At the American Museum of Natural History, a Look to Outer Space

This article is part of our Museums special section about how artists and institutions are adapting to changing times.


What if you could stand in a hallway in a huge building in New York City and feel as if you’re in the center of the universe?

Well, you can. “Eyes on the Universe: Images from Space Telescopes,” at the American Museum of Natural History in Manhattan, is a jewel box exhibition of 14 photographs of supernovas, planets, galaxies and other astrophysical objects captured by three telescopes operating in space. It opened earlier this year and will run indefinitely.

It couldn’t be more timely. When two NASA astronauts splashed down in March after unexpectedly spending nine months — instead of one week — on the International Space Station, the public was transfixed.

And with the growth of private space companies, space tourism might be within reach, at least for the ultrawealthy.

The introductory photograph just outside the exhibition — more than five feet across —- shows a visualization of data from the Milky Way galaxy that looks something like a wispy outline of a mountain range illuminated in the dark. It was taken by the Gaia telescope, which was launched in 2013 by the European Space Agency and completed its mission in March.

What’s almost impossible to comprehend is what this image represents: Gaia’s efforts to measure every individual star — its position, its velocity and its brightness — in our galaxy, the Milky Way, said Mordecai-Mark Mac Low, a co-curator of the show. So far, he added, the Gaia has surveyed about one percent of all the stars in the galaxy or about a billion stars.

While there are dozens of space telescopes, the curators chose to use images transmitted by three of the major ones — the Gaia, the Hubble Space Telescope and the James Webb Space Telescope

They went through hundreds of images publicly available through NASA, and the European Space Agency, focusing on those that met at least one of three criteria: they offer varied examples of human understanding of the universe, look good in the small hallway area, and have some connection to the museum’s own space research.

Their research, Dr. Mac Low said, at the broadest level, is about “trying to understand how the sun and earth came to be by studying how stars form, how galaxies form, how the first stars start to generate heavy elements. The iron in our blood comes from supernova — exploding stars. The hydrogen in the water came from the Big Bang. How did it get onto a planet, into us?”

On a much more specific — and relatable — level, astrophysics helped lead to the 19th-century discovery that atoms emit different colors, which led to quantum mechanics, which led to an understanding of semiconductors.

“And that phone in my pocket is completely dependent on extremely careful investigations of semiconductors,” he said.

A mural-like image on the doorway shows a giant pinkish and blue spiral against black with a bright yellow light in the middle of the spiral. Stars in the center are billions of years old, while those on the outer part of the spiral are young — only millions of years old.

Viewers can use a QR code to view a model of how this galaxy formed.

Other photographs include some 300,000 clusters of brilliantly sparkling stars in the Milky Way; another that looks like a blue planet drifting in space, but is actually a giant bubble of gas and dust that measures seven light years across.

The exhibition also highlights how each telescope transmits images differently. For example, two photographs of what is called a barred spiral galaxy are positioned one above the other. The top image, from the Hubble Space Telescope, launched in 1990, uses visible light and shows what looks like a swirl of light. The one below, of the same galaxy, taken by the James Webb Space Telescope, launched in 2021, uses primarily infrared. It appears to be a circle of fire.

Hot stars emit visible light, while the cold dust in space emits infrared light, thus the difference in appearance.

The three telescopes send different images for a variety of reasons — where they are, what they are designed to photograph and how powerful they are. The Hubble is in low orbit — about 300 miles above Earth. The Gaia was and the James Webb still is orbiting beyond the moon, at a point where the moon and earth’s gravity is about equal — about a million miles from earth.

The Gaia telescope was constantly spinning in an effort to map the whole sky, Dr. Mac Low said, whereas the Hubble and James Webb are pointed telescopes that capture pinpoints in the universe. The colors of all the images are enhanced; the astronomer processing the image uses something akin to an Instagram filter “for some combination of scientific value and aesthetics, he said.

His hope is that the exhibit will remind at least some who walk by that “the universe is a very big place and maybe get them to look up a little from their own focus.”

Engineer Is First Paraplegic Person in Space

A paraplegic engineer from Germany became the first wheelchair user to rocket into space. The small craft that blasted her to the edge of space was operated by Jeff Bezos’ company Blue Origin.

Capsule touchdown. There’s CM 7 Sarah Knights and Jake Mills. They’re going to lift Michi down into the wheelchair, and she has completed her journey to space and back.

This City’s Best Winter Show Is in Its Pitch-Dark Skies
Flagstaff mandates that shielding be placed on outdoor lighting so that it doesn’t project skyward. There are also limits on the lumens of light allowed per acre of land.

The result is a starry sky visible even from the heart of the city. Flagstaff’s Buffalo Park, just a couple miles from downtown, measures about a 4 on the Bortle scale, which quantifies the level of light pollution. (The scale goes from 1, the darkest skies possible, to 9, similar to the light-polluted night sky of, say, New York City. To see the Milky Way, the sky must be below a 5.)

Social media users in the Central Valley are freaking out about unusual fog, and what might be in it

Social media users in the Central Valley are freaking out about unusual fog, and what might be in it

A 400-mile blanket of fog has socked in California’s Central Valley for weeks. Scientists and meteorologists say the conditions for such persistent cloud cover are ripe: an early wet season, cold temperatures and a stable, unmoving high pressure system.

But take a stroll through X, Instagram or TikTok, and you’ll see not everyone is so sanguine.

People are reporting that the fog has a strange consistency and that it’s nefariously littered with black and white particles that don’t seem normal. They’re calling it “mysterious” and underscoring the name “radiation” fog, which is the scientific descriptor for such natural fog events — not an indication that they carry radioactive material.

An X user with the handle Wall Street Apes posted a video of a man who said he is from Northern California drawing his finger along fog condensate on the grill of his truck. His finger comes up covered in white.

“What is this s— right here?” the man says as the camera zooms in on his finger. “There’s something in the fog that I can’t explain … Check y’all … y’all crazy … What’s going on? They got asbestos in there.”

Another user, @wesleybrennan87, posted a photo of two airplane contrails crisscrossing the sky through a break in the fog.

“For anyone following the dense Tule (Radiation) fog in the California Valley, it lifted for a moment today, just to see they’ve been pretty active over our heads …” the user posted.

Scientists confirm there is stuff in the fog. But what it is and where it comes from, they say, is disappointingly mundane.

The Central Valley is known to have some of the worst air pollution in the country.

And “fog is highly susceptible to pollutants,” said Peter Weiss-Penzias, a fog researcher at UC Santa Cruz.

Fog “droplets have a lot of surface area and are suspended in the air for quite a long time — days or weeks even — so during that time the water droplets can absorb a disproportionate quantity of gasses and particles, which are otherwise known as pollutants,” he said.

He said while he hasn’t done any analyses of the Central Valley fog during this latest event, it’s not hard to imagine what could be lurking in the droplets.

“It could be a whole alphabet soup of different things. With all the agriculture in this area, industry, automobiles, wood smoke, there’s a whole bunch” of contenders, Weiss-Penzias said.

Reports of the fog becoming a gelatinous goo when left to sit are also not entirely surprising, he said, considering all the airborne biological material — fungal spores, nutrients and algae — floating around that can also adhere to the Velcro-like drops of water.

He said the good news is that while the primary route of exposure for people of this material is inhalation, the fog droplets are relatively big. That means when they are breathed in, they won’t go too deep into the lungs — not like the particulate matter we inhale during sunny, dry days. That stuff can get way down into lung tissue.

The bigger concern is ingestion, as the fog covers plants or open water cisterns, he said.

So make sure you’re washing your vegetables, and anything you leave outside that you might nosh on later.

Dennis Baldocchi, a UC Berkeley fog researcher, agreed with Weiss-Penzias’ assessment, and said the storm system predicted to move in this weekend will likely push the fog out and free the valley of its chilly, dirty shawl.

But, if a high pressure system returns in the coming weeks, he wouldn’t be surprised to see the region encased in fog once again.
