Astronomers found a one-kind-of of the triple star system.



"Artist’s interpretation of HD 98800, a quadruple-star system located 150 light-years away in the constellation TW Hydrae. Bin Liu and Alejandro Vigna-Gomez suggest that the more massive tertiary-star system"

"TIC 470710327 could have started in a similar configuration – two binary systems with one of them eventually merging into one, bigger star. TIC 470710327 is located very close to “Cassiopeia”. Credit: NASA/JPL-Caltech/UCLA" (ScitechDaily.com/“One of a Kind” Massive Triple Star System Detected)


The massive triple-star system TIC 470710327 is very special. The reason for that is those stars are extremely massive. The binary stars have a combined mass of 12 times the Sun. But the third component has the mass of 16 suns. 

The binary stars are orbiting each other very close. And because the third component is heavier than binary stars, that means the system is not yet stable. The binary stars might turn to orbit the third component. 

Because the third component is larger. That means the TIC 470710327 is not been a triple-star system very long time. Maybe the origin of this system is in the quadruple star. In that case, another pair of those star pairs have melted together.  

Or maybe, the binary star pair has impacted to heavier star's gravitational field. That explains why the heavier component is still orbiting the binary star. 

The star system is made up of a binary set of stars, two stars that orbit each other, and one more massive star that orbits the binary. There are many similar star systems in the universe. 

But the TIC 470710327 contains very heavy stars. And that makes it unique. Another thing that makes TIC 470710327 unique is that its third component is heavier than binary components. 

This kind of stellar system is interesting even if they have probably no exoplanets. But there is always the possibility that there are some cold exoplanets outside that system. Or those exoplanets can also orbit between those stars. In that case, those planets might be burning hell. There would be no lifeforms on those planets. But they might be very interesting. 

Even if planets cannot form in those solar systems there is always the possibility that the massive stars capture some rogue planets. There are calculations that many of the planets in the Milky Way are rogue planets. Those planets are formed of nova or supernova remnants after their star exploded as nova or supernova. 

Or the eruption of their star pushed those planets away from their orbiter. Maybe Pluto and most of the Kuiper Belt asteroids are turning to interstellar travelers after the Sun erupted nova when it used its fuel.

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
