THE PILLARS OF CREATION 😊

 

what you think about pillars of creation? what is a pillar of creation? where is the pillar of creation? 

Pillars of creation is a photograph taken by the Hubble Space Telescope of elephant trunks of interstellar gas and dust in the Eagle nebula, specifically the Serpens constellation, some 6,500 - 7,000 light-years from earth. they are so named because the gas and dust are in the process of creating new stars, while also being eroded by the light from nearby stars that have recently formed. taken in April1,1995, it was named one of the top ten photographs from Hubble. the astronomer responsible for the photo was Jeff Hester and Paul Scowen from Arizona state university. the region was rephotographed by ESA's Herschel Space Observatory in 2011, and by Hubble in 2014 with a newer camera. 

The pillars are composed of cool molecular hydrogen and dust that are being eroded by photoevaporation from the ultraviolet light of relatively close and hot stars. the leftmost pillar is about four light-years in length. the finger-like protrusions at the top of the clouds are larger than our solar system and are made visible by the shadows of evaporating gaseous globules (EGGs), which shield the gas behind them from intense UV flux. EGGs are themselves incubators of new stars. the stars then emerge from the EGGs, which then are evaporated.

Composition:-

The pillars are composed of cool molecular hydrogen and dust that are being eroded by photoevaporation from the ultraviolet light of relatively close and hot stars. the leftmost pillar is about four light-years in length. the finger-like protrusions at the top of the clouds are larger than our solar system and are made visible by the shadows of evaporating gaseous globules (EGGs), which shield the gas behind them from intense UV flux. EGGs are themselves incubators of new stars. the stars then emerge from the EGGs, which then are evaporated. 

Theorized destruction:-

Images were taken with the Spitzer Space Telescope uncovered a cloud of hot dust in the vicinity of the pillars of creation that Nicolas Flagey accounted to be a shock wave produced by a supernova. the appearance of the cloud suggests the supernova shockwave would have destroyed the pillars of creation 6,000 years ago. given the distance of roughly 7,000 light-years to the pillars of creation, this would mean that they have actually already been destroyed, but because light travels at a finite speed, this destruction should be visible from earth in about 1,000 years. however, this interpretation of the hot dust has been disputed by an astronomer uninvolved in the Spitzer observations, who argues that a supernova should have resulted in stronger radio and x-ray radiation than has been observed and that winds from massive stars could instead have heated the dust. 

The pillar of creation hasn't been destroyed:-

In 1995, the Hubble Space Telescope snapped one of the most iconic images of all-time: the framed "Pillars Of Creation" in the Eagle Nebula. one of the galaxy's closest and most productive regions of active star formation, these pillars represent what's left of the neutral gas that powers the creation of this new stars. but new stars aren't just a cosmic signpost of creation; they also bring destruction with them. when you form new stars, a fraction of them will be massive enough to go supernova, with these catastrophic explosions rapidly burning off and expelling the gas around them. others will burn fantastically hot, evaporating this gas more slowly. what we're seeing, inside this nebula, is a mix of these two processes. years ago, a NASA study claimed that a supernova recently occurred inside and that the pillars were already destroyed.

 At 7,000 light-years away, the Eagle Nebula is one of the night sky's most accessible and spectacular nebulae. it was discovered back in 1745, and shortly thereafter was recognized to be an active star-forming region, as the surefire signature of ionized hydrogen was seen in abundance. a large cluster of newborn stars can be found inside, consisting of over 8,000 stars, which is the primary cause of the nebula's shape. these stars, burning bright, emit copious amounts of ultraviolet light, which effectively ionizes and boils off the neutral gas.

When were the pillars of creation taken? :- 

The Hubble Space Telescope almost didn't make it. carried aloft in 1990 aboard the space shuttle Discovery, it was over-budget, years behind schedule and, when it finally reached orbit, nearsighted, its 8-foot mirror distorted as a result of a manufacturing flaw. it would not be until 1993 that a repair mission would bring Hubble online. finally, on April1, 1995, the telescope delivered the goods, capturing an image of the universe so clear and deep that it has come to be known as Pillars Of Creation. what Hubble photographed is the Eagle Nebula, a star-forming patch of space 6,500 light-years from earth in the constellation Serpens Cauda. the great smokestacks are vast clouds of interstellar dust, shaped by the high-energy winds blowing out from nearby stars (the black portion in the top right is from the magnification of one of Hubble's four cameras). but the science of the pillars has been the lesser part of their significance. both the oddness and the enormousness of the formation-the pillars are 5 light-years, or 30 trillion miles, longawed, thrilled, and humbled in equal measure. one image achieved what a thousand astronomy symposia never could.

" Pillars of Creation" region in Eagle Nebula:-

Images taken by Jeff Hester and Paul Scowen using the Hubble Space Telescope in 1995 greatly improved scientific understanding of processes inside the nebula. one of these photographs become famous as the "Pillars Of Creation", depicting a large region of star formation. the small dark areas in the photograph are believed to be protostars (Bok globules). the pillar structure of the region resembles region in the soul nebula of Cassiopeia, imaged with the Spitzer Space Telescope. 

That's it. so, now, what you think about "Pillar Of Creation" after reading this blog? comment in below its helpful for you or exciting? This blog is dedicated to my lovely and kind-hearted sister and this is she's favorite nebula! she helped a lot and I'm very honored to have as my dear sister. she's good name is Georgina.
