While observing the Orion Nebula with his 12-inch Dobsonian telescope, a sky-watcher noticed an unusual flashing object. As stars appeared to drift due to Earth's rotation, this particular object while flashing approximately every 20 seconds clearly travels through deep space.
The observer wonders whether it might be a rotating satellite or not. However, this isn’t the first sighting of cigar-shaped UFOs or other mysterious objects traveling through space near the Orion Nebula, so it is quite possible that it could be an interstellar craft.
Over the years, I have shared several articles, complete with images and videos, documenting similar UFO sightings around the Orion Nebula. You can explore these under the tag: Orion Nebula.
Interestingly, these sightings have all occurred between November and February, suggesting there may be a seasonal pattern to these observations.

This diagram compares the size of the icy, solid nucleus of comet C/2014 UN271 (Bernardinelli-Bernstein) to several other comets. The majority of comet nuclei observed are smaller than Halley’s comet. They are typically a mile across or less. Comet C/2014 UN271 is currently the record-holder for big comets. And, it may be just the tip of the iceberg. There could be many more monsters out there for astronomers to identify as sky surveys improve in sensitivity. Though astronomers know this comet must be big to be detected so far out to a distance of over 2 billion miles from Earth, only the Hubble Space Telescope has the sharpness and sensitivity to make a definitive estimate of nucleus size.

If you spotted comet C/2023 A3 (Tsuchinshan-ATLAS) in person, or seen photos online this October, you might have been inspired to learn more about these visitors from the outer Solar System. Get ready for the next comet and find out how comets are connected to some of our favorite annual astronomy events.
Comet Composition
A comet is defined as an icy body that is small in size and can develop a ‘tail’ of gas as it approaches the Sun from the outer Solar System. The key traits of a comet are its nucleus, coma, and tail.
The nucleus of the comet is comprised of ice, gas, dust, and rock. This central structure can be up to 80 miles wide in some instances, as recorded by the Hubble Space Telescope in 2022 – large for a comet but too small to see with a telescope. As the comet reaches the inner Solar System, the ice from the nucleus starts to vaporize, converting into gas. The gas cloud that forms around the comet as it approaches the Sun is called the coma. This helps give the comet its glow. But beware: much like Icarus, sometimes these bodies don’t survive their journey around the Sun and can fall apart the closer it gets.
The most prominent feature is the tail of the comet. Under moderately dark skies, the brightest comets show a dust tail, pointed away from the Sun. When photographing comets, you can sometimes resolve the second tail, made of ionized gases that have been electronically charged by solar radiation. These ion tails can appear bluish, in comparison to the white color of the dust tail. The ion tail is also always pointed away from the Sun. In 2007, NASA’s STEREO mission captured images of C/2006 P1 McNaught and its dust tail, stretching over 100 million miles. Studies of those images revealed that solar wind influenced both the ion and dust tail, creating striations – bands – giving both tails a feather appearance in the night sky.

Comets appear from beyond Uranus, in the Kuiper Belt, and may even come from as far as the Oort Cloud. These visitors can be short-period comets like Halley’s Comet, returning every 76 years. This may seem long to us, but long-period comets like Comet Hale-Bopp, observed from 1996-1997 won’t return to the inner Solar System until the year 4385. Other types include non-periodic comets like NEOWISE, which only pass through our Solar System once.
But our experiences of these comets are not limited to the occasional fluffy snowball. As comets orbit the Sun, they can leave a trail of rocky debris in its orbital path. When Earth finds itself passing through one of these debris fields, we experience meteor showers! The most well-known of these is the Perseid meteor shower, caused by Comet 109P/Swift-Tuttle. While this meteor shower happens every August in the northern hemisphere, we won’t see Comet Swift-Tuttle again until the year 2126.

Over the years, numerous mysterious events have been witnessed in the sky, defying explanation. Recently, yet another unusual sky phenomenon was observed over Southern Australia capturing attention and sparking curiosity.
Video footage reveals what appears to be a dome-shaped structure, with an even stranger detail: lightning seems to bounce off or perhaps even originate from within the dome.
The mysterious formation has led to numerous theories. Some viewers suggest it could be a unique (red) rainbow or a rare weather event like a haboob (sandstorm). Others speculate it might be the result of weather manipulation or even an energy field projected over the region.
Opinions also vary on the lightning, some say it’s bouncing off the dome, while others believe it could be emanating from within. Although it may just be an unusual natural phenomenon, the seemly strange interaction with the lightning remains unexplained.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Francisco Rodriguez (aircraft mechanic) services liquid oxygen or LOX on the ER-2 during the Geological Earth Mapping Experiment (GEMx) research project. Experts like Rodriguez sustain a high standard of safety on airborne science aircraft like the ER-2 and science missions like GEMx. The ER-2 is based out of NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Steve Freeman Operating at altitudes above 99% of the Earth’s atmosphere, NASA’s ER-2 aircraft is the agency’s highest-flying airborne science platform. With its unique ability to observe from as high as 65,000 feet, the ER-2 aircraft is often a platform for Earth science that facilitates new and crucial information about our planet, especially when the plane is part of collaborative and multidisciplinary projects.
“We’re deploying instruments and people everywhere from dry lakebeds in the desert to coastal oceans and from the stratosphere to marine layer clouds just above the surface,” said Kirk Knobelspiesse, an atmospheric scientist at NASA’s Goddard Space Flight Center. “We live on a changing planet, and it is through collaborative projects that we can observe and understand those changes.”
One mission that recently benefitted from the ER-2’s unique capabilities is the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) project. The PACE-PAX mission uses the ER-2’s capabilities to confirm data collected from the PACE satellite, which launched in February 2024.
The PACE observatory is making novel measurements of the ocean, atmosphere, and land surfaces, noted Knobelspiesse, the mission scientist for PACE-PAX. This mission is all about checking the accuracy of those new satellite measurements.
Sam Habbal (quality inspector), Darick Alvarez (aircraft mechanic), and Juan Alvarez (crew chief) work on the network “canoe” on top of the ER-2 aircraft, which provides network communication with the pilot onboard. Experts like these sustain a high standard of safety while outfitting instruments onboard science aircraft like the ER-2 and science missions like the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) mission. The ER-2 is based out of NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Genaro Vavuris “The ER-2 is the ideal platform for PACE-PAX because it’s about the closest we can get to putting instruments in orbit without actually doing so,” Knobelspiesse said.
The collaborative project includes a diverse team of researchers from across NASA, plus the National Oceanic and Atmospheric Administration (NOAA), the Netherlands Institute for Space Research (SRON), the University of Maryland, Baltimore County, the Naval Postgraduate School, and other institutions.
Similarly, the Geological Earth Mapping eXperiment (GEMx) science mission is using the ER-2 over multiple years to collect observations of critical mineral resources across the Western United States.
“Flying at this altitude means the GEMx mission can acquire wide swaths of data with every overflight,” said Kevin Reath, NASA’s associate project manager for the GEMx mission, a collaboration between the United States Geological Survey (USGS) and NASA.
The ER-2 conducted over 80 flight hours in service of the Plankton, Aerosol, Cloud, ocean Ecosystem Postlaunch Airborne eXperiment (PACE-PAX) mission. The ER-2 is uniquely qualified to conduct the high-altitude scientific flights that this project required, and is based at NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Genaro Vavuris The GEMx team collects visible, shortwave infrared, and thermal infrared data using instruments installed onboard the ER-2. Combining these instruments with the aircraft’s capability to fly at high altitudes bears promising results.
“The dataset being produced is the largest airborne surface mineralogy dataset captured in a single NASA campaign,” Reath said. “These data could help inform federal, tribal, state, and community leaders to make decisions that protect or develop our environment.”

NASA’s SpaceX Crew-8 members, from left to right, Roscosmos cosmonaut Alexander Grebenkin and NASA astronauts Michael Barratt, Matthew Dominick, and Jeanette Epps, are seen inside the Dragon spacecraft shortly after having landed off the coast of Pensacola, Florida, on Oct. 25, 2024. Credit: NASA/Joel Kowsky NASA’s SpaceX Crew-8 mission successfully splashed down at 3:29 a.m. EDT Friday, off Pensacola, Florida, concluding a nearly eight-month science mission and the agency’s eighth commercial crew rotation mission to the International Space Station.
After launching March 3 on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center in Florida, NASA astronauts Matthew Dominick, Michael Barratt, and Jeanette Epps, as well as Roscosmos cosmonaut Alexander Grebenkin, spent 232 days aboard the space station.
Recovery teams from NASA and SpaceX quickly secured the spacecraft and assisted the astronauts during exit. The crew now will head to NASA’s Johnson Space Center in Houston, while the Dragon spacecraft will return to SpaceX facilities at Cape Canaveral Space Force Station in Florida for inspection and refurbishment for future missions.
During their mission, crew members traveled nearly 100 million miles and completed 3,760 orbits around Earth. They conducted new scientific research to advance human exploration beyond low Earth orbit and benefit human life on Earth. Research and technology demonstrations included conducting stem cell research to develop organoid models for studying degenerative diseases, exploring how fuel temperature affects material flammability, and studying how spaceflight affects immune function in astronauts. Their work aims to improve astronaut health during long-duration spaceflights, contributing to critical advancements in space medicine and benefitting humanity.
Crew-8’s return follows the arrival of NASA’s SpaceX Crew-9 to the orbiting laboratory Sept. 29. These missions are part of NASA’s Commercial Crew Program, which provides reliable access to space, maximizing the use of the station for research and development and supporting future missions beyond low Earth orbit by partnering with private companies to transport astronauts to and from the space station.
