A Martian dust devil can be seen consuming its smaller friend in this short video made of images taken at the rim of Jezero Crater by NASA’s Perseverance Mars rover on Jan. 25, 2025. NASA/JPL-Caltech/SSI The six-wheeled explorer recently captured several Red Planet mini-twisters spinning on the rim of Jezero Crater.
A Martian dust devil can be seen consuming a smaller one in this short video made of images taken by a navigation camera aboard NASA’s Perseverance Mars rover. These swirling, sometimes towering columns of air and dust are common on Mars. The smaller dust devil’s demise was captured during an imaging experiment conducted by Perseverance’s science team to better understand the forces at play in the Martian atmosphere.
When the rover snapped these images from about 0.6 miles (1 kilometer) away, the larger dust devil was approximately 210 feet (65 meters) wide, while the smaller, trailing dust devil was roughly 16 feet (5 meters) wide. Two other dust devils can also be seen in the background at left and center. Perseverance recorded the scene Jan. 25 as it explored the western rim of Mars’ Jezero Crater at a location called “Witch Hazel Hill.”
“Convective vortices — aka dust devils — can be rather fiendish,” said Mark Lemmon, a Perseverance scientist at the Space Science Institute in Boulder, Colorado. “These mini-twisters wander the surface of Mars, picking up dust as they go and lowering the visibility in their immediate area. If two dust devils happen upon each other, they can either obliterate one another or merge, with the stronger one consuming the weaker.”
While exploring the rim of Jezero Crater on Mars, NASA’s Perseverance rover captured new images of multiple dust devils in January 2025. These captivating phenomena have been documented for decades by the agency’s Red Planet robotic explorers.

Dust devils are formed by rising and rotating columns of warm air. Air near the planet’s surface becomes heated by contact with the warmer ground and rises through the denser, cooler air above. As other air moves along the surface to take the place of the rising warmer air, it begins to rotate. When the incoming air rises into the column, it picks up speed like a spinning ice skater bringing their arms closer to their body. The air rushing in also picks up dust, and a dust devil is born.
“Dust devils play a significant role in Martian weather patterns,” said Katie Stack Morgan, project scientist for the Perseverance rover at NASA’s Jet Propulsion Laboratory in Southern California. “Dust devil study is important because these phenomena indicate atmospheric conditions, such as prevailing wind directions and speed, and are responsible for about half the dust in the Martian atmosphere.”
NASA’s Viking 1 orbiter captured this Martian dust devil casting a shadow on Aug. 1, 1978. During the 15-second interval between the two images, the dust devil moved toward the northeast (toward the upper right) at a rate of about 59 feet (18 meters) per second. NASA/JPL-Caltech/MSSS Since landing in 2021, Perseverance has imaged whirlwinds on many occasions, including one on Sept. 27, 2021, where a swarm of dust devils danced across the floor of Jezero Crater and the rover used its SuperCam microphone to record the first sounds of a Martian dust devil.
NASA’s Viking orbiters, in the 1970s, were the first spacecraft to photograph Martian dust devils. Two decades later, the agency’s Pathfinder mission was the first to image one from the surface and even detected a dust devil passing over the lander. Twin rovers Spirit and Opportunity managed to capture their fair share of dusty whirlwinds. Curiosity, which is exploring a location called Mount Sharp in Gale Crater on the opposite side of the Red Planet as Perseverance, sees them as well.
Capturing a dust devil image or video with a spacecraft takes some luck. Scientists can’t predict when they’ll appear, so Perseverance routinely monitors in all directions for them. When scientists see them occur more frequently at a specific time of day or approach from a certain direction, they use that information to focus their monitoring to try to catch additional whirlwinds.
“If you feel bad for the little devil in our latest video, it may give you some solace to know the larger perpetrator most likely met its own end a few minutes later,” said Lemmon. “Dust devils on Mars only last about 10 minutes.”
More About Perseverance
A key objective of Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. The rover is characterizing the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet and as the first mission to collect and cache Martian rock and regolith.
NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Mars Exploration Program (MEP) portfolio and the agency’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech, built and manages operations of the Perseverance rover.

On the night of February 23, 2025, residents of Tucumán, Argentina witnessed an astonishing sight during a violent thunderstorm. As a powerful lightning bolt tore through the sky, it briefly illuminated a massive, cigar-shaped object hovering in the storm’s center.
Eyewitnesses described the object as dark, elongated, and solid, standing in stark contrast to the swirling storm clouds around it. Unlike a natural weather phenomenon, the shape appeared structured and deliberate, leading many to speculate that it was a UFO of intelligent design, possibly of extraterrestrial origin.
It is not clear whether the object was struck by the lightning but there have been reports of UFOs being hit by lightning yet remaining unaffected, suggesting they may either harness or withstand immense energy levels.
Some researchers believe that certain UFOs absorb energy from lightning as a means of propulsion or power generation. In past cases, similar sightings have been reported in the presence of electrical storms, further fueling theories that such crafts may recharge their systems using natural energy sources.
It is known that theoretical physics explores the concept of extracting energy from electrical phenomena, such as Tesla’s ideas about wireless energy transmission. If an advanced civilization mastered this, lightning could be a viable energy source.

On March 26, 2020, a French astronomer Mark Carlotto used a telescope to capture a video showing the moon at night. Dr. M. Carlotto is a specialist in digital video analysis of space objects. The video shows three objects rising above the Moon’s limb, flying across the lunar surface and disappearing in the Moon’s shadow.
The fact that some of these objects are so clearly visible and close enough to the moon to be able to cast noticeable shadows immediately suggests that they are quite large. Using the large Endymion crater as a benchmark, the sizes of the objects were determined.
The size of the object flying over Endymion is about 5 miles long and about 1 to 3 miles wide. The other two objects appear to be comparable in size.
By measuring the displacement of the object it appears that the object is traveling at about 31 mps. It is traveling more than 30 times faster than if it were in lunar orbit.
A paper was recently published that attempts to prove that the original video is a fake. Arxiv.org analyzed the video (not included in the analysis) but extracted and provided three images of the recorded objects for examination, as seen above, and they then conducted calculations to verify its authenticity.
Despite government and space agency denials of UFO existence, photographic evidence and subsequent analysis suggest the presence of large extraterrestrial craft near the Moon and elsewhere in space.View the full article

On January 25, 2025, an Oklahoma City man recorded a baffling UFO that he described as a "plasma-filled jellybean." A concerned neighbor also spotted something unusual in the sky and soon, the entire neighborhood gathered outside, to witness the anomaly.
The mysterious object emitted a glow and moved erratically, mesmerizing onlookers. In his recorded footage, Frederick can be heard narrating the event. "I don’t hear anything, and it's moving unpredictably," he noted. "It looks like a jellybean, but the interior appears to be plasma."
Frederick decided to launch his drone for a closer look, but upon attempting to deploy his drone, he encountered unexplained technical failures. "My controller provides voice notifications," he explained. "It repeatedly announced, ‘unable to take off, electromagnetic interference."
After multiple attempts, he finally got the drone airborne, reaching approximately 1,000 feet beneath the UFO. However, just after capturing three images, the drone’s video function failed, and its battery, despite being fully charged, suddenly drained. "It had a 35-minute flight time," Frederick stated. "But right after taking those three pictures, the controller alerted me: ‘low battery, return to home."
Seeking expert insight, Frederick shared his footage and images with University of Oklahoma physics professor Mukremin Kilic. When asked about the sighting, Kilic remarked, "I don’t know what it is" and suggested the object was likely a drone. However, this theory does not explain why Frederick’s own drone experienced interference, raising further questions about the true nature of the UFO.

During a live Fox News broadcast covering the intense Palisades wildfire in California, an unusual event captured viewers' attention. A camera aimed at the blazing inferno recorded a mysterious spherical object emerging suddenly from the middle of the flames. This object moved at a remarkable speed before vanishing over the treetops, leaving many wondering about its origin and purpose.
The object does not appear to be debris carried aloft by the fire’s updraft. Its trajectory and speed seem too controlled and deliberate to be a random effect of the wildfire. Additionally, the object shows no signs of explosion or disintegration, characteristics that might be expected if it were merely a piece of material affected by the intense heat.
Observers have ruled out common explanations such as birds, planes, or helicopters. The object’s rapid movement and apparent change in direction suggest advanced maneuverability, sparking comparisons to UFOs/UAPs.
With the growing number of reported sightings involving drones, orbs, and UFOs, the appearance of this potential UFO or drone in such an environment is especially intriguing. Could this object represent evidence of advanced technology monitoring Earth's natural disasters? Or is it an entirely natural but poorly understood phenomenon?
