A strange image has been circulating across social media in Thailand, showing a large, dark pillar-like structure mysteriously appearing in the sky over Ubon Ratchathani. According to the photographer, the picture was taken on Sunday, October 20, 2024, while they were trying to capture the "beautiful, colorful sky.
This peculiar sighting isn't entirely unprecedented. Similar strange phenomena have been reported before. On October 7, 2015, a mysterious "floating city" with skyscrapers appeared in the clouds over Foshan, Guangdong province in China. Again, on March 18, 2016, ghostly buildings were seen above the sea along the port of Dalian, in Liaoning Province, China, lingering in the sky for several minutes.
Most recently, on September 11, 2020, an eerie image resembling the Hogwarts School from Harry Potter was spotted hovering over modern buildings in Jinan, Shandong Province. On July 14, 2022, a bizarre occurrence was also witnessed by residents in Haikou, Hainan, where a mysterious floating city appeared in the sky.
Scientists suggest that these events are most likely optical illusions, with mirages being the leading theory. Mirages occur when light rays bend, causing distant objects or parts of the sky to appear displaced. One specific type, known as a Fata Morgana, can create towering, distorted images of distant objects, contributing to these surreal sights.
Although the sightings between 2015 and 2022 were witnessed by many, the photographer in Thailand later realized that the mysterious pillar hadn't been visible to the naked eye at the time. This discovery has led some to speculate that the phenomenon might have been caused by a Project Blue Beam test, holographic technology, or even a temporary vortex connected to a parallel universe.

NASA, ESA/Matthias Maurer An astronaut aboard the International Space Station snapped this picture of the Moon as the station orbited 265 miles above the U.S. state of Minnesota on Dec. 17, 2021.
Astronauts aboard the orbital lab take images using handheld digital cameras, usually through windows in the station’s cupola, for Crew Earth Observations. Crew members have produced hundreds of thousands of images of the Moon and Earth’s land, oceans, and atmosphere.
On Saturday, Sept. 14, 2024, International Observe the Moon Night, everyone on Earth is invited to learn about lunar science, participate in celestial observations, and honor cultural and personal connection to the Moon. Find an event to join in the celebration.

Hubble Traces Star Formation in a Nearby Nebula
NASA, ESA, and L. C. Johnson (Northwestern University); Image Processing: Gladys Kober (NASA/Catholic University of America) NGC 261 blooms a brilliant ruby red against a myriad of stars in this new image from NASA’s Hubble Space Telescope. Discovered on Sept. 5, 1826 by Scottish astronomer James Dunlop, this nebula is located in one of the Milky Way’s closest galactic companions, the Small Magellanic Cloud (SMC). The ionized gas blazing from within this diffuse region marks NGC 261 as an emission nebula. It is home to numerous stars hot enough to irradiate surrounding hydrogen gas, causing the cloud to emit a pinkish-red glow.
This inset image shows the location of NGC 261 within the Small Magellanic Cloud. NASA, ESA, L. C. Johnson (Northwestern University), and ESO/VISTA VMC; Image Processing: Gladys Kober (NASA/Catholic University of America) Hubble turned its keen eye toward NGC 261 to investigate how efficiently stars form in molecular clouds, which are extremely dense and compact regions of gas and dust. These clouds often consist of large amounts of molecular hydrogen — cold areas where most stars form. However, measuring this raw fuel of star formation in stellar nurseries is a challenge because molecular hydrogen doesn’t radiate easily. Since it is difficult to detect, scientists instead trace other molecules present in the molecular clouds.
The SMC hosts a gas-rich environment of young stars along with trace amounts of carbon monoxide (CO), a chemical correlated with hydrogen and often used to identify the presence of such clouds. Using the Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3), Hubble imaged these stars in the southwest portion of the SMC where NGC 261 resides. The combined power of ACS and WFC3 allowed scientists to closely examine the nebula’s star-forming properties through its CO content at optical and near-infrared wavelengths. This research helps astronomers better understand how stars form in our home galaxy and others in our galactic neighborhood.

On 8 September 2024, the first of four satellites that make up ESA’s Cluster mission will reenter Earth’s atmosphere over the South Pacific Ocean Uninhabited Area.
This marks the end of the historic mission, over 24 years after it was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come.
This ‘targeted reentry’ is the first of its kind. ESA’s efforts to ensure a clean end to the Cluster mission go beyond international standards, making the agency a world-leader in sustainable space exploration.
