The first habitable-zone Earth-sized planet has found by TESS

The first habitable-zone Earth-sized planet has found by TESS ( Transiting Exoplanet Survey Satellite) has been found the Earth-sized exoplanet at the habitable zone of the star. The star is an M-type star, what surface temperature is about 3000 kelvin and that means the planet is locked, and it turns always the same side to the star. The name of the planet is TOI-700d, and the planet is a potential host for life. So the name of the star is TOI-700 and there are three planets. The surface temperature of TOI-700d is about 268 kelvin (-5,5 C).

If there is liquid water on the surface of that planet, it would create clouds, what might keep its surface temperature lower at the dayside, and if there is an atmosphere, what is another requirement for the life, that means that the cold nightside will cool the temperature of the planet. So there is a possibility that the planet is hosting some kind of lifeforms.

When we are thinking about the M-type dwarfs the planets of their habitable zone are locked. The M-type stars are also flare-stars, which means that they are erupting sometimes very hard. But the fact is that those planets that are hosting life should have an atmosphere, liquid water, and magnetic field.

So the clouds that are rising from the water are cooling the dayside. And the freezing nightside can keep the temperature of that planet lower. The last thing is that the magnetic field would also push the particles coming from the star away from the surface of that planet. The flares of the flare stars are seeming impressive, but the eruptions are not lasting a very long time. And the surface temperature of the star is very low, so we cannot just copy the data of the Sun to that star and its planets.

Plasmonic waves can make new waves in quantum technology.

"LSU researchers have made a significant discovery related to the fundamental properties and behavior of plasmonic waves, which can lead ot the development of more sensitive and robust quantum technologies. Credit: LSU" (ScitechDaily, Plasmonics Breakthrough Unleashes New Era of Quantum Technologies) Plasmonic waves in the quantum gas are the next-generation tools. The plasmonic wave is quite similar to radio waves. Or, rather say it, a combination of acoustic waves and electromagnetic waves. Quantum gas is an atom group. In those atom groups, temperature and pressure are extremely low. The distance of atoms is long. And when an electromagnetic system can pump energy to those atoms. But the thing in quantum gas is that the atoms also make physical movements like soundwaves. It's possible. To create quantum gas using monoatomic ions like ionized noble gas. In those systems, positive (or negative) atoms push each other away. When the box is filled with quantum gas and som

Metamaterials can change their properties in an electric- or electro-optical field.

"Researchers have created a novel metamaterial that can dynamically tune its shape and properties in real-time, offering unprecedented adaptability for applications in robotics and smart materials. This development bridges the gap between current materials and the adaptability seen in nature, paving the way for the future of adaptive technologies. Credit: UNIST" (ScitechDaily, Metamaterial Magic: Scientists Develop New Material That Can Dynamically Tune Its Shape and Mechanical Properties in Real-Time) Metamaterials can change their properties in an electric- or electro-optical field. An electro-optical activator can also be an IR state, which means. The metamorphosis in the material can thermally activate. AI is the ultimate tool for metamaterial research. Metamaterials are nanotechnical- or quantum technical tools that can change their properties, like reflection or state from solid to liquid when the electric or optical effect hits that material. The metamaterial can cru
