NASA’s Universe of Learning – a partnership among the Space Telescope
Science Institute (STScI), Caltech/IPAC, the Center for Astrophysics | Harvard
& Smithsonian, and the Jet Propulsion Laboratory and part of the NASA
Science Activation program portfolio – recently released a new 3D
visualization of the towering clouds of cosmic dust and gas at the center of the
star-forming region known as M16, or the Eagle Nebula. This video, which uses
data from NASA’s Hubble, James Webb, and Spitzer space telescopes, as well as
the Chandra X-ray Observatory, is the most comprehensive and detailed
multiwavelength movie yet of these star-birthing “Pillars of Creation.”
“By flying past and amongst the
pillars, viewers experience their three-dimensional structure and see how they
look different in the Hubble visible light view versus the Webb infrared light
view,” explained principal visualization scientist Frank Summers of STScI in
Baltimore. “The contrast helps them understand why we have more than one space
telescope to observe different aspects of the same object.” Summers led the
video development team.
The Pillars of Creation, made
primarily of cool molecular hydrogen and dust, are being eroded by the fierce
winds and punishing ultraviolet light of nearby hot, young stars. Finger-like
structures larger than the solar system protrude from the tops of the pillars.
Within these fingers can be embedded embryonic stars. The tallest pillar
stretches across three light-years, three-quarters of the distance between our
Sun and the next nearest star.
The movie takes visitors into the
three-dimensional structures of the pillars. Rather than an artistic
interpretation, the video is based on observational data from a science paper
led by Anna McLeod, an associate professor at the University of Durham in the
United Kingdom. McLeod also served as a scientific advisor on the movie
project.
The 3D structures are
approximations for how the pillars are lined up in space like a row of trees,
based on observational data. The goal is to give viewers an experiential view,
so that they can better interpret the otherwise flat, two-dimensional images
from telescopes. This 3D understanding allowed the team to create 3D printable
files of the Pillars using the newest data.
On the same day or the
visualization release, Dr. Frank Summers led a live-streamed panel discussion
with attendees covering "A Deep Dive into the Creation of the Pillars of
Creation" at the AstroViz Community Practice meetup. The panelists and
attendees engaged in a deep dive into the transformation of 2D views of the
Pillars of Creation into a scientifically-vetted 3D visualization.
The new visualization helps viewers
experience how of the world’s most powerful space telescopes work together to
provide a more complex portrait of the pillars. Hubble sees objects that glow
in visible light at thousands of degrees. Webb’s infrared vision, which is
sensitive to cooler objects with temperatures of just hundreds of degrees,
pierces through obscuring dust to see stars embedded in the pillars.
