The Pillars of Creation: The Star Formation Marvelously Portrayed by James Webb | Digital Trends Spanish


An impressive and beautiful image gives us again the James Webb Space Telescopewho provided an extremely detailed and beautifully colored record of “The Pillars of Creation,” where new stars form within dense clouds of gas and dust.

“Three-dimensional pillars look like majestic rock formations, but they are much more permeable. These plumes are made up of fresh interstellar gas and dust that are sometimes semi-transparent in near-infrared light.

Newly formed stars take center stage in this image from Webb’s Near Infrared Camera (NIRCam). These are the bright red orbs that typically have diffraction spikes and are found outside of one of the dust pillars. When massive enough knots form within the pillars of gas and dust, they begin to collapse under their own gravity, slowly heat up, and ultimately form new stars.

And what about those wavy lines that look like lava on the edges of some pillars? These are ejecta from stars that are still forming within the gas and dust. Young stars periodically launch supersonic jets that collide with clouds of material, such as these thick pillars. This also sometimes causes shock waves, which can form undulating patterns like a ship moving through water. The crimson glow comes from energetic hydrogen molecules that are produced by the jets and shock waves.
