New Earth-mass exoplanet found near red dwarf.

"Artist’s conception of a rocky Earth-mass exoplanet like Wolf 1069 b orbiting a red dwarf star.

The new exoplanet Wolf 1069 b is a giant Earth-mass rocky planet. The new exoplanet orbits red dwarf Wolf 1069 in the habitable zone. The location of Wolf 1069 is in the Cygnus constellation. The surface temperature of that star is 3158±54K or 2884,85±54C.

That means this M5 spectral class red dwarf is a very small, and cold object if we compare it with the Sun. And, its solar system is also small.

The distance between Earth and Wolf 1069 is 31.229 ly. So, it's quite near to us. The exoplanet trajectory fits in Mercury's trajectory. If we want to compare that Wolf 1069 system with our solar system. But the star is much colder than the sun. And that means the shell of that planet is not melting to lava.

And that means there could be liquid water. The planet itself is locked. So there are no similar lifeforms that exist on Earth. The problem is that the dayside of those locked planets is extremely hot.

The nightside of locked exoplanets is very cold. Powerful winds are blowing on its surface. And those winds are stabilizing temperature on locked planets. That means that liquid water is possible on those planets.

Many other variables determine if liquid water is possible. The one thing is the atmosphere. First, the planet must have an atmosphere where liquid water can exist on it.

Then the gravitational field's strength must be right. If the gravitational field is too strong it pulls water to ice. If the gravitational field is too weak. Water boils in low temperatures.

So if the planet's gravitational field is strong, water can stay liquid on hotter planets. But that means the planet must stay closer to its star than a weak gravitational planet.

Same way weak gravity means that the melting point of water is lower. That means on the planets which gravitational fields water can stay liquid in a lower atmosphere.

Water itself doesn't guarantee that the planet can host life. If the chemical environment doesn't contain elements that amino acids include the lifeforms cannot form on that planet. Also if water boils at a low temperature that can affect the ability to form proteins. High temperatures can also affect the ability to form complicated molecules. The terms "lifeforms" and "intelligent lifeforms" are not synonyms.

Things like amoebas and diatoms are life forms. But they are not intelligent lifeforms. Intelligent lifeforms require time to advance. An intelligent lifeform doesn't mean. That it can build rockets and airplanes immediately.

Culture and technology require time to develop. And, of course, species require motivation to create technology. So even if some planet hosts intelligent lifeforms, those lifeforms would not necessarily have the technology. So, technically advanced lifeforms and intelligent lifeforms are not synonyms either.

By the way, if we are thinking about intelligent creatures that could live on locked planets. Those creatures must live in the nightside of those planets. That means those creatures would have big eyes. And they would like to be in the night rather than dayside. So that is one remarkable thought that so-called "grey men" are forming in my mind.

Living at night or in low-level light requires big eyes. And those creatures would be very sensitive to sunlight.

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

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

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
