Astronomers found that exoplanet TOI-1452 b could be a so-called water world.

The anatomy of water worlds.

Exoplanet TOI-1452 b is orbiting red dwarf TOI-1452 for 11 days. There is a possibility, that a thick water layer covers the entire exoplanet TOI-1452 b. That thing makes that exoplanet very interesting. TOI-1452 b is 70 times larger than Earth and five times more massive than our planet. TOI-1452 b is possible a locked planet where powerful winds are blowing because the difference in temperature between day and night sides is very big. So what kind of world the water world can be?

That temperature difference causes extremely strong winds. The windspeed in those jet streams can rise over Mach 1. The difference in the wind speed in latitudes causes the stripes in the water world's atmosphere and the friction between those stripes will heat the atmosphere of the water world.

And if there forms some kind of hurricanes in the atmosphere of water worlds those hurricanes can stay years. The water worlds have stripes because there is nothing that can disturb the atmosphere. Forming clouds requires islands or dry areas. Ans waves require that there is some kind of shoals.

If there are no shoals or landmass the oceans can be very slight, because nothing will cause the waves. There are possible massive vertical flows that are chancing water at the surface. But those flows require that there is some kind of volcanic activity below the ocean. There is the possibility that water layers over the water world exoplanets are even thousands of kilometers deep.

The massive gravitation can pull water even to ice. The exoplanet Gliese 461 b has a surface covered by ice even if the temperature on that planet is 436 degrees Celsius, but the extreme gravitation pulls water to ice on that planet.

There is also the possibility that a thick water layer presses the bottom of the ocean to ice. The reason for that is the extremely high pressure will deny the oscillation of water molecules.

But if the gravitation on the surface of the water world is stronger on Earth but lower than forming of hot ice requires. That means the water will not boil at 100 degrees Celsius. So the oceans of the water worlds can be extremely hot, and they will not boil. Because of massive gravitation.

There is possible that that planet's ocean swims some kind of lifeforms that are similar to that swam in Earth's oceans before the oxygen is released into the Atmosphere. The water worlds are exoplanets that can support quite similar lifeforms like fishes or sea insects even if that planet is in a powerful radiation zone. The water layer protects animals that are living in that ocean.

Can there be intelligent lifeforms on water worlds?

The ocean worlds are very interesting in the point of search for intelligent lifeforms. The intelligent lifeforms can make undersea structures and underwater stations for protecting themselves against the powerful radiation of the central star of some water world. But in most of those models, the intelligent civilization must form on other planets.

On the water worlds themselves, the endemic species cannot reach the level of the technically advanced civilization, because they cannot make fire or melt metals, which is the key element for technical inventions. But there is always the possibility that the endemic species can use volcanic temperature for melting metals, that was the first step for humans on that route to technically advanced species.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper? The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown. But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology. Could a hypothetical Planet X tunnel all radiation? The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory. And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact. In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells. Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
