Pillars of creation, Lick Observatory, 2018 [RAW]
Having recently attended a workshop at the Lick Observatory and the opportunity to observe at the telescopes there, this is the raw data of the pillars of creation that we were able to capture using the Nickel Telescope whilst there.
Exposure time: 300 seconds
Location : M16 (Eagle Nebula)
This image needs to reduced even further to correct for the anomalies in
color that one can observe on the image and that’s something we are
currently working on. We hope to share the entire data with you in a month’s time after post-processing.
Have a good one!
The Pillars Of Creation Haven’t Been Destroyed, Say New NASA Images
“Near-infrared observations can see through the dust, revealing a glittering tapestry of young, hot stars inside. But at longer wavelengths, cooler-temperature objects show up. Mid-infrared light revealed that a diffuse heat source was warming the nebula, suggesting a recent supernova. While the far-infrared showed where the gas is evaporating, we needed X-rays to know if the pillars were being destroyed.”
In a stunning new release, NASA’s Chandra X-ray observatory has put out a wide-field view of a large portion of the Eagle Nebula, including the famed Pillars of Creation. All told, some 1,700 X-ray sources were identified, perhaps 2/3rds of which are inside the nebula. There are proto-stars, young stars, and stellar corpses. But conspicuously missing from the entire field-of-view is any evidence of a supernova remnant. In 2007, infrared data from Spitzer suggested that there may have been a recent supernova, and hence the pillars may already have been destroyed. The new Chandra data weighs in on that, giving a definitive “no” for an answer.

The Pillars Of Creation Haven’t Been Destroyed, After All
“Moreover, the best evidence for changes comes at the base of the pillars, indicating an evaporation time on the order of between 100,000 and 1,000,000 years. The idea that the pillars have already been destroyed has been demonstrated not to be true. It’s one of the great hopes of science that any controversial claims will be laid to rest by more and better data, and this is one situation where that has paid off in spades. Not only has there not been a supernova that’s in the process of destroying the pillars, but the pillars themselves should be robust for a long time to come.”
In 1995, NASA’s Hubble Space Telescope observed the Eagle Nebula, identifying the now-iconic pillars of creation, where newborn stars are forming inside a gas-rich, dusty region of space. Outside of those pillars, thousands of stars shine brightly, working to boil the gas off, while inside, the radiation from newly-formed stars works to boil it away from the inside. In 2007, the Spitzer Space Telescope, observing in the infrared, suggested that these pillars were blown apart thousands of years ago by a supernova, and that the light hadn’t simply reached our eyes yet. This was controversial, however, and follow-up observations would be required to know for certain. Well, the data has come in, and guess what?
The pillars of creation haven’t been destroyed after all, as the supernova seems to never have occurred. Instead of ~1,000 years, we should have hundreds of thousands of years before the pillars disappear completely. Come get the full story.
How Quickly Are The Pillars Of Creation Being Destroyed?
“The new image includes infrared data, which penetrates the dust, revealing stars and showcasing where the gas (in blue, above) is evaporating.
Changes between the images indicate that the pillars are still intact today, even though the light we’re seeing came from 7,000 years ago.
The best evidence for changes comes at the base of the pillars, indicating an evaporation time of approximately 100,000 years.”
Are the beautiful and iconic Pillars of Creation, located deep within the Eagle Nebula, still around today? At a distant of 7,000 light years, the Pillars could have been destroyed at any point from about 5,000 B.C. to the present, and we’d have no way of knowing. When they were first imaged in 1995, many speculated that the nebula, containing new stars and many supernova candidates, may have already destroyed these dusty structures by now. In 2007, a study by the Spitzer Space Telescope showed off some hot, glowing dust, perhaps indicating a supernova that took place some 8000-9000 years ago. But the most recent data from Hubble, in both the visible and infrared combined, not only teaches us that the supernova was an unlikely explanation for the dust, but allowed us to measure the true rate of evaporation of the Pillars themselves.
It looks like they’re not only still here today, but will likely be around for 100,000 years or more! Come find out the latest on the Pillars of Creation on today’s Mostly Mute Monday.
