The first South Korean lunar probe sent the first photo of the Earth and the Moon

The Danuri probe, which became South Korea's first lunar probe, sent back to Earth the first image of the Earth and the Moon. Thus, engineers confirmed the functionality of the camera, which examined the far side of the Moon from an unusual distance, according to the website of the Korean Astronomy and Space Science Institute… Continue reading The first South Korean lunar probe sent the first photo of the Earth and the Moon

Physicists have proven the importance of the mesoscale for quantum phase transitions

Low-temperature phase transitions in ferromagnets are characterized by destruction of the domain structure. In an article in Nature physicists write that for a theoretical description of the dynamics of such transitions, it is necessary to take into account not only microscopic, but also mesoscale symmetry. This discovery indicates the possibility of the existence of non-classical… Continue reading Physicists have proven the importance of the mesoscale for quantum phase transitions

Physicists were able to obtain acoustic frequency combs at 10 gigahertz

American physicists have manufactured a hybrid system from a nonlinear oscillatory circuit and an acoustic resonator connected by a piezoelectric contact. This combination made it possible to impart nonlinearity to acoustic modes at a frequency of 10 gigahertz. The authors were able to generate coherent acoustic frequency combs in their setup, which will help combat… Continue reading Physicists were able to obtain acoustic frequency combs at 10 gigahertz

Archaeologists have discovered a bronze figurine of Jupiter in Taman

Archaeologists explored the ancient settlement of Red October-1, located in Taman. As a result of this work, they established that the fortified settlement arose at the turn of the 6th–5th centuries BC and existed until the modern era. Among the rare artifacts discovered at this site were a gray clay lamp in the shape of… Continue reading Archaeologists have discovered a bronze figurine of Jupiter in Taman

Metasurfaces emit entangled photons with variable wavelengths

American and German physicists have fabricated thin metasurfaces consisting of arrays of silicon nanocavities that exhibit spontaneous parametric scattering. They showed that such structures are capable of generating entangled photons. Unlike traditional media used for this, metasurfaces have greater flexibility, which allows the wavelength of the resulting photons to be changed by changing the pump… Continue reading Metasurfaces emit entangled photons with variable wavelengths

Supernova 1181 fits the model of the merger of two white dwarfs

Astronomers from six countries have confirmed the idea that supernova SN 1181 AD, which exploded in 1181, represents the second remnant of a rare type of Iax supernova confirmed in the Milky Way. It is assumed that two carbon-oxygen white dwarfs or a massive carbon-oxygen dwarf with a helium companion merged without the resulting white… Continue reading Supernova 1181 fits the model of the merger of two white dwarfs

The Event Horizon Telescope saw the bend of the distant blazar's jet

The Event Horizon Telescope (EHT) has captured the most detailed image yet of the interior of the relativistic jet blazar J1924-2914, whose light took 3.5 billion years to reach Earth. It turned out that as it moves away from the core, the jet begins to bend, and toroidal magnetic fields can act in the region… Continue reading The Event Horizon Telescope saw the bend of the distant blazar's jet

One atom emits fourteen entangled photons

German physicists have reported the successful generation of entangled multiqubit states on photons using a single atom placed in a cavity. They managed to involve 12 photons in the creation of cluster states, and 14 photons of Greenberger-Horn-Zeilinger states. The frequency of generation and detection of entangled photonic chains based on the proposed scheme turned… Continue reading One atom emits fourteen entangled photons

People used different parts of the brain when thinking about their inner circle and other people they knew.

People use different parts of the brain when they think about their family and closest friends and the rest of their social circle, scientists from Israel and the UK have found. In the first case, parts of the brain that are responsible for processing the mental state are activated, and in the second, those associated… Continue reading People used different parts of the brain when thinking about their inner circle and other people they knew.

Physicists saw Rabi oscillations using extreme ultraviolet light

European physicists have reported the observation of characteristic doublets in the spectra of electrons knocked out of helium atoms by coherent light in the extreme ultraviolet range. The result obtained indicates the occurrence of Rabi oscillations in atoms. The shape and position of the doublets could be theoretically reproduced only after taking into account the… Continue reading Physicists saw Rabi oscillations using extreme ultraviolet light
