The Colares UFO incidents refer to a series of unusual sightings and encounters that took place in 1977 on the Brazilian island of Colares. During this period, numerous residents from the Amazon River community of Colares reported being attacked by UFOs.
These mysterious objects allegedly descended from the sky, and in some cases, emerged from the water, emitting intense beams of light. The beams caused physical harm, including burn marks, puncture wounds, fatigue, and memory loss, affecting as many as 2,000 people.
In response to the alarming situation, the Brazilian Air Force initiated a thorough investigation. Years later, their findings were made public, revealing details of this bizarre chapter in UFO history.
Weaponized hosts Jeremy and George speak with Thiago Ticchetti, Brazil's leading UFO investigator and author, to discuss the Colares case and the once-classified military files.
According to Thiago, the Brazilian military captured remarkably clear film footage and photographs of the UFOs. However, he claims that this evidence was sent to the U.S. and has never been released to the public.
In this episode, they also explores various conspiracy theories and recent debunking efforts surrounding the topic of unidentified aerial phenomena (UAP).
The discussion on the Colares UFO incidents begins at the 37-minute mark in the video.

May 2024 was a very active month for severe weather across the United States, with several hundred tornadoes occurring throughout the United States. The MSFC Disasters team has been working with several National Weather Service (NWS) Offices across the Southeast this spring to help support their damage surveys with high-resolution commercial imagery and derived products. The imagery and products are created using data provided by NASA’s Commercial Smallsat Data Acquisition (CSDA) Program. The MSFC Disasters Team’s support and expertise are providing another tool for forecasters to use when trying to understand the impacts of severe weather on their forecast area. The MSFC Disasters Team has supported the following NWS offices this spring: New Orleans/Slidell, LA, Little Rock, AR, Mobile, AL, and Huntsville, AL. Forecasters have reported back numerous examples of the imagery and products helping to confirm additional tornado tracks, and helping to modifying tracks, especially in hard-to-reach areas, such as dense forests or bayous.

Launched in December 2013, ESA’s Gaia spacecraft is on a mission to map the locations and motions of more than a billion stars in the Milky Way with extreme precision.
But it’s not easy being a satellite: space is a dangerous place. In recent months, hyper-velocity space dust and the strongest solar storm in 20 years have threatened Gaia’s ability to carry out the precise measurements for which it is famous.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This image shows SWOT satellite data for water surface height in part of Mendocino County, Northern California, on Jan. 15, before several atmospheric rivers arrived, and on Feb. 4, after the first storms. Light blue and green indicate the highest water levels relative to mean sea level. (Inland water heights include the underlying ground elevation.)NASA/JPL-Caltech Operated by NASA and the French space agency, the Surface Water and Ocean Topography mission provides a new view of water on land, at the coast, and in the ocean.
A series of atmospheric rivers drenched California in February, with record amounts of rainfall and hurricane-force winds sweeping across parts of the state. At one point, weather agencies posted flood watches for nearly the entirety of California’s coast. The Surface Water and Ocean Topography (SWOT) mission captured data on some of the flooding near the community of Manchester, roughly 105 miles (169 kilometers) north of San Francisco. The satellite is a collaboration between NASA and the French space agency, CNES (Centre National d’Études Spatiales).
The image above shows the area on Jan. 15, before the rain and snow from atmospheric rivers, and then again on Feb. 4, after the first in a series of storms soaked California. Water heights are shown in shades of green and blue, with lighter hues indicating the highest levels relative to mean sea level. (Data for inland areas includes the height of the floodwaters plus the ground elevation beneath it.) Some coastal areas were flooded by both ocean tides and heavy rain, while others were likely flooded only by precipitation. Each pixel in the image represents an area that is 330 feet by 330 feet (100 meters by 100 meters).
Since December 2022, SWOT has been measuring the height of nearly all water on Earth’s surface, developing one of the most detailed, comprehensive views yet of the planet’s oceans and freshwater lakes and rivers. Not only can the satellite detect the extent of the water on Earth’s surface, as other satellites can, but SWOT can also provide water level data. Combined with other types of information, SWOT measurements can yield water depth data in features like lakes and rivers.
“SWOT gives us information about flooding that we’ve never had before,” said Ben Hamlington, lead researcher for NASA’s sea level change team at the agency’s Jet Propulsion Laboratory in Southern California. Satellites can provide pictures showing how much of an area is flooded, but unless instruments are already installed on a river or at the coast, it’s difficult to know how conditions evolve during and after a flood. “Data from the SWOT satellite, combined with other information, is filling in this picture,” said Hamlington.
The SWOT science team made the measurements using the Ka-band Radar Interferometer (KaRIn) instrument. With two antennas spread 33 feet (10 meters) apart on a boom, KaRIn produces a pair of data swaths as it circles the globe, bouncing radar pulses off water surfaces to collect surface-height measurements.
More About the Mission
Launched in December 2022, from Vandenberg Space Force Base in central California, SWOT is now in its operations phase, collecting data that will be used for research and other purposes.
SWOT was jointly developed by NASA and CNES, with contributions from the Canadian Space Agency (CSA) and the UK Space Agency. NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California, leads the U.S. component of the project. For the flight system payload, NASA provided the KaRIn instrument, a GPS science receiver, a laser retroreflector, a two-beam microwave radiometer, and NASA instrument operations. CNES provided the Doppler Orbitography and Radioposition Integrated by Satellite (DORIS) system, the dual frequency Poseidon altimeter (developed by Thales Alenia Space), the KaRIn radio-frequency subsystem (together with Thales Alenia Space and with support from the UK Space Agency), the satellite platform, and ground operations. CSA provided the KaRIn high-power transmitter assembly. NASA provided the launch vehicle and the agency’s Launch Services Program, based at Kennedy Space Center, managed the associated launch services.

Scientists at the University of Alaska Fairbanks (UAF) and NASA want to examine the 2010 XC15 space rock to test their preparation against Apophis. This dangerous asteroid might hit our planet in 2029. It is believed that on April 13, 2029, Apophis will be 10 times closer to Earth than the moon.
The researchers will use the HAARP (High-frequency Active Auroral Research Program) array to shoot 9.6 megahertz radio waves at the 500-foot-wide 2010 XC15 asteroid.
HAARP is a government-funded research program that generally studies the ionosphere (part of Earth’s atmosphere at 50 to 400 miles above the surface). However, this will be the first time it will be employed to examine an asteroid.
Astronomers have been shooting radio waves in space to spot asteroids; figure out their shape, trajectory, structure of their surface, and many other characteristics. For this purpose, they use radio waves having frequency ranges either in the S-band (2,000 to 4,000 MHz) or X-band (8,000 to 12,000 MHz).
Interestingly, for probing 2010 XC15, the researchers are using waves of much lower frequency (9.6 MHz) and longer wavelengths because, this time, they don’t just want to explore the surface of the asteroid. They want to know what’s inside.
Information about the interiors could reveal important details about the damage that an asteroid could cause and help scientists figure out an effective counter-strategy.
Flashback: On December 27, the distance between 2010 XC15 and Earth will be around twice the distance between Earth and the moon. HAARP will be shooting 9.6 million chirping radio waves every second to this distance, and this process will be repeated every two seconds. This test is crucial because if the researchers can successfully examine 2010 XC15 using low-frequency radio waves at such a long distance. Then they could easily employ the same method to analyze Apophis.
Although the 2029 asteroid is most likely to miss Earth, in case it doesn’t, the consequences could be catastrophic.
For instance, in response to an FAQ that explores the possibility of Apophis hitting Earth, The Planetary Society wrote on its website, “Apophis would cause widespread destruction up to several hundred kilometers from its impact site. The energy released would be equal to more than 1,000 megatons of TNT, or tens to hundreds of nuclear weapons.”
Moreover, Apophis is just one asteroid. There will be many asteroids that will pass by, or might even hit, Earth in the future. Low-frequency radio waves could play a key role in understanding the composition of these mysterious space objects and, at the same time, help us strengthen our planetary defense mechanism.
However, before all this happens, HAARP and its low-frequency radio waves will have to pass their first test, which indeed has been carried out on December 27.
If the experiment worked, the pulses also reached asteroid 2010 XC15, which passed by Earth on Dec. 27th at a distance of 770,000 km. Researchers from NASA and the University of Alaska pinged 2010 XC15 with shortwave radio signals to probe the asteroid's interior--a first if it worked. They are still waiting for confirmation that the reflections were received, as expected, by antenna arrays in California and New Mexico.
They say that the 2029 Asteroid Apophis is most likely to miss Earth, but the fact that they perform this first test indicates that they are not 100 percent sure whether it will hit the Earth or not.
Also interesting is that they want to know what's inside asteroids, such as Apophis, but what will happen if they discover that the inside of an asteroid is made up of advanced technology, a hollow spacecraft built by aliens and disguised as an asteroid, like the infamous space rock ‘Oumuamua’.
