia.
The reddish points of light scattered through the darkest filaments are young stars wrapped in blankets of warm dust. Hot dust glows at infrared wavelengths. Eventually, these stars will emerge from their dusty envelopes and their light will carve the dust clouds that surround them.
In this image first published in 2015, infrared wavelengths have been assigned visible colors that we see with our eyes. Light with a wavelength of 3.5 microns is displayed in blue, 8.0 microns in green, and 24 microns in red.

The greens show the organic molecules in the dust clouds, illuminated by starlight. Reds are caused by thermal radiation emitted by hotter dusty areas.
