In the mid-1800s, buildings were limited by one thing: stairs. Climbing more than a few flights was impractical, which meant cities could only grow outward, not upward. But that all changed in 1853 when a man named Elisha Otis introduced a revolutionary invention—the elevator safety brake.

Before Otis, elevators existed, but they were dangerously unreliable. A snapped rope could mean certain death. Otis solved this with a mechanical safety device that stopped the elevator from falling if the cable failed. To prove his invention worked, he staged a dramatic demonstration at the New York World’s Fair: he stood on a platform, ordered the rope cut, and… nothing happened. The brake caught the elevator. The crowd gasped. History shifted.

Otis founded the Otis Elevator Company, which still powers many of the world’s tallest buildings today. His invention didn’t just make elevators safe—it made the modern skyline possible. Skyscrapers, as we know them, owe their existence to that bold moment and a man who believed cities should grow up, not out.

Without Otis, we’d still be climbing stairs.

A swarm of earthquakes has been rattling Southern California near the Salton Sea, drawing attention from residents and seismologists across the region.

Salton Sea earthquake swarm?

The activity is centered near Brawley in Imperial County, an area known for frequent seismic movement due to its location within the Brawley Seismic Zone. According to the U.S. Geological Survey, hundreds of small earthquakes have been recorded over the past several days, with the strongest reaching a magnitude of approximately 4.7.

Residents throughout Imperial Valley, parts of Riverside County, and even portions of Arizona reported feeling shaking from several of the larger quakes. Minor incidents such as falling objects and brief power disruptions were also reported, though no major injuries or widespread structural damage have been confirmed at this time.

The region sits near the southern end of the San Andreas Fault and is considered one of California’s most geologically active areas. Scientists say earthquake swarms are relatively common near the Salton Sea because of the interaction between tectonic fault systems and geothermal activity beneath the surface.

While experts continue to monitor the situation closely, they emphasize that earthquake swarms do not necessarily indicate that a larger earthquake is imminent. However, officials encourage residents to review emergency preparedness plans, secure heavy furniture, and keep emergency supplies ready.

The Salton Sea region has experienced similar seismic swarms in the past, making it an important area of study for earthquake researchers and emergency management agencies.

In early April 2026, the Artemis II mission captivated me and millions of people watching from across the world. The crew’s courage, skill and infectious wonder served as tangible proof of human persistence and technological achievement, all against the mysterious backdrop of space.

People back on Earth got to witness the mission through remarkable photos of space captured by astronauts. Images created and shared by astronauts underscore how photography builds a powerful, authentic connection that goes beyond what technology alone can capture.

As a photographer and the director of the Rochester Institute of Technology’s School of Photographic Arts and Sciences, I am especially drawn to how these photographs have been at the center of the public’s collective experience of this mission.

In an era when image authenticity is often questioned and with the capabilities of autonomous, AI-driven imaging, NASA’s choice to train astronauts in photography has placed meaning over convenience and prioritized their human perspectives and creativity.

Capturing space from the crew’s perspective

Photography was not originally placed as a high priority in NASA’s Apollo era. The astronauts only took photographs if they had the chance and all their other tasks were complete.

Thanks largely in part to public response to those images from Apollo, including “Earthrise” and the “Blue Marble” being widely credited for helping catalyze the modern environmental movement, NASA shifted its approach to utilize photography to help capture the public’s imagination by training their astronauts in photographic practices.

The Artemis II mission’s photographs have helped cut through the increasing volume of artificially generated images circulating on social media. NASA’s social media releases of the crew’s photographs have garnered thousands of shares and comments.

This excitement could be explained by the novelty of photos from space, but these images also distinguish themselves as products of astronauts experiencing these sights and interpreting them through their photographs. These differences require an important distinction around where technology ends and humanity begins.

Human perspective versus AI tools

Photography has long integrated AI-powered software and data-driven tools in a variety of ways: to process raw images, fill in missing color information, drive precise focus and guide image editing, among others. These modern technological assists help human photographers realize their vision.

Artificial intelligence is also increasingly capable of operating machinery competently and autonomously, from cars to drones and cameras.

And AI can generate convincing, realistic images and videos from nothing more than a text prompt, using readily available tools.

Researchers train AI to mimic patterns informed by millions of sample images, and the algorithm can then either take or create a photograph based on what it predicts would be the most likely version of a successful, believable image.

Human-created photos are rooted in direct observation, intent and lived experience, while AI images – or choices made by AI-driven tools – are not. While both can produce compelling and believable visuals, the human photographs carry emotional power because the photographer is drawing from their experiences and perspective in that moment to tell an authentic story.

Artemis II photographs resonate, not only because they are historic, but because they reflect the deliberate choices and intent of a human being in that specific moment and context. The exposure, camera setting, lens choice and composition are all dictated by the astronaut’s vision, skill, perspective and experience. Each image is unique in comparison with the others. These choices give the images narrative power, anchoring them in human perspective.

Images to tell a story

Photographers choose what to include in the final version of their image to tell a story. In the Artemis II images, this human perspective comes out. In the “Earthset” photo, you see a striking juxtaposition of the Moon’s monochromatic, textured surface in the foreground against a slivered, bright Earth.

The choice to include both in the frame contrasts these objects literally and figuratively, inviting comparison. It creates a narrative where Earth is contrasted against the Moon – life is contrasted against the absence of it.

Another photo shows the nightside of the whole Earth, featuring the Sun’s halo, auroras and city lights. The choice to include the subtle framing of the window of the capsule in the lower left corner reminds the viewer where and how this image was captured: by a human, inside a capsule, hurtling through space. That detail grounds the photograph in the human perspective.

Both photos are reminiscent of Earthrise and the Blue Marble. These past images hold a place in the global collective consciousness, shaped by a shared historical moment.

The Artemis II photographs are anchored in this collective moment of lived human experience, yet also shaped by each astronaut’s viewpoint. The crew’s unique perspectives exemplify photography’s transformative power by inviting viewers to engage emotionally and intellectually with their journey. These photographs share the astronauts’ awe and wonder and affirm the value of human creativity and its ability to connect us in a captured moment.
