Interstellar objects and exoplanet hunting.

“Interstellar object ʻOumuamua sped up as it approached the Sun, shooting past at 196,000 mph (315,431 km/h) and then slowing down as it moved away” (Astronomy, Why aren’t free-floating planets captured when they fly past stars?)

Stars could capture a rogue planet. But that is not as common as many people think. When a planet enters another solar system, it must release its kinetic energy. And rogue planets have a massive amount of kinetic energy. If. That object arrives in the solar system too steeply. its fate would be the star in the middle of the solar system. If. The angle is too shallow. That exoplanet travels straight through the solar system. 

The star could capture a rogue planet if it has the right angle and the right speed. This means that the star should travel behind the planet, following its trajectory. The gravitational brake will slow the planet’s speed. And if that planet arrives in the solar system at the precise right angle. It can start to orbit that star. Things. Like 3/Atlas and other interstellar asteroids. They follow the same rules as larger rogue planets.

In reality, we can see only large exoplanets. That. Orbit M-type red dwarfs. 

When we ask whether aliens can see Earth. If. They have similar technology. To. That we have. We can rephrase that question. Can we see an Earth-type planet that orbits its star in the habitable zone? The answer is that a G-spectral-class star is so bright. Its shine. It covers an Earth-type planet. Under its brightness. In planet hunting. Astronomers use methods that benefit from the planet's transit. When. A planet comes between Earth and its own sun. That. Affects the star’s brightness. 

If. The star is small enough. The large exoplanet can affect its trajectory. The wobbling trajectory caused suspicions that Barnard’s Star had exoplanets. Most exoplanets that we know are large. They orbit dim and light stars. And we cannot see Earth-like planets that orbit. Bright stars. The case is similar to Betelgeuse. The brightness of the center star. It covers. The. Dimmer companion under it. Betelgeuse is one of the most well-known stars in the sky. The B-type companion star was confirmed in 31.72026. 

Before astronomers can confirm the existence of the exoplanet. They. Must rule out other possibilities, like changes in the star’s own brightness. Another method astronomers can use is looking for holes in planetary nebulae around stars. Large exoplanets form holes in that nebula. But those nebulae surround only young stars. That method is not suitable for long-distance observations. Things like IR telescopes could see planets through dust and ice. The big problem is that stars also warm dust. 

The surface area of the interplanetary nebula is larger than a planet. And the IR telescopes see that dust. But that dust covers the planet under its IR glow. We can get direct images only from the closest exoplanets. And that requires that they orbit a red dwarf. The reason.  For why. We can see Planets like Proxima B. It is that. They orbit red dwarfs. Those dim stars are dim enough that sensors can measure changes in their brightness. The fact is that. We can’t see a planet that orbits Alpha Centauri or a brighter star. When. A star shines through the exoplanet's atmosphere. That. Allows astronomers. to. make a spectral analysis of the planet’s atmosphere and its chemical fingerprint. This works only with dim stars. That don’t outshine those exoplanets with their brightness.

Pentagon cannot explain over half of 2022 UAPs or "UFO evidence".

The new UFO or UAP (Unknown Aerial Phenomena) report introduces 170 cases that Pentagon cannot explain. This is the new way to study the UAPs or UFOs. Being open and following the scientific and empirical methodology makes much more positive things than just telling the stories about "weather balloons" or some schizophrenia cases. 

The UAPs:s and the UFOs are the same phenomena. Those cases involve strange weather objects, flying unknown objects, and other airborne things, but remain a mystery. Of course, many of those cases are air trash or spy drones. But some of those cases remain a mystery. 

The thing that connects real  UFO incidents is their origins are a mystery. There is a flying thing that has no owner. There are many theories about aliens and other kinds of things. And researchers must keep their minds open when they are trying to research that thing. But nobody confesses being behind those UFOs:s. 

In media is told that UFOs are real, but their origin is unknown. And when we are thinking about China or Russia as the origin of those mystery cases, we must ask a simple question: is the technology in those countries so high-level that they could produce the UFO? 

The second image is the phenomenon where the rising smoke forms a tornado. There is low pressure in that tornado. 

And it pulls clouds down. And that forms the object that looks like a "saucer". If that rising air tornado would stronger than it's now. That thing would form thrombi. But that kinds of weather objects are easy to explain.

The unknown things like small-size saucer-shaped crafts are unknown. Those crafts that behave in a very interesting way might be some kind of drone. That explains why those systems can make sudden changes in their courses. But who is behind those things? 

The fact is that there were lots of misunderstandings in the past. The UFO research stamped to work of maniacs. And some people even laughed at those investigators who tried to find out the truth behind those mystery objects. When we are thinking about the possibility that the U.S. air force has captured the UFO and transferred it to AREA-51, there is always the possibility that the story is true. 

One of the reasons why the government kept UFO cases secret was probably that those unknown objects were used as models for new fundamental aviation systems. The thing is that UFOs are real, but the origin of those systems is unknown. Keeping those cases secret doesn't serve anybody. 

The thing is that we must find the thing that is behind those very interesting cases. Some researchers believe that aliens might visit Earth. That thing is one of the possibilities that we must keep open. Or we must not close any possibilities away without careful research.
