What should you may stand in a hallway in an enormous constructing in New York Metropolis and really feel as should you’re within the middle of the universe?
Nicely, you may. “Eyes on the Universe: Images from Space Telescopes,” on the American Museum of Pure Historical past in Manhattan, is a jewel field exhibition of 14 images of supernovas, planets, galaxies and different astrophysical objects captured by three telescopes working in house. It opened earlier this 12 months and can run indefinitely.
It couldn’t be extra well timed. When two NASA astronauts splashed down in March after unexpectedly spending 9 months — as an alternative of 1 week — on the Worldwide Area Station, the general public was transfixed.
And with the expansion of personal house corporations, house tourism could be inside attain, no less than for the ultrawealthy.
The introductory {photograph} simply exterior the exhibition — greater than 5 ft throughout —- exhibits a visualization of knowledge from the Milky Manner galaxy that appears one thing like a wispy define of a mountain vary illuminated at midnight. It was taken by the Gaia telescope, which was launched in 2013 by the European Area Company and accomplished its mission in March.
What’s virtually inconceivable to grasp is what this picture represents: Gaia’s efforts to measure each particular person star — its place, its velocity and its brightness — in our galaxy, the Milky Manner, stated Mordecai-Mark Mac Low, a co-curator of the present. Thus far, he added, the Gaia has surveyed about one p.c of all the celebrities within the galaxy or a couple of billion stars.
Whereas there are dozens of house telescopes, the curators selected to make use of photos transmitted by three of the most important ones — the Gaia, the Hubble Area Telescope and the James Webb Area Telescope
They went by way of lots of of photos publicly obtainable by way of NASA, and the European Area Company, specializing in people who met no less than one among three standards: they provide various examples of human understanding of the universe, look good within the small hallway space, and have some connection to the museum’s personal house analysis.
Their analysis, Dr. Mac Low stated, on the broadest stage, is about “attempting to grasp how the solar and earth got here to be by finding out how stars kind, how galaxies kind, how the primary stars begin to generate heavy components. The iron in our blood comes from supernova — exploding stars. The hydrogen within the water got here from the Huge Bang. How did it get onto a planet, into us?”
On a way more particular — and relatable — stage, astrophysics helped result in the Nineteenth-century discovery that atoms emit completely different colours, which led to quantum mechanics, which led to an understanding of semiconductors.
“And that telephone in my pocket is totally depending on extraordinarily cautious investigations of semiconductors,” he stated.
A mural-like picture on the doorway exhibits a large pinkish and blue spiral in opposition to black with a brilliant yellow gentle in the course of the spiral. Stars within the middle are billions of years outdated, whereas these on the outer a part of the spiral are younger — solely tens of millions of years outdated.

Different images embody some 300,000 clusters of brilliantly glowing stars within the Milky Manner; one other that appears like a blue planet drifting in house, however is definitely a large bubble of gasoline and mud that measures seven gentle years throughout.
The exhibition additionally highlights how every telescope transmits photos otherwise. For instance, two images of what’s known as a barred spiral galaxy are positioned one above the opposite. The highest picture, from the Hubble Area Telescope, launched in 1990, makes use of seen gentle and exhibits what seems like a swirl of sunshine. The one beneath, of the identical galaxy, taken by the James Webb Area Telescope, launched in 2021, makes use of primarily infrared. It seems to be a circle of fireside.
Scorching stars emit seen gentle, whereas the chilly mud in house emits infrared gentle, thus the distinction in look.
The three telescopes ship completely different photos for quite a lot of causes — the place they’re, what they’re designed to {photograph} and the way highly effective they’re. The Hubble is in low orbit — about 300 miles above Earth. The Gaia was and the James Webb nonetheless is orbiting past the moon, at a degree the place the moon and earth’s gravity is about equal — about one million miles from earth.
The Gaia telescope was continually spinning in an effort to map the entire sky, Dr. Mac Low stated, whereas the Hubble and James Webb are pointed telescopes that seize pinpoints within the universe. The colours of all the photographs are enhanced; the astronomer processing the picture makes use of one thing akin to an Instagram filter “for some mixture of scientific worth and aesthetics, he stated.
His hope is that the exhibit will remind no less than some who stroll by that “the universe is a really huge place and perhaps get them to search for somewhat from their very own focus.”
