Unusual and Unexplainable Structures Hover Above the Earth, According to NASA Scientists

By: Alyssa Miller | Last updated: Jul 25, 2024

NASA scientists have reported sightings of mysterious shapes flying around above the Earth. The unusual sightings tend to appear out of nowhere at unforeseen times and have sparked considerable interest in their origin, with some scientists suggesting they could help us better understand the complexities of our planet’s atmosphere.

Despite the immediate temptation to suggest these unusual shapes are some form of alien craft hovering above the Earth, researchers have offered an alternative explanation. They claim the phenomena could actually help improve radio communication and researchers to better predict space weather patterns.

Studying the Atmosphere

Researchers worldwide spend considerable time studying the various layers of Earth’s atmosphere, hoping to gain a better understanding of this complex system.

During recent observations of the ionosphere high above the surface of our planet, NASA researchers observed unusual X and C shapes that appeared spontaneously in the electrified layer of gas.

Global-Scale Observations of the Limb and Disk

NASA researchers uncovered the mysterious shapes while using an instrument known as the Global-scale Observations of the Limb and Disk (GOLD), a mission led by Richard Eastes Laboratory for Atmospheric and Space Physics.

GOLD aims to image the boundary between Earth and space in an attempt to better understand the solar and atmospheric variability of our planet’s space weather.

GOLD Has Observed Similar Shapes Before

The recent observations of mysterious C- and X-shaped formations in the ionosphere are not the first time such phenomena have been witnessed. However, GOLD has provided researchers with much clearer images.

For the first time, the imaging instrument has also found these shapes in unexpected places, leading scientists to suggest we have a lot more to learn about the ionosphere and its effects on navigation and communication signals that travel through it.

What is Earth's Ionosphere?

Earth’s ionosphere is part of our planet’s upper atmosphere, sitting between 50 and 400 miles above the surface. Throughout the day, sunlight comes into contact with the field, electrically charging it in the process.

As sunlight strikes the ionosphere, electrons are knocked off atoms and molecules, creating a unique soup of particles called plasma. This plasma is the source of the unusual X and C spades witnessed by the GOLD instrument.

Could the Discovery Improve Radio Communication?

The discovery of these shapes dancing around in the ionosphere has led some researchers to suggest they could revolutionize radio communications and weather forecasting in space, potentially enhancing their effectiveness.

In previous studies, researchers determined that merging plasma led to the creation of X shapes in the wake of solar storms and enormous volcanic eruptions.

New Data on Observable Shapes in the Ionosphere

New data published in The Journal of Geophysical Research: Space Physics explained the shapes can also form in what the researchers deem “quiet times.”

This suggests that certain localized factors can also influence the appearance of shapes in the ionosphere. In their study, the researchers noted that computer models have shown that lower atmospheric conditions could potentially pull the plasma downwards.

NASA Researcher Shares Opinion Emergence of Shapes

Fazlul Laskar, an ionosphere physicist at the University of Colorado who co-authored the paper, shared a statement with NASA, explaining, “Earlier reports of merging were only during geomagnetically disturbed conditions.”

Formation of C Shapes Leaves Researchers Puzzled

Researchers have been left puzzled by the rarer C- and reverse C-shaped bubbles in the plasma of the ionosphere. Initially, they were thought to have been created by winds on Earth.

However, GOLD has captured images of these C’s forming close together, sometimes as little as 400 miles apart. Again, this suggests more localized factors are behind the creation of the mysterious shapes, with some postulating tornadoes as a source.

Rare C Shapes in the Ionosphere

While the groups of C shapes remain very sparse at the moment, researchers have revealed they will continue to investigate the phenomena, hoping to better understand what’s behind their appearance in the ionosphere.

Further Studies on the Unusual Shapes

Plasma in the ionosphere plays a pivotal role in enabling radio waves to travel long distances, so any disruption will negatively affect Earth’s communication and navigational infrastructure.

A Structure Above Jupiter’s Great Red Spot

The Earth isn’t the only planet that has unexpected structures floating above it. Scientists discovered that Jupiter’s Great Red Spot—a long-lasting area of high pressure on Jupiter that creates a persistent storm—is showing unusual activity.

Jupiter’s Upper Atmosphere

The researchers found that this variation is not sunlight, which the planet uses to create energy, but a deeper messy layer of the Jovian atmosphere.

Little is known about Jupiter’s atmosphere. Researchers know that the atmosphere is mostly hydrogen and helium, but the visible clouds are ammonia. Underneath are water clouds, but the winds below that are unchanging.

The Waves in the Atmosphere

“One way in which you can change this structure is by gravity waves—similar to waves crashing on a beach, creating ripples in the sand,” explained team leader Henrik Melin, of the University of Leicester in the United Kingdom, said in a statement.

Jupiter Has Been a Bit of a Mystery

These observations were a part of the Early Release Science program (ERS) for the James Webb Space Telescope (JWSP). More and more astronomers have become curious about what is happening in Jupiter’s upper atmosphere for a while.

More Strange Phenomena

These markings are not the only strange phenomena that lit up the Earth’s sky. While each of these observations comes with speculation about something else happening (maybe aliens or something more Lovecraftian), there is a scientific explanation behind these bizarre sightings.

Red Lights in the Sky

Above the town of Possagno in northern Italy, a disk of red light appears in the sky for a few milliseconds before abruptly vanishing. The fluorescent frisbee is known as an “emission of light and very low-frequency perturbations due to electromagnetic pulse sources,” (via LiveScience).

To put it in simple terms, lightning produces an electromagnetic pulse that hits Earth’s ionosphere, creating a halo that gives off a red color because the lightning interacts with the nitrogen atoms in the ionosphere.

Heavenly Halos

An astronomer at Queen’s University Belfast in Northern Ireland showed a spectacular set of luminous arcs and halo shining around the sun. While many dismiss these ethereal lights as a lens flare, sunlight shining through millions of tiny ice crystals actually creates them by refracting light.

When strong winds move these ice crystals around, it position them in a way that can create an optical phenomenon.

A Whirlpool of Light

Above the night sky of Alaska, an ethereal whirlpool of blue light emerged from the strong auroral display. This spiral-shaped object had nothing to do with the polar lights, but the results of frozen rocket fuel ejected by the second stage of SpaceX’s Falcon 9 rockets.

Rainbow Clouds

What is more beautiful than a purple and pink evening sky? Well, how about a rainbow one? These multicolor clouds, known as polar stratospheric clouds, were spotted in the night sky above the Arctic.
