Many unusual phenomena are witnessed in the sky, ranging from UFOs and mysterious orbs to figures from parallel universes. One notable incident occurred during a recent thunderstorm from an unknown location when amidst the raging storm, a powerful flash of lightning illuminates the night sky, revealing the haunting silhouette of a demon, caught mid-air.
While this eerie vision was likely a result of the lightning itself, some claim it resembled Raijin, the Shinto god of lightning and thunder, a chaotic being born of death who brings the world vital rains as well as chaos and destruction .
Regardless of the true nature of this event, it serves as a reminder that countless mysterious phenomena exist on and around our planet. Whether tied to the afterlife, parallel universes, intelligent extraterrestrial life, or folklore with roots in truth, most of these occurrences remain unexplained.

Rubio broke the record of longest single duration spaceflight for a U.S. astronaut with a mission duration of 371 days; Berrios graduated in the most recent class of astronaut candidates.
Hispanic Heritage Month commemorates and honors the rich history of the shared culture and tradition of American citizens whose ancestors came from Spain, Mexico, the Caribbean, and Central and South America. Read some of their stories.

NASA Develops Process to Create Very Accurate Eclipse Maps
New NASA research reveals a process to generate extremely accurate eclipse maps, which plot the predicted path of the Moon’s shadow as it crosses the face of Earth. Traditionally, eclipse calculations assume that all observers are at sea level on Earth and that the Moon is a smooth sphere that is perfectly symmetrical around its center of mass. As such, these calculations do not take into account different elevations on Earth or the Moon’s cratered, uneven surface.
For slightly more accurate maps, people can employ elevation tables and plots of the lunar limb — the edge of the visible surface of the Moon as seen from Earth. However, now eclipse calculations have gained even greater accuracy by incorporating lunar topography data from NASA’s LRO (Lunar Reconnaissance Orbiter) observations.
Using LRO elevation maps, NASA visualizer Ernie Wright at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, created a continuously varying lunar limb profile as the Moon’s shadow passes over the Earth. The mountains and valleys along the edge of the Moon’s disk affect the timing and duration of totality by several seconds. Wright also used several NASA data sets to provide an elevation map of Earth so that eclipse observer locations were depicted at their true altitude.
The resulting visualizations show something never seen before: the true, time-varying shape of the Moon’s shadow, with the effects of both an accurate lunar limb and the Earth’s terrain.
“Beginning with the 2017 total solar eclipse, we’ve been publishing maps and movies of eclipses that show the true shape of the Moon’s central shadow — the umbra,” said Wright.

NASA SVS/Ernie Wright and Michaela Garrison “And people ask, why does it look like a potato instead of a smooth oval? The short answer is that the Moon isn’t a perfectly smooth sphere.”
The mountains and valleys around the edge of the Moon change the shape of the shadow. The valleys are also responsible for Baily’s beads and the diamond ring, the last bits of the Sun visible just before and the first just after totality.

NASA SVS/Ernie Wright Wright is lead author of a paper published September 19 in The Astronomical Journal that reveals for the first time exactly how the Moon’s terrain creates the umbra shape. The valleys on the edge of the Moon act like pinholes projecting images of the Sun onto the Earth’s surface.

Light rays from the Sun converge on each valley, then spread out again on their way to the Earth. NASA SVS/Ernie Wright The umbra is the small hole in the middle of these projected Sun images, the place where none of the Sun images reach.
Viewed from behind the Moon, the Sun images projected by lunar valleys on the Moon’s edge fall on the Earth’s surface in a flower-like pattern with a hole in the middle, forming the umbra shape. NASA SVS/Ernie Wright The edges of the umbra are made up of small arcs from the edges of the projected Sun images.
This is just one of several surprising results that have emerged from the new eclipse mapping method described in the paper. Unlike the traditional method invented 200 years ago, the new way renders eclipse maps one pixel at a time, the same way 3D animation software creates images. It’s also similar to the way other complex phenomena, like weather, are modeled in the computer by breaking the problem into millions of tiny pieces, something computers are really good at, and something that was inconceivable 200 years ago.

Reports of alien abductions first became widespread during the 1960s and 70s. Alleged abductees frequently described undergoing experimental procedures performed by extraterrestrial beings. Some even claimed that these aliens had inserted unknown objects into their bodies.
In many cases, these so-called "alien implants" are metallic and have been reported to emit radio frequency waves. Often, they are found attached to nerve endings within the body.
One of the most prominent figures in this field of research was Dr. Roger Leir, who passed away on March 14, 2014. Along with his surgical team, Dr. Leir performed 17 surgeries on individuals who claimed to have been abducted by aliens, removing 13 distinct objects suspected to be alien implants.
These objects were subjected to scientific analysis by prestigious laboratories, including Los Alamos National Labs, New Mexico Tech, and the University of California at San Diego. The findings have been puzzling, with some comparisons made to meteorite samples, and isotopic ratios in some tests suggesting materials not of Earthly origin.
One such case is that of Terry Lovelace, a former Air Force medic, who kept a disturbing secret for 40 years. In 2012, a routine x-ray revealed a small square object about the size of a fingernail which was buried deep in Terry's right leg the doctor had never see anything like it.
Then Terry suddenly remembered the terrifying experience he had tried to forget - an event during a camping trip at Devil's Den State Park that he had never spoken of, knowing no one would believe him without proof. Yet the evidence had always been there: a strange metal object embedded in his leg, something that was not man-made.
In 1977, Terry and a friend had an extraordinary encounter at Devil's Den State Park, where they witnessed a massive triangular craft. This experience resulted in missing time and unexplained injuries. Years later, Terry was faced with a difficult choice: reveal his story of alien contact or remain silent. His decision led him into conflict with powerful forces and uncovered a conspiracy that extended beyond our world.
While some remain skeptical, believing these implants are man-made and part of a secretive human agenda, Dr. Leir’s work, along with Terry Lovelace's experience at Devil’s Den and the mysterious object found in his leg, suggests that 'alien' implants may not be mere fiction.
