In microgravity conditions it was possible to create quantum gas On board the ISS there is a combined laboratory designed to create the coldest substances in the Universe. This is the Cold Atom Laboratory, which gives scientists the opportunity to study the quantum properties of atoms in zero-gravity conditions. On November 15, scientists announced the achievement of an important result. Controlled remotely by a team at NASA's Jet Propulsion Laboratory, the Cold Atom Laboratory created a quantum gas containing two kinds of atoms. This result opens up new possibilities for conducting space experiments in the field of quantum chemistry. [caption id="attachment_83199" align="aligncenter" width="650"] ISS[/caption] Matter can exist in five known states: gaseous, liquid, solid, plasma and Bose-Einstein condensate - an exotic fifth state of matter discovered in the 1990s. Bose-Einstein condensates do not occur in nature, but scientists can create them. This is done in ultra-cold laboratories, similar to the Cold Atom Laboratory, where lasers or magnets are used to cool a cloud of atoms to near absolute zero, which is −459.67°F (−273.15°C). In the Bose-Einstein condensate state, atoms slow down, allowing scientists to observe rare quantum effects. On Earth, gravity causes the Bose-Einstein condensate to collapse when the magnets or lasers needed to create it are turned off. However, this does not happen in microgravity conditions in space. In 2018, scientists were already able to create a Bose-Einstein condensate at the Cold Atom Laboratory after installation on the ISS. They have been researching this phenomenon in recent years. An exotic fifth state of matter with two types of atoms was created in a quantum chemistry experiment on the ISS Now researchers have been able to show that they can create such a quantum gas with not only one, but two types of atoms. To do this, they used pairs of potassium-rubidium atoms. Representatives from NASA's Jet Propulsion Laboratory said that further work with this type of quantum gas could be useful for the development of space quantum technologies already used on Earth. “It becomes possible to create extremely sensitive sensors and use cold atoms in the Bose-Einstein condensate to create gyroscopes. Such gyroscopes can serve as a fulcrum for space navigation in deep space. Also being considered are ideas leading to more accurate space clocks, which have important implications for areas such as high-speed Internet and GPS,” said Nicholas Bigelow, a professor of physics and optics at the University of Rochester, one of the co-authors of the discovery. The researchers hope that future experiments at the Cold Atom Laboratory will help test the equivalence principle, which is fundamental to Albert Einstein's theory of general relativity. According to this principle, gravity should affect all objects equally, regardless of their mass. Scientists have difficulty reconciling this principle with the laws of quantum mechanics, which describe the behavior of the smallest objects in the Universe. They hope that quantum experiments in space will make it possible to more accurately test this principle.

The #research for the possibility of life on the #planet #Mars is not over, now #scientists had hoped under the surface of Mars (Subsurface) there could be #reserves of liquid water. Confirmation of this has been found from Mars Express of the #European_Space_Agency (ESA) which has found signs of liquid water on Mars.

Liftoff of Orbital ATK Cargo Mission to International Space Station

The Orbital ATK Cygnus pressurized cargo module is carried atop the United Launch Alliance Atlas V rocket as it launches from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida. Orbital ATK's seventh commercial resupply services mission, CRS-7, will deliver 7,600 pounds of supplies, equipment and scientific research materials to the International Space Station. Liftoff was at 11:11 a.m. EDT on Tuesday, April 18, 2017. At about 6:05 a.m. EDT on Saturday, April 22, Expedition 51 astronauts Thomas Pesquet of ESA (European Space Agency) and Peggy Whitson of NASA will use the space station’s robotic arm to grapple Cygnus, which will be installed on the Unity module.

Airbus consegna il primo strumento Sentinel-5 per l'integrazione satellitare Airbus Defence and Space ha consegnato all’Agenzia Spaziale Europea (ESA) il primo strumento Sentinel-5 che sarà integrato sul satellite MetOp A di seconda generazione. Lo strumento UVNS (Ultraviolet Visible Near-infrared Short-wave infrared Spectrometer) contribuirà a migliorare il monitoraggio della qualità dell’aria, dei cambiamenti nello strato di ozono e delle emissioni da incendi boschivi. Sentinel-5 è una delle cosiddette “sentinelle atmosferiche”, costruite per rispondere a domande relative alla composizione dell’atmosfera terrestre: la sua missione è quella di monitorare globalmente la distribuzione dei gas in traccia e degli aerosol atmosferici (particolato) su base operativa a lungo termine, a sostegno del programma di

The James Webb Telescope helped observe the disappearance of the disk around the young star SZ Cha Data obtained with the James Webb Space Telescope (JWST) allowed us to draw conclusions about the process of planet formation in gas-dust disks. It turns out that the amount of ionized neon in these disks can serve as an indicator of the rate of planet formation. Previously, astronomers have already observed disks of gas and dust around young stars, but the process of their formation takes a very long time - hundreds of thousands, or even millions of years. It is almost impossible to observe changes in disks over short time intervals. In a new study, James Webb was able to detect changes in one of these disks where planet formation occurs. In observations made by a team led by Catherine Espaillat in 2008 using NASA's Spitzer Telescope, an infrared spectral line associated with doubly ionized neon ([Ne III]) was seen. The signal came from a disk of gas and dust around the young star SZ Chamaeleontis (SZ Cha).  [caption id="attachment_82600" align="alignnone" width="780"] James Webb[/caption] James Webb Helps Find Key to the Rate of Planet Formation When an atom collides with a photon, it becomes "ionized" and "doubly ionized" atoms lose two electrons. In the SZ Cha disk, the amount of doubly ionized neon appears to be very low compared to disks typically exposed to X-ray emission from young stars. The appearance of this neon indicated that the dominant type of radiation in the SZ Cha system was "extreme ultraviolet" (EUV) radiation, capable of destroying gas and dust in the protoplanetary disk, but not as quickly as X-rays. X-ray radiation destroys the protoplanetary disk 100 times faster than ultraviolet radiation. From this we can conclude that the rate of “evaporation” of the disk and, accordingly, the time during which the formation of planets is possible depends on the energy and type of radiation.  In 2023, Espaillat and her team conducted a new long-term observation of the SZ Cha system using JWST's MIRI instrument. The scientists found that the amount of doubly ionized neon was significantly reduced compared to singly ionized neon. Additional observations using ground-based telescopes allow us to study the properties of protoplanetary disks in even more detail. For example, the CHIRON spectrometer on the SMARTS telescope at Cerro Tololo Observatory measured the blueshift of alpha hydrogen from the star SZ Cha. The blue shift is a Doppler-type change that indicates that something is moving toward our detectors, in this case hydrogen. Scientists interpret this phenomenon as a "stellar wind" of particles emanating from the star. This wind is thought to be dense enough to absorb ultraviolet radiation, but still transmits X-rays, indicating the latter's dominance in the evolution of this star system.  The discovery of doubly ionized neon in 2008, but its absence in subsequent observations, supports the assumption of X-ray dominance in the SZ Cha system. Thus, the amount of doubly ionized neon can serve as an indicator of ultraviolet and X-ray radiation affecting the protoplanetary disk. Astronomers can use this value to more accurately determine the time it takes planets to form in such a system before their disk disappears.
