(NASA, ESA, CSA, STScI via AP) Associated Press NASA’s most recent James Webb Space Telescope images of the Pillars of Creation, better known to astronomers as M16 in the Eagle Nebula, are enough to leave most anyone speechless. The iconic first Hubble images of this star-forming region were so astounding at the time that they produced a cottage industry of pillar kitsch —- from calendars to coffee cups. But scientifically, the most recent images released by NASA today show a close-up view of stars in full birth mode inside these dusty towers of creation.

To most, they remain pretty pictures to marvel over. Yet for professional astronomers they offer a cornucopia of untold scientific data to pore over for years to come. Many thousands of stars have formed in these Pillars of Creation, which are actually three giant columns of cold gas bathed in the scorching ultraviolet light from a cluster of young, massive stars, says NASA.

Located in a small region of the Eagle Nebula, or M16, some 6500 light years away, the pillars, flush with gas and dust, enshroud stars that are slowly forming over many millennia, NASA notes. In the James Webb Space Telescope’s most recent images, its Mid-Infrared Instrument (MIRI), many of the newly formed stars appear missing, says NASA. That’s actually due to the fact that many of these newly-formed stars are simply no longer surrounded by enough dust to be detected in the mid-infrared spectrum, NASA notes.

That’s because massive stars weather away their birth environments of dust and gas through their emission of extreme ultraviolet radiation as well as powerful stellar winds. The fingerlike shape of the pillars is produced by expanding bubbles of gas and dust, sculpted by evaporation caused by ionizing radiation. Stellar winds and a barrage of charged particles from the central star cluster located above the pillars also ablate this region, says NASA.

But with more powerful telescopes like Webb, theorists will better understand these processes. The Eagle Nebula lies several thousand light years distant and heretofore has not revealed the detail of its star formation as readily as the Orion Nebula, which lies only 1300 light years distant and is the nearest and most studied star-forming region to Earth.

Although astronomers know that the brightest and most massive stars out there are short lived, and typically live on timescales of only a few million years, most stars in the universe appear to be lower mass red dwarfs. These M-spectral type stars can continue their lives as hydrogen-burning main sequence stars for tens of billions of years. The hope among researchers is that the data that Webb is producing will enable researchers to better understand the makeup and the dynamics of the dust that lies within this iconic region of the Eagle Nebula.

Over time, we will begin to more clearly understand how stars form and burst out of these dusty clouds over millions of years, reports the European Space Agency (ESA). Because supernovae are only produced by massive stars, our own Sun most likely had its beginnings as part of a beguiling, but violent nebula that probably looked a lot like the Pillars of Creation. In essence, NASA’s Webb has given us exquisite snapshots of the kind of turmoil from which our own star must have emerged some 4.
