NASA’s 1991 Discovery shuttle video shows UFOs making impossible maneuvers, evading a possible Star Wars railgun test. Evidence of secret tech?
In September 1991, NASA’s Space Shuttle Discovery transmitted live video that has since become one of the most debated UFO clips ever recorded. The footage, later analyzed by independent researchers, shows glowing objects in orbit performing maneuvers far beyond the limits of known physics.
One object appears over Earth’s horizon, drifts smoothly, then suddenly reacts to a flash of light by accelerating at impossible speeds, estimated at over 200,000 mph while withstanding forces of 14,000 g’s. NASA officially dismissed the anomalies as ice particles or debris, but side by side comparisons with actual orbital ice show key differences: the objects make sharp turns, sudden accelerations, and fade in brightness in ways consistent with being hundreds of miles away, not near the shuttle.
Image analysis expert Dr. Mark Carlotto confirmed that at least one object was located about 1,700 miles from the shuttle, placing it in Earth’s atmosphere. At that distance, the object would be too large and too fast to be dismissed as ice or space junk.
The flash and two streaks seen in the video resemble the Pentagon’s “Brilliant Pebbles” concept, a railgun based missile defense system tested in the early 1990s. Researchers suggest the shuttle cameras may have accidentally, or deliberately, captured a live Star Wars weapons test in orbit.
The UFO easily evaded the attack, leading some to conclude that it was powered by a form of hyperdimensional technology capable of altering gravity.
Notably, following this 1991 incident, all subsequent NASA shuttle external camera feeds were censored or delayed, raising speculation that someone inside the agency allowed the extraordinary footage to slip out.

Hubble Examines Low Brightness, High Interest Galaxy
This NASA/ESA Hubble Space Telescope image features a portion of the spiral galaxy NGC 45. ESA/Hubble & NASA, D. Calzetti, R. Chandar; Acknowledgment: M. H. Özsaraç This NASA/ESA Hubble Space Telescope image zooms in on the feathery spiral arms of the galaxy NGC 45, which lies just 22 million light-years away in the constellation Cetus (the Whale).
The portrait uses data drawn from two complementary observing programs. The first took a broad view of 50 nearby galaxies, leveraging Hubble’s ability to observe ultraviolet through visible into near-infrared light to study star formation in these galaxies. The second program examined many of the same nearby galaxies as the first, narrowing in on a particular wavelength of red light called H-alpha. Star-forming nebulae are powerful producers of H-alpha light, and several of these regions are visible across NGC 45 as bright pink-red patches.
These observing programs aimed to study star formation in galaxies of different sizes, structures, and degrees of isolation — and NGC 45 is a particularly interesting target. Though it may appear to be a regular spiral galaxy, NGC 45 is a remarkable type called a low surface brightness galaxy.
Low surface brightness galaxies are fainter than the night sky itself, making them incredibly difficult to detect. They appear unexpectedly faint because they have relatively few stars for the volume of gas and dark matter they carry. In the decades since astronomers serendipitously discovered the first low surface brightness galaxy in 1986, researchers have learned that 30–60% of all galaxies may fall into this category. Studying these hard-to-detect galaxies is key to understanding how galaxies form and evolve, and Hubble’s sensitive instruments are equal to the task.

This photo was taken by astronauts aboard the International Space Station during Expedition 44. Credit: NASA astronauts on board Expedition 44 Did you see that gorgeous photo NASA astronaut Nichole Ayers took on July 3, 2025? Originally thought to be a sprite, Ayers confirmed catching an even rarer form of a Transient Luminous Events (TLEs) — a gigantic jet.
“Nichole Ayers caught a rare and spectacular form of a TLE from the International Space Station — a gigantic jet,” said Dr. Burcu Kosar, Principal Investigator of the Spritacular project.
Gigantic jets are a powerful type of electrical discharge that extends from the top of a thunderstorm into the upper atmosphere. They are typically observed by chance — often spotted by airline passengers or captured unintentionally by ground-based cameras aimed at other phenomena. Gigantic jets appear when the turbulent conditions at towering thunderstorm tops allow for lightning to escape the thunderstorm, propagating upwards toward space. They create an electrical bridge between the tops of the clouds (~20 km) and the upper atmosphere (~100 km), depositing a significant amount of electrical charge.
Sprites, on the other hand, are one of the most commonly observed types of TLEs — brief, colorful flashes of light that occur high above thunderstorms in the mesosphere, around 50 miles (80 kilometers) above Earth’s surface. Unlike gigantic jets, which burst upward directly from thundercloud tops, sprites form independently, much higher in the atmosphere, following powerful lightning strikes. They usually appear as a reddish glow with intricate shapes resembling jellyfish, columns, or carrots and can span tens of kilometers across. Sprites may also be accompanied or preceded by other TLEs, such as Halos and ELVEs (Emissions of Light and Very Low Frequency perturbations due to Electromagnetic Pulse Sources), making them part of a larger and visually spectacular suite of high-altitude electrical activity. The world of Transient Luminous Events is a hidden zoo of atmospheric activity playing out above the storms. Have you captured an image of a jet, sprite, or other type of TLE?

ESA’s Hera mission has captured images of asteroids (1126) Otero and (18805) Kellyday. Though distant and faint, the early observations serve as both a successful instrument test and a demonstration of agile spacecraft operations that could prove useful for planetary defence.
Hera is currently travelling through space on its way to a binary asteroid system. In 2022, NASA’s DART spacecraft impacted the asteroid Dimorphos, changing its orbit around the larger asteroid Didymos. Now, Hera is returning to the system to help turn asteroid deflection into a reliable technique for planetary defence.
